Esta página explica a sintaxe de imagem quando editar a wiki. Você, ou outro utilizador, terão de enviar primeiro uma imagem antes de poder utilizá-la numa página.

As imagens armazenadas num servidor MediaWiki são normalmente apresentadas usando o prefixo de espaço nominal File: (embora o anterior Image: continue a ser suportado como sinónimo) como destino de um link no MediaWiki. O espaço nominal alternativo Media: também pode ser usado para referir o conteúdo do ficheiro original (para apresentação ou para fazer o download em separado, fora de uma página do MediaWiki).

Requisitos

Before using images in your page, the system administrator of your wiki must have enabled file uploads and a user has to upload the file. System administrators may also set the wiki to accept files from foreign repositories, such as the Wikimedia Commons. For server side image resizing it is necessary to have a scaler configured (such as GD2, ImageMagick, etc.).

Tipos de multimédia suportados para as imagens

Os seguintes formatos de ficheiro são suportados por predefinição:

  • .jpg ou .jpeg - imagem em mapa de bits (bitmap), comprimida no formato padronizado JPEG (este formato de compressão com perdas é mais apropriado para fotografias).
  • .png - imagem em mapa de bits, no formato Portable Network Graphics (especificado pelo W3 Consortium).
  • .gif - imagem em mapa de bits no formato obsoleto Graphics Interchange Format.
  • .webp - WebP supports both lossy and lossless compression while reducing image size by up to 45%.

Outros formatos usados na Wikimedia e frequentemente permitidos noutros sítios (podem exigir configuração extra, para além daquilo que é ativado por padrão):

  • .svg - imagem redimensionável no formato Standard Vector Graphics (especificado pelo W3 Consortium). Consulte Manual:Image Administration#SVG.
  • .tiff - Imagem em formato etiquetado. Frequentemente usado para fotografias de arquivo, de alta resolução. Utilizado frequentemente com Extension:PagedTiffHandler .
  • .ogg, .oga, .ogv - Multimédia (áudio ou vídeo) no formato Ogg. Não é formato de imagem, mas tem tratamento semelhante. Frequentemente usado com Extension:TimedMediaHandler
  • .pdf - documentos de várias páginas no formato Portable Document Format (inicialmente especificado pela Adobe). Frequentemente usado em conjunto com Extension:PdfHandler .
  • .djvu - documentos de várias páginas em mapa de bits no formato DejaVu (normalmente, digitalizações de livros). Consulte Manual:How to use DjVu with MediaWiki
    Só é apresentada uma página de um ficheiro .pdf ou .djvu de cada vez.

Podem ser suportados outros tipos de ficheiros multimédia, mas poderá não ser possível apresentá-los em linha nas páginas.

Apresentação de uma imagem

Sintaxe

A sintaxe completa para mostrar uma imagem é: 

[[File:filename.extension|options|caption]]

onde «opções» pode ser nenhuma, uma, ou mais das seguintes, separadas por uma barra vertical (|):

  • Opção do formato: um de entre border e/ou frameless, frame ou thumb (ou thumbnail). Note: border can be used in combination with frameless but will be ignored if used with one of the other options.
    Controla a forma como a imagem apresentada é formatada e incorporada no resto da página.
    • {width}px — Resizes the image to fit within the given maximum width in pixels, without restricting its height.

(Only whole-number pixel values are supported. A space character between the width value and "px" is permitted.)

    • x{height}px — Resizes the image to fit within the given maximum height in pixels, without restricting its width.

Only whole-number pixel values are supported. A space character between the height value and "px" is permitted.

    • {width}x{height}px — Resizes the image to fit within the given width and height in pixels.

Only whole-number pixel values are supported. A space character between the width value and "px" is permitted.

    • upright — Resizes an image to a multiple of the user's thumbnail size preferences (see $wgThumbLimits ) – or the default thumbnail size, for logged-out users or logged-in users who have not changed their preferences – to fit within reasonable dimensions. This option is often useful for images whose height is larger than their width. Requires either thumb or frameless. Setting |upright=1.0| will display the image at the user's default image width. |upright=2.0| will display the image at double the user's default width.
  • The image will always retain its aspect ratio.
  • Images in non-scalable media types can be reduced in size, but not increased; e.g., bitmap images cannot be scaled up.
  • The upright setting does not require an equals sign, i.e. |upright 2.0| works the same as |upright=2.0|.
  • When used without a value or an equals sign (e.g., |upright|), defaults to |upright=0.75| (although |upright=| is the same as |upright=1.0|)
  • The default maximum size depends on the format and the internal image dimensions (according to its media type).

If multiple of these options are present, only the first one will be used

  • Controls the horizontal alignment (and inline/block or floating styles) of the image within a text (no default value).
  • Vertical alignment option: one of baseline, sub, super, top, text-top, middle, bottom, text-bottom
  • Controls the vertical alignment of a non-floating inline image with the text before or after the image, and in the same block (the default vertical alignment is middle).
    • link={target} — Allows to change the target (to an arbitrary page title, or URL) of the generated link, activable on the rendered image surface; e.g. [[File:Example.jpg|20px|link=http://www.wikipedia.org]] renders as (external link), or [[File:Example.jpg|20px|link=MediaWiki]] renders as (internal link).
    • link= (with an empty value) — (MediaWiki 1.14+) Displays an image without any activable link; e.g. [[File:Example.jpg|20px|link=]] renders as .
  • If there is a space character between link and the equals sign, the link statement will be treated as a caption.
  • Including some HTML character equivalents, like %22 for ", can cause the link statement to be treated as a caption (see phabricator:T306216).
  • ! for MW 1.24 and lower: If you set |link=| (empty), then no title will be rendered. (See phabricator:T23454.)
  • Other specific options:
    • alt={alternative text} — (MediaWiki 1.14+) Defines the alternative text (maps to the HTML attribute alt="..." of the generated ‎<img /> element) of an image that will be rendered if either the referenced image cannot be downloaded and embedded, or if the support media must use the alternative description text (e.g. when using a Braille reader or with accessibility options set by the user in its browser).
  • If there is a space character between alt and the equals sign, the alt statement will be treated as a caption.
    • page={number} — Renders the specified page number (currently only applicable when showing a .djvu or .pdf file).
    • thumbtime={number} — Renders a thumbnail from the video at the specified timestamp in seconds or MM:SS or HH:MM:SS format (only applicable when showing a video file).
    • start={number} — When video playback is started it will start at the specified timestamp in seconds or MM:SS or HH:MM:SS format (only applicable when showing a video file).
    • muted — When media playback is started, audio will be muted.
    • loop — Media will loop continuously. (only applies to audio and video)
    • lossy={false} — (PagedTiffHandler ) For using PNG instead of JPG thumbnails for Tiff images
    • class={html class} — (MediaWiki 1.20+)Defines classes (maps to the HTML attribute class="..." of the generated ‎<span>...‎</span> element wrapped around the ‎<img /> element).
      Default behavior since MediaWiki 1.40, optional since MediaWiki 1.36.[1] Previously the class was applied directly to the ‎<img /> element.[2]
    • lang={language code} — (MediaWiki 1.22+) For SVG files containing <switch> statements varying on a systemLanguage attribute, selects what language to render the file in. The default is the page language (defaults to project default language on most projects).

If a parameter does not match any of the other possibilities, it is assumed to be the caption text. If more than one non-parameter string is present, the final non-parameter string will be used as the caption. Caption text shows below the image in thumb and frame formats, or as tooltip text in any other format. Caption text displayed in the thumb and frame formats may contain wiki links and other formatting. MediaWiki extensions can add additional options.

If 'alt' is not specified and a caption is provided, the alternative text will be created automatically from the caption, stripped of formatting, except when in thumb or frame mode since the caption is already readable by screen readers in that case.

When the height of an image in thumbnail is bigger than its width (i.e. in portrait orientation rather than landscape) and you find it too large, you may try the option upright=N, where N is the image's aspect ratio (its width divided by its height, defaulting to 0.75). The alternative is to specify the desired maximum height (in pixels) explicitly.

Note that by writing thumb={filename}, you can use a different image for the thumbnail.

Size and frame

Among different formats, the effect of the size parameter may be different, as shown below.

  • For how it appears when its size is not specified, see Format section above.
  • When the format is not specified, or only bordered, the size can be both reduced and enlarged to any specified size.
  • In the examples below, the original size of the image is 400×267 pixels.
  • An image with frame always ignores the size specification; the original image will be reduced if it exceeds the maximum size defined in user preferences, and the page information will display a Linter error.
  • The size of an image with thumb or frameless can be reduced, but cannot be enlarged beyond the original size of the image.

Alinhamento vertical

The vertical alignment options take effect only if the image is rendered as an inline element and is not floating. They alter the way the inlined image will be vertically aligned with the text present in the same block before and/or after this image on the same rendered row.

Note that the rendered line of text where inline images are inserted (and the lines of text rendered after the current one) may be moved down (this will increase the line-height conditionally by additional line spacing, just as it may occur with spans of text with variable font sizes, or with superscripts and subscripts) to allow the image height to be fully displayed with this alignment constraint.

To show the alignment result more clearly, the text spans are overlined and underlined, the font-size is increased to 200%, and the paragraph block is outlined with a thin border; additionally images of different sizes are aligned:

text top: text

text text-top: text

text super: text

text baseline: text

text sub: text

text default: text

text middle: text

text text-bottom: text

text bottom: text

Notas:

  1. The "middle" vertical alignment position of the image (which is also the default) usually refers to the middle between the x-height and the baseline of the text (on which the vertical middle of the image will be aligned, and on which usually the text may be overstroke), but not to the middle of the line-height of the font-height that refers to the space between the "text-top" and "text-bottom" positions ; the font-height excludes:
    • the additional line separation spacing normally divided equally into two line-margins (here 0.5em, according to line-height set to 200%) above and below the font-height).
    • the additional line spacing which may be added by superscripts and subscripts.
  1. However, if the image height causes its top or bottom position to go above or below the normal full line-height of text, the middle position will be adjusted after the increasing the top and/or bottom line-margins so that the image can fit and align properly, and all images (including those with smaller heights) will be vertically centered on the adjusted middle position (for computing the effective line-height, the text of each rendered row with the larger font-height will be considered).
  1. The "text-top" and "text-bottom" alignment positions also excludes the extra line spacing added by superscripts and subscripts, but not the additional line-spacing defined by the line-height.
  1. The "top" and "bottom" alignment positions take into account all these extra line spacings (including superscripts and subscripts, if they are present in a rendered line span).

When the image alignment constrains the image to grow above or below the normal line-spacing, and the image is not absolutely positioned, the image will cause the "top" and "bottom" positions to be adjusted (just like superscripts and subscripts), so the effective line-height between rendered lines of text will be higher.

  1. The "underline", "overline" and "overstrike" text-decoration positions should be somewhere within these two limits and may depend on the type and height of fonts used (the superscript and subscript styles may be taken into account in some browsers, but usually these styles are ignored and the position of these decorations may not be adjusted); so these decorations normally don't affect the vertical position of images, relatively to the text.

Stopping the text flow

On occasion it is desirable to stop text (or other inline non-floating images) from flowing around a floating image. Depending on the web browser's screen resolution and such, text flow on the right side of an image may cause a section header (for instance, == My Header ==) to appear to the right of the image, instead of below it, as a user may expect. The text flow can be stopped by placing <div style="clear: both"></div> before the text that should start below the floating image. (This may also be done without an empty line by wrapping the section with the floating images with <div style="overflow: hidden">…</div>, which clears all floats inside the div element.)

All images rendered as blocks (including non-floating centered images, left- or right-floating images, as well as framed or thumbnailed floating images) are implicitly breaking the surrounding lines of text (terminating the current block of text before the image, and creating a new paragraph for the text after them). They will then stack vertically along their left or right alignment margin (or along the center line between these margins for centered images).

The following table shows how to alter the link target (whose default is the image description page ) or how to remove it. Changing the link does not alter the format described in the previous sections.

Aviso:

The licencing requirements on your wiki may not allow you to remove all links to the description page that displays the required authors attributions, the copyrights statements, the applicable licencing terms, or a more complete description of the rendered image (including its history of modifications).
If you change or remove the target link of an image, you will then have to provide somewhere else on your page an explicit link to this description page, or to display the copyright and author statement and a link to the applicable licence, if they are different from the elements applicable to the embedding page itself.
Your wiki policy may restrict the use of the alternate link parameter, or may even enforce a prohibition of alternate link parameters for embedded media files (in which case, the link parameter will be ignored), or may only accept them after validation by authorized users or administrators.

Renderizar uma galeria de imagens

Sintaxe da galeria

It's easy to make a gallery of thumbnails with the ‎<gallery> tag. A sintaxe é: 

<gallery>
File:file_name.ext|caption|alt=alt language
File:file_name.ext|caption|alt=alt language
{...}
</gallery>

Note that the image code is not enclosed in brackets when enclosed in gallery tags.

Captions are optional, and may contain wiki links or other formatting.

The words "center", "left", and "right" used as captions cause false-positive Linter errors. See task T275074 for details.

Some of the parameters controlling thumb output can also be used here, specifically the ones that modify the file (as opposed to ones that control where in the page the image falls). For example, with multi-paged media like pdfs, you can use code like page=4 and with videos you can use thumbtime=10.

The File: prefix can be omitted. However, it is helpful to include it as an aid for quickly locating image specifiers in the wikitext (for example, when cleaning up page layout).

If the image links to an external site, the caption must come before the link parameter or the caption will not render.

Por exemplo: 

<gallery>
File:Example.jpg|Item 1
File:Example.jpg|a link to [[Help:Contents]]
File:Example.jpg
File:Example.jpg|alt=An example image. It has flowers
File:Example.jpg|''italic caption''
File:Example.jpg|link=https://example.com|This text will not render because an external link came first
File:Example.jpg|Links to external website|link=https://example.com
File:Example.jpg|link=w:Main_Page|Internal link
Example.jpg|on page "{{PAGENAME}}"
File:Using Firefox.pdf|page=72
</gallery>

is formatted as:

  • Item 1
    Item 1
  • a link to Help:Contents
    a link to Help:Contents
  • An example image. It has flowers
  • italic caption
    italic caption
  • Links to external website
    Links to external website
  • Internal link
    Internal link
  • on page "Images/pt"
    on page "Images/pt"

mode parameter

Versão MediaWiki:
≥ 1.22

Starting in MediaWiki version 1.22 a mode parameter is available, taking options as follows:

  • traditional is the original gallery type used by MediaWiki.
  • nolines is similar to traditional, but with no border lines.
  • packed causes images to have the same height but different widths, with little space between the images.

The rows in this responsive mode organize themselves according to the width of the screen.

  • packed-overlay shows the caption overlaid on the image, in a semi-transparent white box.
  • packed-hover is similar to packed-overlay, but with the caption and box only showing up on hover.
  • slideshow creates a slideshow of the images.

Por exemplo: 

<gallery mode="packed-hover">

Atributos opcionais da galeria

The gallery tag itself takes several additional parameters, specified as attribute name-value pairs: 

<gallery {parameters}>
{images}
</gallery>
  • caption="{caption}": (caption text between double quotes for more than one word) sets a caption centered atop the gallery. Only plain text may be used in the caption; formatting, templates and the like will not work.
  • widths={width}: sets the (max) widths of the images in pixels; the default value is 120px.

(It has no effect if mode is set to one of the following: packed, packed-overlay, packed-hover, slideshow.) Note the plural: widths.

  • heights={heights}: sets the (max) heights of the images in pixels; the default value is 120px.

(It has no effect if mode is set to slideshow.)

  • perrow={integer}: sets the number of images per row.

(It has no effect if mode is set to one of the following: packed, packed-overlay, packed-hover, slideshow.) The default is perrow=0 which automatically adjusts the number of images per row based on width of screen.

  • showfilename={anything}: Show the filenames of the images in the individual captions for each image (1.17+).
  • mode={traditional|nolines|packed|packed-hover|packed-overlay|slideshow}: See section above (1.22+; 1.28+ for "slideshow").
  • showthumbnails: For "slideshow" mode only, display the strip with image thumbnails below the slideshow by default (1.29+).
  • Any html attribute allowed on a <ul> tag (e.g. id, title, class)
For packed (and related) modes the widths parameter has no effect and the heights parameter determines the minimum height of the images. Packed modes will adjust the width of images in order to make each row the same length (unless a row has too few images to do this without overly enlarging the images).

Row of images that will wrap to browser width

One way that works for a row of images with varying widths is not to use "thumb" or "left" or "none". If "thumb" is not used (and thus no captions) a row of images will wrap to the browser width. If necessary, narrow the browser window to see the images wrap to the next row. 

[[File:Example.jpg|220px]]
[[File:Example.jpg|100px]]
[[File:Example.jpg|150px]]
[[File:Example.jpg|250px]]
[[File:Example.jpg|200px]]
[[File:Example.jpg|50px]]
[[File:Example.jpg|220px]]
[[File:Example.jpg|175px]]

To wrap images of varying widths with captions it is necessary to use div HTML for an unordered list. Along with style="display: inline-block;". For more info and ideas see: Give Floats the Flick in CSS Layouts. 

<div><ul> 
<li style="display: inline-block;"> [[File:Example.jpg|thumb|none|220px|Caption 1]] </li>
<li style="display: inline-block;"> [[File:Example.jpg|thumb|none|100px|Caption 2]] </li>
<li style="display: inline-block;"> [[File:Example.jpg|thumb|none|150px|Caption 3]] </li>
<li style="display: inline-block;"> [[File:Example.jpg|thumb|none|250px|Caption 4]] </li>
<li style="display: inline-block;"> [[File:Example.jpg|thumb|none|200px|Caption 5]] </li>
<li style="display: inline-block;"> [[File:Example.jpg|thumb|none|50px|Caption 6]] </li>
<li style="display: inline-block;"> [[File:Example.jpg|thumb|none|220px|Caption 7]] </li>
<li style="display: inline-block;"> [[File:Example.jpg|thumb|none|175px|Caption 8]] </li>
</ul></div>
  • Caption 1
  • Caption 2
  • Caption 3
  • Caption 4
  • Caption 5
  • Caption 6
  • Caption 7
  • Caption 8

To align the top edge of images add the vertical-align command 

<div><ul> 
<li style="display: inline-block; vertical-align: top;"> [[File:Example.jpg|thumb|none|220px|Caption 1]] </li>
<li style="display: inline-block; vertical-align: top;"> [[File:Example.jpg|thumb|none|100px|Caption 2]] </li>
<li style="display: inline-block; vertical-align: top;"> [[File:Example.jpg|thumb|none|150px|Caption 3]] </li>
<li style="display: inline-block; vertical-align: top;"> [[File:Example.jpg|thumb|none|250px|Caption 4]] </li>
<li style="display: inline-block; vertical-align: top;"> [[File:Example.jpg|thumb|none|200px|Caption 5]] </li>
<li style="display: inline-block; vertical-align: top;"> [[File:Example.jpg|thumb|none|50px|Caption 6]] </li>
<li style="display: inline-block; vertical-align: top;"> [[File:Example.jpg|thumb|none|220px|Caption 7]] </li>
<li style="display: inline-block; vertical-align: top;"> [[File:Example.jpg|thumb|none|175px|Caption 8]] </li>
</ul></div>
  • Caption 1
  • Caption 2
  • Caption 3
  • Caption 4
  • Caption 5
  • Caption 6
  • Caption 7
  • Caption 8

Some wiki farms do not have all gallery options (such as "widths"). Also, sometimes one wants varying widths for images in a row. Outside of a gallery, or the div HTML, it is impossible to have individual captions for images in a row of images that will wrap to the browser width. Try it and see. Nothing else using wikitext works correctly. Images will either overlap stuff on the right, or force a horizontal scroll bar.

Using a left float ("left") for some images, combined with "none" for some of the images, will not work consistently either, especially if there is also a right sidebar of images. Weird things will occur. At narrower browser or screen widths an image out of the row may appear far down the page after the end of the right sidebar of images.

Comportamento de vinculação

Por predefinição, uma imagem é vinculada à sua página de descrição do ficheiro. The "link=" option modifies this behavior to link to another page or website, or to turn off the image's linking behavior.

Alternatively, you can create a text link to a file description page or to the file itself. Consulte Help:Linking to files .

Display image, link it to another page or website

Use "link=" option to link image to another page or website:

Clicking on the below image will take you to MediaWiki: 

[[File:MediaWiki-2020-logo.svg|50px|link=MediaWiki]]

Clicking on the below image will take you to example.com: 

[[File:MediaWiki-2020-logo.svg|50px|link=http://example.com]]

Use "link=" option with no value assigned to turn link off entirely; the below image is not a link: 

[[File:MediaWiki-2020-logo.svg|50px|link=]]

Vincular a uma imagem

Add : as a prefix to the link you need to create. 

[[:File:MediaWiki-2020-logo.svg]]

File:MediaWiki-2020-logo.svg 

[[:File:MediaWiki-2020-logo.svg|Wiki]]

Wiki

Directly linking to an image

The above examples link to the image's description page. To directly link to an image, the pseudo-namespace Media: can be used on MediaWiki pages: 

[[Media:MediaWiki-2020-logo.svg]]

Media:MediaWiki-2020-logo.svg

Another possibility is to use the Special:Redirect/file page (or its alias Special:Filepath). Unlike the above example, you can link to it from external websites as well as from MediaWiki pages. 

[[Special:Redirect/file/Wikipedia.png]]

The parameters height and width can also be added to return a specific size of the image. The image aspect ratio is always preserved. 

https://www.mediawiki.org/w/index.php?title=Special:Redirect/file/Wikipedia.png&width=100&height=100

Obtaining the full URL of an image

To obtain the full path of an image (without going through redirects as shown above), some Palavras Mágicas can be used. 

{{filepath:MediaWiki-2020-logo.svg}}

Becomes:

//upload.wikimedia.org/wikipedia/commons/d/dd/MediaWiki-2020-logo.svg

In the event that this is used from a template where the File: namespace needs to be removed, {{PAGENAME}} can do so: 

{{filepath:{{PAGENAME:File:MediaWiki-2020-logo.svg}}}}

Becomes:

//upload.wikimedia.org/wikipedia/commons/d/dd/MediaWiki-2020-logo.svg

Ficheiros em outros sites da Web

You can link to an external file available online using the same syntax used for linking to an external web page. With these syntaxes, the image will not be rendered, but only the text of the link to this image will be displayed. 

[http://url.for/some/image.png]

Or with a different displayed text: 

[http://url.for/some/image.png link text here]

Additional MediaWiki markup or HTML/CSS formatting (for inline elements) is permitted in this displayed text (except for embedded links that would break the surrounding link): 

[http://www.example.com/some/image.png Example '''<del>rich</del>''' ''<ins>link text</ins>'' here.]

which renders as:

Example rich link text here.

If it is enabled on your wiki (see Manual:$wgAllowExternalImages ), you can also embed external images. To do that, simply insert the image's URL: 

http://url.for/some/image.png

Embedded images can be resized by the CSS transform property. They also may be formatted by surrounding MediaWiki markup or HTML/CSS code.

If this wiki option is not enabled, the image will not be embedded but rendered as a textual link to the external site, just like above, unless the site's Manual:$wgAllowExternalImagesFrom has a value.

It is also possible to use InstantCommons (enabled by default) or other shared file repositories to load files from other wikis, which are treated as if they were local images.
