افزونهٔ نقشه تصویر به نقشه‌های تصویری قابلیت کلیک‌کردن را می‌دهد. نقشه تصویر فهرستی از مختصات در یک تصویر خاص است که مناطقی از تصویر را به چندین مقصد پیوند می‌دهد (برخلاف یک پیوند تصویر معمولی، که در آن کل ناحیه تصویر به یک مقصد متصل می‌شود). برای مثال، نقشهٔ جهان ممکن است هر کشور را به اطلاعات بیشتر در مورد آن کشور پیوند دهد. The intention of an image map is to provide an easy way of linking various parts of an image without dividing the image into separate image files.

نمونه‌ها

Simple example without caption

<imagemap>
File:Example2.png|150px|alt=Alt text
default [[Main Page|Go to main page]]
</imagemap>

The above example always links to the Main Page, no matter where you click on it. To find out more about the image, click on the blue "i" icon . An alternative way to create such a linked image, without using this extension would be with [[File:Example2.png|150px|alt=Alt text|title=Go to main page|link=Main Page]]

Complex example with caption

This example display a thumbnail with dimensions (width × height) 500 × 250 pixels; the original image has dimensions 9,600 × 4,800 pixels. The coordinates of each vertex are given in pixels and represent a point on the original image. So for example, the vertices of the polygon surrounding "Jude" (second to the far right in the image) has horizontal-coordinates (measured in pixels from the left) ranging between 7904 – 8635 and vertical-coordinates (measured in pixels from the top) ranging between 2096 – 3260, which are far outside of the range of the displayed 500 × 250 thumbnail but within range of the 9,600 × 4,800 original image. Note that one vertex of the polygon surrounding "Simon" (at the very right of the image), specifically the vertex with coordinate 9625 3301, lies outside of the bounds of the original 9,600 × 4,800 image.

</imagemap>

Image map example. Clicking on a person in the picture causes the browser to load the appropriate article.

The above example links to many different pages, depending on where you click it. To find out more about the image, click on the double-rectangle icon

Syntax description

The contents of an ‎<imagemap> tag consists of blank lines, comments (starting with #) and logical lines.

The first logical line specifies the image to be displayed. This must be in the same format as an ordinary MediaWiki image link (see images help), except without the enclosing [[ and ]] markup.

If the first line specifies a "thumb" or "frame" image, then the first line's caption and any |alt= parameter are treated as the image's caption and alt text in the usual way; otherwise, the first line's |alt= parameter (or, if absent, any caption) specifies the image's alt text.

In neither case does the image itself have title text (often used for tooltips); any title text is taken from the regions described in later lines.

Further lines are split into tokens, separated by whitespace. The function of each line is determined by the first token in the line.

A coordinate consists of two tokens. The first token is the horizontal (X) position and the second token is the vertical (Y) position. All coordinates are according to the full-size image, not the visible image. The X and Y tokens should be specified as distance from left edge (horizontal pixel count) and distance from top (vertical pixel count) of the full-size image.

desc

Specifies the location of a blue "i" icon , which links to the image description. Possible values: top-right, bottom-right (default), bottom-left, top-left, none. This parameter is ignored for "thumb" or "frame" images, which instead employ the usual double-rectangle icon .

poly

A polygon. The coordinates of the vertices are given, followed by a link in square brackets.

rect

A rectangle. The parameters are the coordinates of the top-left and bottom-right corners, followed by a title to link to in square brackets.

Example

<imagemap>
File:PolierMartinWombwellZoffany.jpg|thumb|200px|Colonel Antoine Polier
rect 269 140 344 305 [[Claude Martin]]
rect 124 147 181 298 [[Antoine Polier|Antoine-Louis Polier]]
desc none
</imagemap>

circle

A circle. The first two parameters are the coordinates of the center, the third is the radius. The coordinates are followed by a link in square brackets.

default

This gives the default link, where no other regions are specified.

All coordinates are specified relative to the source image. The image can be scaled using thumbnail syntax, in which case the image map coordinates will be automatically scaled as well.

All links are given in either the form [[Page title]] or [[Page title|description]]. In the latter case, the part after the pipe "|" becomes the title attribute of the link—in most browsers, it will pop up as a tooltip when the user hovers over it; the part after the pipe also becomes the alt text for the link. If no explicit link description is given, the page title is used.

Areas which overlap give precedence to the first link listed.

نصب

This extension is bundled with MediaWiki 1.21 and above. Thus you do not have to download it again.

Make sure that uploads and ImageMagick are installed:

$wgEnableUploads = true;
$wgUseImageMagick = true;
$wgImageMagickConvertCommand = "/usr/bin/convert";

• Download and move the extracted ImageMap folder to your extensions/ directory.
  Developers and code contributors should install the extension from Git instead, using:cd extensions/
git clone https://gerrit.wikimedia.org/r/mediawiki/extensions/ImageMap
• کد زیر را در انتهای $LocalSettings خودتان اضافه کنید:

  wfLoadExtension( 'ImageMap' );
  

•  انجام شد – به Special:Version در ویکی خودتان بروید تا مطئمن شوید که افزونه با موفقیت نصب شده است.

Troubleshooting

1. Check to see if your php DOM is turned on. You may need to install it if it is not.
2. Check whether ImageMagick is installed, since this extension relies on /usr/bin/convert for the resizing. If it is not present, you could get a page with only XML errors (tip: use the back-button in the browser, because you can still edit the page).
3. On OVH mutualized hosting $wgUseImageMagick should be like: $wgUseImageMagick=false;

Composer

You can also install this extension using built-in Composer support.

composer require mediawiki/image-map @dev

Using Composer to install this extension will cause installation of the latest development version of this extension each time you do a "composer update --no-dev" command.

Usage with templates, magic words, or parser functions

If you want this extension (as with most tag extensions) to parse template parameters, magic words, or parser functions, you will need to use #tag syntax, such as w:Template:Click did. In this case the vertical bar | must be replaced by a template {{!}}, where the source text of the template is | (except when they appear inside links or parameters).

Example - standard form:

<imagemap>
File:ExamplePlant80.png|60px|ExamplePlant
rect 0 107 294 260 [[Plants/ExamplePlant|ExamplePlant]]
desc none
</imagemap>

Example - with variable {{PAGENAME}}

{{#tag:imagemap|
File:ExamplePlant80.png{{!}}60px{{!}}ExamplePlant
rect 0 107 294 260 [[{{PAGENAME}}/ExamplePlant|ExamplePlant]]
desc none
}}

Example – Modified to accept an input parameter to control image size:

These modifications allow the template size to be adjusted on the edited (target) page and eliminate the need to create duplicate templates of various image sizes.

{{#tag:imagemap|
Image:Examplename.jpg {{!}}{{{1|640px}}}
rect 0 107 294 260
circle 360 114 70
poly 357 216 363 417 211
desc none
}}

Where {{{1|640px}}} is the input parameter “1” and a default image size of 640px.

Note: the input parameter requires a text string ending with “px” to function properly.

For example, calling a template {{TemplateName|400px}} will display the template at 400 pixels.

To convert the standard (existing) image maps to this optional format:

• Replace the initial ‎<imagemap> with {{#tag:imagemap|
• Add {{!}}{{{1|640px}}} after the image name (change the default image size to match the currently existing size).

Note: By changing the default size (640px in this example) to the current image size, none of the existing template calls will have to be modified and will display correctly. Existing template calls can still be modified later by using the input parameter.

• Replace the final ‎</imagemap> with }} (the trailing braces).
