Superimpose another image as click destination
Open, MediumPublicFeature

Description

For maps it would be a great improvement if the imagemap extension can
superimpose another, smaller, image as link destination.

Example for a map with a red dot as superimposed image, followed by the link
destination:

<imagemap>
Image:ExampleMap.JPG|500px|Test map
circ 52 34 5 [[Image:Reddot.svg|5px]] [[Link destination]]
desc none
</imagemap>


Version: unspecified
Severity: enhancement

Not sure how best to accomplish this... CSS positioning? Server-side
composition? SVG?

proposed patch

This patch implements the new "shape" image, and allows relative and negative positions.
With it you could use a line like

image 50% 50% none [[File:Test.png|20px|link=test page|Some description]]

where "image" means to add a superimposing image. "50% 50%" is the base position. "none" is the alignment of the superimposing image (hereby centered). Available are the same positions as for "desc". So top-left means the base position is the upper left position of the superimposing image. bottom-right would be the lower right corner and so on.
The relative positions work for real shapes as well:

rect 10% 10% -10% -10% [[Test]]

would add a rectangle with a margin of 10% in height and width.

There are some new messages I don't have written yet.

minor errors, extended link syntax

I made <imagemap> understand lines like

circle 1 2 3 Test

so {{#tag:imagemap}} could be used for location maps. Normal link don't work, because <imagemap> gets the parsed links and not the plain text.
