Create Drawings, or add notes to Images

create or annotate images and save as svg and png


WikiDrawPlugin uses SVG-edit (trunk svn from 29/09/2010 - pre2.6) to provide quick and easy drawing or annotation of images.

WARNING: editing not compatible with InternetExplorer - but viewing of the drawings works correctly

Syntax Rules

Warning: Can't find topic System.VarWIKIDRAW

save drawing as attachment to current topic


save drawing to a 'WikiDrawForm' topic

WikiDraw also can save the svg source for the drawing as the text of a topic - allowing searching and hand editing of that source, while continuing to provide the wysiwyg editing facility.


Extra Plugin support.

If Foswiki:Extensions.ImagePlugin is installed and enabled, the default skin template will automatically use it to lay out the image and drawing.

Technical details

This plugin adds a ext-foswiki.js extension that over-rides the built in 'Save Image' SVG menu item with a save to foswiki handler, which generates a png version of the overlay, and sends that, and the svg source to foswiki.

The transparent overlay png is displayed in view mode, and the annotated image (if any) will be put behind it using the css background.

Known issues:

  1. it really doesn't like using svg dimensions other than 640x480 (I'e reported an issue for this, as its really painful when creating a drawing)
  2. hide the edit buttons for ie..
  3. _DEFAULT="Web.Topic/something" is very broken
  4. strikeone support
  5. comment support..
  6. wow. subtle bug. - using %!WIKIDRAW{Sandbox.SomeTopic}%, will find the first image attached to BASETOPIC, which might be a tad surprising.

features to be added?

  1. can we diff the svg's ?
