HtmlCanvas shape need intersectsStroke and intersectsBounds, - and intersects (region). -2) SVG and VML are "live" scene graphs; eg. any state change to objects in the - scene automatically get rendered in next engine render pass. For canvas, it's - procedural, and current implementation requires application to call surface.render() - whenever scene needs to be updated. Plan is to do dirty region checking based - on bounding boxes (currently not properly computed), and track dirty areas anytime - state changes (invalidate) separate from render phase. - Add the following call where changes to the scene graph are complete and you want to - render: - - if (surface.render){surface.render();} - -4) Text/Text Paths - Text shape is implemented using DIV overlays. Many text styles are not - applied, and outline/fills are not possible. This is due to limitations in Canvas spec. - Firefox 3.0 has proprietary text functions that we could test for and use once FF3 is out. - No luck on Safari. -3) No Image skewing - Limitation of Canvas - -Known Bugs: -1) Matrix xformations (applied from root to shape leaf nodes) not quite right--but very close. - Canvas does not have a built in transformation function that allows skewing. Need to - track skew matrix with Shape, and perform other trans/rot/scale transformations without - using canvas transform functions. - - -------------------------------------------------------------------------------- -Installation instructions - -Grab the following from the Dojo SVN Repository: -http://svn.dojotoolkit.org/var/src/dojo/dojox/trunk/gfx.js -http://svn.dojotoolkit.org/var/src/dojo/dojox/trunk/gfx/* - -Install into the following directory structure: -/dojox/gfx/ - -...which should be at the same level as your Dojo checkout. -------------------------------------------------------------------------------- -- cgit v1.2.3-54-g00ecf
