Hi, With the increasing speed of javascript engines, some other performance issues are starting to become apparent. Take this demo for example: http://playground.q42.nl/animatie/blobs/sjoerd/blobscolor.html A large percentage of the time goes into building color strings for setting the strokeStyle, which the browser then has to take apart again. This is a very unnecessary performance hit. (Btw, on my Mac this runs faster under Google Chrome in VMware than natively in the latest Webkit nightly.) I think the canvas api should get 2 new methods: CanvasColor createRGBAColor(in float r, in float g, in float b, in float a) CanvasColor createHSLAColor(in float h, in float s, in float l, in float a) CanvasColor objects could be opaque, or maybe they have a toString method that returns the CSS serialization. The strokeStyle, fillStyle and shadowColor attributes should accept these objects, and probably the addColorStop method as well. Using CSS color strings should still work obviously. On getting these attributes the serialization must still be returned like it is now. greetings, -- Sjoerd Visscher sjoerd at w3future.com
