The idea would be to have the following work: var ctx = canvas.getContext('2d'); ctx.filter = "grayscale(0.5)"; // from there on, all rendering calls are conceptually filtered before being composited on the canvas. 60152 1 dino 2011-11-18 20:03:17 +0000 I agree we should do this. I wonder about the modality of the effect though. I don't think you'd want every operation to filter - rather you'd want to set a filter mode, draw a lot of stuff, then apply the filter to the collected content. This is similar to group opacity in SVG and transparency layers in CoreGraphics. 60153 2 smfr 2011-11-18 20:03:58 +0000 If you're using canvas, you can already do filter-like effects via image data. 78052 3 dschulze 2012-11-08 14:53:57 +0000 I don't think this is in the scope of this implementation (Filter Effects). And as Simon said, you can use ImageData already.
