Sure thing, see attachment (screencapture). I'd still recommend installing Opera 10 for future comparisons, http://my.opera.com/desktopteam for the latest releases. Couldn't get the Adobe plugin to cooperate unfortunately, maybe I need a reboot.
Thanks! Seems like it also does not support the bias property though...
Here's what Opera 10 does wrt to @bias (it is applied):
- After applying the @kernelMatrix and @divisor the number in @bias will be added to each channel - If @preserveAlpha is "true" then the alphachannel will not get any bias added.
It's agreed that this is probably not what one wants. Considering that @bias is probably not that widely used at the moment we should try to make it clear in the spec and to make the bias useful.
How about changing the spec to say something like the following for the application of @bias:
[[ To apply bias on a pixel follow these steps: 1. For each color channel (RGB) let the 'actual bias value' be the bias value multiplied by (ResultAlpha(X,Y)-bias). After applying the kernelMatrix and divisor, add the 'actual bias value' to each component (RGB). 2. For the alpha channel, unless preserveAlpha is 'true', add the [unmodified] bias value. ]]
