You mean, like

ChromaKey_hsv_combineChannelShader.data.outputColor0UseInputColor.value[0] = 1;
ChromaKey_hsv_combineChannelShader.data.outputColor1.value[0] = 1.0;
ChromaKey_hsv_combineChannelShader.data.outputColor1.value[1] = 1.0;
ChromaKey_hsv_combineChannelShader.data.outputColor1.value[2] = 1.0;
ChromaKey_hsv_combineChannelShader.data.outputColor1.value[3] = 0.0;

I can’t seem to make it work. I’m trying to make a button show behind the chroma like this:

mx:Canvas blendMode=”layer”
mx:Button label=”my button”/
mx:Image source=”@Embed(‘colors.png’)” blendMode=”alpha”/
/mx:Canvas

What could be wrong?

You can set one of them as true and set the other outputColor as transparent, finally put another image at the bottom of the filtered image. @Juan
If look into the source of the kernel, there are “outputColor0UseInputColor” and “outputColor1UseInputColor” params.

You can set one of them as true and set the other outputColor as transparent, finally put another image at the bottom of the filtered image.

For flex 4 must change tabNav.selectedChild; to Container(tabNav.selectedChild); What should be done to get a color image instead of a b/w mask? Got it. For flex 4 must change

tabNav.selectedChild;

to

Container(tabNav.selectedChild);

What should be done to get a color image instead of a b/w mask?

I tried to export it for Flash with version 1.0.352475 ( included with CS4 ) and the filter gave a strange output ( not in the pixel bender environment itself ). With version 1.5 the filter works correctly in Flash as well. Make sure if you want to use this filter in Flash to install a new version ( 1.5 ) of PixelBender.
