I think, it is more simpler to use a range value as float which determine the distance between the target color to remove (and other color in a circle of radius equal to that range). There is many way to make a chroma_key... But you are right, the aim of this abstractions is to be like pix_ object (when it is possible). What other people think about it ?<br>
</p>
<p dir="ltr">I think it's better to have drop-in replacement of pix_* object, but it could be difficult to manage<br>
for example a strict equivalent to pix_chroma_key should handle a no argument initialisation, is this possible with glsl_chroma_key ?<br>

<p dir="ltr">yes and pix_chroma_key doesn't handle non equal texture, so this is good but, I think we can make it more silently<br>
By scaling texcoord according to texture size<br>
But maybe i m wrong...<br>
