[Moved] Filter an image with an qRGB component.

[bensha]

Hi Guys,

I would like to filter an image (QImage myImage) with a color (QRgb myColor).
The purpose is to obtain a new image with black and white pixels.
Black pixels should match with myColor pixels of myImage.

for example, if I have a blue cup on myImage and I filter with a blue component, I want to obtain the black shape of my cup in myNewImage.

Which function can I use for doing that?

I tried to use createMaskFromColor function and apply it to my image, but I didn't succeed.
My code :
@myNewImage=myImage.createMaskFromColor(color, Qt::MaskOutColor);@

Cheers mates!
