RE : GooCanvas : Clipboard copy

Hey,

I have found the solution !!! The problem is in the
convert_color_channel() function.

The original code is :

guchar convert_color_channel(guchar src, guchar alpha)
{
	return alpha ? ((src << 8) - src) / alpha : 0;
}

And the "GOOD" code is :

guchar convert_color_channel(guchar src, guchar alpha)
{
	return alpha ? ((src << 8) - src) / alpha : 255;
}

Thank you for your help Damon,

Cyril
