Hi Rohit<br>
<br>
I suspect the issue is how you are replacing the pixel. I'm no expert
in this but some of the painting / drawing routines do XORs etc of the
new and old colour depending on the API and parmters set. I would
check there first.<br>
<br>
Hope that is some help.<br>
<br>
Cheers<br>
Rob<br>

I am a little puzzled. I know that the system colours such as
clBtnFace are special constants. In one part of the app, when I
replace a pixel in a bitmap to clBtnFace it goes gray like it should.
In another part of the app it goes money-greeny. Both do it
consustently.<br>
<br>
Any clues ? Do I need to convert these special colours to real colours
? I couldn't find any function to do it.<br>
