GDI+ problem

[Andreik]

I have a picture (.BMP) that have 3x3 pixel (a very small picture).

First line is like this: 0xFF0000;0x7F00FF;0x0000FF

Second line is 0x400000;0xFFFFFF;0x7F0000

Last line is 0x0100FF;0xFF0000;0x0000FF

I want to read red value from this picture and to create another picture with values of red:

0xFF0000;0x7F0000;0x000000

0x400000;0xFF0000;0x7F0000

0x010000;0xFF0000;0x000000

What method are you using to read and write? Where are you having trouble?

You just need to read the integer value, and then BitAnd it with 0xFF0000 then put it in the new picture.

I forget this function _ColorGetRed(). This is what I want. Thank Richard Robertson!
