Andreik Posted August 28, 2008 Share Posted August 28, 2008 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 When the words fail... music speaks.

Richard Robertson Posted August 28, 2008 Share Posted August 28, 2008 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. Link to comment Share on other sites More sharing options...
Andreik Posted August 28, 2008 Author Share Posted August 28, 2008 I forget this function _ColorGetRed(). This is what I want. Thank Richard Robertson! When the words fail... music speaks. Link to comment Share on other sites More sharing options...
