Hi all,
I am new to C++, here are some questions about 24bit bitmap, please help!
Can anyone tell me how can I access the RGB value of any coordinates in the raw
data with the pointer ptr?
BYTE * ptr =(BYTE *)IMAGEDATA(lpBi);

any advise or reference are appreciated! thanks!

What is IMAGEDATA and what is lpBi?
How did you load the bitmap?
