Did you read the documentation [^]?

for instance the following section of BITMAPINFO struct documentation looks promising:

A DIB consists of two distinct parts: a BITMAPINFO structure describing the dimensions and colors of the bitmap, and an array of bytes defining the pixels of the bitmap. The bits in the array are packed together, but each scan line must be padded with zeroes to end on a LONG data-type boundary. If the height of the bitmap is positive, the bitmap is a bottom-up DIB and its origin is the lower-left corner. If the height is negative, the bitmap is a top-down DIB and its origin is the upper left corner.

Solution 4

Dear,

I wish this could be the answer of your question.

MIDL

System.Drawing.Bitmap b = new Bitmap(Image.FromFile("@C:\abc.jpg"));
b.GetPixel(0, 0).R ;
b.GetPixel(0, 0).G;
b.GetPixel(0, 0).B;

Thanks

Solution 1

Can you provide more information? There are many things that you could mean when you say "bitmap".
