Hello, I have to get the width and height size of a bitmap. Do you have an idea of how I could do that? I tried the fonction GetBitmapDimensionEx() but it doesn''t work. I know that the width and height are stored in the bitmap''s header, but how can I access them? Thanks.

Easiest 2 ways I can think of:

1. Load the bitmap with LoadBitmap()/LoadImage() and get information about it with GetObject() (Or another similar function).

2. Open the file yourself and read the header (That''s what you suggested ). Here''s some code for doing that:

// I''m using fopen() to open the file, you can use C++ streams or whatever if you wantFILE *hFile = fopen(<filename>,"rb");BITMAPINFOHEADER info;fseek(hFile,sizeof(BITMAPFILEHEADER),0); // skip the header, it''s uselessfread(&info,sizeof(BITMAPINFOHEADER),1,hFile); // read the info headerfclose(hFile); // close the file again

Now the BITMAPINFOHEADER structure has the info you want.
You can also read the header (Instead of skipping it) to make sure it''s really a bitmap:

BITMAPFILEHEADER fHeader;
// read the header here
if (fHeader.bfType != 0x4D42)
{
// not a bitmap...
}

Yes, read in the info header to find out the dimensions of the bitmap.
