Convert to Integer in Python


def readBMP( filename):
    f = file( filename)
    content = f.read()
    f.close()
    return content
   
def getDimensions( bytes):
    return bytes[18:22],bytes[22:26]

w,h = getDimensions( getBMP( 'test.bmp'))

how do i convert w and h to int?
atm (w,h) == ('\x05\x00\x00\x00', '\x05\x00\x00\x00')

This is the sort of thing that happens when you try to use a scripting language oriented towards text processing for binary data.

struct {
 int a;
 int b;
} d;
...
 fread(&d, 1, sizeof(d), pfile);
 ...
 ... d.a ...
 ... d.b ...

Or if you don't care for defining structures/the offsets aren't fixed just use *(your_desired_type)(ptr + byte_offs) to pick out the pieces directly.
