Display the next frame of sprite GDI

Question

I've a sprite which contains a lot of images. I see the BitBlt only display the position and imageWidth and imageHeight.

If I want to display a bitmap but only from Width[24] to Width[48] not from the beginning of that bitmap

Thanks for reading this :)

Answer 1

Here is the BitBlt signature:

BOOL BitBlt(
  __in  HDC hdcDest,
  __in  int nXDest,
  __in  int nYDest,
  __in  int nWidth,
  __in  int nHeight,
  __in  HDC hdcSrc,
  __in  int nXSrc,
  __in  int nYSrc,
  __in  DWORD dwRop
);

To copy only part of the source onto your destination DC, you would use nXSrc = 24 and nWidth = 24 (to match your example of copying from columns 24 through 48).
