This function adds an image or images to an image list, generating a mask from the specified bitmap.

  COLORREF crMask 
);

Parameters

  • himl
    [in] Handle to the image list.
  • hbmImage
    [in] Handle to the bitmap that contains one or more images. The number of images is inferred from the width of the bitmap.
