crop_sprite()

QPixmap* crop_sprite	(	const QPixmap *	source,
		int	x,
		int	y,
		int	width,
		int	height,
		const QPixmap *	mask,
		int	mask_offset_x,
		int	mask_offset_y
	)

Create a new sprite by cropping and taking only the given portion of the image.

source gives the sprite that is to be cropped.

x,y, width, height gives the rectangle to be cropped. The pixel at position of the source sprite will be at (0,0) in the new sprite, and the new sprite will have dimensions (width, height).

mask gives an additional mask to be used for clipping the new sprite. Only the transparency value of the mask is used in crop_sprite. The formula is: dest_trans = src_trans * mask_trans. Note that because the transparency is expressed as an integer it is common to divide it by 256 afterwards.

mask_offset_x, mask_offset_y is the offset of the mask relative to the origin of the source image. The pixel at (mask_offset_x,mask_offset_y) in the mask image will be used to clip pixel (0,0) in the source image which is pixel (-x,-y) in the new image.
