int( * image_type::probe) (struct image *image)

Probe image.

Parameters

image

Image

Return values

rc	Return status code

Return success if the image is of this image type.

Definition at line 105 of file image.h.

exec

int( * image_type::exec) (struct image *image)

Parameters

image

Image

Return values

rc	Return status code

Parameters

image	Image
pixbuf	Pixel buffer to fill in

Return values

rc	Return status code
