NAME
im_raw2vips, im_vips2raw - wrap a raw binary file inside an IMAGE
descriptor
SYNOPSIS
#include <vips/vips.h>
int
im_raw2vips( const char *filename, IMAGE *out,
int width, int height, int bpp, int offset )
int
im_vips2raw( IMAGE *in, int fd )
DESCRIPTION
im_raw2vips(3) mmaps the file named, setting image out so that access
to that image will read from the file. The parameters specify the
image width, height, bytes per pixel and offset in bytes from the start
of the file.
Use functions like im_copy_morph(3) to set the pixel type, byte order-
ing and so on.
im_vips2raw(3) writes the pixels in the IMAGE to the file descriptor.
It's handy for writing writers for other formats.
RETURN VALUE
The functions return NULL on error.
