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 ordering 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.
