NAMEPS_open_image_file — Opens an image from file
SYNOPSIS
#include <pslib.h>
int PS_open_image_file(PSDoc *psdoc, const char *type, const char
*filename, const char *stringparam, int intparam)
DESCRIPTION
This function reads image data from a file. It can read png, jpeg,
gif, tiff, and eps files. png, jpeg, gif, and tiff images
can only be read if pslib has been compiled with support
for those formats. Once an image has been loaded it can
be placed on a page with PS_place_image(3).
Since version 0.4.5 of pslib images are read by default for later
reuse. This means that the image is saved into a so
called reusable stream object. Later calls of
PS_place_image(3) will only put a short
sequence of postscript code into the output file replay‐
ing the image. This reduces the overall postscript file
size, speeds up its processing by the postscript rip and
allows to place images into templates. This behaviour
can be turned off by setting the parameter `imagereuse'
to false with PS_set_parameter(3).
RETURN VALUE
Returns identifier of image or zero in case of an error.
The identifier is a positiv number greater 0.
