NAME
PS_open_image_file -- Opens an image from file
SYNOPSIS
#include <pslib.h>
int PS_open_image_file(PSDoc *psdoc, const char *type, const char *file-
name, 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 replaying the image. This reduces
the overall postscript file size, speeds up its processing by
the postscript rip and allows to place images into tem-
plates. This behaviour can be turned off by setting the pa-
rameter `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.
