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 *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 replaying 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.
