PS_OPEN_IMAGE_FILE(3)					     Library Functions Manual					     PS_OPEN_IMAGE_FILE(3)

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  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.
