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.

ps_open_image - Reads an image for later placement

SYNOPSIS

       int  ps_open_image  (resource  $psdoc, string  $type, string  $source, string  $data, int  $lenght, int	$width, int  $height, int  $compo-
       nents, int  $bpc, string  $params)

DESCRIPTION

	Reads an image which is already available in memory. The parameter $source is currently not evaluated and assumed to be memory. The  image
       data  is  a  sequence  of  pixels starting in th upper left corner and ending in the lower right corner. Each pixel consists of $components
       color components, and each component has $bpc bits.

PARAMETERS

	      o $psdoc
		- Resource identifier of the postscript file as returned by ps_new(3).

	      o $type
		- The type of the image. Possible values are png, jpeg, or eps.

	      o $source
		- Not used.

	      o $data
		- The image data.

	      o $length
		- The length of the image data.

	      o $width
		- The width of the image.

	      o $height
		- The height of the image.

	      o $components
		- The number of components for each pixel. This can be 1 (gray scale images), 3 (rgb images), or 4 (cmyk, rgba images).

	      o $bpc
		- Number of bits per component (quite often 8).

	      o $params
		-

RETURN VALUES

	Returns identifier of image or zero in case of an error. The identifier is a positive number greater than 0.
