PS_BEGIN_TEMPLATE(3)					     Library Functions Manual					      PS_BEGIN_TEMPLATE(3)

NAME

       PS_begin_template -- Starts a new template

SYNOPSIS

       #include <pslib.h>

       int PS_begin_template(PSDoc *psdoc, float width, float height)

DESCRIPTION

       Starts a new template which must be ended by PS_end_template(3). Templates are similar to macros which can be placed on a page like images.
       Within a template one can call any drawing function. Once a template has been ended by PS_end_template(3) it can be placed  on  a  page	by
       PS_place_image(3). Templates are commonly used for repeating objects like page headers in order to minimize the document size.

       If  image  reuse  is not turned off (since version 0.4.5 of pslib it is always turned on), PS_place_image(3)		may also be called
       within a template in order to include eps or raster images.

RETURN VALUE

       Returns an id for referencing the template.

NAME

       PS_open_image -- Reads an image for later placement

SYNOPSIS

       #include <pslib.h>

       int  PS_open_image(PSDoc  *psdoc,  char	*type, char *source, char *data, int lenght, int width, int height, int components, int bpc, const
       char *params)

DESCRIPTION

       Reads an image which is already available in memory. The parameter source is currently not evaluated and assumed to be `memory'. The param-
       eter type can be either `raw' or `eps'. Images in raw format are expected to be a stream of pixels starting in the upper left and ending in
       the lower right corner. Each pixel is a tuple of components representing the colors. Each component  consists  of  bpc  bit.  Color  imgags
       expect  the  components to be stored in RGB or CMYK order. The number of components implies the colorspace. 4 components imply a CMYK image
       and not an RGB image with an alpha channel. This restriction may be removed in later versions.

       EPS images are expect as stored in a file. There is no need to set any other paramter. The height und width of the image is taken from  the
       bounding box within the image data.

       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 the image or zero in case of an error.  The identifier is a positiv number greater 0.
