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