<h2 class='title'><a name="OVERVIEW">Overview</a></h2>
|
||
|
||
<p>The CUPS raster API provides a standard interface for reading and writing
|
||
CUPS raster streams which are used for printing to raster printers. Because the
|
||
raster format is updated from time to time, it is important to use this API to
|
||
avoid incompatibilities with newer versions of CUPS.</p>
|
||
|
||
<p>Two kinds of CUPS filters use the CUPS raster API - raster image processor
|
||
(RIP) filters such as <code>pstoraster</code> and <code>cgpdftoraster</code>
|
||
(macOS) that produce CUPS raster files and printer driver filters that
|
||
convert CUPS raster files into a format usable by the printer. Printer
|
||
driver filters are by far the most common.</p>
|
||
|
||
<p>CUPS raster files (<code>application/vnd.cups-raster</code>) consists of
|
||
a stream of raster page descriptions produced by one of the RIP filters such as
|
||
<var>pstoraster</var>, <var>imagetoraster</var>, or
|
||
<var>cgpdftoraster</var>. CUPS raster files are referred to using the
|
||
<a href='#cups_raster_t'><code>cups_raster_t</code></a> type and are
|
||
opened using the <a href='#cupsRasterOpen'><code>cupsRasterOpen</code></a>
|
||
function. For example, to read raster data from the standard input, open
|
||
file descriptor 0:</p>
|
||
|
||
<pre class="example">
|
||
#include <cups/raster.h>
|
||
|
||
<a href="#cups_raster_t">cups_raster_t</a> *ras = <a href="#cupsRasterOpen">cupsRasterOpen</a>(0, CUPS_RASTER_READ);
|
||
</pre>
|
||
|
||
<p>Each page of data begins with a page dictionary structure called
|
||
<a href="#cups_page_header2_t"><code>cups_page_header2_t</code></a>. This
|
||
structure contains the colorspace, bits per color, media size, media type,
|
||
hardware resolution, and so forth used for the page.</p>
|
||
|
||
<blockquote><b>Note:</b>
|
||
|
||
<p>Do not confuse the colorspace in the page header with the PPD
|
||
<tt>ColorModel</tt> keyword. <tt>ColorModel</tt> refers to the general type of
|
||
color used for a device (Gray, RGB, CMYK, DeviceN) and is often used to
|
||
select a particular colorspace for the page header along with the associate
|
||
color profile. The page header colorspace (<tt>cupsColorSpace</tt>) describes
|
||
both the type and organization of the color data, for example KCMY (black
|
||
first) instead of CMYK and RGBA (RGB + alpha) instead of RGB.</p>
|
||
|
||
</blockquote>
|
||
|
||
<p>You read the page header using the
|
||
<a href="#cupsRasterReadHeader2"><code>cupsRasterReadHeader2</code></a>
|
||
function:</p>
|
||
|
||
<pre class="example">
|
||
#include <cups/raster.h>
|
||
|
||
<a href="#cups_raster_t">cups_raster_t</a> *ras = <a href="#cupsRasterOpen">cupsRasterOpen</a>(0, CUPS_RASTER_READ);
|
||
<a href="#cups_page_header2_t">cups_page_header2_t</a> header;
|
||
|
||
while (<a href="#cupsRasterReadHeader2">cupsRasterReadHeader2</a>(ras, &header))
|
||
{
|
||
/* setup this page */
|
||
|
||
/* read raster data */
|
||
|
||
/* finish this page */
|
||
}
|
||
</pre>
|
||
|
||
<p>After the page dictionary comes the page data which is a full-resolution,
|
||
possibly compressed bitmap representing the page in the printer's output
|
||
colorspace. You read uncompressed raster data using the
|
||
<a href="#cupsRasterReadPixels"><code>cupsRasterReadPixels</code></a>
|
||
function. A <code>for</code> loop is normally used to read the page one line
|
||
at a time:</p>
|
||
|
||
<pre class="example">
|
||
#include <cups/raster.h>
|
||
|
||
<a href="#cups_raster_t">cups_raster_t</a> *ras = <a href="#cupsRasterOpen">cupsRasterOpen</a>(0, CUPS_RASTER_READ);
|
||
<a href="#cups_page_header2_t">cups_page_header2_t</a> header;
|
||
int page = 0;
|
||
int y;
|
||
char *buffer;
|
||
|
||
while (<a href="#cupsRasterReadHeader2">cupsRasterReadHeader2</a>(ras, &header))
|
||
{
|
||
/* setup this page */
|
||
page ++;
|
||
fprintf(stderr, "PAGE: %d %d\n", page, header.NumCopies);
|
||
|
||
/* allocate memory for 1 line */
|
||
buffer = malloc(header.cupsBytesPerLine);
|
||
|
||
/* read raster data */
|
||
for (y = 0; y < header.cupsHeight; y ++)
|
||
{
|
||
if (<a href="#cupsRasterReadPixels">cupsRasterReadPixels</a>(ras, buffer, header.cupsBytesPerLine) == 0)
|
||
break;
|
||
|
||
/* write raster data to printer on stdout */
|
||
}
|
||
|
||
/* finish this page */
|
||
}
|
||
</pre>
|
||
|
||
<p>When you are done reading the raster data, call the
|
||
<a href="#cupsRasterClose"><code>cupsRasterClose</code></a> function to free
|
||
the memory used to read the raster file:</p>
|
||
|

<pre class="example">
