><a name=
"OVERVIEW">Overview
</a></h2>
453 <p>The CUPS raster API provides a standard interface for reading and writing
454 CUPS raster streams which are used for printing to raster printers. Because the
455 raster format is updated from time to time, it is important to use this API to
456 avoid incompatibilities with newer versions of CUPS.
</p>
458 <p>Two kinds of CUPS filters use the CUPS raster API - raster image processor
459 (RIP) filters such as
<code>pstoraster
</code> and
<code>cgpdftoraster
</code>
460 (Mac OS X) that produce CUPS raster files and printer driver filters that
461 convert CUPS raster files into a format usable by the printer. Printer
462 driver filters are by far the most common.
</p>
464 <p>CUPS raster files (
<code>application/vnd.cups-raster
</code>) consists of
465 a stream of raster page descriptions produced by one of the RIP filters such as
466 <var>pstoraster
</var>,
<var>imagetoraster
</var>, or
467 <var>cgpdftoraster
</var>. CUPS raster files are referred to using the
468 <a href='#cups_raster_t'
><code>cups_raster_t
</code></a> type and are
469 opened using the
<a href='#cupsRasterOpen'
><code>cupsRasterOpen
</code></a>
470 function. For example, to read raster data from the standard input, open
471 file descriptor
0:
</p>
473 <pre class=
"example">
474 #include
<cups/raster.h
>>
476 <a href=
"#cups_raster_t">cups_raster_t
</a> *ras =
<a href=
"#cupsRasterOpen">cupsRasterOpen
</a>(
0, CUPS_RASTER_READ);
479 <p>Each page of data begins with a page dictionary structure called
480 <a href=
"#cups_page_header2_t"><code>cups_page_header2_t
</code></a>. This
481 structure contains the colorspace, bits per color, media size, media type,
482 hardware resolution, and so forth used for the page.
</p>
484 <blockquote><b>Note:
</b>
486 <p>Do not confuse the colorspace in the page header with the PPD
487 <tt>ColorModel
</tt> keyword.
<tt>ColorModel
</tt> refers to the general type of
488 color used for a device (Gray, RGB, CMYK, DeviceN) and is often used to
489 select a particular colorspace for the page header along with the associate
490 color profile. The page header colorspace (
<tt>cupsColorSpace
</tt>) describes
491 both the type and organization of the color data, for example KCMY (black
492 first) instead of CMYK and RGBA (RGB + alpha) instead of RGB.
</p>
496 <p>You read the page header using the
497 <a href=
"#cupsRasterReadHeader2"><code>cupsRasterReadHeader2
</code></a>
500 <pre class=
"example">
501 #include
<cups/raster.h
>>
503 <a href=
"#cups_raster_t">cups_raster_t
</a> *ras =
<a href=
"#cupsRasterOpen">cupsRasterOpen
</a>(
0, CUPS_RASTER_READ);
504 <a href=
"#cups_page_header2_t">cups_page_header2_t
</a> header;
506 while (
<a href=
"#cupsRasterReadHeader2">cupsRasterReadHeader2
</a>(ras,
&header))
508 /* setup this page */
510 /* read raster data */
512 /* finish this page */
516 <p>After the page dictionary comes the page data which is a full-resolution,
517 possibly compressed bitmap representing the page in the printer's output
518 colorspace. You read uncompressed raster data using the
519 <a href=
"#cupsRasterReadPixels"><code>cupsRasterReadPixels
</code></a>
520 function. A
<code>for
</code> loop is normally used to read the page one line
523 <pre class=
"example">
524 #include
<cups/raster.h
>>
526 <a href=
"#cups_raster_t">cups_raster_t
</a> *ras =
<a href=
"#cupsRasterOpen">cupsRasterOpen
</a>(
0, CUPS_RASTER_READ);
527 <a href=
"#cups_page_header2_t">cups_page_header2_t
</a> header;
532 while (
<a href=
"#cupsRasterReadHeader2">cupsRasterReadHeader2
</a>(ras,
&header))
534 /* setup this page */
536 fprintf(stderr,
"PAGE: %d %d\n", page, header.NumCopies);
538 /* allocate memory for
1 line */
539 buffer = malloc(header.cupsBytesPerLine);
541 /* read raster data */
542 for (y =
0; y
< header.cupsHeight; y ++)
544 if (
<a href=
"#cupsRasterReadPixels">cupsRasterReadPixels
</a>(ras, buffer, header.cupsBytesPerLine) ==
0)
547 /* write raster data to printer on stdout */
550 /* finish this page */
554 <p>When you are done reading the raster data, call the
555 <a href=
"#cupsRasterClose"><code>cupsRasterClose
</code></a> function to free
556 the memory used to read the raster file:
