 461 <h2 class='title'><a name="OVERVIEW">Overview</a></h2>
 462
 463 <p>The CUPS raster API provides a standard interface for reading and writing
 464 CUPS raster streams which are used for printing to raster printers. Because the
 465 raster format is updated from time to time, it is important to use this API to
 466 avoid incompatibilities with newer versions of CUPS.</p>
 467
 468 <p>Two kinds of CUPS filters use the CUPS raster API - raster image processor
 469 (RIP) filters such as <code>pstoraster</code> and <code>cgpdftoraster</code>
 470 (macOS) that produce CUPS raster files and printer driver filters that
 471 convert CUPS raster files into a format usable by the printer. Printer
 472 driver filters are by far the most common.</p>
 473
 474 <p>CUPS raster files (<code>application/vnd.cups-raster</code>) consists of
 475 a stream of raster page descriptions produced by one of the RIP filters such as
 476 <var>pstoraster</var>, <var>imagetoraster</var>, or
 477 <var>cgpdftoraster</var>. CUPS raster files are referred to using the
 478 <a href='#cups_raster_t'><code>cups_raster_t</code></a> type and are
 479 opened using the <a href='#cupsRasterOpen'><code>cupsRasterOpen</code></a>
 480 function. For example, to read raster data from the standard input, open
 481 file descriptor 0:</p>
 482
 483 <pre class="example">
 484 #include &lt;cups/raster.h&gt;
 485
 486 <a href="#cups_raster_t">cups_raster_t</a> *ras = <a href="#cupsRasterOpen">cupsRasterOpen</a>(0, CUPS_RASTER_READ);
 487 </pre>
 488
 489 <p>Each page of data begins with a page dictionary structure called
 490 <a href="#cups_page_header2_t"><code>cups_page_header2_t</code></a>. This
 491 structure contains the colorspace, bits per color, media size, media type,
 492 hardware resolution, and so forth used for the page.</p>
 493
 494 <blockquote><b>Note:</b>
 495
 496   <p>Do not confuse the colorspace in the page header with the PPD
 497   <tt>ColorModel</tt> keyword. <tt>ColorModel</tt> refers to the general type of
 498   color used for a device (Gray, RGB, CMYK, DeviceN) and is often used to
 499   select a particular colorspace for the page header along with the associate
 500   color profile. The page header colorspace (<tt>cupsColorSpace</tt>) describes
 501   both the type and organization of the color data, for example KCMY (black
 502   first) instead of CMYK and RGBA (RGB + alpha) instead of RGB.</p>
 503
 504 </blockquote>
 505
 506 <p>You read the page header using the
 507 <a href="#cupsRasterReadHeader2"><code>cupsRasterReadHeader2</code></a>
 508 function:</p>
 509
 510 <pre class="example">
 511 #include &lt;cups/raster.h&gt;
 512
 513 <a href="#cups_raster_t">cups_raster_t</a> *ras = <a href="#cupsRasterOpen">cupsRasterOpen</a>(0, CUPS_RASTER_READ);
 514 <a href="#cups_page_header2_t">cups_page_header2_t</a> header;
 515
 516 while (<a href="#cupsRasterReadHeader2">cupsRasterReadHeader2</a>(ras, &amp;header))
 517 {
 518   /* setup this page */
 519
 520   /* read raster data */
 521
 522   /* finish this page */
 523 }
 524 </pre>
 525
 526 <p>After the page dictionary comes the page data which is a full-resolution,
 527 possibly compressed bitmap representing the page in the printer's output

 697 <code>cupsRasterInterpretPPD</code> does not mark the options in the PPD using

 700 this allows for per-page options without manipulating the options array.<br>

 702 The &quot;func&quot; argument specifies an optional callback function that is
 703 called prior to the computation of the final raster data.  The function
 704 can make changes to the <a href="#cups_page_header2_t"><code>cups_page_header2_t</code></a> data as needed to use a
 705 supported raster format and then returns 0 on success and -1 if the
