 440 <h2 class='title'><a name="OVERVIEW">Overview</a></h2>
 441
 442 <p>The CUPS raster API provides a standard interface for reading and writing
 443 CUPS raster streams which are used for printing to raster printers. Because the
 444 raster format is updated from time to time, it is important to use this API to
 445 avoid incompatibilities with newer versions of CUPS.</p>
 446
 447 <p>Two kinds of CUPS filters use the CUPS raster API - raster image processor
 448 (RIP) filters such as <code>pstoraster</code> and <code>cgpdftoraster</code>
 449 (Mac OS X) that produce CUPS raster files and printer driver filters that
 450 convert CUPS raster files into a format usable by the printer. Printer
 451 driver filters are by far the most common.</p>
 452
 453 <p>CUPS raster files (<code>application/vnd.cups-raster</code>) consists of
 454 a stream of raster page descriptions produced by one of the RIP filters such as
 455 <var>pstoraster</var>, <var>imagetoraster</var>, or
 456 <var>cgpdftoraster</var>. CUPS raster files are referred to using the
 457 <a href='#cups_raster_t'><code>cups_raster_t</code></a> type and are
 458 opened using the <a href='#cupsRasterOpen'><code>cupsRasterOpen</code></a>
 459 function. For example, to read raster data from the standard input, open
 460 file descriptor 0:</p>
 461
 462 <pre class="example">
 463 #include &lt;cups/raster.h&gt;>
 464
 465 <a href="#cups_raster_t">cups_raster_t</a> *ras = <a href="#cupsRasterOpen">cupsRasterOpen</a>(0, CUPS_RASTER_READ);
 466 </pre>
 467
 468 <p>Each page of data begins with a page dictionary structure called
 469 <a href="#cups_page_header2_t"><code>cups_page_header2_t</code></a>. This
 470 structure contains the colorspace, bits per color, media size, media type,
 471 hardware resolution, and so forth used for the page.</p>
 472
 473 <blockquote><b>Note:</b>
 474
 475   <p>Do not confuse the colorspace in the page header with the PPD
 476   <tt>ColorModel</tt> keyword. <tt>ColorModel</tt> refers to the general type of
 477   color used for a device (Gray, RGB, CMYK, DeviceN) and is often used to
 478   select a particular colorspace for the page header along with the associate
 479   color profile. The page header colorspace (<tt>cupsColorSpace</tt>) describes
 480   both the type and organization of the color data, for example KCMY (black
 481   first) instead of CMYK and RGBA (RGB + alpha) instead of RGB.</p>
 482
 483 </blockquote>
 484
 485 <p>You read the page header using the
 486 <a href="#cupsRasterReadHeader2"><code>cupsRasterReadHeader2</code></a>
 487 function:</p>
 488
 489 <pre class="example">
 490 #include &lt;cups/raster.h&gt;>
 491
 492 <a href="#cups_raster_t">cups_raster_t</a> *ras = <a href="#cupsRasterOpen">cupsRasterOpen</a>(0, CUPS_RASTER_READ);
 493 <a href="#cups_page_header2_t">cups_page_header2_t</a> header;
 494
 495 while (<a href="#cupsRasterReadHeader2">cupsRasterReadHeader2</a>(ras, &amp;header))
 496 {
 497   /* setup this page */
 498
 499   /* read raster data */
 500
 501   /* finish this page */
 502 }
 503 </pre>
 504
 505 <p>After the page dictionary comes the page data which is a full-resolution,
 506 possibly compressed bitmap representing the page in the printer's output
 507 colorspace. You read uncompressed raster data using the
 508 <a href="#cupsRasterReadPixels"><code>cupsRasterReadPixels</code></a>
 509 function. A <code>for</code> loop is normally used to read the page one line
 510 at a time:</p>
 511
 512 <pre class="example">
 513 #include &lt;cups/raster.h&gt;>
 514
 515 <a href="#cups_raster_t">cups_raster_t</a> *ras = <a href="#cupsRasterOpen">cupsRasterOpen</a>(0, CUPS_RASTER_READ);
 516 <a href="#cups_page_header2_t">cups_page_header2_t</a> header;
 517 int page = 0;
 518 int y;
 519 char *buffer;
 520
 521 while (<a href="#cupsRasterReadHeader2">cupsRasterReadHeader2</a>(ras, &amp;header))
 522 {
 523   /* setup this page */
 524   page ++;
 525   fprintf(stderr, "PAGE: %d %d\n", page, header.NumCopies);
 526
 527   /* allocate memory for 1 line */
 528   buffer = malloc(header.cupsBytesPerLine);
 529

 626 <p class="discussion">This function is used by raster image processing (RIP) filters like
 627 cgpdftoraster and imagetoraster when writing CUPS raster data for a page.
 628 It is not used by raster printer driver filters which only read CUPS
 629 raster data.<br>
 630 <br>
 631
 632 <code>cupsRasterInterpretPPD</code> does not mark the options in the PPD using
 633 the &quot;num_options&quot; and &quot;options&quot; arguments.  Instead, mark the options with
 634 <code>cupsMarkOptions</code> and <code>ppdMarkOption</code> prior to calling it -
 635 this allows for per-page options without manipulating the options array.<br>
 636 <br>
 637 The &quot;func&quot; argument specifies an optional callback function that is
 638 called prior to the computation of the final raster data.  The function
 639 can make changes to the <a href="#cups_page_header2_t"><code>cups_page_header2_t</code></a> data as needed to use a
 640 supported raster format and then returns 0 on success and -1 if the
 641 requested attributes cannot be supported.<br>
 642 <br>
 643
 644 <code>cupsRasterInterpretPPD</code> supports a subset of the PostScript language.
 645 Currently only the <code>[</code>, <code>]</code>, <code><<</code>, <code>>></code>, <code>{</code>,
 646 <code>}</code>, <code>cleartomark</code>, <code>copy</code>, <code>dup</code>, <code>index</code>,
 647 <code>pop</code>, <code>roll</code>, <code>setpagedevice</code>, and <code>stopped</code> operators
 648 are supported.
