364 | <h2 class='title'><a name="OVERVIEW">Overview</a></h2> |
365 | ||
366 | <p>The CUPS raster API provides a standard interface for reading and writing | |
367 | CUPS raster streams which are used for printing to raster printers. Because the | |
368 | raster format is updated from time to time, it is important to use this API to | |
369 | avoid incompatibilities with newer versions of CUPS.</p> | |
370 | ||
79e1d494 MS |
371 | <p>Two kinds of CUPS filters use the CUPS raster API - raster image processor |
372 | (RIP) filters such as <code>pstoraster</code> and <code>cgpdftoraster</code> | |
373 | (Mac OS X) that produce CUPS raster files and printer driver filters that | |
374 | convert CUPS raster files into a format usable by the printer. Printer | |
375 | driver filters are by far the most common.</p> | |
376 | ||
5a738aea MS |
377 | <p>CUPS raster files (<code>application/vnd.cups-raster</code>) consists of |
378 | a stream of raster page descriptions produced by one of the RIP filters such as | |
379 | <var>pstoraster</var>, <var>imagetoraster</var>, or | |
380 | <var>cgpdftoraster</var>. CUPS raster files are referred to using the | |
381 | <a href='#cups_raster_t'><code>cups_raster_t</code></a> type and are | |
382 | opened using the <a href='#cupsRasterOpen'><code>cupsRasterOpen</code></a> | |
383 | function. For example, to read raster data from the standard input, open | |
384 | file descriptor 0:</p> | |
385 | ||
386 | <pre class="example"> | |
387 | #include <cups/raster.h>> | |
388 | ||
389 | <a href="#cups_raster_t">cups_raster_t</a> *ras = <a href="#cupsRasterOpen">cupsRasterOpen</a>(0, CUPS_RASTER_READ); | |
390 | </pre> | |
b423cd4c | 391 | |
5a738aea MS |
392 | <p>Each page of data begins with a page dictionary structure called |
393 | <a href="#cups_page_header2_t"><code>cups_page_header2_t</code></a>. This | |
394 | structure contains the colorspace, bits per color, media size, media type, | |
79e1d494 MS |
395 | hardware resolution, and so forth used for the page.</p> |
396 | ||
397 | <blockquote><b>Note:</b> | |
398 | ||
399 | <p>Do not confuse the colorspace in the page header with the PPD | |
400 | <tt>ColorModel</tt> keyword. <tt>ColorModel</tt> refers to the general type of | |
401 | color used for a device (Gray, RGB, CMYK, DeviceN) and is often used to | |
402 | select a particular colorspace for the page header along with the associate | |
403 | color profile. The page header colorspace (<tt>cupsColorSpace</tt>) describes | |
404 | both the type and organization of the color data, for example KCMY (black | |
405 | first) instead of CMYK and RGBA (RGB + alpha) instead of RGB.</p> | |
406 | ||
407 | </blockquote> | |
408 | ||
409 | <p>You read the page header using the | |
5a738aea MS |
410 | <a href="#cupsRasterReadHeader2"><code>cupsRasterReadHeader2</code></a> |
411 | function:</p> | |
b423cd4c | 412 | |
5a738aea MS |
413 | <pre class="example"> |
414 | #include <cups/raster.h>> | |
b423cd4c | 415 | |
5a738aea MS |
416 | <a href="#cups_raster_t">cups_raster_t</a> *ras = <a href="#cupsRasterOpen">cupsRasterOpen</a>(0, CUPS_RASTER_READ); |
417 | <a href="#cups_page_header2_t">cups_page_header2_t</a> header; | |
b423cd4c | 418 | |
5a738aea MS |
419 | while (<a href="#cupsRasterReadHeader2">cupsRasterReadHeader2</a>(ras, &header)) |
420 | { | |
421 | /* setup this page */ | |
b423cd4c | 422 | |
5a738aea MS |
423 | /* read raster data */ |
424 | ||
425 | /* finish this page */ | |
426 | } | |
b423cd4c | 427 | </pre> |
428 | ||
5a738aea MS |
429 | <p>After the page dictionary comes the page data which is a full-resolution, |
430 | possibly compressed bitmap representing the page in the printer's output | |
431 | colorspace. You read uncompressed raster data using the | |
432 | <a href="#cupsRasterReadPixels"><code>cupsRasterReadPixels</code></a> | |
433 | function. A <code>for</code> loop is normally used to read the page one line | |
434 | at a time:</p> | |
b423cd4c | 435 | |
5a738aea MS |
436 | <pre class="example"> |
437 | #include <cups/raster.h>> | |
