 409 <h2 class='title'><a name='OVERVIEW'>Overview</a></h2>
 410
 411 <p>The CUPS PPD API provides read-only access the data in PostScript Printer
 412 Description ("PPD") files which are used for all printers with a driver. With
 413 it you can obtain the data necessary to display printer options to users, mark
 414 option choices and check for conflicting choices, and output marked choices in
 415 PostScript output. The <a href="#ppd_file_t"><code>ppd_file_t</code></a>
 416 structure contains all of the information in a PPD file.</p>
 417
 418 <blockquote><b>Note:</b>
 419
 420 <p>The CUPS PPD API uses the terms "option" and "choice" instead of the Adobe
 421 terms "MainKeyword" and "OptionKeyword" to refer to specific printer options and
 422 features. CUPS also treats option ("MainKeyword") and choice ("OptionKeyword")
 423 values as case-insensitive strings, so option "InputSlot" and choice "Upper"
 424 are equivalent to "inputslot" and "upper", respectively.</p>
 425 </blockquote>
 426
 427 <h3><a name="LOADING">Loading a PPD File</a></h3>
 428
 429 <p>The <a href="#ppdOpenFile"><code>ppdOpenFile</code></a> function "opens" a
 430 PPD file and loads it into memory. For example, the following code opens the
 431 current printer's PPD file in a CUPS filter:</p>
 432
 433 <pre class="example">
 434 #include &lt;cups/ppd.h&gt;
 435
 436 <a href="#ppd_file_t">ppd_file_t</a> *ppd = <a href="#ppdOpenFile">ppdOpenFile</a>(getenv("PPD"));
 437 </pre>
 438
 439 <p>The return value is a pointer to a new
 440 <a href="#ppd_file_t"><code>ppd_file_t</code></a> structure or <code>NULL</code>
 441 if the PPD file does not exist or cannot be loaded. The
 442 <a href="#ppdClose"><code>ppdClose</code></a> function frees the memory used
 443 by the structure:</p>
 444
 445 <pre class="example">
 446 #include &lt;cups/ppd.h&gt;
 447
 448 <a href="#ppd_file_t">ppd_file_t</a> *ppd;
 449
 450 <a href="#ppdClose">ppdClose</a>(ppd);
 451 </pre>
 452
 453 <p>Once closed, pointers to the <a href="#ppd_file_t"><code>ppd_file_t</code></a>
 454 structure and any data in it will no longer be valid.</p>
 455
 456 <h3><a name="OPTIONS_AND_GROUPS">Options and Groups</a></h3>
 457
 458 <p>PPD files support multiple options, which are stored in arrays of
 459 <a href="#ppd_option_t"><code>ppd_option_t</code></a> and
 460 <a href="#ppd_choice_t"><code>ppd_choice_t</code></a> structures.</p>
 461
 462 <p>Each option in turn is associated with a group stored in a
 463 <a href="#ppd_group_t"><code>ppd_group_t</code></a> structure. Groups can be
 464 specified in the PPD file; if an option is not associated with a group
 465 then it is put in an automatically-generated "General" group. Groups can also
 466 have sub-groups, however CUPS currently ignores sub-groups because of past
 467 abuses of this functionality.</p>
 468
 469 <p>Option choices are selected by marking them using one of three functions. The
 470 first is <a href="#ppdMarkDefaults"><code>ppdMarkDefaults</code></a> which
 471 selects all of the default options in the PPD file:</p>
 472
 473 <pre class="example">
 474 #include &lt;cups/ppd.h&gt;
 475
 476 <a href="#ppd_file_t">ppd_file_t</a> *ppd;
 477
 478 <a href="#ppdMarkDefaults">ppdMarkDefaults</a>(ppd);
 479 </pre>
 480
 481 <p>The second is <a href="#ppdMarkOption"><code>ppdMarkOption</code></a>
 482 which selects a single option choice in the PPD file. For example, the following
 483 code selects the upper paper tray:</p>
 484
 485 <pre class="example">
 486 #include &lt;cups/ppd.h&gt;
 487
 488 <a href="#ppd_file_t">ppd_file_t</a> *ppd;
 489
 490 <a href="#ppdMarkOption">ppdMarkOption</a>(ppd, "InputSlot", "Upper");
 491 </pre>
 492
 493 <p>The last function is
 494 <a href="#cupsMarkOptions"><code>cupsMarkOptions</code></a> which selects
 495 multiple option choices in the PPD file from an array of CUPS options, mapping
 496 IPP attributes like "media" and "sides" to their corresponding PPD options. You
 497 typically use this function in a print filter with
 498 <code>cupsParseOptions</code> and
 499 <a href="#ppdMarkDefaults"><code>ppdMarkDefaults</code></a> to select all of
 500 the option choices needed for the job, for example:</p>
 501
 502 <pre class="example">
 503 #include &lt;cups/ppd.h&gt;
 504
 505 <a href="#ppd_file_t">ppd_file_t</a> *ppd = <a href="#ppdOpenFile">ppdOpenFile</a>(getenv("PPD"));
 506 cups_option_t *options = NULL;
 507 int num_options = cupsParseOptions(argv[5], 0, &amp;options);
 508
 509 <a href="#ppdMarkDefaults">ppdMarkDefaults</a>(ppd);
 510 <a href="#cupsMarkOptions">cupsMarkOptions</a>(ppd, num_options, options);
 511 cupsFreeOptions(num_options, options);
 512 </pre>
 513
 514 <h3><a name="CONSTRAINTS">Constraints</a></h3>
 515
 516 <p>PPD files support specification of conflict conditions, called
 517 constraints, between different options. Constraints are stored in an array of
 518 <a href="#ppd_const_t"><code>ppd_const_t</code></a> structures which specify
 519 the options and choices that conflict with each other. The
 520 <a href="#ppdConflicts"><code>ppdConflicts</code></a> function tells you
 521 how many of the selected options are incompatible. Since constraints are
 522 normally specified in pairs, the returned value is typically an even number.</p>
 523
 524 <h3><a name="PAGE_SIZES">Page Sizes</a></h3>
 525
 526 <p>Page sizes are special options which have physical dimensions and margins
 527 associated with them. The size information is stored in
 528 <a href="#ppd_size_t"><code>ppd_size_t</code></a> structures and is available
 529 by looking up the named size with the
 530 <a href="#ppdPageSize"><code>ppdPageSize</code></a> function. The page size and
 531 margins are returned in units called points; there are 72 points per inch. If
 532 you pass <code>NULL</code> for the size, the currently selected size is
 533 returned:</p>
 534
 535 <pre class="example">
 536 #include &lt;cups/ppd.h&gt;
 537
 538 <a href="#ppd_file_t">ppd_file_t</a> *ppd;
 539 <a href="#ppd_size_t">ppd_size_t</a> *size = <a href="#ppdPageSize">ppdPageSize</a>(ppd, NULL);
 540 </pre>
 541
 542 <p>Besides the standard page sizes listed in a PPD file, some printers
 543 support variable or custom page sizes. Custom page sizes are supported if the
 544 <code>variables_sizes</code> member of the
 545 <a href="#ppd_file_t"><code>ppd_file_t</code></a> structure is non-zero.
 546 The <code>custom_min</code>, <code>custom_max</code>, and
 547 <code>custom_margins</code> members of the
 548 <a href="#ppd_file_t"><code>ppd_file_t</code></a> structure define the limits
 549 of the printable area. To get the resulting media size, use a page size string
 550 of the form "Custom.<I>width</I>x<I>length</I>", where "width" and "length" are
 551 in points. Custom page size names can also be specified in inches
 552 ("Custom.<i>width</i>x<i>height</i>in"), centimeters
 553 ("Custom.<i>width</i>x<i>height</i>cm"), or millimeters
 554 ("Custom.<i>width</i>x<i>height</i>mm"):</p>
 555
 556 <pre class="example">
 557 #include &lt;cups/ppd.h&gt;
 558
 559 <a href="#ppd_file_t">ppd_file_t</a> *ppd;
 560
 561 /* Get an 576x720 point custom page size */
 562 <a href="#ppd_size_t">ppd_size_t</a> *size = <a href="#ppdPageSize">ppdPageSize</a>(ppd, "Custom.576x720");
 563
 564 /* Get an 8x10 inch custom page size */
 565 <a href="#ppd_size_t">ppd_size_t</a> *size = <a href="#ppdPageSize">ppdPageSize</a>(ppd, "Custom.8x10in");
 566
 567 /* Get a 100x200 millimeter custom page size */
 568 <a href="#ppd_size_t">ppd_size_t</a> *size = <a href="#ppdPageSize">ppdPageSize</a>(ppd, "Custom.100x200mm");
 569
 570 /* Get a 12.7x34.5 centimeter custom page size */
 571 <a href="#ppd_size_t">ppd_size_t</a> *size = <a href="#ppdPageSize">ppdPageSize</a>(ppd, "Custom.12.7x34.5cm");
 572 </pre>
 573
 574 <p>If the PPD does not support variable page sizes, the
 575 <a href="#ppdPageSize"><code>ppdPageSize</code></a> function will return
 576 <code>NULL</code>.</p>
 577
 578 <h3><a name="ATTRIBUTES">Attributes</a></h3>
 579
 580 <p>Every PPD file is composed of one or more attributes. Most of these
 581 attributes are used to define groups, options, choices, and page sizes,
 582 however several informational attributes may be present which you can access
 583 in your program or filter. Attributes normally look like one of the following
 584 examples in a PPD file:</p>
 585
 586 <pre class="example">
 587 *name: "value"
 588 *name spec: "value"
 589 *name spec/text: "value"
 590 </pre>
 591
 592 <p>The <a href="#ppdFindAttr"><code>ppdFindAttr</code></a> and
 593 <a href="#ppdFindNextAttr"><code>ppdFindNextAttr</code></a> functions find the
 594 first and next instances, respectively, of the named attribute with the given
 595 "spec" string and return a <a href="#ppd_attr_t"><code>ppd_attr_t</code></a>
 596 structure. If you provide a NULL specifier string, all attributes with the
 597 given name will be returned. For example, the following code lists all of the
 598 <code>Product</code> attributes in a PPD file:</p>
 599
 600 <pre class="example">
 601 #include &lt;cups/ppd.h&gt;
 602
 603 <a href="#ppd_file_t">ppd_file_t</a> *ppd;
 604 <a href="#ppd_attr_t">ppd_attr_t</a> *attr;
 605
 606 for (attr = <a href="#ppdFindAttr">ppdFindAttr</a>(ppd, "Product", NULL);
 607      attr != NULL;
 608      attr = <a href="#ppdFindNextAttr">ppdFindNextAttr</a>(ppd, "Product", NULL))
 609   puts(attr->value);
