 413 <h2 class='title'><a name='OVERVIEW'>Overview</a></h2>
 414
 415 <p>The CUPS PPD API provides read-only access the data in PostScript Printer
 416 Description ("PPD") files which are used for all printers with a driver. With
 417 it you can obtain the data necessary to display printer options to users, mark
 418 option choices and check for conflicting choices, and output marked choices in
 419 PostScript output. The <a href="#ppd_file_t"><code>ppd_file_t</code></a>
 420 structure contains all of the information in a PPD file.</p>
 421
 422 <blockquote><b>Note:</b>
 423
 424 <p>The CUPS PPD API uses the terms "option" and "choice" instead of the Adobe
 425 terms "MainKeyword" and "OptionKeyword" to refer to specific printer options and
 426 features. CUPS also treats option ("MainKeyword") and choice ("OptionKeyword")
 427 values as case-insensitive strings, so option "InputSlot" and choice "Upper"
 428 are equivalent to "inputslot" and "upper", respectively.</p>
 429 </blockquote>
 430
 431 <h3><a name="LOADING">Loading a PPD File</a></h3>
 432
 433 <p>The <a href="#ppdOpenFile"><code>ppdOpenFile</code></a> function "opens" a
 434 PPD file and loads it into memory. For example, the following code opens the
 435 current printer's PPD file in a CUPS filter:</p>
 436
 437 <pre class="example">

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

 665 <p class="discussion">This function attempts to resolve any conflicts in a marked PPD, returning
 666 a list of option changes that are required to resolve any conflicts.  On
 667 input, &quot;num_options&quot; and &quot;options&quot; contain any pending option changes that
 668 have not yet been marked, while &quot;option&quot; and &quot;choice&quot; contain the most recent
 669 selection which may or may not be in &quot;num_options&quot; or &quot;options&quot;.<br>
 670 <br>
 671 On successful return, &quot;num_options&quot; and &quot;options&quot; are updated to contain
 672 &quot;option&quot; and &quot;choice&quot; along with any changes required to resolve conflicts
 673 specified in the PPD file.  If option conflicts cannot be resolved,
 674 &quot;num_options&quot; and &quot;options&quot; are not changed.
 675
 676 <code>ppdResolveConflicts</code> uses one of two sources of option constraint
 677 information.  The preferred constraint information is defined by
 678 <code>cupsUIConstraints</code> and <code>cupsUIResolver</code> attributes - in this
 679 case, the PPD file provides constraint resolution actions.  In this case,
 680 it should not be possible for @ppdResolveConflicts@ to fail, however it
 681 will do so if a resolver loop is detected.<br>
 682 <br>
 683 The backup constraint infomration is defined by the
 684 <code>UIConstraints</code> and <code>NonUIConstraints</code> attributes.  These
 685 constraints are resolved algorithmically by selecting the default choice
 686 for the conflicting option.  Unfortunately, this method is far more likely
 687 to fail.
