492 | <p>The CUPS PPD API provides read-only access the data in PostScript Printer |
| 493 | Description ("PPD") files which are used for all printers with a driver. With | |
| 79e1d494 MS |
494 | it you can obtain the data necessary to display printer options to users, mark |
| 495 | option choices and check for conflicting choices, and output marked choices in | |
| 496 | PostScript output. The <a href="#ppd_file_t"><code>ppd_file_t</code></a> | |
| 497 | structure contains all of the information in a PPD file.</p> | |
| 498 | ||
| 499 | <blockquote><b>Note:</b> | |
| 500 | ||
| 501 | <p>The CUPS PPD API uses the terms "option" and "choice" instead of the Adobe | |
| 502 | terms "MainKeyword" and "OptionKeyword" to refer to specific printer options and | |
| 503 | features. CUPS also treats option ("MainKeyword") and choice ("OptionKeyword") | |
| 504 | values as case-insensitive strings, so option "InputSlot" and choice "Upper" | |
| 505 | are equivalent to "inputslot" and "upper", respectively.</p> | |
| 506 | </blockquote> | |

| 5a738aea | 508 | <h3><a name="LOADING">Loading a PPD File</a></h3> |
| ef416fc2 | 509 | |
| 5a738aea MS |
510 | <p>The <a href="#ppdOpenFile"><code>ppdOpenFile</code></a> function "opens" a |
| 511 | PPD file and loads it into memory. For example, the following code opens the | |
| 512 | current printer's PPD file in a CUPS filter:</p> | |
| ef416fc2 | 513 | |
| 5a738aea MS |
514 | <pre class="example"> |
| 515 | #include <cups/ppd.h> | |
| ef416fc2 | 516 | |
| 5a738aea | 517 | <a href="#ppd_file_t">ppd_file_t</a> *ppd = <a href="#ppdOpenFile">ppdOpenFile</a>(getenv("PPD")); |
| ef416fc2 | 518 | </pre> |
| 519 | ||
| 5a738aea MS |
520 | <p>The return value is a pointer to a new |
| 521 | <a href="#ppd_file_t"><code>ppd_file_t</code></a> structure or <code>NULL</code> | |
| 522 | if the PPD file does not exist or cannot be loaded. The | |
| 523 | <a href="#ppdClose"><code>ppdClose</code></a> function frees the memory used | |
| 524 | by the structure:</p> | |
| 525 | ||
| 526 | <pre class="example"> | |
| 527 | #include <cups/ppd.h> | |
| 528 | ||
| 529 | <a href="#ppd_file_t">ppd_file_t</a> *ppd; | |
| 530 | ||
| 531 | <a href="#ppdClose">ppdClose</a>(ppd); | |
| 532 | </pre> | |
| 533 | ||
| 79e1d494 MS |
534 | <p>Once closed, pointers to the <a href="#ppd_file_t"><code>ppd_file_t</code></a> |
| 535 | structure and any data in it will no longer be valid.</p> | |
| 536 | ||
| 5a738aea MS |
537 | <h3><a name="OPTIONS_AND_GROUPS">Options and Groups</a></h3> |
| 538 | ||
| 539 | <p>PPD files support multiple options, which are stored in arrays of | |
| 540 | <a href="#ppd_option_t"><code>ppd_option_t</code></a> and | |
| 541 | <a href="#ppd_choice_t"><code>ppd_choice_t</code></a> structures.</p> | |
| 542 | ||
| 543 | <p>Each option in turn is associated with a group stored in a | |
| 544 | <a href="#ppd_group_t"><code>ppd_group_t</code></a> structure. Groups can be | |
| 545 | specified in the PPD file; if an option is not associated with a group | |
| 546 | then it is put in an automatically-generated "General" group. Groups can also | |
| 547 | have sub-groups, however CUPS currently ignores sub-groups because of past | |
| 548 | abuses of this functionality.</p> | |
| 549 | ||
| 79e1d494 | 550 | <p>Option choices are selected by marking them using one of three functions. The |
| 5a738aea MS |
551 | first is <a href="#ppdMarkDefaults"><code>ppdMarkDefaults</code></a> which |
| 552 | selects all of the default options in the PPD file:</p> | |
| 553 | ||
| 554 | <pre class="example"> | |
| 555 | #include <cups/ppd.h> | |
| 556 | ||
| 557 | <a href="#ppd_file_t">ppd_file_t</a> *ppd; | |
| 558 | ||
| 559 | <a href="#ppdMarkDefaults">ppdMarkDefaults</a>(ppd); | |
| 560 | </pre> | |
| 561 | ||
| 562 | <p>The second is <a href="#ppdMarkOption"><code>ppdMarkOption</code></a> | |
| 563 | which selects a single option choice in the PPD file. For example, the following | |
| 79e1d494 | 564 | code selects the upper paper tray:</p> |
| 5a738aea MS |
565 | |
| 566 | <pre class="example"> | |
| 567 | #include <cups/ppd.h> | |
| 568 | ||
| 569 | <a href="#ppd_file_t">ppd_file_t</a> *ppd; | |
| 570 | ||
| 79e1d494 | 571 | <a href="#ppdMarkOption">ppdMarkOption</a>(ppd, "InputSlot", "Upper"); |
| 5a738aea MS |
572 | </pre> |
| 573 | ||
| 574 | <p>The last function is | |
| 575 | <a href="#cupsMarkOptions"><code>cupsMarkOptions</code></a> which selects | |
| 576 | multiple option choices in the PPD file from an array of CUPS options, mapping | |
| 577 | IPP attributes like "media" and "sides" to their corresponding PPD options. You | |
| 578 | typically use this function in a print filter with | |
| 579 | <code>cupsParseOptions</code> and | |
| 580 | <a href="#ppdMarkDefaults"><code>ppdMarkDefaults</code></a> to select all of | |
| 581 | the option choices needed for the job, for example:</p> | |
| 582 | ||
| 583 | <pre class="example"> | |
| 584 | #include <cups/ppd.h> | |
| 585 | ||
| 586 | <a href="#ppd_file_t">ppd_file_t</a> *ppd = <a href="#ppdOpenFile">ppdOpenFile</a>(getenv("PPD")); | |
| 587 | cups_option_t *options = NULL; | |
| 588 | int num_options = cupsParseOptions(argv[5], 0, &options); | |
| 589 | ||
| 590 | <a href="#ppdMarkDefaults">ppdMarkDefaults</a>(ppd); | |
| 591 | <a href="#cupsMarkOptions">cupsMarkOptions</a>(ppd, num_options, options); | |
| 79e1d494 | 592 | cupsFreeOptions(num_options, options); |
| 5a738aea MS |
593 | </pre> |
| 594 | ||
| 595 | <h3><a name="CONSTRAINTS">Constraints</a></h3> | |
| 596 | ||
| 597 | <p>PPD files support specification of conflict conditions, called | |
| 598 | constraints, between different options. Constraints are stored in an array of | |
| 599 | <a href="#ppd_const_t"><code>ppd_const_t</code></a> structures which specify | |
| 600 | the options and choices that conflict with each other. The | |
| 601 | <a href="#ppdConflicts"><code>ppdConflicts</code></a> function tells you | |
| 79e1d494 MS |
602 | how many of the selected options are incompatible. Since constraints are |
| 603 | normally specified in pairs, the returned value is typically an even number.</p> | |
| 5a738aea MS |
604 | |
| 605 | <h3><a name="PAGE_SIZES">Page Sizes</a></h3> | |
| 606 | ||
| 607 | <p>Page sizes are special options which have physical dimensions and margins | |
| 608 | associated with them. The size information is stored in | |
| 609 | <a href="#ppd_size_t"><code>ppd_size_t</code></a> structures and is available | |
| 610 | by looking up the named size with the | |
| 611 | <a href="#ppdPageSize"><code>ppdPageSize</code></a> function. The page size and | |
| 612 | margins are returned in units called points; there are 72 points per inch. If | |
| 613 | you pass <code>NULL</code> for the size, the currently selected size is | |
| 614 | returned:</p> | |
| 615 | ||
| 616 | <pre class="example"> | |
| 617 | #include <cups/ppd.h> | |
| 618 | ||
| 619 | <a href="#ppd_file_t">ppd_file_t</a> *ppd; | |
| 620 | <a href="#ppd_size_t">ppd_size_t</a> *size = <a href="#ppdPageSize">ppdPageSize</a>(ppd, NULL); | |
| 621 | </pre> | |
| 622 | ||
| 623 | <p>Besides the standard page sizes listed in a PPD file, some printers | |
| 624 | support variable or custom page sizes. Custom page sizes are supported if the | |
| 625 | <code>variables_sizes</code> member of the | |
| 626 | <a href="#ppd_file_t"><code>ppd_file_t</code></a> structure is non-zero. | |
| 627 | The <code>custom_min</code>, <code>custom_max</code>, and | |
| 628 | <code>custom_margins</code> members of the | |
| 629 | <a href="#ppd_file_t"><code>ppd_file_t</code></a> structure define the limits | |
| 630 | of the printable area. To get the resulting media size, use a page size string | |
| 631 | of the form "Custom.<I>width</I>x<I>length</I>", where "width" and "length" are | |
| 632 | in points. Custom page size names can also be specified in inches | |
| 633 | ("Custom.<i>width</i>x<i>height</i>in"), centimeters | |
| 634 | ("Custom.<i>width</i>x<i>height</i>cm"), or millimeters | |
| 635 | ("Custom.<i>width</i>x<i>height</i>mm"):</p> | |
| 636 | ||
| 637 | <pre class="example"> | |
| 638 | #include <cups/ppd.h> | |
| 639 | ||
| 640 | <a href="#ppd_file_t">ppd_file_t</a> *ppd; | |
| 641 | ||
| 642 | /* Get an 576x720 point custom page size */ | |
| 643 | <a href="#ppd_size_t">ppd_size_t</a> *size = <a href="#ppdPageSize">ppdPageSize</a>(ppd, "Custom.576x720"); | |
| 644 | ||
| 645 | /* Get an 8x10 inch custom page size */ | |
| 646 | <a href="#ppd_size_t">ppd_size_t</a> *size = <a href="#ppdPageSize">ppdPageSize</a>(ppd, "Custom.8x10in"); | |
| 647 | ||
| 648 | /* Get a 100x200 millimeter custom page size */ | |
| 649 | <a href="#ppd_size_t">ppd_size_t</a> *size = <a href="#ppdPageSize">ppdPageSize</a>(ppd, "Custom.100x200mm"); | |
| 650 | ||
| 651 | /* Get a 12.7x34.5 centimeter custom page size */ | |
| 652 | <a href="#ppd_size_t">ppd_size_t</a> *size = <a href="#ppdPageSize">ppdPageSize</a>(ppd, "Custom.12.7x34.5cm"); | |
| 653 | </pre> | |
| 654 | ||
| 79e1d494 MS |
655 | <p>If the PPD does not support variable page sizes, the |
| 656 | <a href="#ppdPageSize"><code>ppdPageSize</code></a> function will return | |
| 657 | <code>NULL</code>.</p> | |
| 658 | ||
| 5a738aea MS |
659 | <h3><a name="ATTRIBUTES">Attributes</a></h3> |
| 660 | ||
| 661 | <p>Every PPD file is composed of one or more attributes. Most of these | |
| 662 | attributes are used to define groups, options, choices, and page sizes, | |
| 79e1d494 MS |
663 | however several informational attributes may be present which you can access |
| 664 | in your program or filter. Attributes normally look like one of the following | |
| 665 | examples in a PPD file:</p> | |
| 5a738aea MS |
666 | |
| 667 | <pre class="example"> | |
| 668 | *name: "value" | |
| 669 | *name spec: "value" | |
| 670 | *name spec/text: "value" | |
| 671 | </pre> | |
| 672 | ||
| 673 | <p>The <a href="#ppdFindAttr"><code>ppdFindAttr</code></a> and | |
| 674 | <a href="#ppdFindNextAttr"><code>ppdFindNextAttr</code></a> functions find the | |
| 675 | first and next instances, respectively, of the named attribute with the given | |
| 676 | "spec" string and return a <a href="#ppd_attr_t"><code>ppd_attr_t</code></a> | |
| 677 | structure. If you provide a NULL specifier string, all attributes with the | |
| 678 | given name will be returned. For example, the following code lists all of the | |
| 679 | <code>Product</code> attributes in a PPD file:</p> | |
| 680 | ||
| 681 | <pre class="example"> | |
| 682 | #include <cups/ppd.h> | |
| 683 | ||
| 684 | <a href="#ppd_file_t">ppd_file_t</a> *ppd; | |
| 685 | <a href="#ppd_attr_t">ppd_attr_t</a> *attr; | |
| 686 | ||
| 687 | for (attr = <a href="#ppdFindAttr">ppdFindAttr</a>(ppd, "Product", NULL); | |
| 688 | attr != NULL; | |
| 689 | attr = <a href="#ppdFindNextAttr">ppdFindNextAttr</a>(ppd, "Product", NULL)) | |
| 690 | puts(attr->value); | |

| 06d4e77b MS |
750 | specified in the PPD file and 1 is returned.<br> |
| 751 | <br> | |
| 752 | If option conflicts cannot be resolved, "num_options" and "options" are not | |
| 753 | changed and 0 is returned.<br> | |
| 754 | <br> | |
| 755 | When resolving conflicts, <code>cupsResolveConflicts</code> does not consider | |
| 756 | changes to the current page size (<code>media</code>, <code>PageSize</code>, and | |
| 757 | <code>PageRegion</code>) or to the most recent option specified in "option". | |
| 758 | Thus, if the only way to resolve a conflict is to change the page size | |
| 759 | or the option the user most recently changed, <code>cupsResolveConflicts</code> | |
| 760 | will return 0 to indicate it was unable to resolve the conflicts.<br> | |
| 761 | <br> | |
| 762 | The <code>cupsResolveConflicts</code> function uses one of two sources of option | |
| 763 | constraint information. The preferred constraint information is defined by | |
| 66ab9486 | 764 | <code>cupsUIConstraints</code> and <code>cupsUIResolver</code> attributes - in this |
| 06d4e77b | 765 | case, the PPD file provides constraint resolution actions.<br> |
| 66ab9486 | 766 | <br> |
| 06d4e77b | 767 | The backup constraint information is defined by the |
| 66ab9486 | 768 | <code>UIConstraints</code> and <code>NonUIConstraints</code> attributes. These |
| 06d4e77b MS |
769 | constraints are resolved algorithmically by first selecting the default |
| 770 | choice for the conflicting option, then iterating over all possible choices | |
| 771 | until a non-conflicting option choice is found. | |
