| 28 Heavily modified / rewritten by Andy Piper. | |
| 29 | |
| 30 Earliest glyph support, Jamie Zawinski for 19.8? | |
| 31 subwindow support added by Chuck Thompson | |
| 32 additional XPM support added by Chuck Thompson | |
| 33 initial X-Face support added by Stig | |
| 34 Majorly rewritten/restructured by Ben Wing, including creation of | |
| 35 glyph and image-instance objects, for 19.12/19.13 | |
| 36 GIF/JPEG/etc. support originally in this file -- see glyph-eimage.c | |
| 37 Pointer/icon overhaul, more restructuring by Ben Wing for 19.14 | |
| 38 Many changes for color work and optimizations by Jareth Hein for 21.0 | |
| 39 Switch of GIF/JPEG/PNG to new EImage intermediate code by Jareth Hein for 21.0 | |
| 40 TIFF code by Jareth Hein for 21.0 | |
| 41 Generalization for ms-windows by Andy Piper for 21.0 | |
| 42 TODO: | |
| 43 Convert images.el to C and stick it in here? | |

| 1551 Image-instance objects encapsulate the way a particular image (pixmap, | |
| 1552 etc.) is displayed on a particular device. In most circumstances, you | |
| 1553 do not need to directly create image instances; use a glyph instead. | |
| 1554 However, it may occasionally be useful to explicitly create image | |
| 1555 instances, if you want more control over the instantiation process. | |
| 1556 | |
| 1557 DATA is an image instantiator, which describes the image; see | |
| 442 | 1558 `make-image-specifier' for a description of the allowed values. |
| 428 | 1559 |
| 1560 DEST-TYPES should be a list of allowed image instance types that can | |
| 1561 be generated. The recognized image instance types are | |
| 1562 | |
| 2959 | 1563 `nothing' |
| 428 | 1564 Nothing is displayed. |
| 2959 | 1565 `text' |
| 428 | 1566 Displayed as text. The foreground and background colors and the |
| 1567 font of the text are specified independent of the pixmap. Typically | |
| 1568 these attributes will come from the face of the surrounding text, | |
| 1569 unless a face is specified for the glyph in which the image appears. | |
| 2959 | 1570 `mono-pixmap' |
| 428 | 1571 Displayed as a mono pixmap (a pixmap with only two colors where the |
| 1572 foreground and background can be specified independent of the pixmap; | |
| 1573 typically the pixmap assumes the foreground and background colors of | |
| 1574 the text around it, unless a face is specified for the glyph in which | |
| 1575 the image appears). | |
| 2959 | 1576 `color-pixmap' |
| 428 | 1577 Displayed as a color pixmap. |
| 2959 | 1578 `pointer' |
| 428 | 1579 Used as the mouse pointer for a window. |
| 2959 | 1580 `subwindow' |
| 428 | 1581 A child window that is treated as an image. This allows (e.g.) |
| 1582 another program to be responsible for drawing into the window. | |
| 2959 | 1583 `widget' |
| 428 | 1584 A child window that contains a window-system widget, e.g. a push |
| 442 | 1585 button, text field, or slider. |
| 1586 | |
| 1587 The DEST-TYPES list is unordered. If multiple destination types are | |
| 1588 possible for a given instantiator, the "most natural" type for the | |
| 1589 instantiator's format is chosen. (For XBM, the most natural types are | |
| 1590 `mono-pixmap', followed by `color-pixmap', followed by `pointer'. For | |
| 1591 the other normal image formats, the most natural types are | |
| 1592 `color-pixmap', followed by `mono-pixmap', followed by `pointer'. For | |
| 1593 the string and formatted-string formats, the most natural types are | |
| 1594 `text', followed by `mono-pixmap' (not currently implemented), | |
| 1595 followed by `color-pixmap' (not currently implemented). For MS | |
| 1596 Windows resources, the most natural type for pointer resources is | |
| 1597 `pointer', and for the others it's `color-pixmap'. The other formats | |
| 1598 can only be instantiated as one type. (If you want to control more | |
| 1599 specifically the order of the types into which an image is | |
| 1600 instantiated, just call `make-image-instance' repeatedly until it | |
| 1601 succeeds, passing less and less preferred destination types each | |
| 1602 time.) | |
| 1603 | |
| 1604 See `make-image-specifier' for a description of the different image | |
| 1605 instantiator formats. | |
| 428 | 1606 |
| 1607 If DEST-TYPES is omitted, all possible types are allowed. | |
| 1608 | |
| 442 | 1609 DOMAIN specifies the domain to which the image instance will be attached. |
| 1610 This domain is termed the \"governing domain\". The type of the governing | |
| 1611 domain depends on the image instantiator format. (Although, more correctly, | |
| 1612 it should probably depend on the image instance type.) For example, pixmap | |
| 1613 image instances are specific to a device, but widget image instances are | |
| 1614 specific to a particular XEmacs window because in order to display such a | |
| 1615 widget when two windows onto the same buffer want to display the widget, | |
| 1616 two separate underlying widgets must be created. (That's because a widget | |
| 1617 is actually a child window-system window, and all window-system windows have | |
| 1618 a unique existence on the screen.) This means that the governing domain for | |
| 1619 a pixmap image instance will be some device (most likely, the only existing | |
| 1620 device), whereas the governing domain for a widget image instance will be | |
| 1621 some XEmacs window. | |
| 1622 | |
| 1623 If you specify an overly general DOMAIN (e.g. a frame when a window was | |
| 1624 wanted), an error is signaled. If you specify an overly specific DOMAIN | |
| 1625 \(e.g. a window when a device was wanted), the corresponding general domain | |
| 1626 is fetched and used instead. For `make-image-instance', it makes no | |
| 1627 difference whether you specify an overly specific domain or the properly | |
| 1628 general domain derived from it. However, it does matter when creating an | |
| 1629 image instance by instantiating a specifier or glyph (e.g. with | |
| 1630 `glyph-image-instance'), because the more specific domain causes spec lookup | |
| 1631 to start there and proceed to more general domains. (It would also matter | |
| 1632 when creating an image instance with an instantiator format of `inherit', | |
| 1633 but we currently disallow this. #### We should fix this.) | |
| 1634 | |
| 1635 If omitted, DOMAIN defaults to the selected window. | |
| 1636 | |
| 444 | 1637 NOERROR controls what happens when the image cannot be generated. |
| 428 | 1638 If nil, an error message is generated. If t, no messages are |
| 1639 generated and this function returns nil. If anything else, a warning | |
| 440 | 1640 message is generated and this function returns nil. |

| 5496 display tables that apply (obtained by calling `specifier-instance' on | |
| 5497 `current-display-table' and any overriding display tables specified in | |
| 5498 currently active faces). The first entry found that matches the | |
| 5499 character determines how the character is displayed. If there is no | |
| 5500 matching entry, the default display method is used. (Non-control | |
| 5501 characters are displayed as themselves and control characters are | |
| 5502 displayed according to the buffer-local variable `ctl-arrow'. Control | |
| 5503 characters are further affected by `control-arrow-glyph' and | |
| 5504 `octal-escape-glyph'.) | |
| 5505 | |
| 5506 Each instantiator in this specifier and the display-table specifiers | |
| 5507 in faces is a display table or a list of such tables. If a list, each | |
| 5508 table will be searched in turn for an entry matching a particular | |
| 5509 character. Each display table is one of | |
| 5510 | |
| 5511 -- a vector, specifying values for characters starting at 0 | |
| 5512 -- a char table, either of type `char' or `generic' | |
| 5513 -- a range table | |
| 5514 | |
| 5515 Each entry in a display table should be one of | |
| 5516 | |
| 5517 -- nil (this entry is ignored and the search continues) | |
| 5518 -- a character (use this character; if it happens to be the same as | |
