1501 font of the text are specified independent of the pixmap. Typically

1502 these attributes will come from the face of the surrounding text,

1503 unless a face is specified for the glyph in which the image appears.
|

1504 'mono-pixmap
|
|
1505 Displayed as a mono pixmap (a pixmap with only two colors where the
|
|
1506 foreground and background can be specified independent of the pixmap;

1514 'subwindow
|

1515 A child window that is treated as an image. This allows (e.g.)
|
|
1516 another program to be responsible for drawing into the window.
|
|
1517 'widget

|
1524 `mono-pixmap', followed by `color-pixmap', followed by `pointer'. For
|
|
1525 the other normal image formats, the most natural types are
|
|
1526 `color-pixmap', followed by `mono-pixmap', followed by `pointer'. For
|
|
1527 the string and formatted-string formats, the most natural types are
|
|
1528 `text', followed by `mono-pixmap' (not currently implemented),
|
|
1529 followed by `color-pixmap' (not currently implemented). For MS
|
|
1530 Windows resources, the most natural type for pointer resources is
|
|
1531 `pointer', and for the others it's `color-pixmap'. The other formats
|
|
1532 can only be instantiated as one type. (If you want to control more
|
|
1533 specifically the order of the types into which an image is
|
|
1534 instantiated, just call `make-image-instance' repeatedly until it
|
|
1535 succeeds, passing less and less preferred destination types each
|
|
1536 time.)
|
|
1537
|
|
1538 See `make-image-specifier' for a description of the different image
|
|
1539 instantiator formats.
|
428
|
1540
|
|
1541 If DEST-TYPES is omitted, all possible types are allowed.
|
|
1542
|
442
|
1543 DOMAIN specifies the domain to which the image instance will be attached.
|
|
1544 This domain is termed the \"governing domain\". The type of the governing
|
|
1545 domain depends on the image instantiator format. (Although, more correctly,
|
|
1546 it should probably depend on the image instance type.) For example, pixmap
|
|
1547 image instances are specific to a device, but widget image instances are
|
|
1548 specific to a particular XEmacs window because in order to display such a
|
|
1549 widget when two windows onto the same buffer want to display the widget,
|
|
1550 two separate underlying widgets must be created. (That's because a widget
|
|
1551 is actually a child window-system window, and all window-system windows have
|
|
1552 a unique existence on the screen.) This means that the governing domain for
|
|
1553 a pixmap image instance will be some device (most likely, the only existing
|
|
1554 device), whereas the governing domain for a widget image instance will be
|
|
1555 some XEmacs window.
|
|
1556
|
|
1557 If you specify an overly general DOMAIN (e.g. a frame when a window was
|
|
1558 wanted), an error is signaled. If you specify an overly specific DOMAIN
|
|
1559 \(e.g. a window when a device was wanted), the corresponding general domain
|
|
1560 is fetched and used instead. For `make-image-instance', it makes no
|
|
1561 difference whether you specify an overly specific domain or the properly
|
|
1562 general domain derived from it. However, it does matter when creating an
|
|
1563 image instance by instantiating a specifier or glyph (e.g. with
|
|
1564 `glyph-image-instance'), because the more specific domain causes spec lookup
|
|
1565 to start there and proceed to more general domains. (It would also matter
|
|
1566 when creating an image instance with an instantiator format of `inherit',
|
|
1567 but we currently disallow this. #### We should fix this.)
|
|
1568
|
|
1569 If omitted, DOMAIN defaults to the selected window.
|
|
1570
|
444
|
1571 NOERROR controls what happens when the image cannot be generated.
|
428
|
1572 If nil, an error message is generated. If t, no messages are
|
|
1573 generated and this function returns nil. If anything else, a warning
|
440
|
1574 message is generated and this function returns nil.
