|
|

996 Nothing is displayed.
|
|
|
997 'text
|
|
|
998 Displayed as text. The foreground and background colors and the
|
|
|
999 font of the text are specified independent of the pixmap. Typically
|
|
|
1000 these attributes will come from the face of the surrounding text,
|
|
|
1001 unless a face is specified for the glyph in which the image appears.
|
|
|
1002 'mono-pixmap
|
|
|
1003 Displayed as a mono pixmap (a pixmap with only two colors where the
|
|
|
1004 foreground and background can be specified independent of the pixmap;
|
|
|
1005 typically the pixmap assumes the foreground and background colors of
|
|
|
1006 the text around it, unless a face is specified for the glyph in which
|
|
|
1007 the image appears).
|

|
|

1009 Displayed as a color pixmap.

|
|
|
1011 Used as the mouse pointer for a window.
|
|
|
1012 'subwindow
|
|
|
1013 A child window that is treated as an image. This allows (e.g.)
|
|
|
1014 another program to be responsible for drawing into the window.

|
|
185
|
1018 are possible for a given instantiator, the "most natural" type
|

0
|
1019 for the instantiator's format is chosen. (For XBM, the most natural
|
|
|
1020 types are `mono-pixmap', followed by `color-pixmap', followed by
|
|
|
1021 `pointer'. For the other normal image formats, the most natural
|
|
|
1022 types are `color-pixmap', followed by `mono-pixmap', followed by
|
|
|
1023 `pointer'. For the string and formatted-string formats, the most
|
|
|
1024 natural types are `text', followed by `mono-pixmap' (not currently
|
|
|
1025 implemented), followed by `color-pixmap' (not currently implemented).
|
|
|
1026 The other formats can only be instantiated as one type. (If you
|
|
|
1027 want to control more specifically the order of the types into which
|
|
|
1028 an image is instantiated, just call `make-image-instance' repeatedly
|

1029 until it succeeds, passing less and less preferred destination types
|
|

1030 each time.

1032 If DEST-TYPES is omitted, all possible types are allowed.

1036 generated and this function returns nil. If anything else, a warning

|
|
|
2318 An image specifier is used for images (pixmaps and the like). It is used
|
|
|
2319 to describe the actual image in a glyph. It is instanced as an image-
|
|
|
2320 instance.
|
|
|
2321
|
|
|
2322 Image instantiators come in many formats: `xbm', `xpm', `gif', `jpeg',
|
|
|
2323 etc. This describes the format of the data describing the image. The
|
|
|
2324 resulting image instances also come in many types -- `mono-pixmap',
|
|
|
2325 `color-pixmap', `text', `pointer', etc. This refers to the behavior of
|
|
|
2326 the image and the sorts of places it can appear. (For example, a
|
|
|
2327 color-pixmap image has fixed colors specified for it, while a
|
|
185
|
2328 mono-pixmap image comes in two unspecified shades "foreground" and
|
|
|
2329 "background" that are determined from the face of the glyph or
|
|
0
|
2330 surrounding text; a text image appears as a string of text and has an
|
|
|
2331 unspecified foreground, background, and font; a pointer image behaves
|
|
|
2332 like a mono-pixmap image but can only be used as a mouse pointer
|
|
|
2333 \[mono-pixmap images cannot be used as mouse pointers]; etc.) It is
|
|
|
2334 important to keep the distinction between image instantiator format and
|
|
|
2335 image instance type in mind. Typically, a given image instantiator
|
|
|
2336 format can result in many different image instance types (for example,
|
|
|
2337 `xpm' can be instanced as `color-pixmap', `mono-pixmap', or `pointer';
|
|
|
2338 whereas `cursor-font' can be instanced only as `pointer'), and a
|
|
|
2339 particular image instance type can be generated by many different
|
|
|
2340 image instantiator formats (e.g. `color-pixmap' can be generated by `xpm',
|
|
|
2341 `gif', `jpeg', etc.).
|
|
|
2342

|
|

2344 instance types.

2404 sort of pixmap or pointer will be created. [This includes picking up
|
|
|
2405 any specified hotspot or associated mask file.] Otherwise, if `pointer'
|
|
|
2406 is one of the allowable image-instance types and the string names a
|
|
|
2407 valid cursor-font name, the image will be created as a pointer.
|
|
|
2408 Otherwise, the image will be displayed as text. If no X support
|
|
|
2409 exists, the image will always be displayed as text.)
|
|
|
2410 'inherit
|
|
|
2411 Inherit from the background-pixmap property of a face.
|
|
|
2412
|
|
|
2413 The valid keywords are:
|
|
|
2414
|
|
|
2415 :data
|
|
|
2416 (Inline data. For most formats above, this should be a string. For
|
|
|
2417 XBM images, this should be a list of three elements: width, height, and
|
|
|
2418 a string of bit data. This keyword is not valid for instantiator
|
|
|
2419 formats `nothing' and `inherit'.)
|
|
|
2420 :file
|
|
|
2421 (Data is contained in a file. The value is the name of this file.
|
|
|
2422 If both :data and :file are specified, the image is created from
|
|
|
2423 what is specified in :data and the string in :file becomes the
|
|
|
2424 value of the `image-instance-file-name' function when applied to
|
|
|
2425 the resulting image-instance. This keyword is not valid for
|
|
|
2426 instantiator formats `nothing', `string', `formatted-string',
|
|
122
|
2427 `cursor-font', `font', `autodetect', and `inherit'.)
|
|
0
|
2428 :foreground
|
|
|
2429 :background
|
|
|
2430 (For `xbm', `xface', `cursor-font', and `font'. These keywords
|
|
|
2431 allow you to explicitly specify foreground and background colors.
|
|
|
2432 The argument should be anything acceptable to `make-color-instance'.
|
|
|
2433 This will cause what would be a `mono-pixmap' to instead be colorized
|
|
|
2434 as a two-color color-pixmap, and specifies the foreground and/or
|
|
|
2435 background colors for a pointer instead of black and white.)
|
|
|
2436 :mask-data
|
|
|
2437 (For `xbm' and `xface'. This specifies a mask to be used with the
|
|
|
2438 bitmap. The format is a list of width, height, and bits, like for
|
|
|
2439 :data.)
|
|
|
2440 :mask-file
|
|
|
2441 (For `xbm' and `xface'. This specifies a file containing the mask data.
|
|
|
2442 If neither a mask file nor inline mask data is given for an XBM image,
|
|
|
2443 and the XBM image comes from a file, XEmacs will look for a mask file
|
|
185
|
2444 with the same name as the image file but with "Mask" or "msk"
|
|
|
2445 appended. For example, if you specify the XBM file "left_ptr"
|
|
|
2446 [usually located in "/usr/include/X11/bitmaps"], the associated
|
|
|
2447 mask file "left_ptrmsk" will automatically be picked up.)
|
|
0
|
2448 :hotspot-x
|
|
|
2449 :hotspot-y
|
|
|
2450 (For `xbm' and `xface'. These keywords specify a hotspot if the image
|
|
|
2451 is instantiated as a `pointer'. Note that if the XBM image file
|
|
|
2452 specifies a hotspot, it will automatically be picked up if no
|
|
|
2453 explicit hotspot is given.)
|
|
|
2454 :color-symbols
|
|
|
2455 (Only for `xpm'. This specifies an alist that maps strings
|
|
|
2456 that specify symbolic color names to the actual color to be used
|
|
|
2457 for that symbolic color (in the form of a string or a color-specifier
|
|
|
2458 object). If this is not specified, the contents of `xpm-color-symbols'
|
|
|
2459 are used to generate the alist.)
|
|
|
2460 :face
|
|
|
2461 (Only for `inherit'. This specifies the face to inherit from.)
|
|
|
2462
|
|
|
2463 If instead of a vector, the instantiator is a string, it will be
|
|
|
2464 converted into a vector by looking it up according to the specs in the
|
|
|
2465 `console-type-image-conversion-list' (q.v.) for the console type of
|
|
|
2466 the domain (usually a window; sometimes a frame or device) over which
|
|
|
2467 the image is being instantiated.
|
|
|
2468
|
|
|
2469 If the instantiator specifies data from a file, the data will be read
|
|
|
2470 in at the time that the instantiator is added to the image (which may
|
|
|
2471 be well before when the image is actually displayed), and the
|
|
|
2472 instantiator will be converted into one of the inline-data forms, with
|
|
|
2473 the filename retained using a :file keyword. This implies that the
|
|
|
2474 file must exist when the instantiator is added to the image, but does
|
|
|
2475 not need to exist at any other time (e.g. it may safely be a temporary
|
|
|
2476 file).
