1109 Image-instance objects encapsulate the way a particular image (pixmap,

1111 do not need to directly create image instances; use a glyph instead.

1112 However, it may occasionally be useful to explicitly create image
|
|
|
1113 instances, if you want more control over the instantiation process.
|
|
|
1114
|
|
|
1115 DATA is an image instantiator, which describes the image; see
|
|
|
1116 `image-specifier-p' for a description of the allowed values.
|
|
|
1117
|

|
|
|
1119 be generated. The recognized image instance types are
|
|
|
1120
|
|
|
1121 'nothing
|
|
|
1122 Nothing is displayed.
|
|
|
1123 'text
|
|
|
1124 Displayed as text. The foreground and background colors and the
|
|
|
1125 font of the text are specified independent of the pixmap. Typically
|
|
|
1126 these attributes will come from the face of the surrounding text,
|
|
|
1127 unless a face is specified for the glyph in which the image appears.
|
|
|
1128 'mono-pixmap
|
|
|
1129 Displayed as a mono pixmap (a pixmap with only two colors where the
|
|
|
1130 foreground and background can be specified independent of the pixmap;
|
|
|
1131 typically the pixmap assumes the foreground and background colors of
|
|
|
1132 the text around it, unless a face is specified for the glyph in which
|
|
|
1133 the image appears).
|
|
|
1134 'color-pixmap
|
|
|
1135 Displayed as a color pixmap.
|
|
|
1136 'pointer
|
|
|
1137 Used as the mouse pointer for a window.
|
|
|
1138 'subwindow
|
|
|
1139 A child window that is treated as an image. This allows (e.g.)
|
|
|
1140 another program to be responsible for drawing into the window.
|
|
|
1141 Not currently implemented.
|
|
|
1142
|
|
|
1143 The DEST-TYPES list is unordered. If multiple destination types
|
|
185
|
1144 are possible for a given instantiator, the "most natural" type
|
|
0
|
1145 for the instantiator's format is chosen. (For XBM, the most natural
|
|
|
1146 types are `mono-pixmap', followed by `color-pixmap', followed by
|
|
|
1147 `pointer'. For the other normal image formats, the most natural
|
|
|
1148 types are `color-pixmap', followed by `mono-pixmap', followed by
|
|
|
1149 `pointer'. For the string and formatted-string formats, the most
|
|
|
1150 natural types are `text', followed by `mono-pixmap' (not currently
|
|
|
1151 implemented), followed by `color-pixmap' (not currently implemented).
|
|
|
1152 The other formats can only be instantiated as one type. (If you
|
|
|
1153 want to control more specifically the order of the types into which
|
|
|
1154 an image is instantiated, just call `make-image-instance' repeatedly
|
|
|
1155 until it succeeds, passing less and less preferred destination types
|
|
|
1156 each time.
|
|
|
1157
|
|
|
1158 If DEST-TYPES is omitted, all possible types are allowed.
|

|
1159
|

|
|

1161 If nil, an error message is generated. If t, no messages are

1162 generated and this function returns nil. If anything else, a warning

1163 message is generated and this function returns nil.

2552
|
|
|
2553 An image specifier is used for images (pixmaps and the like). It is used
|
|
|
2554 to describe the actual image in a glyph. It is instanced as an image-
|
|
|
2555 instance.
|
|
|
2556
|
|
|
2557 Image instantiators come in many formats: `xbm', `xpm', `gif', `jpeg',
|
|
|
2558 etc. This describes the format of the data describing the image. The
|
|
|
2559 resulting image instances also come in many types -- `mono-pixmap',
|
|
|
2560 `color-pixmap', `text', `pointer', etc. This refers to the behavior of
|
|
|
2561 the image and the sorts of places it can appear. (For example, a
|
|
|
2562 color-pixmap image has fixed colors specified for it, while a
|
|
185
|
2563 mono-pixmap image comes in two unspecified shades "foreground" and
|
|
|
2564 "background" that are determined from the face of the glyph or
|
|
0
|
2565 surrounding text; a text image appears as a string of text and has an
|
|
|
2566 unspecified foreground, background, and font; a pointer image behaves
|
|
|
2567 like a mono-pixmap image but can only be used as a mouse pointer
|
|
|
2568 \[mono-pixmap images cannot be used as mouse pointers]; etc.) It is
|
|
|
2569 important to keep the distinction between image instantiator format and
|
|
|
2570 image instance type in mind. Typically, a given image instantiator
|
|
|
2571 format can result in many different image instance types (for example,
|
|
|
2572 `xpm' can be instanced as `color-pixmap', `mono-pixmap', or `pointer';
|
|
|
2573 whereas `cursor-font' can be instanced only as `pointer'), and a
|
|
|
2574 particular image instance type can be generated by many different
|
|
|
2575 image instantiator formats (e.g. `color-pixmap' can be generated by `xpm',
|
|
|
2576 `gif', `jpeg', etc.).
|
|
|
2577
|

|
|
|
2579 instance types.

|
|

2653 (Inline data. For most formats above, this should be a string. For

2654 XBM images, this should be a list of three elements: width, height, and
|
|

2655 a string of bit data. This keyword is not valid for instantiator
|
|
|
2656 formats `nothing' and `inherit'.)
|

2657 :file

2658 (Data is contained in a file. The value is the name of this file.
|
|
|
2659 If both :data and :file are specified, the image is created from

|

2660 what is specified in :data and the string in :file becomes the
|
|
|
2661 value of the `image-instance-file-name' function when applied to
|
|
|
2662 the resulting image-instance. This keyword is not valid for
|

2663 instantiator formats `nothing', `string', `formatted-string',
|
|
122
|
2664 `cursor-font', `font', `autodetect', and `inherit'.)

0

2665 :foreground
|
|
|
2666 :background
|
|
384
|
2667 (For `xbm', `xface', `cursor-font', `widget' and `font'. These keywords
|
|
0
|
2668 allow you to explicitly specify foreground and background colors.
|
|
|
2669 The argument should be anything acceptable to `make-color-instance'.
|
|
|
2670 This will cause what would be a `mono-pixmap' to instead be colorized
|
|
|
2671 as a two-color color-pixmap, and specifies the foreground and/or
|
|
|
2672 background colors for a pointer instead of black and white.)
|
|
|
2673 :mask-data
|
|
|
2674 (For `xbm' and `xface'. This specifies a mask to be used with the
|
|
|
2675 bitmap. The format is a list of width, height, and bits, like for
|
|
|
2676 :data.)
|
|
|
2677 :mask-file
|
|
|
2678 (For `xbm' and `xface'. This specifies a file containing the mask data.
|
|
|
2679 If neither a mask file nor inline mask data is given for an XBM image,
|
|
|
2680 and the XBM image comes from a file, XEmacs will look for a mask file
|
|
185
|
2681 with the same name as the image file but with "Mask" or "msk"
|
|
|
2682 appended. For example, if you specify the XBM file "left_ptr"
|
|
|
2683 [usually located in "/usr/include/X11/bitmaps"], the associated
|
|
|
2684 mask file "left_ptrmsk" will automatically be picked up.)

0
|
2685 :hotspot-x
|
|
|
2686 :hotspot-y
|
|
|
2687 (For `xbm' and `xface'. These keywords specify a hotspot if the image
|
|
|
2688 is instantiated as a `pointer'. Note that if the XBM image file
|
|
|
2689 specifies a hotspot, it will automatically be picked up if no
|
|
|
2690 explicit hotspot is given.)
|
|
|
2691 :color-symbols
|
|
|
2692 (Only for `xpm'. This specifies an alist that maps strings
|
|
|
2693 that specify symbolic color names to the actual color to be used
|
|
|
2694 for that symbolic color (in the form of a string or a color-specifier
|
|
|
2695 object). If this is not specified, the contents of `xpm-color-symbols'
|
|
|
2696 are used to generate the alist.)
|
|
|
2697 :face
|
|
|
2698 (Only for `inherit'. This specifies the face to inherit from.)
|
|
|
2699
|
|
|
2700 If instead of a vector, the instantiator is a string, it will be
|
|
|
2701 converted into a vector by looking it up according to the specs in the

3455 not display them. It is problematic deciding what to do in
|
|
|
3456 redisplay. We have two caches - a per-window instance cache that
|
|
|
3457 keeps track of subwindows on a window, these are linked to their
|
|
|
3458 instantiator in the hashtable and when the instantiator goes away
|
|
|
3459 we want the instance to go away also. However we also have a
|
|
|
3460 per-frame instance cache that we use to determine if a subwindow is
|
|
|
3461 obscuring an area that we want to clear. We need to be able to flip
|
|
|
3462 through this quickly so a hashtable is not suitable hence the
|
|
|
3463 subwindow_cachels. The question is should we just not mark
|
|
|
3464 instances in the subwindow_cachelsnor should we try and invalidate
|
|
|
3465 the cache at suitable points in redisplay? If we don't invalidate
|
|
|
3466 the cache it will fill up with crud that will only get removed when
|
|
|
3467 the frame is deleted. So invalidation is good, the question is when
|
|
|
3468 and whether we mark as well. Go for the simple option - don't mark,
