1114 Image-instance objects encapsulate the way a particular image (pixmap,

1115 etc.) is displayed on a particular device. In most circumstances, you
|
|
|
1116 do not need to directly create image instances; use a glyph instead.
|
|
|
1117 However, it may occasionally be useful to explicitly create image
|
|
|
1118 instances, if you want more control over the instantiation process.
|
|
|
1119
|
|
|
1120 DATA is an image instantiator, which describes the image; see
|
|
|
1121 `image-specifier-p' for a description of the allowed values.
|
|
|
1122
|
|

1123 DEST-TYPES should be a list of allowed image instance types that can
|
|
|
1124 be generated. The recognized image instance types are
|
|
|
1125
|
|
|
1126 'nothing
|
|
|
1127 Nothing is displayed.
|
|
|
1128 'text
|
|
|
1129 Displayed as text. The foreground and background colors and the
|
|
|
1130 font of the text are specified independent of the pixmap. Typically
|
|
|
1131 these attributes will come from the face of the surrounding text,
|
|
|
1132 unless a face is specified for the glyph in which the image appears.
|
|
|
1133 'mono-pixmap
|
|
|
1134 Displayed as a mono pixmap (a pixmap with only two colors where the
|
|
|
1135 foreground and background can be specified independent of the pixmap;
|
|
|
1136 typically the pixmap assumes the foreground and background colors of
|
|
|
1137 the text around it, unless a face is specified for the glyph in which
|
|
|
1138 the image appears).
|
|
|
1139 'color-pixmap
|
|
|
1140 Displayed as a color pixmap.
|
|
|
1141 'pointer
|
|
|
1142 Used as the mouse pointer for a window.
|
|
|
1143 'subwindow
|
|
|
1144 A child window that is treated as an image. This allows (e.g.)
|
|
|
1145 another program to be responsible for drawing into the window.
|
|
|
1146 Not currently implemented.
|
|
|
1147
|
|
|
1148 The DEST-TYPES list is unordered. If multiple destination types
|
|
185
|
1149 are possible for a given instantiator, the "most natural" type
|
|
0
|
1150 for the instantiator's format is chosen. (For XBM, the most natural
|
|
|
1151 types are `mono-pixmap', followed by `color-pixmap', followed by
|
|
|
1152 `pointer'. For the other normal image formats, the most natural
|
|
|
1153 types are `color-pixmap', followed by `mono-pixmap', followed by
|
|
|
1154 `pointer'. For the string and formatted-string formats, the most
|
|
|
1155 natural types are `text', followed by `mono-pixmap' (not currently
|
|
|
1156 implemented), followed by `color-pixmap' (not currently implemented).
|
|
|
1157 The other formats can only be instantiated as one type. (If you
|
|
|
1158 want to control more specifically the order of the types into which
|
|
|
1159 an image is instantiated, just call `make-image-instance' repeatedly
|
|
|
1160 until it succeeds, passing less and less preferred destination types
|
|
|
1161 each time.
|
|
|
1162
|
|
|
1163 If DEST-TYPES is omitted, all possible types are allowed.
|
|
|
1164
|
|
|
1165 NO-ERROR controls what happens when the image cannot be generated.
|
|
|
1166 If nil, an error message is generated. If t, no messages are
|
|
|
1167 generated and this function returns nil. If anything else, a warning
|
|
|
1168 message is generated and this function returns nil.

2397 1) pixmap data can be very long, and thus the hashing and

2399 2) It's not so likely that we'll run into things that are EQUAL
|
|
|
2400 but not EQ (that can happen a lot with faces, because their
|
|
|
2401 specifiers are copied around); but pixmaps tend not to be

|
2402 in faces.
|
|

2403

|
|
|
2632 An image specifier is used for images (pixmaps and the like). It is used
|
|
|
2633 to describe the actual image in a glyph. It is instanced as an image-
|
|
|
2634 instance.
|
|
|
2635
|
|
|
2636 Image instantiators come in many formats: `xbm', `xpm', `gif', `jpeg',
|
|
|
2637 etc. This describes the format of the data describing the image. The
|
|
|
2638 resulting image instances also come in many types -- `mono-pixmap',
|
|
|
2639 `color-pixmap', `text', `pointer', etc. This refers to the behavior of
|
|
|
2640 the image and the sorts of places it can appear. (For example, a
|
|
|
2641 color-pixmap image has fixed colors specified for it, while a
|
|
185
|
2642 mono-pixmap image comes in two unspecified shades "foreground" and
|
|
|
2643 "background" that are determined from the face of the glyph or
|
|
0
|
2644 surrounding text; a text image appears as a string of text and has an
|
|
|
2645 unspecified foreground, background, and font; a pointer image behaves
|
|
|
2646 like a mono-pixmap image but can only be used as a mouse pointer
|
|
|
2647 \[mono-pixmap images cannot be used as mouse pointers]; etc.) It is
|
|
|
2648 important to keep the distinction between image instantiator format and
|
|
|
2649 image instance type in mind. Typically, a given image instantiator
|
|
|
2650 format can result in many different image instance types (for example,
|
|
|
2651 `xpm' can be instanced as `color-pixmap', `mono-pixmap', or `pointer';
|
|
|
2652 whereas `cursor-font' can be instanced only as `pointer'), and a
|
|
|
2653 particular image instance type can be generated by many different
|
|
|
2654 image instantiator formats (e.g. `color-pixmap' can be generated by `xpm',
|
|
|
2655 `gif', `jpeg', etc.).
|

|
|
0
|
2717 (XEmacs tries to guess what format the data is in. If X support

2718 exists, the data string will be checked to see if it names a filename.
|
|

2720 sort of pixmap or pointer will be created. [This includes picking up

2721 any specified hotspot or associated mask file.] Otherwise, if `pointer'
|

2722 is one of the allowable image-instance types and the string names a
|

2723 valid cursor-font name, the image will be created as a pointer.
|
|
|
2724 Otherwise, the image will be displayed as text. If no X support
|

2725 exists, the image will always be displayed as text.)
|

2726 'inherit
|
|
|
2727 Inherit from the background-pixmap property of a face.
|
|
|
2728
|
|
|
2729 The valid keywords are:
|
|
|
2730
|
|
|
2731 :data
|
|
|
2732 (Inline data. For most formats above, this should be a string. For
|
|
|
2733 XBM images, this should be a list of three elements: width, height, and
|
|
|
2734 a string of bit data. This keyword is not valid for instantiator
|
|
|
2735 formats `nothing' and `inherit'.)
|
|
|
2736 :file
|
|
|
2737 (Data is contained in a file. The value is the name of this file.
|
|
|
2738 If both :data and :file are specified, the image is created from
|
|
|
2739 what is specified in :data and the string in :file becomes the
|
|
|
2740 value of the `image-instance-file-name' function when applied to
|
|
|
2741 the resulting image-instance. This keyword is not valid for
|
|
|
2742 instantiator formats `nothing', `string', `formatted-string',
|
|
122
|
2743 `cursor-font', `font', `autodetect', and `inherit'.)
|
|
0
|
2744 :foreground
|
|
|
2745 :background
|
|
384
|
2746 (For `xbm', `xface', `cursor-font', `widget' and `font'. These keywords
|
|
0
|
2747 allow you to explicitly specify foreground and background colors.
|
|
|
2748 The argument should be anything acceptable to `make-color-instance'.
|
|
|
2749 This will cause what would be a `mono-pixmap' to instead be colorized
|
|
|
2750 as a two-color color-pixmap, and specifies the foreground and/or
|
|
|
2751 background colors for a pointer instead of black and white.)
|
|
|
2752 :mask-data
|
|
|
2753 (For `xbm' and `xface'. This specifies a mask to be used with the
|
|
|
2754 bitmap. The format is a list of width, height, and bits, like for
|
|
|
2755 :data.)
|
|
|
2756 :mask-file
|
|
|
2757 (For `xbm' and `xface'. This specifies a file containing the mask data.
|
|
|
2758 If neither a mask file nor inline mask data is given for an XBM image,
|
|
|
2759 and the XBM image comes from a file, XEmacs will look for a mask file
|
|
185
|
2760 with the same name as the image file but with "Mask" or "msk"
|
|
|
2761 appended. For example, if you specify the XBM file "left_ptr"
|
|
|
2762 [usually located in "/usr/include/X11/bitmaps"], the associated
|
|
|
2763 mask file "left_ptrmsk" will automatically be picked up.)
|
|
0
|
2764 :hotspot-x
|
|
|
2765 :hotspot-y
|
|
|
2766 (For `xbm' and `xface'. These keywords specify a hotspot if the image
|
|
|
2767 is instantiated as a `pointer'. Note that if the XBM image file
|
|
|
2768 specifies a hotspot, it will automatically be picked up if no
|
|
|
2769 explicit hotspot is given.)
|
|
|
2770 :color-symbols
|
|
|
2771 (Only for `xpm'. This specifies an alist that maps strings
|
|
|
2772 that specify symbolic color names to the actual color to be used
|
|
|
2773 for that symbolic color (in the form of a string or a color-specifier
|
|
|
2774 object). If this is not specified, the contents of `xpm-color-symbols'
|
|
|
2775 are used to generate the alist.)
|
|
|
2776 :face
|
|
|
2777 (Only for `inherit'. This specifies the face to inherit from.)
|
|
|
2778
|
|
|
2779 If instead of a vector, the instantiator is a string, it will be
|
|
|
2780 converted into a vector by looking it up according to the specs in the
|
|
|
2781 `console-type-image-conversion-list' (q.v.) for the console type of
|
|
|
2782 the domain (usually a window; sometimes a frame or device) over which
|
|
|
2783 the image is being instantiated.
|
|
|
2784
|
|
|
2785 If the instantiator specifies data from a file, the data will be read
|
|
|
2786 in at the time that the instantiator is added to the image (which may
|
|
|
2787 be well before when the image is actually displayed), and the
|
|
|
2788 instantiator will be converted into one of the inline-data forms, with
|
|
|
2789 the filename retained using a :file keyword. This implies that the
|
|
|
2790 file must exist when the instantiator is added to the image, but does
|
|
|
2791 not need to exist at any other time (e.g. it may safely be a temporary
|
|
|
2792 file).

3535 redisplay. We have two caches - a per-window instance cache that

3536 keeps track of subwindows on a window, these are linked to their

3537 instantiator in the hashtable and when the instantiator goes away

3545 the cache it will fill up with crud that will only get removed when
