1188 Image-instance objects encapsulate the way a particular image (pixmap,

1190 do not need to directly create image instances; use a glyph instead.

1191 However, it may occasionally be useful to explicitly create image

1192 instances, if you want more control over the instantiation process.

|

1194 DATA is an image instantiator, which describes the image; see

1195 `image-specifier-p' for a description of the allowed values.

|
|
1199
|
|
|
1200 'nothing
|
|
|
1201 Nothing is displayed.
|
|
|
1202 'text
|
|
|
1203 Displayed as text. The foreground and background colors and the
|
|
|
1204 font of the text are specified independent of the pixmap. Typically
|
|
|
1205 these attributes will come from the face of the surrounding text,
|
|
|
1206 unless a face is specified for the glyph in which the image appears.
|
|
|
1207 'mono-pixmap
|
|
|
1208 Displayed as a mono pixmap (a pixmap with only two colors where the
|
|
|
1209 foreground and background can be specified independent of the pixmap;
|
|
|
1210 typically the pixmap assumes the foreground and background colors of
|
|
|
1211 the text around it, unless a face is specified for the glyph in which
|
|
|
1212 the image appears).
|
|
|
1213 'color-pixmap
|
|
|
1214 Displayed as a color pixmap.
|
|
|
1215 'pointer
|
|
|
1216 Used as the mouse pointer for a window.
|
|
|
1217 'subwindow
|
|
|
1218 A child window that is treated as an image. This allows (e.g.)
|
|
|
1219 another program to be responsible for drawing into the window.
|
|
|
1220 'widget
|
|
|
1221 A child window that contains a window-system widget, e.g. a push
|
|
|
1222 button.
|

|

1224 The DEST-TYPES list is unordered. If multiple destination types
|
|
|
1225 are possible for a given instantiator, the "most natural" type
|
|
|
1226 for the instantiator's format is chosen. (For XBM, the most natural
|
|
|
1227 types are `mono-pixmap', followed by `color-pixmap', followed by
|
|
|
1228 `pointer'. For the other normal image formats, the most natural
|
|
|
1229 types are `color-pixmap', followed by `mono-pixmap', followed by
|
|
|
1230 `pointer'. For the string and formatted-string formats, the most
|
|
|
1231 natural types are `text', followed by `mono-pixmap' (not currently
|
|
|
1232 implemented), followed by `color-pixmap' (not currently implemented).
|
|
|
1233 The other formats can only be instantiated as one type. (If you
|
|
|
1234 want to control more specifically the order of the types into which
|
|
|
1235 an image is instantiated, just call `make-image-instance' repeatedly
|
|
|
1236 until it succeeds, passing less and less preferred destination types
|
|
|
1237 each time.
|
|
|
1238
|
|
|
1239 If DEST-TYPES is omitted, all possible types are allowed.
|
|
|
1240
|
|
|
1241 NO-ERROR controls what happens when the image cannot be generated.
|
|
|
1242 If nil, an error message is generated. If t, no messages are
|
|
|
1243 generated and this function returns nil. If anything else, a warning
|

1244 message is generated and this function returns nil.

3005
|
|
|
3006 An image specifier is used for images (pixmaps and the like). It is used
|
|
|
3007 to describe the actual image in a glyph. It is instanced as an image-
|
|
|
3008 instance.
|
|
|
3009
|
|
|
3010 Image instantiators come in many formats: `xbm', `xpm', `gif', `jpeg',
|
|
|
3011 etc. This describes the format of the data describing the image. The
|
|
|
3012 resulting image instances also come in many types -- `mono-pixmap',
|
|
|
3013 `color-pixmap', `text', `pointer', etc. This refers to the behavior of
|
|
|
3014 the image and the sorts of places it can appear. (For example, a
|
|
|
3015 color-pixmap image has fixed colors specified for it, while a
|
|
|
3016 mono-pixmap image comes in two unspecified shades "foreground" and
|
|
|
3017 "background" that are determined from the face of the glyph or
|
|
|
3018 surrounding text; a text image appears as a string of text and has an
|
|
|
3019 unspecified foreground, background, and font; a pointer image behaves
|
|
|
3020 like a mono-pixmap image but can only be used as a mouse pointer
|
|
|
3021 \[mono-pixmap images cannot be used as mouse pointers]; etc.) It is
|
|
|
3022 important to keep the distinction between image instantiator format and
|
|
|
3023 image instance type in mind. Typically, a given image instantiator
|
|
|
3024 format can result in many different image instance types (for example,
|
|
|
3025 `xpm' can be instanced as `color-pixmap', `mono-pixmap', or `pointer';
|
|
|
3026 whereas `cursor-font' can be instanced only as `pointer'), and a
|
|
|
3027 particular image instance type can be generated by many different
|
|
|
3028 image instantiator formats (e.g. `color-pixmap' can be generated by `xpm',
|
|
|
3029 `gif', `jpeg', etc.).
|
|
|
3030

3031 See `make-image-instance' for a more detailed discussion of image
|
|
|
3032 instance types.

3123 (Data is contained in a file. The value is the name of this file.
|
|
|
3124 If both :data and :file are specified, the image is created from
|
|

3125 what is specified in :data and the string in :file becomes the
|
|
|
3126 value of the `image-instance-file-name' function when applied to
|
|
|
3127 the resulting image-instance. This keyword is not valid for
|
|
|
3128 instantiator formats `nothing', `string', `formatted-string',
|
|
|
3129 `cursor-font', `font', `autodetect', and `inherit'.)

3130 :foreground
|
|
|
3131 :background
|
|
|
3132 (For `xbm', `xface', `cursor-font', `widget' and `font'. These keywords
|
|
|
3133 allow you to explicitly specify foreground and background colors.
|
|
|
3134 The argument should be anything acceptable to `make-color-instance'.
|
|
|
3135 This will cause what would be a `mono-pixmap' to instead be colorized
|
|
|
3136 as a two-color color-pixmap, and specifies the foreground and/or
|
|
|
3137 background colors for a pointer instead of black and white.)
|
|
|
3138 :mask-data
|
|
|
3139 (For `xbm' and `xface'. This specifies a mask to be used with the
|
|
|
3140 bitmap. The format is a list of width, height, and bits, like for
|
|
|
3141 :data.)
|
|
|
3142 :mask-file
|
|
|
3143 (For `xbm' and `xface'. This specifies a file containing the mask data.
|
|
|
3144 If neither a mask file nor inline mask data is given for an XBM image,
|
|
|
3145 and the XBM image comes from a file, XEmacs will look for a mask file
|
|
|
3146 with the same name as the image file but with "Mask" or "msk"
|
|
|
3147 appended. For example, if you specify the XBM file "left_ptr"
|
|
|
3148 [usually located in "/usr/include/X11/bitmaps"], the associated
|
|
|
3149 mask file "left_ptrmsk" will automatically be picked up.)
|
|
|
3150 :hotspot-x
|
|
|
3151 :hotspot-y
|
|
|
3152 (For `xbm' and `xface'. These keywords specify a hotspot if the image
|
|
|
3153 is instantiated as a `pointer'. Note that if the XBM image file
|
|
|
3154 specifies a hotspot, it will automatically be picked up if no
|
|
|
3155 explicit hotspot is given.)
|
|
|
3156 :color-symbols
|
|
|
3157 (Only for `xpm'. This specifies an alist that maps strings
|
|
|
3158 that specify symbolic color names to the actual color to be used
|
|
|
3159 for that symbolic color (in the form of a string or a color-specifier
|
|
|
3160 object). If this is not specified, the contents of `xpm-color-symbols'
|
|
|
3161 are used to generate the alist.)
|
|
|
3162 :face
|
|
|
3163 (Only for `inherit'. This specifies the face to inherit from.
|
|
|
3164 For widget glyphs this also specifies the face to use for
|
|
|
3165 display. It defaults to gui-element-face.)
|
|
|
3166
|
|
|
3167 Keywords accepted as menu item specs are also accepted by widget
|
|
|
3168 glyphs. These are `:selected', `:active', `:suffix', `:keys',
|
|
|
3169 `:style', `:filter', `:config', `:included', `:key-sequence',
|
|
|
3170 `:accelerator', `:label' and `:callback'.
|
|
|
3171
|
|
|
3172 If instead of a vector, the instantiator is a string, it will be
|
|
|
3173 converted into a vector by looking it up according to the specs in the
|
|
|
3174 `console-type-image-conversion-list' (q.v.) for the console type of
|
|
|
3175 the domain (usually a window; sometimes a frame or device) over which
|
|
|
3176 the image is being instantiated.
|
|
|
3177
|
|
|
3178 If the instantiator specifies data from a file, the data will be read
|
|
|
3179 in at the time that the instantiator is added to the image (which may
|
|
|
3180 be well before when the image is actually displayed), and the
|
|
|
3181 instantiator will be converted into one of the inline-data forms, with
|
|
|
3182 the filename retained using a :file keyword. This implies that the
|
|
|
3183 file must exist when the instantiator is added to the image, but does
|
|
|
3184 not need to exist at any other time (e.g. it may safely be a temporary
|
|
|
3185 file).

428

3916 not display them. It is problematic deciding what to do in

3917 redisplay. We have two caches - a per-window instance cache that
|
|

3918 keeps track of subwindows on a window, these are linked to their
|
|
|
3919 instantiator in the hashtable and when the instantiator goes away
|

3920 we want the instance to go away also. However we also have a

3921 per-frame instance cache that we use to determine if a subwindow is

3922 obscuring an area that we want to clear. We need to be able to flip
|
|
|
3923 through this quickly so a hashtable is not suitable hence the
|
|
|
3924 subwindow_cachels. The question is should we just not mark
|
|
|
3925 instances in the subwindow_cachels or should we try and invalidate
|
|
|
3926 the cache at suitable points in redisplay? If we don't invalidate
|
|
|
3927 the cache it will fill up with crud that will only get removed when
|
|
|
3928 the frame is deleted. So invalidation is good, the question is when

3929 and whether we mark as well. Go for the simple option - don't mark,
