|
|
|
1247 Nothing is displayed.
|
|
|
1248 'text
|
|
|
1249 Displayed as text. The foreground and background colors and the
|
|
|
1250 font of the text are specified independent of the pixmap. Typically
|
|
|
1251 these attributes will come from the face of the surrounding text,

|
|
1252 unless a face is specified for the glyph in which the image appears.

|

|
|
|
1255 foreground and background can be specified independent of the pixmap;

1256 typically the pixmap assumes the foreground and background colors of

1257 the text around it, unless a face is specified for the glyph in which

1258 the image appears).

|
|
|
1262 Used as the mouse pointer for a window.
|
|
|
1263 'subwindow
|
|
|
1264 A child window that is treated as an image. This allows (e.g.)
|
|
|
1265 another program to be responsible for drawing into the window.
|

398

185

1271 are possible for a given instantiator, the "most natural" type

|
|
|
1273 types are `mono-pixmap', followed by `color-pixmap', followed by
|
|
|
1274 `pointer'. For the other normal image formats, the most natural
|
|
|
1275 types are `color-pixmap', followed by `mono-pixmap', followed by
|
|
|
1276 `pointer'. For the string and formatted-string formats, the most
|
|
|
1277 natural types are `text', followed by `mono-pixmap' (not currently
|
|
|
1278 implemented), followed by `color-pixmap' (not currently implemented).
|
|
|
1279 The other formats can only be instantiated as one type. (If you
|
|
|
1280 want to control more specifically the order of the types into which
|
|

1281 an image is instantiated, just call `make-image-instance' repeatedly

3118
|
|
|
3119 An image specifier is used for images (pixmaps and the like). It is used
|
|
|
3120 to describe the actual image in a glyph. It is instanced as an image-
|
|
|
3121 instance.
|
|
|
3122
|
|
|
3123 Image instantiators come in many formats: `xbm', `xpm', `gif', `jpeg',
|
|
|
3124 etc. This describes the format of the data describing the image. The
|
|
|
3125 resulting image instances also come in many types -- `mono-pixmap',
|
|
|
3126 `color-pixmap', `text', `pointer', etc. This refers to the behavior of
|
|
|
3127 the image and the sorts of places it can appear. (For example, a
|
|
|
3128 color-pixmap image has fixed colors specified for it, while a
|
|
185
|
3129 mono-pixmap image comes in two unspecified shades "foreground" and
|
|
|
3130 "background" that are determined from the face of the glyph or
|
|
0
|
3131 surrounding text; a text image appears as a string of text and has an
|
|
|
3132 unspecified foreground, background, and font; a pointer image behaves
|
|
|
3133 like a mono-pixmap image but can only be used as a mouse pointer
|
|
|
3134 \[mono-pixmap images cannot be used as mouse pointers]; etc.) It is
|
|
|
3135 important to keep the distinction between image instantiator format and
|
|
|
3136 image instance type in mind. Typically, a given image instantiator
|
|
|
3137 format can result in many different image instance types (for example,
|
|
|
3138 `xpm' can be instanced as `color-pixmap', `mono-pixmap', or `pointer';
|
|
|
3139 whereas `cursor-font' can be instanced only as `pointer'), and a
|
|
|
3140 particular image instance type can be generated by many different
|
|
|
3141 image instantiator formats (e.g. `color-pixmap' can be generated by `xpm',
|
|
|
3142 `gif', `jpeg', etc.).
|
|
|
3143
|
|

3144 See `make-image-instance' for a more detailed discussion of image
|
|
|
3145 instance types.

|
|

3226 Inherit from the background-pixmap property of a face.

3229
|
|
|
3230 :data
|
|
|
3231 (Inline data. For most formats above, this should be a string. For
|
|
|
3232 XBM images, this should be a list of three elements: width, height, and
|
|
|
3233 a string of bit data. This keyword is not valid for instantiator
|
|
|
3234 formats `nothing' and `inherit'.)
|
|
|
3235 :file
|
|
|
3236 (Data is contained in a file. The value is the name of this file.
|
|
|
3237 If both :data and :file are specified, the image is created from
|
|
|
3238 what is specified in :data and the string in :file becomes the
|
|
|
3239 value of the `image-instance-file-name' function when applied to
|
|
|
3240 the resulting image-instance. This keyword is not valid for
|
|
|
3241 instantiator formats `nothing', `string', `formatted-string',
|
|
122
|
3242 `cursor-font', `font', `autodetect', and `inherit'.)
|
|
0
|
3243 :foreground
|
|
|
3244 :background
|
|
384
|
3245 (For `xbm', `xface', `cursor-font', `widget' and `font'. These keywords
|
|
0
|
3246 allow you to explicitly specify foreground and background colors.
|
|
|
3247 The argument should be anything acceptable to `make-color-instance'.
|
|
|
3248 This will cause what would be a `mono-pixmap' to instead be colorized
|
|
|
3249 as a two-color color-pixmap, and specifies the foreground and/or
|
|
|
3250 background colors for a pointer instead of black and white.)
|
|
|
3251 :mask-data
|
|
|
3252 (For `xbm' and `xface'. This specifies a mask to be used with the
|
|
|
3253 bitmap. The format is a list of width, height, and bits, like for
|
|
|
3254 :data.)
|
|
|
3255 :mask-file
|
|
|
3256 (For `xbm' and `xface'. This specifies a file containing the mask data.
|
|
|
3257 If neither a mask file nor inline mask data is given for an XBM image,
|
|
|
3258 and the XBM image comes from a file, XEmacs will look for a mask file
|
|
185
|
3259 with the same name as the image file but with "Mask" or "msk"
|
|
|
3260 appended. For example, if you specify the XBM file "left_ptr"
|
|
|
3261 [usually located in "/usr/include/X11/bitmaps"], the associated
|
|
|
3262 mask file "left_ptrmsk" will automatically be picked up.)
|
|
0
|
3263 :hotspot-x
|
|
|
3264 :hotspot-y
|
|
|
3265 (For `xbm' and `xface'. These keywords specify a hotspot if the image
|
|
|
3266 is instantiated as a `pointer'. Note that if the XBM image file
|
|
|
3267 specifies a hotspot, it will automatically be picked up if no
|
|
|
3268 explicit hotspot is given.)
|
|
|
3269 :color-symbols
|
|
|
3270 (Only for `xpm'. This specifies an alist that maps strings
|
|
|
3271 that specify symbolic color names to the actual color to be used
|
|
|
3272 for that symbolic color (in the form of a string or a color-specifier
|
|
|
3273 object). If this is not specified, the contents of `xpm-color-symbols'
|
|
|
3274 are used to generate the alist.)
|
|
|
3275 :face
|
|
398
|
3276 (Only for `inherit'. This specifies the face to inherit from.
|
|
|
3277 For widget glyphs this also specifies the face to use for
|
|
|
3278 display. It defaults to gui-element-face.)
|
|
|
3279
|
|
|
3280 Keywords accepted as menu item specs are also accepted by widget
|
|
|
3281 glyphs. These are `:selected', `:active', `:suffix', `:keys',
|
|
|
3282 `:style', `:filter', `:config', `:included', `:key-sequence',
|
|
|
3283 `:accelerator', `:label' and `:callback'.
|
|
0
|
3284
|
|
|
3285 If instead of a vector, the instantiator is a string, it will be
|
|
|
3286 converted into a vector by looking it up according to the specs in the
|
|
|
3287 `console-type-image-conversion-list' (q.v.) for the console type of
|
|
|
3288 the domain (usually a window; sometimes a frame or device) over which
|
|
|
3289 the image is being instantiated.
|
|
|
3290
|
|
|
3291 If the instantiator specifies data from a file, the data will be read
|
|
|
3292 in at the time that the instantiator is added to the image (which may
|
|
|
3293 be well before when the image is actually displayed), and the
|
|
|
3294 instantiator will be converted into one of the inline-data forms, with
|
|
|
3295 the filename retained using a :file keyword. This implies that the
|
|
|
3296 file must exist when the instantiator is added to the image, but does
|
|
|
3297 not need to exist at any other time (e.g. it may safely be a temporary
|
|
|
3298 file).

3893 the dirty flag after redisplaying it as it may exist in other

3894 contexts. When we have redisplayed we need to know which glyphs to

3895 reset the dirty flags on - the glyph_cachels give us a nice list we

384

4056 not display them. It is problematic deciding what to do in

4057 redisplay. We have two caches - a per-window instance cache that
|
|

4058 keeps track of subwindows on a window, these are linked to their
|
|
|
4059 instantiator in the hashtable and when the instantiator goes away
|

4060 we want the instance to go away also. However we also have a
|
|

4061 per-frame instance cache that we use to determine if a subwindow is
|
|
|
4062 obscuring an area that we want to clear. We need to be able to flip
|
|
|
4063 through this quickly so a hashtable is not suitable hence the
|
|
|
4064 subwindow_cachels. The question is should we just not mark

|
398
|
4065 instances in the subwindow_cachels or should we try and invalidate
|
|
384

4066 the cache at suitable points in redisplay? If we don't invalidate
|
|
|
4067 the cache it will fill up with crud that will only get removed when
|
|
|
4068 the frame is deleted. So invalidation is good, the question is when

4069 and whether we mark as well. Go for the simple option - don't mark,
