1186 Image-instance objects encapsulate the way a particular image (pixmap,

1187 etc.) is displayed on a particular device. In most circumstances, you

1188 do not need to directly create image instances; use a glyph instead.

1189 However, it may occasionally be useful to explicitly create image

1190 instances, if you want more control over the instantiation process.

|
|

1192 DATA is an image instantiator, which describes the image; see

1193 `image-specifier-p' for a description of the allowed values.

1197
|
|
|
1198 'nothing
|
|
|
1199 Nothing is displayed.
|
|
|
1200 'text
|
|
|
1201 Displayed as text. The foreground and background colors and the
|
|
|
1202 font of the text are specified independent of the pixmap. Typically
|
|
|
1203 these attributes will come from the face of the surrounding text,
|
|
|
1204 unless a face is specified for the glyph in which the image appears.
|
|
|
1205 'mono-pixmap
|
|
|
1206 Displayed as a mono pixmap (a pixmap with only two colors where the
|
|
|
1207 foreground and background can be specified independent of the pixmap;
|
|
|
1208 typically the pixmap assumes the foreground and background colors of
|
|
|
1209 the text around it, unless a face is specified for the glyph in which
|
|
|
1210 the image appears).
|
|
|
1211 'color-pixmap
|
|
|
1212 Displayed as a color pixmap.
|
|
|
1213 'pointer
|
|
|
1214 Used as the mouse pointer for a window.
|
|
|
1215 'subwindow
|
|
|
1216 A child window that is treated as an image. This allows (e.g.)
|
|
|
1217 another program to be responsible for drawing into the window.
|
|
|
1218 'widget
|
|
|
1219 A child window that contains a window-system widget, e.g. a push
|
|
|
1220 button.

1222 The DEST-TYPES list is unordered. If multiple destination types
|
|
|
1223 are possible for a given instantiator, the "most natural" type
|
|
|
1224 for the instantiator's format is chosen. (For XBM, the most natural
|
|
|
1225 types are `mono-pixmap', followed by `color-pixmap', followed by
|
|
|
1226 `pointer'. For the other normal image formats, the most natural
|
|
|
1227 types are `color-pixmap', followed by `mono-pixmap', followed by
|
|
|
1228 `pointer'. For the string and formatted-string formats, the most
|
|
|
1229 natural types are `text', followed by `mono-pixmap' (not currently
|
|
|
1230 implemented), followed by `color-pixmap' (not currently implemented).
|
|
|
1231 The other formats can only be instantiated as one type. (If you
|
|
|
1232 want to control more specifically the order of the types into which
|
|
|
1233 an image is instantiated, just call `make-image-instance' repeatedly
|
|
|
1234 until it succeeds, passing less and less preferred destination types
|
|
|
1235 each time.
|
|
|
1236
|
|
|
1237 If DEST-TYPES is omitted, all possible types are allowed.
|
|
|
1238
|
|

1239 NO-ERROR controls what happens when the image cannot be generated.
|

1240 If nil, an error message is generated. If t, no messages are
|

1241 generated and this function returns nil. If anything else, a warning
|

1242 message is generated and this function returns nil.

2508 specifiers are copied around); but pixmaps tend not to be

2509 in faces.

2809 Return non-nil if OBJECT is an image specifier.
|
|
|
2810
|
|
|
2811 An image specifier is used for images (pixmaps and the like). It is used
|
|
|
2812 to describe the actual image in a glyph. It is instanced as an image-
|
|
|
2813 instance.
|
|
|
2814
|
|
|
2815 Image instantiators come in many formats: `xbm', `xpm', `gif', `jpeg',
|
|
|
2816 etc. This describes the format of the data describing the image. The
|
|
|
2817 resulting image instances also come in many types -- `mono-pixmap',
|
|
|
2818 `color-pixmap', `text', `pointer', etc. This refers to the behavior of
|
|
|
2819 the image and the sorts of places it can appear. (For example, a
|
|
|
2820 color-pixmap image has fixed colors specified for it, while a
|
|
|
2821 mono-pixmap image comes in two unspecified shades "foreground" and
|
|
|
2822 "background" that are determined from the face of the glyph or
|
|
|
2823 surrounding text; a text image appears as a string of text and has an
|
|
|
2824 unspecified foreground, background, and font; a pointer image behaves
|
|
|
2825 like a mono-pixmap image but can only be used as a mouse pointer
|
|
|
2826 \[mono-pixmap images cannot be used as mouse pointers]; etc.) It is
|
|
|
2827 important to keep the distinction between image instantiator format and
|
|
|
2828 image instance type in mind. Typically, a given image instantiator
|
|
|
2829 format can result in many different image instance types (for example,
|
|
|
2830 `xpm' can be instanced as `color-pixmap', `mono-pixmap', or `pointer';
|
|
|
2831 whereas `cursor-font' can be instanced only as `pointer'), and a
|
|
|
2832 particular image instance type can be generated by many different
|
|
|
2833 image instantiator formats (e.g. `color-pixmap' can be generated by `xpm',
|
|
|
2834 `gif', `jpeg', etc.).
|
|
|
2835
|
|
|
2836 See `make-image-instance' for a more detailed discussion of image
|
|
|
2837 instance types.
|
|
|
2838
|
|
|
2839 An image instantiator should be a string or a vector of the form
|
|
|
2840
|
|
|
2841 [FORMAT :KEYWORD VALUE ...]
|
|
|
2842
|
|
|
2843 i.e. a format symbol followed by zero or more alternating keyword-value
|
|
|
2844 pairs. FORMAT should be one of
|
|
|
2845
|
|
|
2846 'nothing
|
|
|
2847 (Don't display anything; no keywords are valid for this.
|
|
|
2848 Can only be instanced as `nothing'.)
|
|
|
2849 'string
|
|
|
2850 (Display this image as a text string. Can only be instanced
|
|
|
2851 as `text', although support for instancing as `mono-pixmap'
|
|
|
2852 should be added.)
|
|
|
2853 'formatted-string
|
|
|
2854 (Display this image as a text string, with replaceable fields;
|
|
|
2855 not currently implemented.)
|
|
|
2856 'xbm
|
|
|
2857 (An X bitmap; only if X or Windows support was compiled into this XEmacs.
|
|
|
2858 Can be instanced as `mono-pixmap', `color-pixmap', or `pointer'.)
|
|
|
2859 'xpm
|
|
|
2860 (An XPM pixmap; only if XPM support was compiled into this XEmacs.
|
|
|
2861 Can be instanced as `color-pixmap', `mono-pixmap', or `pointer'.)
|
|
|
2862 'xface
|
|
|
2863 (An X-Face bitmap, used to encode people's faces in e-mail messages;
|
|
|
2864 only if X-Face support was compiled into this XEmacs. Can be
|
|
|
2865 instanced as `mono-pixmap', `color-pixmap', or `pointer'.)
|
|
|
2866 'gif
|
|
|
2867 (A GIF87 or GIF89 image; only if GIF support was compiled into this
|
|
|
2868 XEmacs. NOTE: only the first frame of animated gifs will be displayed.
|
|
|
2869 Can be instanced as `color-pixmap'.)
|
|
|
2870 'jpeg
|
|
|
2871 (A JPEG image; only if JPEG support was compiled into this XEmacs.
|
|
|
2872 Can be instanced as `color-pixmap'.)
|
|
|
2873 'png
|
|
|
2874 (A PNG image; only if PNG support was compiled into this XEmacs.
|
|
|
2875 Can be instanced as `color-pixmap'.)
|
|
|
2876 'tiff
|
|
|
2877 (A TIFF image; only if TIFF support was compiled into this XEmacs.
|
|
|
2878 Can be instanced as `color-pixmap'.)
|
|
|
2879 'cursor-font
|
|
|
2880 (One of the standard cursor-font names, such as "watch" or
|
|
|
2881 "right_ptr" under X. Under X, this is, more specifically, any
|
|
|
2882 of the standard cursor names from appendix B of the Xlib manual
|
|
|
2883 [also known as the file <X11/cursorfont.h>] minus the XC_ prefix.
|
|
|
2884 On other window systems, the valid names will be specific to the
|
|
|
2885 type of window system. Can only be instanced as `pointer'.)
|
|
|
2886 'font
|
|
|
2887 (A glyph from a font; i.e. the name of a font, and glyph index into it
|
|
|
2888 of the form "FONT fontname index [[mask-font] mask-index]".
|
|
|
2889 Currently can only be instanced as `pointer', although this should
|
|
|
2890 probably be fixed.)
|
|
|
2891 'subwindow
|
|
|
2892 (An embedded windowing system window.)
|
|
|
2893 'edit-field
|
|
|
2894 (A text editing widget glyph.)
|
|
|
2895 'button
|
|
|
2896 (A button widget glyph; either a push button, radio button or toggle button.)
|
|
|
2897 'tab-control
|
|
|
2898 (A tab widget glyph; a series of user selectable tabs.)
|
|
|
2899 'progress-gauge
|
|
|
2900 (A sliding widget glyph, for showing progress.)
|
|
|
2901 'combo-box
|
|
|
2902 (A drop list of selectable items in a widget glyph, for editing text.)
|
|
|
2903 'label
|
|
|
2904 (A static, text-only, widget glyph; for displaying text.)
|
|
|
2905 'tree-view
|
|
|
2906 (A folding widget glyph.)
|
|
|
2907 'autodetect
|
|
|
2908 (XEmacs tries to guess what format the data is in. If X support
|
|
|
2909 exists, the data string will be checked to see if it names a filename.
|
|
|
2910 If so, and this filename contains XBM or XPM data, the appropriate
|
|
|
2911 sort of pixmap or pointer will be created. [This includes picking up
|
|
|
2912 any specified hotspot or associated mask file.] Otherwise, if `pointer'
|
|
|
2913 is one of the allowable image-instance types and the string names a
|
|
|
2914 valid cursor-font name, the image will be created as a pointer.
|
|
|
2915 Otherwise, the image will be displayed as text. If no X support
|
|
|
2916 exists, the image will always be displayed as text.)
|
|
|
2917 'inherit
|
|
|
2918 Inherit from the background-pixmap property of a face.
|
|
|
2919
|
|
|
2920 The valid keywords are:
|
|
|
2921
|
|
|
2922 :data
|
|
|
2923 (Inline data. For most formats above, this should be a string. For
|
|
|
2924 XBM images, this should be a list of three elements: width, height, and
|
|
|
2925 a string of bit data. This keyword is not valid for instantiator
|
|
|
2926 formats `nothing' and `inherit'.)
|
|
|
2927 :file
|
|
|
2928 (Data is contained in a file. The value is the name of this file.
|
|
|
2929 If both :data and :file are specified, the image is created from
|
|
|
2930 what is specified in :data and the string in :file becomes the
|
|
|
2931 value of the `image-instance-file-name' function when applied to
|
|
|
2932 the resulting image-instance. This keyword is not valid for
|
|
|
2933 instantiator formats `nothing', `string', `formatted-string',
|
|
|
2934 `cursor-font', `font', `autodetect', and `inherit'.)
|
|
|
2935 :foreground
|
|
|
2936 :background
|
|
|
2937 (For `xbm', `xface', `cursor-font', `widget' and `font'. These keywords
|
|
|
2938 allow you to explicitly specify foreground and background colors.
|
|
|
2939 The argument should be anything acceptable to `make-color-instance'.
|
|
|
2940 This will cause what would be a `mono-pixmap' to instead be colorized
|
|
|
2941 as a two-color color-pixmap, and specifies the foreground and/or
|
|
|
2942 background colors for a pointer instead of black and white.)
|
|
|
2943 :mask-data
|
|
|
2944 (For `xbm' and `xface'. This specifies a mask to be used with the
|
|
|
2945 bitmap. The format is a list of width, height, and bits, like for
|
|
|
2946 :data.)
|
|
|
2947 :mask-file
|
|
|
2948 (For `xbm' and `xface'. This specifies a file containing the mask data.
|
|
|
2949 If neither a mask file nor inline mask data is given for an XBM image,
|
|
|
2950 and the XBM image comes from a file, XEmacs will look for a mask file
|
|
|
2951 with the same name as the image file but with "Mask" or "msk"
|
|
|
2952 appended. For example, if you specify the XBM file "left_ptr"
|
|
|
2953 [usually located in "/usr/include/X11/bitmaps"], the associated
|
|
|
2954 mask file "left_ptrmsk" will automatically be picked up.)
|
|
|
2955 :hotspot-x
|
|
|
2956 :hotspot-y
|
|
|
2957 (For `xbm' and `xface'. These keywords specify a hotspot if the image
|
|
|
2958 is instantiated as a `pointer'. Note that if the XBM image file
|
|
|
2959 specifies a hotspot, it will automatically be picked up if no
|
|
|
2960 explicit hotspot is given.)
|
|
|
2961 :color-symbols
|
|
|
2962 (Only for `xpm'. This specifies an alist that maps strings
|
|
|
2963 that specify symbolic color names to the actual color to be used
|
|
|
2964 for that symbolic color (in the form of a string or a color-specifier
|
|
|
2965 object). If this is not specified, the contents of `xpm-color-symbols'
|
|
|
2966 are used to generate the alist.)
|
|
|
2967 :face
|
|
|
2968 (Only for `inherit'. This specifies the face to inherit from.
|
|
|
2969 For widget glyphs this also specifies the face to use for
|
|
|
2970 display. It defaults to gui-element-face.)
|
|
|
2971
|
|
|
2972 Keywords accepted as menu item specs are also accepted by widget
|
|
|
2973 glyphs. These are `:selected', `:active', `:suffix', `:keys',
|
|
|
2974 `:style', `:filter', `:config', `:included', `:key-sequence',
|
|
|
2975 `:accelerator', `:label' and `:callback'.
|
|
|
2976
|
|
|
2977 If instead of a vector, the instantiator is a string, it will be
|
|
|
2978 converted into a vector by looking it up according to the specs in the
|
|
|
2979 `console-type-image-conversion-list' (q.v.) for the console type of
|
|
|
2980 the domain (usually a window; sometimes a frame or device) over which
|
|
|
2981 the image is being instantiated.
|
|
|
2982
|
|
|
2983 If the instantiator specifies data from a file, the data will be read
|
|
|
2984 in at the time that the instantiator is added to the image (which may
|
|
|
2985 be well before when the image is actually displayed), and the
|
|
|
2986 instantiator will be converted into one of the inline-data forms, with
|
|
|
2987 the filename retained using a :file keyword. This implies that the
|
|
|
2988 file must exist when the instantiator is added to the image, but does
|
|
|
2989 not need to exist at any other time (e.g. it may safely be a temporary
|
|
|
2990 file).

3786 redisplay. We have two caches - a per-window instance cache that

3787 keeps track of subwindows on a window, these are linked to their
|
|
|
3788 instantiator in the hashtable and when the instantiator goes away

3789 we want the instance to go away also. However we also have a

3790 per-frame instance cache that we use to determine if a subwindow is

3791 obscuring an area that we want to clear. We need to be able to flip

3792 through this quickly so a hashtable is not suitable hence the

3793 subwindow_cachels. The question is should we just not mark

3794 instances in the subwindow_cachels or should we try and invalidate

3795 the cache at suitable points in redisplay? If we don't invalidate
|

|
3796 the cache it will fill up with crud that will only get removed when

3797 the frame is deleted. So invalidation is good, the question is when

3798 and whether we mark as well. Go for the simple option - don't mark,
