|
1149 'nothing
|
|
|
1150 Nothing is displayed.
|
|
|
1151 'text
|
|
|
1152 Displayed as text. The foreground and background colors and the
|
|
|
1153 font of the text are specified independent of the pixmap. Typically
|
|
|
1154 these attributes will come from the face of the surrounding text,
|
|
|
1155 unless a face is specified for the glyph in which the image appears.
|
|
|
1156 'mono-pixmap
|
|
|
1157 Displayed as a mono pixmap (a pixmap with only two colors where the
|
|
|
1158 foreground and background can be specified independent of the pixmap;
|
|
|
1159 typically the pixmap assumes the foreground and background colors of
|
|
|
1160 the text around it, unless a face is specified for the glyph in which
|
|
|
1161 the image appears).
|
|
|
1162 'color-pixmap
|
|
|
1163 Displayed as a color pixmap.
|
|
|
1164 'pointer
|
|
|
1165 Used as the mouse pointer for a window.
|
|
|
1166 'subwindow
|
|
|
1167 A child window that is treated as an image. This allows (e.g.)
|
|
|
1168 another program to be responsible for drawing into the window.

|
|
|
1172 are possible for a given instantiator, the "most natural" type
|

|
1173 for the instantiator's format is chosen. (For XBM, the most natural
|
|
|
1174 types are `mono-pixmap', followed by `color-pixmap', followed by
|
|
|
1175 `pointer'. For the other normal image formats, the most natural
|
|
|
1176 types are `color-pixmap', followed by `mono-pixmap', followed by
|
|
|
1177 `pointer'. For the string and formatted-string formats, the most
|
|
|
1178 natural types are `text', followed by `mono-pixmap' (not currently
|
|
|
1179 implemented), followed by `color-pixmap' (not currently implemented).
|
|
|
1180 The other formats can only be instantiated as one type. (If you
|
|
|
1181 want to control more specifically the order of the types into which
|
|
|
1182 an image is instantiated, just call `make-image-instance' repeatedly
|

1184 each time.

2654
|
|
|
2655 An image specifier is used for images (pixmaps and the like). It is used
|
|
|
2656 to describe the actual image in a glyph. It is instanced as an image-
|
|
|
2657 instance.
|
|
|
2658
|
|
|
2659 Image instantiators come in many formats: `xbm', `xpm', `gif', `jpeg',
|
|
|
2660 etc. This describes the format of the data describing the image. The
|
|
|
2661 resulting image instances also come in many types -- `mono-pixmap',
|
|
|
2662 `color-pixmap', `text', `pointer', etc. This refers to the behavior of
|
|
|
2663 the image and the sorts of places it can appear. (For example, a
|
|
|
2664 color-pixmap image has fixed colors specified for it, while a
|
|
|
2665 mono-pixmap image comes in two unspecified shades "foreground" and
|
|
|
2666 "background" that are determined from the face of the glyph or
|
|
|
2667 surrounding text; a text image appears as a string of text and has an
|
|
|
2668 unspecified foreground, background, and font; a pointer image behaves
|
|
|
2669 like a mono-pixmap image but can only be used as a mouse pointer
|
|
|
2670 \[mono-pixmap images cannot be used as mouse pointers]; etc.) It is
|
|
|
2671 important to keep the distinction between image instantiator format and
|
|
|
2672 image instance type in mind. Typically, a given image instantiator
|
|
|
2673 format can result in many different image instance types (for example,
|
|
|
2674 `xpm' can be instanced as `color-pixmap', `mono-pixmap', or `pointer';
|
|
|
2675 whereas `cursor-font' can be instanced only as `pointer'), and a
|
|
|
2676 particular image instance type can be generated by many different
|
|
|
2677 image instantiator formats (e.g. `color-pixmap' can be generated by `xpm',
|
|
|
2678 `gif', `jpeg', etc.).

2680 See `make-image-instance' for a more detailed discussion of image
|
|
|
2681 instance types.
|
|
|
2682
|
|
|
2683 An image instantiator should be a string or a vector of the form
|
|
|
2684
|
|
|
2685 [FORMAT :KEYWORD VALUE ...]
|
|
|
2686
|
|
|
2687 i.e. a format symbol followed by zero or more alternating keyword-value
|
|
|
2688 pairs. FORMAT should be one of
|
|
|
2689
|
|
|
2690 'nothing
|
|
|
2691 (Don't display anything; no keywords are valid for this.
|
|
|
2692 Can only be instanced as `nothing'.)
|
|
|
2693 'string
|
|
|
2694 (Display this image as a text string. Can only be instanced
|
|
|
2695 as `text', although support for instancing as `mono-pixmap'
|
|
|
2696 should be added.)
|
|
|
2697 'formatted-string
|
|
|
2698 (Display this image as a text string, with replaceable fields;
|
|
|
2699 not currently implemented.)
|
|
|
2700 'xbm
|
|
|
2701 (An X bitmap; only if X or Windows support was compiled into this XEmacs.
|
|
|
2702 Can be instanced as `mono-pixmap', `color-pixmap', or `pointer'.)
|
|
|
2703 'xpm
|
|
|
2704 (An XPM pixmap; only if XPM support was compiled into this XEmacs.
|
|
|
2705 Can be instanced as `color-pixmap', `mono-pixmap', or `pointer'.)
|
|
|
2706 'xface
|
|
|
2707 (An X-Face bitmap, used to encode people's faces in e-mail messages;
|
|
|
2708 only if X-Face support was compiled into this XEmacs. Can be
|
|
|
2709 instanced as `mono-pixmap', `color-pixmap', or `pointer'.)
|
|
|
2710 'gif
|
|
|
2711 (A GIF87 or GIF89 image; only if GIF support was compiled into this
|
|
|
2712 XEmacs. NOTE: only the first frame of animated gifs will be displayed.
|
|
|
2713 Can be instanced as `color-pixmap'.)
|
|
|
2714 'jpeg
|
|
|
2715 (A JPEG image; only if JPEG support was compiled into this XEmacs.
|
|
|
2716 Can be instanced as `color-pixmap'.)
|
|
|
2717 'png
|
|
|
2718 (A PNG image; only if PNG support was compiled into this XEmacs.
|
|
|
2719 Can be instanced as `color-pixmap'.)
|
|
|
2720 'tiff
|
|
|
2721 (A TIFF image; only if TIFF support was compiled into this XEmacs.
|
|
|
2722 Can be instanced as `color-pixmap'.)
|
|
|
2723 'cursor-font
|
|
|
2724 (One of the standard cursor-font names, such as "watch" or
|
|
|
2725 "right_ptr" under X. Under X, this is, more specifically, any
|
|
|
2726 of the standard cursor names from appendix B of the Xlib manual
|
|
|
2727 [also known as the file <X11/cursorfont.h>] minus the XC_ prefix.
|
|
|
2728 On other window systems, the valid names will be specific to the
|
|
|
2729 type of window system. Can only be instanced as `pointer'.)
|
|
|
2730 'font
|
|
|
2731 (A glyph from a font; i.e. the name of a font, and glyph index into it
|
|
|
2732 of the form "FONT fontname index [[mask-font] mask-index]".
|
|
|
2733 Currently can only be instanced as `pointer', although this should
|
|
|
2734 probably be fixed.)
|
|
|
2735 'subwindow
|
|
|
2736 (An embedded X window; not currently implemented.)
|
|
|
2737 'widget
|
|
|
2738 (A widget control, for instance text field or radio button.)
|
|
|
2739 'autodetect
|
|
|
2740 (XEmacs tries to guess what format the data is in. If X support
|
|
|
2741 exists, the data string will be checked to see if it names a filename.
|
|
|
2742 If so, and this filename contains XBM or XPM data, the appropriate
|
|
|
2743 sort of pixmap or pointer will be created. [This includes picking up
|
|
|
2744 any specified hotspot or associated mask file.] Otherwise, if `pointer'
|
|
|
2745 is one of the allowable image-instance types and the string names a
|
|
|
2746 valid cursor-font name, the image will be created as a pointer.
|
|
|
2747 Otherwise, the image will be displayed as text. If no X support
|
|
|
2748 exists, the image will always be displayed as text.)
|
|
|
2749 'inherit
|
|
|
2750 Inherit from the background-pixmap property of a face.
|
|
|
2751
|
|
|
2752 The valid keywords are:
|
|
|
2753
|
|
|
2754 :data
|
|
|
2755 (Inline data. For most formats above, this should be a string. For
|
|
|
2756 XBM images, this should be a list of three elements: width, height, and
|
|
|
2757 a string of bit data. This keyword is not valid for instantiator
|
|
|
2758 formats `nothing' and `inherit'.)
|
|
|
2759 :file
|
|
|
2760 (Data is contained in a file. The value is the name of this file.
|
|
|
2761 If both :data and :file are specified, the image is created from
|
|
|
2762 what is specified in :data and the string in :file becomes the
|
|
|
2763 value of the `image-instance-file-name' function when applied to
|
|
|
2764 the resulting image-instance. This keyword is not valid for
|
|
|
2765 instantiator formats `nothing', `string', `formatted-string',
|
|
|
2766 `cursor-font', `font', `autodetect', and `inherit'.)
|
|
|
2767 :foreground
|
|
|
2768 :background
|
|
|
2769 (For `xbm', `xface', `cursor-font', `widget' and `font'. These keywords
|
|
|
2770 allow you to explicitly specify foreground and background colors.
|
|
|
2771 The argument should be anything acceptable to `make-color-instance'.
|
|
|
2772 This will cause what would be a `mono-pixmap' to instead be colorized
|
|
|
2773 as a two-color color-pixmap, and specifies the foreground and/or
|
|
|
2774 background colors for a pointer instead of black and white.)
|
|
|
2775 :mask-data
|
|
|
2776 (For `xbm' and `xface'. This specifies a mask to be used with the
|
|
|
2777 bitmap. The format is a list of width, height, and bits, like for
|
|
|
2778 :data.)
|
|
|
2779 :mask-file
|
|
|
2780 (For `xbm' and `xface'. This specifies a file containing the mask data.
|
|
|
2781 If neither a mask file nor inline mask data is given for an XBM image,
|
|
|
2782 and the XBM image comes from a file, XEmacs will look for a mask file
|
|
|
2783 with the same name as the image file but with "Mask" or "msk"
|
|
|
2784 appended. For example, if you specify the XBM file "left_ptr"
|
|
|
2785 [usually located in "/usr/include/X11/bitmaps"], the associated
|
|
|
2786 mask file "left_ptrmsk" will automatically be picked up.)
|
|
|
2787 :hotspot-x
|
|
|
2788 :hotspot-y
|
|
|
2789 (For `xbm' and `xface'. These keywords specify a hotspot if the image
|
|
|
2790 is instantiated as a `pointer'. Note that if the XBM image file
|
|
|
2791 specifies a hotspot, it will automatically be picked up if no
|
|
|
2792 explicit hotspot is given.)
|
|
|
2793 :color-symbols
|
|
|
2794 (Only for `xpm'. This specifies an alist that maps strings
|
|
|
2795 that specify symbolic color names to the actual color to be used
|
|
|
2796 for that symbolic color (in the form of a string or a color-specifier
|
|
|
2797 object). If this is not specified, the contents of `xpm-color-symbols'
|
|
|
2798 are used to generate the alist.)
|
|
|
2799 :face
|
|
|
2800 (Only for `inherit'. This specifies the face to inherit from.)
|
|
|
2801
|
|
|
2802 If instead of a vector, the instantiator is a string, it will be
|
|
|
2803 converted into a vector by looking it up according to the specs in the
|
|
|
2804 `console-type-image-conversion-list' (q.v.) for the console type of
|
|
|
2805 the domain (usually a window; sometimes a frame or device) over which
|
|
|
2806 the image is being instantiated.
|
|
|
2807
|
|
|
2808 If the instantiator specifies data from a file, the data will be read
|
|
|
2809 in at the time that the instantiator is added to the image (which may
|
|
|
2810 be well before when the image is actually displayed), and the
|
|
|
2811 instantiator will be converted into one of the inline-data forms, with
|
|
|
2812 the filename retained using a :file keyword. This implies that the
|
|
|
2813 file must exist when the instantiator is added to the image, but does
|
|
|
2814 not need to exist at any other time (e.g. it may safely be a temporary
|
|
|
2815 file).

384

3562 not display them. It is problematic deciding what to do in

3563 redisplay. We have two caches - a per-window instance cache that

3564 keeps track of subwindows on a window, these are linked to their

|
|
3565 instantiator in the hashtable and when the instantiator goes away

3566 we want the instance to go away also. However we also have a

3567 per-frame instance cache that we use to determine if a subwindow is

3568 obscuring an area that we want to clear. We need to be able to flip

3569 through this quickly so a hashtable is not suitable hence the

|
|
|
3573 the cache it will fill up with crud that will only get removed when

3574 the frame is deleted. So invalidation is good, the question is when
