1115 Image-instance objects encapsulate the way a particular image (pixmap,

|

1119 instances, if you want more control over the instantiation process.

|

1126
|
|
|
1127 'nothing
|
|
|
1128 Nothing is displayed.
|
|
|
1129 'text
|
|
|
1130 Displayed as text. The foreground and background colors and the
|
|
|
1131 font of the text are specified independent of the pixmap. Typically
|
|
|
1132 these attributes will come from the face of the surrounding text,
|
|
|
1133 unless a face is specified for the glyph in which the image appears.
|
|
|
1134 'mono-pixmap
|
|
|
1135 Displayed as a mono pixmap (a pixmap with only two colors where the
|
|
|
1136 foreground and background can be specified independent of the pixmap;
|
|
|
1137 typically the pixmap assumes the foreground and background colors of
|
|
|
1138 the text around it, unless a face is specified for the glyph in which
|
|
|
1139 the image appears).
|
|
|
1140 'color-pixmap
|
|
|
1141 Displayed as a color pixmap.
|
|
|
1142 'pointer
|
|
|
1143 Used as the mouse pointer for a window.
|
|
|
1144 'subwindow
|
|
|
1145 A child window that is treated as an image. This allows (e.g.)
|
|
|
1146 another program to be responsible for drawing into the window.
|
|
412
|
1147 Not currently implemented.

1149 The DEST-TYPES list is unordered. If multiple destination types
|
|
|
1150 are possible for a given instantiator, the "most natural" type
|
|
|
1151 for the instantiator's format is chosen. (For XBM, the most natural
|
|
|
1152 types are `mono-pixmap', followed by `color-pixmap', followed by
|
|
|
1153 `pointer'. For the other normal image formats, the most natural
|
|
|
1154 types are `color-pixmap', followed by `mono-pixmap', followed by
|
|
|
1155 `pointer'. For the string and formatted-string formats, the most
|
|
|
1156 natural types are `text', followed by `mono-pixmap' (not currently
|
|
|
1157 implemented), followed by `color-pixmap' (not currently implemented).
|
|
|
1158 The other formats can only be instantiated as one type. (If you
|
|
|
1159 want to control more specifically the order of the types into which
|
|
|
1160 an image is instantiated, just call `make-image-instance' repeatedly
|
|
|
1161 until it succeeds, passing less and less preferred destination types
|
|
|
1162 each time.

1164 If DEST-TYPES is omitted, all possible types are allowed.

|

1167 If nil, an error message is generated. If t, no messages are
|
|
|
1168 generated and this function returns nil. If anything else, a warning
|
|

1169 message is generated and this function returns nil.

2632
|
|
|
2633 An image specifier is used for images (pixmaps and the like). It is used
|
|
|
2634 to describe the actual image in a glyph. It is instanced as an image-
|
|
|
2635 instance.
|
|
|
2636
|
|
|
2637 Image instantiators come in many formats: `xbm', `xpm', `gif', `jpeg',
|
|
|
2638 etc. This describes the format of the data describing the image. The
|
|
|
2639 resulting image instances also come in many types -- `mono-pixmap',
|
|
|
2640 `color-pixmap', `text', `pointer', etc. This refers to the behavior of
|
|
|
2641 the image and the sorts of places it can appear. (For example, a
|
|
|
2642 color-pixmap image has fixed colors specified for it, while a
|
|
|
2643 mono-pixmap image comes in two unspecified shades "foreground" and
|
|
|
2644 "background" that are determined from the face of the glyph or
|
|
|
2645 surrounding text; a text image appears as a string of text and has an
|
|
|
2646 unspecified foreground, background, and font; a pointer image behaves
|
|
|
2647 like a mono-pixmap image but can only be used as a mouse pointer
|
|
|
2648 \[mono-pixmap images cannot be used as mouse pointers]; etc.) It is
|
|
|
2649 important to keep the distinction between image instantiator format and
|
|
|
2650 image instance type in mind. Typically, a given image instantiator
|
|
|
2651 format can result in many different image instance types (for example,
|
|
|
2652 `xpm' can be instanced as `color-pixmap', `mono-pixmap', or `pointer';
|
|
|
2653 whereas `cursor-font' can be instanced only as `pointer'), and a
|
|
|
2654 particular image instance type can be generated by many different
|
|
|
2655 image instantiator formats (e.g. `color-pixmap' can be generated by `xpm',
|
|
|
2656 `gif', `jpeg', etc.).
|
|
|
2657
|
|
|
2658 See `make-image-instance' for a more detailed discussion of image
|
|
|
2659 instance types.

2661 An image instantiator should be a string or a vector of the form

|
|

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

384

3535 not display them. It is problematic deciding what to do in

3536 redisplay. We have two caches - a per-window instance cache that

3537 keeps track of subwindows on a window, these are linked to their
|
|
|
3538 instantiator in the hashtable and when the instantiator goes away

3539 we want the instance to go away also. However we also have a

3540 per-frame instance cache that we use to determine if a subwindow is

3541 obscuring an area that we want to clear. We need to be able to flip

3542 through this quickly so a hashtable is not suitable hence the

412

3543 subwindow_cachels. The question is should we just not mark

3544 instances in the subwindow_cachelsnor should we try and invalidate

3545 the cache at suitable points in redisplay? If we don't invalidate
|
|
|
3546 the cache it will fill up with crud that will only get removed when

3547 the frame is deleted. So invalidation is good, the question is when
