|

990 Nothing is displayed.
|
|
|
991 'text
|
|
|
992 Displayed as text. The foreground and background colors and the
|
|
|
993 font of the text are specified independent of the pixmap. Typically
|
|
|
994 these attributes will come from the face of the surrounding text,
|
|
|
995 unless a face is specified for the glyph in which the image appears.
|
|
|
996 'mono-pixmap
|
|
|
997 Displayed as a mono pixmap (a pixmap with only two colors where the
|
|
|
998 foreground and background can be specified independent of the pixmap;
|
|
|
999 typically the pixmap assumes the foreground and background colors of
|
|
|
1000 the text around it, unless a face is specified for the glyph in which
|
|
|
1001 the image appears).
|
|

|
|
|
1003 Displayed as a color pixmap.

1004 'pointer
|
|
|
1005 Used as the mouse pointer for a window.
|
|
|
1006 'subwindow
|
|
|
1007 A child window that is treated as an image. This allows (e.g.)
|
|
|
1008 another program to be responsible for drawing into the window.

185

1012 are possible for a given instantiator, the "most natural" type
|

0
|
1013 for the instantiator's format is chosen. (For XBM, the most natural
|
|
|
1014 types are `mono-pixmap', followed by `color-pixmap', followed by
|
|
|
1015 `pointer'. For the other normal image formats, the most natural
|
|
|
1016 types are `color-pixmap', followed by `mono-pixmap', followed by
|
|
|
1017 `pointer'. For the string and formatted-string formats, the most
|
|
|
1018 natural types are `text', followed by `mono-pixmap' (not currently
|
|
|
1019 implemented), followed by `color-pixmap' (not currently implemented).
|
|
|
1020 The other formats can only be instantiated as one type. (If you
|
|
|
1021 want to control more specifically the order of the types into which
|
|
|
1022 an image is instantiated, just call `make-image-instance' repeatedly
|

1023 until it succeeds, passing less and less preferred destination types
|

1024 each time.
|

1026 If DEST-TYPES is omitted, all possible types are allowed.

|
|
|
1967 An image specifier is used for images (pixmaps and the like). It is used
|
|
|
1968 to describe the actual image in a glyph. It is instanced as an image-
|
|
|
1969 instance.
|
|
|
1970
|
|
|
1971 Image instantiators come in many formats: `xbm', `xpm', `gif', `jpeg',
|
|
|
1972 etc. This describes the format of the data describing the image. The
|
|
|
1973 resulting image instances also come in many types -- `mono-pixmap',
|
|
|
1974 `color-pixmap', `text', `pointer', etc. This refers to the behavior of
|
|
|
1975 the image and the sorts of places it can appear. (For example, a
|
|
|
1976 color-pixmap image has fixed colors specified for it, while a
|
|
185
|
1977 mono-pixmap image comes in two unspecified shades "foreground" and
|
|
|
1978 "background" that are determined from the face of the glyph or
|
|
0
|
1979 surrounding text; a text image appears as a string of text and has an
|
|
|
1980 unspecified foreground, background, and font; a pointer image behaves
|
|
|
1981 like a mono-pixmap image but can only be used as a mouse pointer
|
|
|
1982 \[mono-pixmap images cannot be used as mouse pointers]; etc.) It is
|
|
|
1983 important to keep the distinction between image instantiator format and
|
|
|
1984 image instance type in mind. Typically, a given image instantiator
|
|
|
1985 format can result in many different image instance types (for example,
|
|
|
1986 `xpm' can be instanced as `color-pixmap', `mono-pixmap', or `pointer';
|
|
|
1987 whereas `cursor-font' can be instanced only as `pointer'), and a
|
|
|
1988 particular image instance type can be generated by many different
|
|
|
1989 image instantiator formats (e.g. `color-pixmap' can be generated by `xpm',
|
|
|
1990 `gif', `jpeg', etc.).
|

|
2060 The valid keywords are:
|
|
|
2061
|
|
|
2062 :data
|
|
|
2063 (Inline data. For most formats above, this should be a string. For
|
|
|
2064 XBM images, this should be a list of three elements: width, height, and
|
|
|
2065 a string of bit data. This keyword is not valid for instantiator
|
|
|
2066 formats `nothing' and `inherit'.)
|
|
|
2067 :file
|
|
|
2068 (Data is contained in a file. The value is the name of this file.
|
|
|
2069 If both :data and :file are specified, the image is created from
|
|
|
2070 what is specified in :data and the string in :file becomes the
|
|
|
2071 value of the `image-instance-file-name' function when applied to
|
|
|
2072 the resulting image-instance. This keyword is not valid for
|
|
|
2073 instantiator formats `nothing', `string', `formatted-string',
|
|
122
|
2074 `cursor-font', `font', `autodetect', and `inherit'.)
|
|
0
|
2075 :foreground
|
|
|
2076 :background
|
|
|
2077 (For `xbm', `xface', `cursor-font', and `font'. These keywords
|
|
|
2078 allow you to explicitly specify foreground and background colors.
|
|
|
2079 The argument should be anything acceptable to `make-color-instance'.
|
|
|
2080 This will cause what would be a `mono-pixmap' to instead be colorized
|
|
|
2081 as a two-color color-pixmap, and specifies the foreground and/or
|
|
|
2082 background colors for a pointer instead of black and white.)
|
|
|
2083 :mask-data
|
|
|
2084 (For `xbm' and `xface'. This specifies a mask to be used with the
|
|
|
2085 bitmap. The format is a list of width, height, and bits, like for
|
|
|
2086 :data.)
|
|
|
2087 :mask-file
|
|
|
2088 (For `xbm' and `xface'. This specifies a file containing the mask data.
|
|
|
2089 If neither a mask file nor inline mask data is given for an XBM image,
|
|
|
2090 and the XBM image comes from a file, XEmacs will look for a mask file
|
|
185
|
2091 with the same name as the image file but with "Mask" or "msk"
|
|
|
2092 appended. For example, if you specify the XBM file "left_ptr"
|
|
|
2093 [usually located in "/usr/include/X11/bitmaps"], the associated
|
|
|
2094 mask file "left_ptrmsk" will automatically be picked up.)
|
|
0
|
2095 :hotspot-x
|
|
|
2096 :hotspot-y
|
|
|
2097 (For `xbm' and `xface'. These keywords specify a hotspot if the image
|
|
|
2098 is instantiated as a `pointer'. Note that if the XBM image file
|
|
|
2099 specifies a hotspot, it will automatically be picked up if no
|
|
|
2100 explicit hotspot is given.)
|
|
|
2101 :color-symbols
|
|
|
2102 (Only for `xpm'. This specifies an alist that maps strings
|
|
|
2103 that specify symbolic color names to the actual color to be used
|
|
|
2104 for that symbolic color (in the form of a string or a color-specifier
|
|
|
2105 object). If this is not specified, the contents of `xpm-color-symbols'
|
|
|
2106 are used to generate the alist.)
|
|
|
2107 :face
|
|
|
2108 (Only for `inherit'. This specifies the face to inherit from.)
|
|
|
2109
|
|
|
2110 If instead of a vector, the instantiator is a string, it will be
|
|
|
2111 converted into a vector by looking it up according to the specs in the
|
|
|
2112 `console-type-image-conversion-list' (q.v.) for the console type of
|
|
|
2113 the domain (usually a window; sometimes a frame or device) over which
|
|
|
2114 the image is being instantiated.
|
|
|
2115
|
|
|
2116 If the instantiator specifies data from a file, the data will be read
|
|
|
2117 in at the time that the instantiator is added to the image (which may
|
|
|
2118 be well before when the image is actually displayed), and the
|
|
|
2119 instantiator will be converted into one of the inline-data forms, with
|
|
|
2120 the filename retained using a :file keyword. This implies that the
|
|
|
2121 file must exist when the instantiator is added to the image, but does
|
|
|
2122 not need to exist at any other time (e.g. it may safely be a temporary
|
|
|
2123 file).
