|
|
|
981 'text
|
|
|
982 Displayed as text. The foreground and background colors and the
|
|
|
983 font of the text are specified independent of the pixmap. Typically
|
|
|
984 these attributes will come from the face of the surrounding text,
|
|
|
985 unless a face is specified for the glyph in which the image appears.
|
|
|
986 'mono-pixmap
|
|
|
987 Displayed as a mono pixmap (a pixmap with only two colors where the
|
|
|
988 foreground and background can be specified independent of the pixmap;
|
|
|
989 typically the pixmap assumes the foreground and background colors of
|
|
|
990 the text around it, unless a face is specified for the glyph in which
|

991 the image appears).
|
|
|
992 'color-pixmap
|
|

993 Displayed as a color pixmap.

994 'pointer
|
|
|
995 Used as the mouse pointer for a window.
|
|
|
996 'subwindow
|
|
|
997 A child window that is treated as an image. This allows (e.g.)
|
|
|
998 another program to be responsible for drawing into the window.

185
|
1002 are possible for a given instantiator, the "most natural" type
|
|
0
|
1003 for the instantiator's format is chosen. (For XBM, the most natural
|
|
|
1004 types are `mono-pixmap', followed by `color-pixmap', followed by
|
|
|
1005 `pointer'. For the other normal image formats, the most natural
|
|
|
1006 types are `color-pixmap', followed by `mono-pixmap', followed by
|
|
|
1007 `pointer'. For the string and formatted-string formats, the most
|
|
|
1008 natural types are `text', followed by `mono-pixmap' (not currently
|
|
|
1009 implemented), followed by `color-pixmap' (not currently implemented).
|
|
|
1010 The other formats can only be instantiated as one type. (If you
|
|
|
1011 want to control more specifically the order of the types into which
|
|
|
1012 an image is instantiated, just call `make-image-instance' repeatedly
|

1014 each time.

1016 If DEST-TYPES is omitted, all possible types are allowed.

2062 An image specifier is used for images (pixmaps and the like). It is used
|
|
|
2063 to describe the actual image in a glyph. It is instanced as an image-
|
|
|
2064 instance.
|
|
|
2065
|
|
|
2066 Image instantiators come in many formats: `xbm', `xpm', `gif', `jpeg',
|
|
|
2067 etc. This describes the format of the data describing the image. The
|
|
|
2068 resulting image instances also come in many types -- `mono-pixmap',
|
|
|
2069 `color-pixmap', `text', `pointer', etc. This refers to the behavior of
|
|
|
2070 the image and the sorts of places it can appear. (For example, a
|
|
|
2071 color-pixmap image has fixed colors specified for it, while a
|
|
185
|
2072 mono-pixmap image comes in two unspecified shades "foreground" and
|
|
|
2073 "background" that are determined from the face of the glyph or
|
|
0
|
2074 surrounding text; a text image appears as a string of text and has an
|
|
|
2075 unspecified foreground, background, and font; a pointer image behaves

|
|
2076 like a mono-pixmap image but can only be used as a mouse pointer
|
|
|
2077 \[mono-pixmap images cannot be used as mouse pointers]; etc.) It is
|
|
|
2078 important to keep the distinction between image instantiator format and
|
|
|
2079 image instance type in mind. Typically, a given image instantiator
|
|
|
2080 format can result in many different image instance types (for example,
|
|
|
2081 `xpm' can be instanced as `color-pixmap', `mono-pixmap', or `pointer';
|
|
|
2082 whereas `cursor-font' can be instanced only as `pointer'), and a
|
|
|
2083 particular image instance type can be generated by many different
|
|
|
2084 image instantiator formats (e.g. `color-pixmap' can be generated by `xpm',
|
|
|
2085 `gif', `jpeg', etc.).
|
|
|
2086
|
|
|
2087 See `make-image-instance' for a more detailed discussion of image
|
|
|
2088 instance types.
|
|
|
2089
|
|
|
2090 An image instantiator should be a string or a vector of the form
|
|
|
2091
|
|
|
2092 [FORMAT :KEYWORD VALUE ...]
|
|
|
2093
|
|
|
2094 i.e. a format symbol followed by zero or more alternating keyword-value
|
|
|
2095 pairs. FORMAT should be one of
|
|
|
2096
|
|
|
2097 'nothing
|
|
|
2098 (Don't display anything; no keywords are valid for this.
|
|
|
2099 Can only be instanced as `nothing'.)
|
|
|
2100 'string
|
|
|
2101 (Display this image as a text string. Can only be instanced
|
|
|
2102 as `text', although support for instancing as `mono-pixmap'
|
|
|
2103 should be added.)
|
|
|
2104 'formatted-string
|
|
|
2105 (Display this image as a text string, with replaceable fields;
|
|
|
2106 not currently implemented.)
|
|
|
2107 'xbm
|
|
|
2108 (An X bitmap; only if X support was compiled into this XEmacs.
|
|
|
2109 Can be instanced as `mono-pixmap', `color-pixmap', or `pointer'.)
|
|
|
2110 'xpm
|
|
|
2111 (An XPM pixmap; only if XPM support was compiled into this XEmacs.
|
|
|
2112 Can be instanced as `color-pixmap', `mono-pixmap', or `pointer'.)
|
|
|
2113 'xface
|
|
|
2114 (An X-Face bitmap, used to encode people's faces in e-mail messages;
|
|
|
2115 only if X-Face support was compiled into this XEmacs. Can be
|
|
|
2116 instanced as `mono-pixmap', `color-pixmap', or `pointer'.)
|
|
|
2117 'gif
|
|
|
2118 (A GIF87 or GIF89 image; only if GIF support was compiled into this
|
|
|
2119 XEmacs. Can be instanced as `color-pixmap'.)
|
|
|
2120 'jpeg
|
|
|
2121 (A JPEG image; only if JPEG support was compiled into this XEmacs.
|
|
|
2122 Can be instanced as `color-pixmap'.)
|
|
|
2123 'png
|
|
|
2124 (A PNG/GIF24 image; only if PNG support was compiled into this XEmacs.
|
|
|
2125 Can be instanced as `color-pixmap'.)
|
|
|
2126 'tiff
|
|
|
2127 (A TIFF image; not currently implemented.)
|
|
|
2128 'cursor-font
|
|
185
|
2129 (One of the standard cursor-font names, such as "watch" or
|
|
|
2130 "right_ptr" under X. Under X, this is, more specifically, any
|
|
0
|
2131 of the standard cursor names from appendix B of the Xlib manual
|
|
|
2132 [also known as the file <X11/cursorfont.h>] minus the XC_ prefix.
|
|
|
2133 On other window systems, the valid names will be specific to the
|
|
|
2134 type of window system. Can only be instanced as `pointer'.)
|
|
|
2135 'font
|
|
|
2136 (A glyph from a font; i.e. the name of a font, and glyph index into it
|
|
185
|
2137 of the form "FONT fontname index [[mask-font] mask-index]".
|
|
0
|
2138 Currently can only be instanced as `pointer', although this should
|
|
|
2139 probably be fixed.)
|
|
|
2140 'subwindow
|
|
|
2141 (An embedded X window; not currently implemented.)
|
|
122
|
2142 'autodetect
|
|
0
|
2143 (XEmacs tries to guess what format the data is in. If X support
|
|
|
2144 exists, the data string will be checked to see if it names a filename.
|
|
|
2145 If so, and this filename contains XBM or XPM data, the appropriate
|
|
|
2146 sort of pixmap or pointer will be created. [This includes picking up
|
|
|
2147 any specified hotspot or associated mask file.] Otherwise, if `pointer'
|
|
|
2148 is one of the allowable image-instance types and the string names a
|
|
|
2149 valid cursor-font name, the image will be created as a pointer.
|
|
|
2150 Otherwise, the image will be displayed as text. If no X support
|
|
|
2151 exists, the image will always be displayed as text.)
|
|
|
2152 'inherit
|
|
|
2153 Inherit from the background-pixmap property of a face.
|
|
|
2154
|
|
|
2155 The valid keywords are:
|
|
|
2156
|
|
|
2157 :data
|
|
|
2158 (Inline data. For most formats above, this should be a string. For
|
|
|
2159 XBM images, this should be a list of three elements: width, height, and
|
|
|
2160 a string of bit data. This keyword is not valid for instantiator
|
|
|
2161 formats `nothing' and `inherit'.)
|
|
|
2162 :file
|
|
|
2163 (Data is contained in a file. The value is the name of this file.
|
|
|
2164 If both :data and :file are specified, the image is created from
|
|
|
2165 what is specified in :data and the string in :file becomes the
|
|
|
2166 value of the `image-instance-file-name' function when applied to
|
|
|
2167 the resulting image-instance. This keyword is not valid for
|
|
|
2168 instantiator formats `nothing', `string', `formatted-string',
|
|
122
|
2169 `cursor-font', `font', `autodetect', and `inherit'.)
|
|
0
|
2170 :foreground
|
|
|
2171 :background
|
|
|
2172 (For `xbm', `xface', `cursor-font', and `font'. These keywords
|
|
|
2173 allow you to explicitly specify foreground and background colors.
|
|
|
2174 The argument should be anything acceptable to `make-color-instance'.
|
|
|
2175 This will cause what would be a `mono-pixmap' to instead be colorized
|
|
|
2176 as a two-color color-pixmap, and specifies the foreground and/or
|
|
|
2177 background colors for a pointer instead of black and white.)
|
|
|
2178 :mask-data
|
|
|
2179 (For `xbm' and `xface'. This specifies a mask to be used with the
|
|
|
2180 bitmap. The format is a list of width, height, and bits, like for
|
|
|
2181 :data.)
|
|
|
2182 :mask-file
|
|
|
2183 (For `xbm' and `xface'. This specifies a file containing the mask data.
|
|
|
2184 If neither a mask file nor inline mask data is given for an XBM image,
|
|
|
2185 and the XBM image comes from a file, XEmacs will look for a mask file
|
|
185
|
2186 with the same name as the image file but with "Mask" or "msk"
|
|
|
2187 appended. For example, if you specify the XBM file "left_ptr"
|
|
|
2188 [usually located in "/usr/include/X11/bitmaps"], the associated
|
|
|
2189 mask file "left_ptrmsk" will automatically be picked up.)
|
|
0
|
2190 :hotspot-x
|
|
|
2191 :hotspot-y
|
|
|
2192 (For `xbm' and `xface'. These keywords specify a hotspot if the image
|
|
|
2193 is instantiated as a `pointer'. Note that if the XBM image file
|
|
|
2194 specifies a hotspot, it will automatically be picked up if no
|
|
|
2195 explicit hotspot is given.)
|
|
|
2196 :color-symbols
|
|
|
2197 (Only for `xpm'. This specifies an alist that maps strings
|
|
|
2198 that specify symbolic color names to the actual color to be used
|
|
|
2199 for that symbolic color (in the form of a string or a color-specifier
|
|
|
2200 object). If this is not specified, the contents of `xpm-color-symbols'
|
|
|
2201 are used to generate the alist.)
|
|
|
2202 :face
|
|
|
2203 (Only for `inherit'. This specifies the face to inherit from.)
|
|
|
2204
|
|
|
2205 If instead of a vector, the instantiator is a string, it will be
|
|
|
2206 converted into a vector by looking it up according to the specs in the
|
|
|
2207 `console-type-image-conversion-list' (q.v.) for the console type of
|
|
|
2208 the domain (usually a window; sometimes a frame or device) over which
|
|
|
2209 the image is being instantiated.
|
|
|
2210
|
|
|
2211 If the instantiator specifies data from a file, the data will be read
|
|
|
2212 in at the time that the instantiator is added to the image (which may
|
|
|
2213 be well before when the image is actually displayed), and the
|
|
|
2214 instantiator will be converted into one of the inline-data forms, with
|
|
|
2215 the filename retained using a :file keyword. This implies that the
|
|
|
2216 file must exist when the instantiator is added to the image, but does
|
|
|
2217 not need to exist at any other time (e.g. it may safely be a temporary
|
|
|
2218 file).
