|
|
|
1004 Nothing is displayed.
|
|
|
1005 'text
|
|
|
1006 Displayed as text. The foreground and background colors and the
|
|
|
1007 font of the text are specified independent of the pixmap. Typically
|
|
|
1008 these attributes will come from the face of the surrounding text,
|
|
|
1009 unless a face is specified for the glyph in which the image appears.
|
|
|
1010 'mono-pixmap
|
|
|
1011 Displayed as a mono pixmap (a pixmap with only two colors where the
|
|
|
1012 foreground and background can be specified independent of the pixmap;
|
|
|
1013 typically the pixmap assumes the foreground and background colors of
|
|
|
1014 the text around it, unless a face is specified for the glyph in which
|
|
|
1015 the image appears).
|
|

|
|

1017 Displayed as a color pixmap.

|
1019 Used as the mouse pointer for a window.
|
|
|
1020 'subwindow
|
|
|
1021 A child window that is treated as an image. This allows (e.g.)
|

|
1022 another program to be responsible for drawing into the window.

|

|
1026 are possible for a given instantiator, the \"most natural\" type
|
|
|
1027 for the instantiator's format is chosen. (For XBM, the most natural
|
|
|
1028 types are `mono-pixmap', followed by `color-pixmap', followed by
|
|
|
1029 `pointer'. For the other normal image formats, the most natural
|
|
|
1030 types are `color-pixmap', followed by `mono-pixmap', followed by
|
|
|
1031 `pointer'. For the string and formatted-string formats, the most
|
|
|
1032 natural types are `text', followed by `mono-pixmap' (not currently
|
|
|
1033 implemented), followed by `color-pixmap' (not currently implemented).
|
|
|
1034 The other formats can only be instantiated as one type. (If you
|
|
|
1035 want to control more specifically the order of the types into which
|
|
|
1036 an image is instantiated, just call `make-image-instance' repeatedly
|

1038 each time.

1040 If DEST-TYPES is omitted, all possible types are allowed.

|
|
|
1761 Image instantiators come in many formats: `xbm', `xpm', `gif', `jpeg',
|
|
|
1762 etc. This describes the format of the data describing the image. The
|
|
|
1763 resulting image instances also come in many types -- `mono-pixmap',
|
|
|
1764 `color-pixmap', `text', `pointer', etc. This refers to the behavior of
|
|
|
1765 the image and the sorts of places it can appear. (For example, a
|
|
|
1766 color-pixmap image has fixed colors specified for it, while a
|
|
|
1767 mono-pixmap image comes in two unspecified shades \"foreground\" and
|
|
|
1768 \"background\" that are determined from the face of the glyph or
|
|
|
1769 surrounding text; a text image appears as a string of text and has an
|
|
|
1770 unspecified foreground, background, and font; a pointer image behaves
|
|
|
1771 like a mono-pixmap image but can only be used as a mouse pointer
|
|
|
1772 \[mono-pixmap images cannot be used as mouse pointers]; etc.) It is
|
|
|
1773 important to keep the distinction between image instantiator format and
|
|
|
1774 image instance type in mind. Typically, a given image instantiator
|
|
|
1775 format can result in many different image instance types (for example,
|
|
|
1776 `xpm' can be instanced as `color-pixmap', `mono-pixmap', or `pointer';
|
|
|
1777 whereas `cursor-font' can be instanced only as `pointer'), and a
|
|
|
1778 particular image instance type can be generated by many different
|
|
|
1779 image instantiator formats (e.g. `color-pixmap' can be generated by `xpm',
|
|
|
1780 `gif', `jpeg', etc.).
|
|
|
1781
|
|
|
1782 See `make-image-instance' for a more detailed discussion of image
|
|
|
1783 instance types.
|
|
|
1784
|
|
|
1785 An image instantiator should be a string or a vector of the form
|
|
|
1786
|
|
|
1787 [FORMAT :KEYWORD VALUE ...]
|
|
|
1788
|
|
|
1789 i.e. a format symbol followed by zero or more alternating keyword-value
|
|
|
1790 pairs. FORMAT should be one of
|
|
|
1791
|
|
|
1792 'nothing
|
|
|
1793 (Don't display anything; no keywords are valid for this.
|
|
|
1794 Can only be instanced as `nothing'.)
|
|
|
1795 'string
|
|
|
1796 (Display this image as a text string. Can only be instanced
|
|
|
1797 as `text', although support for instancing as `mono-pixmap'
|
|
|
1798 should be added.)
|
|
|
1799 'formatted-string
|
|
|
1800 (Display this image as a text string, with replaceable fields;
|
|
|
1801 not currently implemented.)
|
|
|
1802 'xbm
|
|
|
1803 (An X bitmap; only if X support was compiled into this XEmacs.
|
|
|
1804 Can be instanced as `mono-pixmap', `color-pixmap', or `pointer'.)
|
|
|
1805 'xpm
|
|
|
1806 (An XPM pixmap; only if XPM support was compiled into this XEmacs.
|
|
|
1807 Can be instanced as `color-pixmap', `mono-pixmap', or `pointer'.)
|
|
|
1808 'xface
|
|
|
1809 (An X-Face bitmap, used to encode people's faces in e-mail messages;
|
|
|
1810 only if X-Face support was compiled into this XEmacs. Can be
|
|
|
1811 instanced as `mono-pixmap', `color-pixmap', or `pointer'.)
|
|
|
1812 'gif
|
|
|
1813 (A GIF87 or GIF89 image; only if GIF support was compiled into this
|
|
|
1814 XEmacs. Can be instanced as `color-pixmap'.)
|
|
|
1815 'jpeg
|
|
|
1816 (A JPEG image; only if JPEG support was compiled into this XEmacs.
|
|
|
1817 Can be instanced as `color-pixmap'.)
|
|
|
1818 'png
|
|
|
1819 (A PNG/GIF24 image; only if PNG support was compiled into this XEmacs.
|
|
|
1820 Can be instanced as `color-pixmap'.)
|
|
|
1821 'tiff
|
|
|
1822 (A TIFF image; not currently implemented.)
|
|
|
1823 'cursor-font
|
|
|
1824 (One of the standard cursor-font names, such as \"watch\" or
|
|
|
1825 \"right_ptr\" under X. Under X, this is, more specifically, any
|
|
|
1826 of the standard cursor names from appendix B of the Xlib manual
|
|
|
1827 [also known as the file <X11/cursorfont.h>] minus the XC_ prefix.
|
|
|
1828 On other window systems, the valid names will be specific to the
|
|
|
1829 type of window system. Can only be instanced as `pointer'.)
|
|
|
1830 'font
|
|
|
1831 (A glyph from a font; i.e. the name of a font, and glyph index into it
|
|
|
1832 of the form \"FONT fontname index [[mask-font] mask-index]\".
|
|
|
1833 Currently can only be instanced as `pointer', although this should
|
|
|
1834 probably be fixed.)
|
|
|
1835 'subwindow
|
|
|
1836 (An embedded X window; not currently implemented.)
|
|
|
1837 'autodetect
|
|
|
1838 (XEmacs tries to guess what format the data is in. If X support
|
|
|
1839 exists, the data string will be checked to see if it names a filename.
|
|
|
1840 If so, and this filename contains XBM or XPM data, the appropriate
|
|
|
1841 sort of pixmap or pointer will be created. [This includes picking up
|
|
|
1842 any specified hotspot or associated mask file.] Otherwise, if `pointer'
|
|
|
1843 is one of the allowable image-instance types and the string names a
|
|
|
1844 valid cursor-font name, the image will be created as a pointer.
|
|
|
1845 Otherwise, the image will be displayed as text. If no X support
|
|
|
1846 exists, the image will always be displayed as text.)
|
|
|
1847 'inherit
|
|
|
1848 Inherit from the background-pixmap property of a face.
|
|
|
1849
|
|
|
1850 The valid keywords are:
|
|
|
1851
|
|
|
1852 :data
|
|
|
1853 (Inline data. For most formats above, this should be a string. For
|
|
|
1854 XBM images, this should be a list of three elements: width, height, and
|
|
|
1855 a string of bit data. This keyword is not valid for instantiator
|
|
|
1856 formats `nothing' and `inherit'.)
|
|
|
1857 :file
|
|
|
1858 (Data is contained in a file. The value is the name of this file.
|
|
|
1859 If both :data and :file are specified, the image is created from
|
|
|
1860 what is specified in :data and the string in :file becomes the
|
|
|
1861 value of the `image-instance-file-name' function when applied to
|
|
|
1862 the resulting image-instance. This keyword is not valid for
|
|
|
1863 instantiator formats `nothing', `string', `formatted-string',
|
|
|
1864 `cursor-font', `font', `autodetect', and `inherit'.)
|
|
|
1865 :foreground
|
|
|
1866 :background
|
|
|
1867 (For `xbm', `xface', `cursor-font', and `font'. These keywords
|
|
|
1868 allow you to explicitly specify foreground and background colors.
|
|
|
1869 The argument should be anything acceptable to `make-color-instance'.
|
|
|
1870 This will cause what would be a `mono-pixmap' to instead be colorized
|
|
|
1871 as a two-color color-pixmap, and specifies the foreground and/or
|
|
|
1872 background colors for a pointer instead of black and white.)
|
|
|
1873 :mask-data
|
|
|
1874 (For `xbm' and `xface'. This specifies a mask to be used with the
|
|
|
1875 bitmap. The format is a list of width, height, and bits, like for
|
|
|
1876 :data.)
|
|
|
1877 :mask-file
|
|
|
1878 (For `xbm' and `xface'. This specifies a file containing the mask data.
|
|
|
1879 If neither a mask file nor inline mask data is given for an XBM image,
|
|
|
1880 and the XBM image comes from a file, XEmacs will look for a mask file
|
|
|
1881 with the same name as the image file but with \"Mask\" or \"msk\"
|
|
|
1882 appended. For example, if you specify the XBM file \"left_ptr\"
|
|
|
1883 [usually located in \"/usr/include/X11/bitmaps\"], the associated
|
|
|
1884 mask file \"left_ptrmsk\" will automatically be picked up.)
|
|
|
1885 :hotspot-x
|
|
|
1886 :hotspot-y
|
|
|
1887 (For `xbm' and `xface'. These keywords specify a hotspot if the image
|
|
|
1888 is instantiated as a `pointer'. Note that if the XBM image file
|
|
|
1889 specifies a hotspot, it will automatically be picked up if no
|
|
|
1890 explicit hotspot is given.)
|
|
|
1891 :color-symbols
|
|
|
1892 (Only for `xpm'. This specifies an alist that maps strings
|
|
|
1893 that specify symbolic color names to the actual color to be used
|
|
|
1894 for that symbolic color (in the form of a string or a color-specifier
|
|
|
1895 object). If this is not specified, the contents of `xpm-color-symbols'
|
|
|
1896 are used to generate the alist.)
|
|
|
1897 :face
|
|
|
1898 (Only for `inherit'. This specifies the face to inherit from.)
|
|
|
1899
|
|
|
1900 If instead of a vector, the instantiator is a string, it will be
|
|
|
1901 converted into a vector by looking it up according to the specs in the
|
|
|
1902 `console-type-image-conversion-list' (q.v.) for the console type of
|
|
|
1903 the domain (usually a window; sometimes a frame or device) over which
|
|
|
1904 the image is being instantiated.
|
|
|
1905
|
|
|
1906 If the instantiator specifies data from a file, the data will be read
|
|
|
1907 in at the time that the instantiator is added to the image (which may
|
|
|
1908 be well before when the image is actually displayed), and the
|
|
|
1909 instantiator will be converted into one of the inline-data forms, with
|
|
|
1910 the filename retained using a :file keyword. This implies that the
|
|
|
1911 file must exist when the instantiator is added to the image, but does
|
|
|
1912 not need to exist at any other time (e.g. it may safely be a temporary
|
|
|
1913 file).
