|
|
|
1007 Nothing is displayed.
|
|
|
1008 'text
|
|
|
1009 Displayed as text. The foreground and background colors and the
|
|
|
1010 font of the text are specified independent of the pixmap. Typically
|
|
|
1011 these attributes will come from the face of the surrounding text,
|
|
|
1012 unless a face is specified for the glyph in which the image appears.
|
|
|
1013 'mono-pixmap
|
|
|
1014 Displayed as a mono pixmap (a pixmap with only two colors where the
|
|
|
1015 foreground and background can be specified independent of the pixmap;
|
|
|
1016 typically the pixmap assumes the foreground and background colors of
|
|
|
1017 the text around it, unless a face is specified for the glyph in which
|
|
|
1018 the image appears).
|
|
|
1019 'color-pixmap
|
|
|
1020 Displayed as a color pixmap.
|
|
|
1021 'pointer
|
|
|
1022 Used as the mouse pointer for a window.
|
|
|
1023 'subwindow
|
|
|
1024 A child window that is treated as an image. This allows (e.g.)
|
|
|
1025 another program to be responsible for drawing into the window.

1028 The DEST-TYPES list is unordered. If multiple destination types
|
|
|
1029 are possible for a given instantiator, the \"most natural\" type
|
|
|
1030 for the instantiator's format is chosen. (For XBM, the most natural
|
|
|
1031 types are `mono-pixmap', followed by `color-pixmap', followed by
|
|
|
1032 `pointer'. For the other normal image formats, the most natural
|
|
|
1033 types are `color-pixmap', followed by `mono-pixmap', followed by
|
|
|
1034 `pointer'. For the string and formatted-string formats, the most
|
|
|
1035 natural types are `text', followed by `mono-pixmap' (not currently
|
|
|
1036 implemented), followed by `color-pixmap' (not currently implemented).
|
|
|
1037 The other formats can only be instantiated as one type. (If you
|
|
|
1038 want to control more specifically the order of the types into which
|
|
|
1039 an image is instantiated, just call `make-image-instance' repeatedly
|

1040 until it succeeds, passing less and less preferred destination types
|
|
|
1041 each time.
|

1043 If DEST-TYPES is omitted, all possible types are allowed.

1044

1045 NO-ERROR controls what happens when the image cannot be generated.
|

1047 generated and this function returns nil. If anything else, a warning

1048 message is generated and this function returns nil.

1760
|
|
|
1761 An image specifier is used for images (pixmaps and the like). It is used
|
|
|
1762 to describe the actual image in a glyph. It is instanced as an image-
|
|
|
1763 instance.
|
|
|
1764
|
|
|
1765 Image instantiators come in many formats: `xbm', `xpm', `gif', `jpeg',
|
|
|
1766 etc. This describes the format of the data describing the image. The
|
|
|
1767 resulting image instances also come in many types -- `mono-pixmap',
|
|
|
1768 `color-pixmap', `text', `pointer', etc. This refers to the behavior of
|
|
|
1769 the image and the sorts of places it can appear. (For example, a
|
|
|
1770 color-pixmap image has fixed colors specified for it, while a
|
|
|
1771 mono-pixmap image comes in two unspecified shades \"foreground\" and
|
|
|
1772 \"background\" that are determined from the face of the glyph or
|
|
|
1773 surrounding text; a text image appears as a string of text and has an
|
|
|
1774 unspecified foreground, background, and font; a pointer image behaves
|
|
|
1775 like a mono-pixmap image but can only be used as a mouse pointer
|
|
|
1776 \[mono-pixmap images cannot be used as mouse pointers]; etc.) It is
|
|
|
1777 important to keep the distinction between image instantiator format and
|
|
|
1778 image instance type in mind. Typically, a given image instantiator
|
|
|
1779 format can result in many different image instance types (for example,
|
|
|
1780 `xpm' can be instanced as `color-pixmap', `mono-pixmap', or `pointer';
|
|
|
1781 whereas `cursor-font' can be instanced only as `pointer'), and a
|
|
|
1782 particular image instance type can be generated by many different
|
|
|
1783 image instantiator formats (e.g. `color-pixmap' can be generated by `xpm',
|
|
|
1784 `gif', `jpeg', etc.).
|
|
|
1785
|
|
|
1786 See `make-image-instance' for a more detailed discussion of image
|
|
|
1787 instance types.
|
|
|
1788
|
|
|
1789 An image instantiator should be a string or a vector of the form
|
|
|
1790
|
|
|
1791 [FORMAT :KEYWORD VALUE ...]
|
|
|
1792
|
|
|
1793 i.e. a format symbol followed by zero or more alternating keyword-value
|
|
|
1794 pairs. FORMAT should be one of
|
|
|
1795
|
|
|
1796 'nothing
|
|
|
1797 (Don't display anything; no keywords are valid for this.
|
|
|
1798 Can only be instanced as `nothing'.)
|
|
|
1799 'string
|
|
|
1800 (Display this image as a text string. Can only be instanced
|
|
|
1801 as `text', although support for instancing as `mono-pixmap'
|
|
|
1802 should be added.)
|
|
|
1803 'formatted-string
|
|
|
1804 (Display this image as a text string, with replaceable fields;
|
|
|
1805 not currently implemented.)
|
|
|
1806 'xbm
|
|
|
1807 (An X bitmap; only if X support was compiled into this XEmacs.
|
|
|
1808 Can be instanced as `mono-pixmap', `color-pixmap', or `pointer'.)
|
|
|
1809 'xpm
|
|
|
1810 (An XPM pixmap; only if XPM support was compiled into this XEmacs.
|
|
|
1811 Can be instanced as `color-pixmap', `mono-pixmap', or `pointer'.)
|
|
|
1812 'xface
|
|
|
1813 (An X-Face bitmap, used to encode people's faces in e-mail messages;
|
|
|
1814 only if X-Face support was compiled into this XEmacs. Can be
|
|
|
1815 instanced as `mono-pixmap', `color-pixmap', or `pointer'.)
|
|
|
1816 'gif
|
|
|
1817 (A GIF87 or GIF89 image; only if GIF support was compiled into this
|
|
|
1818 XEmacs. Can be instanced as `color-pixmap'.)
|
|
|
1819 'jpeg
|
|
|
1820 (A JPEG image; only if JPEG support was compiled into this XEmacs.
|
|
|
1821 Can be instanced as `color-pixmap'.)
|
|
|
1822 'png
|
|
|
1823 (A PNG/GIF24 image; only if PNG support was compiled into this XEmacs.
|
|
|
1824 Can be instanced as `color-pixmap'.)
|
|
|
1825 'tiff
|
|
|
1826 (A TIFF image; not currently implemented.)
|
|
|
1827 'cursor-font
|
|
|
1828 (One of the standard cursor-font names, such as \"watch\" or
|
|
|
1829 \"right_ptr\" under X. Under X, this is, more specifically, any
|
|
|
1830 of the standard cursor names from appendix B of the Xlib manual
|
|
|
1831 [also known as the file <X11/cursorfont.h>] minus the XC_ prefix.
|
|
|
1832 On other window systems, the valid names will be specific to the
|
|
|
1833 type of window system. Can only be instanced as `pointer'.)
|
|
|
1834 'font
|
|
|
1835 (A glyph from a font; i.e. the name of a font, and glyph index into it
|
|
|
1836 of the form \"FONT fontname index [[mask-font] mask-index]\".
|
|
|
1837 Currently can only be instanced as `pointer', although this should
|
|
|
1838 probably be fixed.)
|
|
|
1839 'subwindow
|
|
|
1840 (An embedded X window; not currently implemented.)
|
|
|
1841 'autodetect
|
|
|
1842 (XEmacs tries to guess what format the data is in. If X support
|
|
|
1843 exists, the data string will be checked to see if it names a filename.
|
|
|
1844 If so, and this filename contains XBM or XPM data, the appropriate
|
|
|
1845 sort of pixmap or pointer will be created. [This includes picking up
|
|
|
1846 any specified hotspot or associated mask file.] Otherwise, if `pointer'
|
|
|
1847 is one of the allowable image-instance types and the string names a
|
|
|
1848 valid cursor-font name, the image will be created as a pointer.
|
|
|
1849 Otherwise, the image will be displayed as text. If no X support
|
|
|
1850 exists, the image will always be displayed as text.)
|
|
|
1851 'inherit
|
|
|
1852 Inherit from the background-pixmap property of a face.
|
|
|
1853
|
|
|
1854 The valid keywords are:
|
|
|
1855
|
|
|
1856 :data
|
|
|
1857 (Inline data. For most formats above, this should be a string. For
|
|
|
1858 XBM images, this should be a list of three elements: width, height, and
|
|
|
1859 a string of bit data. This keyword is not valid for instantiator
|
|
|
1860 formats `nothing' and `inherit'.)
|
|
|
1861 :file
|
|
|
1862 (Data is contained in a file. The value is the name of this file.
|
|
|
1863 If both :data and :file are specified, the image is created from
|
|
|
1864 what is specified in :data and the string in :file becomes the
|
|
|
1865 value of the `image-instance-file-name' function when applied to
|
|
|
1866 the resulting image-instance. This keyword is not valid for
|
|
|
1867 instantiator formats `nothing', `string', `formatted-string',
|
|
|
1868 `cursor-font', `font', `autodetect', and `inherit'.)
|
|
|
1869 :foreground
|
|
|
1870 :background
|
|
|
1871 (For `xbm', `xface', `cursor-font', and `font'. These keywords
|
|
|
1872 allow you to explicitly specify foreground and background colors.
|
|
|
1873 The argument should be anything acceptable to `make-color-instance'.
|
|
|
1874 This will cause what would be a `mono-pixmap' to instead be colorized
|
|
|
1875 as a two-color color-pixmap, and specifies the foreground and/or
|
|
|
1876 background colors for a pointer instead of black and white.)
|
|
|
1877 :mask-data
|
|
|
1878 (For `xbm' and `xface'. This specifies a mask to be used with the
|
|
|
1879 bitmap. The format is a list of width, height, and bits, like for
|
|
|
1880 :data.)
|
|
|
1881 :mask-file
|
|
|
1882 (For `xbm' and `xface'. This specifies a file containing the mask data.
|
|
|
1883 If neither a mask file nor inline mask data is given for an XBM image,
|
|
|
1884 and the XBM image comes from a file, XEmacs will look for a mask file
|
|
|
1885 with the same name as the image file but with \"Mask\" or \"msk\"
|
|
|
1886 appended. For example, if you specify the XBM file \"left_ptr\"
|
|
|
1887 [usually located in \"/usr/include/X11/bitmaps\"], the associated
|
|
|
1888 mask file \"left_ptrmsk\" will automatically be picked up.)
|
|
|
1889 :hotspot-x
|
|
|
1890 :hotspot-y
|
|
|
1891 (For `xbm' and `xface'. These keywords specify a hotspot if the image
|
|
|
1892 is instantiated as a `pointer'. Note that if the XBM image file
|
|
|
1893 specifies a hotspot, it will automatically be picked up if no
|
|
|
1894 explicit hotspot is given.)
|
|
|
1895 :color-symbols
|
|
|
1896 (Only for `xpm'. This specifies an alist that maps strings
|
|
|
1897 that specify symbolic color names to the actual color to be used
|
|
|
1898 for that symbolic color (in the form of a string or a color-specifier
|
|
|
1899 object). If this is not specified, the contents of `xpm-color-symbols'
|
|
|
1900 are used to generate the alist.)
|
|
|
1901 :face
|
|
|
1902 (Only for `inherit'. This specifies the face to inherit from.)
|
|
|
1903
|
|
|
1904 If instead of a vector, the instantiator is a string, it will be
|
|
|
1905 converted into a vector by looking it up according to the specs in the
|
|
|
1906 `console-type-image-conversion-list' (q.v.) for the console type of
|
|
|
1907 the domain (usually a window; sometimes a frame or device) over which
|
|
|
1908 the image is being instantiated.
|
|
|
1909
|
|
|
1910 If the instantiator specifies data from a file, the data will be read
|
|
|
1911 in at the time that the instantiator is added to the image (which may
|
|
|
1912 be well before when the image is actually displayed), and the
|
|
|
1913 instantiator will be converted into one of the inline-data forms, with
|
|
|
1914 the filename retained using a :file keyword. This implies that the
|
|
|
1915 file must exist when the instantiator is added to the image, but does
|
|
|
1916 not need to exist at any other time (e.g. it may safely be a temporary
|
|
|
1917 file).
