1821 XCreatePixmapCursor() assumes this property of the

1823 color argument is used for the 1 bits.
|
|
|
1824
|
|
|
1825 With an XPM file, it's tricker, since the elements of
|
|
|
1826 the pixmap don't represent FG and BG, but are actual
|
|
|
1827 pixel values. So we need to figure out which of those
|
|
|
1828 pixels is the foreground color and which is the
|
|
|
1829 background. We do it by comparing RGB and assuming
|
|
|
1830 that the darker color is the foreground. This works
|
|

1831 with the result of xbmtopbm|ppmtoxpm, at least.

1833 It might be nice if there was some way to tag the

1834 colors in the XPM file with whether they are the

|
|
1835 foreground - perhaps with logical color names somehow?
|
|
185
|
1836
|
|
0
|
1837 Once we have decided which color is the foreground, we
|
|
|
1838 need to ensure that that color corresponds to a `1' bit
|
|
|
1839 in the Pixmap. The XPM library wrote into the (1-bit)
|
|
|
1840 pixmap with XPutPixel, which will ignore all but the
|
|
|
1841 least significant bit.
|
|
185
|
1842
|
|
0
|
1843 This means that a 1 bit in the image corresponds to
|
|
|
1844 `fg' only if `fg.pixel' is odd.
|
|
185
|
1845
|
|
0
|
1846 (This also means that the image will be all the same
|
|
|
1847 color if both `fg' and `bg' are odd or even, but we can
|
|
|
1848 safely assume that that won't happen if the XPM file is
|
|
|
1849 sensible I think.)
|
|
185
|
1850
|
|
0
|
1851 The desired result is that the image use `1' to
|
|
|
1852 represent the foreground color, and `0' to represent
|
|
|
1853 the background color. So, we may need to invert the
|
|
|
1854 image to accomplish this; we invert if fg is
|
|
|
1855 odd. (Remember that WhitePixel and BlackPixel are not
|
|
|
1856 necessarily 1 and 0 respectively, though I think it
|
|
|
1857 might be safe to assume that one of them is always 1
|
|
|
1858 and the other is always 0. We also pretty much need to
|
|
|
1859 assume that one is even and the other is odd.)

|
|
|
2037 * several "methods" which you can override individually. This lets you
|
|
|
2038 * adjust the behavior without duplicating a lot of code, which you might

|

2041 * Our example here shows how to override the "error_exit" method so that

|
2042 * control is returned to the library's caller when a fatal error occurs,
|
|
|
2043 * rather than calling exit() as the standard error_exit method does.
|
|
|
2044 *
|
|
|
2045 * We use C's setjmp/longjmp facility to return control. This means that the
|
|

|
|
|
2047 * establish the return point. We want the replacement error_exit to do a
|
|
|
2048 * longjmp(). But we need to make the setjmp buffer accessible to the
|
|
|
2049 * error_exit routine. To do this, we make a private extension of the
|
|
|
2050 * standard JPEG error handler object. (If we were using C++, we'd say we

2051 * were making a subclass of the regular error handler.)

4034 - When it can't convert the given string to a real cursor, it will
|

4035 sometimes return a "success" value, after triggering a BadPixmap
|
|
|
4036 error. It then gives you a cursor that will itself generate BadCursor
|
|
|
4037 errors. So we install this error handler to catch/notice the X error
|
|
|
4038 and take that as meaning "couldn't convert."
|
|
|
4039
|
|
|
4040 - When you tell it to find a cursor file that doesn't exist, it prints
|
|
|
4041 an error message on stderr. You can't make it not do that.
|
|
|
4042
|
|
|
4043 - Also, using Xmu means we can't properly hack Lisp_Image_Instance
|
|

4044 objects, or XPM files, or $XBMLANGPATH.
