1773 XCreatePixmapCursor() assumes this property of the

1775 color argument is used for the 1 bits.
|
|
|
1776
|
|
|
1777 With an XPM file, it's tricker, since the elements of
|
|
|
1778 the pixmap don't represent FG and BG, but are actual
|
|
|
1779 pixel values. So we need to figure out which of those
|
|
|
1780 pixels is the foreground color and which is the
|
|
|
1781 background. We do it by comparing RGB and assuming
|
|
|
1782 that the darker color is the foreground. This works
|
|
|
1783 with the result of xbmtopbm|ppmtoxpm, at least.

0
|
1785 It might be nice if there was some way to tag the
|
|
|
1786 colors in the XPM file with whether they are the
|
|
|
1787 foreground - perhaps with logical color names somehow?
|
|
185
|
1788
|
|
0
|
1789 Once we have decided which color is the foreground, we
|
|
|
1790 need to ensure that that color corresponds to a `1' bit
|
|
|
1791 in the Pixmap. The XPM library wrote into the (1-bit)
|
|
|
1792 pixmap with XPutPixel, which will ignore all but the
|
|
|
1793 least significant bit.
|
|
185
|
1794
|
|
0
|
1795 This means that a 1 bit in the image corresponds to
|
|
|
1796 `fg' only if `fg.pixel' is odd.
|
|
185
|
1797
|
|
0
|
1798 (This also means that the image will be all the same
|
|
|
1799 color if both `fg' and `bg' are odd or even, but we can
|
|
|
1800 safely assume that that won't happen if the XPM file is
|
|
|
1801 sensible I think.)
|
|
185
|
1802
|
|
0
|
1803 The desired result is that the image use `1' to
|
|
|
1804 represent the foreground color, and `0' to represent
|
|
|
1805 the background color. So, we may need to invert the
|
|
|
1806 image to accomplish this; we invert if fg is
|
|
|
1807 odd. (Remember that WhitePixel and BlackPixel are not
|
|
|
1808 necessarily 1 and 0 respectively, though I think it
|
|
|
1809 might be safe to assume that one of them is always 1
|
|
|
1810 and the other is always 0. We also pretty much need to
|
|
|
1811 assume that one is even and the other is odd.)

|
|
|
1989 * several "methods" which you can override individually. This lets you
|
|
|
1990 * adjust the behavior without duplicating a lot of code, which you might

1991 * have to update with each future release.
|

|
1992 *
|
|
|
1993 * Our example here shows how to override the "error_exit" method so that
|
|
|
1994 * control is returned to the library's caller when a fatal error occurs,
|
|
|
1995 * rather than calling exit() as the standard error_exit method does.
|
|
|
1996 *
|
|
|
1997 * We use C's setjmp/longjmp facility to return control. This means that the
|
|
|
1998 * routine which calls the JPEG library must first execute a setjmp() call to
|
|
|
1999 * establish the return point. We want the replacement error_exit to do a
|

2000 * longjmp(). But we need to make the setjmp buffer accessible to the
|
|

2001 * error_exit routine. To do this, we make a private extension of the

2002 * standard JPEG error handler object. (If we were using C++, we'd say we

3985 - When it can't convert the given string to a real cursor, it will
|
|
|
3986 sometimes return a "success" value, after triggering a BadPixmap
|
|
|
3987 error. It then gives you a cursor that will itself generate BadCursor
|
|
|
3988 errors. So we install this error handler to catch/notice the X error
|
|
|
3989 and take that as meaning "couldn't convert."

3991 - When you tell it to find a cursor file that doesn't exist, it prints
|
|
|
3992 an error message on stderr. You can't make it not do that.

3994 - Also, using Xmu means we can't properly hack Lisp_Image_Instance
