1864 XCreatePixmapCursor() assumes this property of the

1866 color argument is used for the 1 bits.
|
|
|
1867
|
|
|
1868 With an XPM file, it's tricker, since the elements of
|
|
|
1869 the pixmap don't represent FG and BG, but are actual
|
|
|
1870 pixel values. So we need to figure out which of those
|
|
|
1871 pixels is the foreground color and which is the
|
|
|
1872 background. We do it by comparing RGB and assuming
|
|
|
1873 that the darker color is the foreground. This works
|

1874 with the result of xbmtopbm|ppmtoxpm, at least.

0

1876 It might be nice if there was some way to tag the

1877 colors in the XPM file with whether they are the

1878 foreground - perhaps with logical color names somehow?
|
|
185
|
1879
|
|
0
|
1880 Once we have decided which color is the foreground, we
|
|
|
1881 need to ensure that that color corresponds to a `1' bit
|
|
|
1882 in the Pixmap. The XPM library wrote into the (1-bit)
|
|
|
1883 pixmap with XPutPixel, which will ignore all but the
|
|
|
1884 least significant bit.
|
|
185
|
1885
|
|
0
|
1886 This means that a 1 bit in the image corresponds to
|
|
|
1887 `fg' only if `fg.pixel' is odd.
|
|
185
|
1888
|
|
0
|
1889 (This also means that the image will be all the same
|
|
|
1890 color if both `fg' and `bg' are odd or even, but we can
|
|
|
1891 safely assume that that won't happen if the XPM file is
|
|
|
1892 sensible I think.)
|
|
185
|
1893
|
|
0
|
1894 The desired result is that the image use `1' to
|
|
|
1895 represent the foreground color, and `0' to represent
|
|
|
1896 the background color. So, we may need to invert the
|
|
|
1897 image to accomplish this; we invert if fg is
|
|
|
1898 odd. (Remember that WhitePixel and BlackPixel are not
|
|
|
1899 necessarily 1 and 0 respectively, though I think it
|
|
|
1900 might be safe to assume that one of them is always 1
|
|
|
1901 and the other is always 0. We also pretty much need to
|
|
|
1902 assume that one is even and the other is odd.)

2077 * ERROR HANDLING:
|
|
|
2078 *
|
|
|
2079 * The JPEG library's standard error handler (jerror.c) is divided into
|
|
|
2080 * several "methods" which you can override individually. This lets you
|
|
|
2081 * adjust the behavior without duplicating a lot of code, which you might
|
|
|
2082 * have to update with each future release.
|
|
|
2083 *
|
|
|
2084 * Our example here shows how to override the "error_exit" method so that
|
|
|
2085 * control is returned to the library's caller when a fatal error occurs,
|
|
|
2086 * rather than calling exit() as the standard error_exit method does.
|
|
|
2087 *
|
|
|
2088 * We use C's setjmp/longjmp facility to return control. This means that the
|
|
|
2089 * routine which calls the JPEG library must first execute a setjmp() call to
|
|
|
2090 * establish the return point. We want the replacement error_exit to do a
|
|
|
2091 * longjmp(). But we need to make the setjmp buffer accessible to the
|
|
|
2092 * error_exit routine. To do this, we make a private extension of the
|
|
|
2093 * standard JPEG error handler object. (If we were using C++, we'd say we
|
|
|
2094 * were making a subclass of the regular error handler.)
|
|
|
2095 *
|
|
|
2096 * Here's the extended error handler struct:

4076 error. It then gives you a cursor that will itself generate BadCursor

4077 errors. So we install this error handler to catch/notice the X error

4078 and take that as meaning "couldn't convert."
|
|

4079
|
|
|
4080 - When you tell it to find a cursor file that doesn't exist, it prints
|
|
|
4081 an error message on stderr. You can't make it not do that.
|
|
|
4082
|
