1144 * ERROR HANDLING:
|
|
|
1145 *
|
|
|
1146 * The JPEG library's standard error handler (jerror.c) is divided into
|
|
|
1147 * several "methods" which you can override individually. This lets you
|
|
|
1148 * adjust the behavior without duplicating a lot of code, which you might
|
|
|
1149 * have to update with each future release.
|
|
|
1150 *
|
|
|
1151 * Our example here shows how to override the "error_exit" method so that
|
|
|
1152 * control is returned to the library's caller when a fatal error occurs,
|
|
|
1153 * rather than calling exit() as the standard error_exit method does.
|
|
|
1154 *
|
|
|
1155 * We use C's setjmp/longjmp facility to return control. This means that the
|
|
|
1156 * routine which calls the JPEG library must first execute a setjmp() call to
|
|
|
1157 * establish the return point. We want the replacement error_exit to do a
|
|
|
1158 * longjmp(). But we need to make the setjmp buffer accessible to the
|
|
|
1159 * error_exit routine. To do this, we make a private extension of the
|
|
|
1160 * standard JPEG error handler object. (If we were using C++, we'd say we
|
|
|
1161 * were making a subclass of the regular error handler.)
|
|
|
1162 *
|

2824 and which is background, or rather, it's implicit: in
|
|
|
2825 an XBM file, a 1 bit is foreground, and a 0 bit is
|
|
|
2826 background.
|
|
|
2827
|
|
|
2828 XCreatePixmapCursor() assumes this property of the
|
|
|
2829 pixmap it is called with as well; the `foreground'
|
|
|
2830 color argument is used for the 1 bits.
|
|
|
2831
|
|
|
2832 With an XPM file, it's tricker, since the elements of
|
|
|
2833 the pixmap don't represent FG and BG, but are actual
|
|
|
2834 pixel values. So we need to figure out which of those
|
|
|
2835 pixels is the foreground color and which is the
|
|
|
2836 background. We do it by comparing RGB and assuming
|
|
|
2837 that the darker color is the foreground. This works
|
|
|
2838 with the result of xbmtopbm|ppmtoxpm, at least.
|
|
|
2839
|
|
|
2840 It might be nice if there was some way to tag the
|
|
|
2841 colors in the XPM file with whether they are the
|
|
|
2842 foreground - perhaps with logical color names somehow?
|
|
|
2843
|
|
|
2844 Once we have decided which color is the foreground, we
|
|
|
2845 need to ensure that that color corresponds to a `1' bit
|
|
|
2846 in the Pixmap. The XPM library wrote into the (1-bit)
|
|
|
2847 pixmap with XPutPixel, which will ignore all but the
|
|
|
2848 least significant bit.
|
|
|
2849
|
|
|
2850 This means that a 1 bit in the image corresponds to
|
|
|
2851 `fg' only if `fg.pixel' is odd.
|
|
|
2852
|
|
|
2853 (This also means that the image will be all the same
|
|
|
2854 color if both `fg' and `bg' are odd or even, but we can
|
|
|
2855 safely assume that that won't happen if the XPM file is
|
|
|
2856 sensible I think.)
|
|
|
2857
|
|
|
2858 The desired result is that the image use `1' to
|
|
|
2859 represent the foreground color, and `0' to represent
|
|
|
2860 the background color. So, we may need to invert the
|
|
|
2861 image to accomplish this; we invert if fg is
|
|
|
2862 odd. (Remember that WhitePixel and BlackPixel are not
|
|
|
2863 necessarily 1 and 0 respectively, though I think it
|
|
|
2864 might be safe to assume that one of them is always 1
|
|
|
2865 and the other is always 0. We also pretty much need to
|
|
|
2866 assume that one is even and the other is odd.)

3251 an error message on stderr. You can't make it not do that.

3252
