1135 * ERROR HANDLING:
|
|
|
1136 *
|
|
|
1137 * The JPEG library's standard error handler (jerror.c) is divided into
|
|
|
1138 * several "methods" which you can override individually. This lets you
|
|
|
1139 * adjust the behavior without duplicating a lot of code, which you might
|
|
|
1140 * have to update with each future release.
|
|
|
1141 *
|
|
|
1142 * Our example here shows how to override the "error_exit" method so that
|
|
|
1143 * control is returned to the library's caller when a fatal error occurs,
|
|
|
1144 * rather than calling exit() as the standard error_exit method does.
|
|
|
1145 *
|
|
|
1146 * We use C's setjmp/longjmp facility to return control. This means that the
|
|
|
1147 * routine which calls the JPEG library must first execute a setjmp() call to
|
|
|
1148 * establish the return point. We want the replacement error_exit to do a
|
|
|
1149 * longjmp(). But we need to make the setjmp buffer accessible to the
|
|
|
1150 * error_exit routine. To do this, we make a private extension of the
|
|
|
1151 * standard JPEG error handler object. (If we were using C++, we'd say we
|
|
|
1152 * were making a subclass of the regular error handler.)
|
|
|
1153 *
|
|
|
1154 * Here's the extended error handler struct:

2784 /* With an XBM file, it's obvious which bit is foreground
|
|
|
2785 and which is background, or rather, it's implicit: in
|
|
|
2786 an XBM file, a 1 bit is foreground, and a 0 bit is
|
|
|
2787 background.
|
|
|
2788
|
|
|
2789 XCreatePixmapCursor() assumes this property of the
|
|
|
2790 pixmap it is called with as well; the `foreground'
|
|
|
2791 color argument is used for the 1 bits.
|
|
|
2792
|
|
|
2793 With an XPM file, it's tricker, since the elements of
|
|
|
2794 the pixmap don't represent FG and BG, but are actual
|
|
|
2795 pixel values. So we need to figure out which of those
|
|
|
2796 pixels is the foreground color and which is the
|
|
|
2797 background. We do it by comparing RGB and assuming
|
|
|
2798 that the darker color is the foreground. This works
|
|
|
2799 with the result of xbmtopbm|ppmtoxpm, at least.
|
|
|
2800
|
|
|
2801 It might be nice if there was some way to tag the
|
|
|
2802 colors in the XPM file with whether they are the
|
|
|
2803 foreground - perhaps with logical color names somehow?
|
|
|
2804
|
|
|
2805 Once we have decided which color is the foreground, we
|
|
|
2806 need to ensure that that color corresponds to a `1' bit
|
|
|
2807 in the Pixmap. The XPM library wrote into the (1-bit)
|
|
|
2808 pixmap with XPutPixel, which will ignore all but the
|
|
|
2809 least significant bit.
|
|
|
2810
|
|
|
2811 This means that a 1 bit in the image corresponds to
|
|
|
2812 `fg' only if `fg.pixel' is odd.
|
|
|
2813
|
|
|
2814 (This also means that the image will be all the same
|
|
|
2815 color if both `fg' and `bg' are odd or even, but we can
|
|
|
2816 safely assume that that won't happen if the XPM file is
|
|
|
2817 sensible I think.)
|
|
|
2818
|
|
|
2819 The desired result is that the image use `1' to
|
|
|
2820 represent the foreground color, and `0' to represent
|
|
|
2821 the background color. So, we may need to invert the
|
|
|
2822 image to accomplish this; we invert if fg is
|
|
|
2823 odd. (Remember that WhitePixel and BlackPixel are not
|
|
|
2824 necessarily 1 and 0 respectively, though I think it
|
|
|
2825 might be safe to assume that one of them is always 1
|
|
|
2826 and the other is always 0. We also pretty much need to
|
|
|
2827 assume that one is even and the other is odd.)

3206 sometimes return a "success" value, after triggering a BadPixmap

3207 error. It then gives you a cursor that will itself generate BadCursor

3208 errors. So we install this error handler to catch/notice the X error
|
|
|
3209 and take that as meaning "couldn't convert."
|
|
|
3210
|
|
|
3211 - When you tell it to find a cursor file that doesn't exist, it prints
|
|
|
3212 an error message on stderr. You can't make it not do that.
|
|
|
3213
|

3214 - Also, using Xmu means we can't properly hack Lisp_Image_Instance
