1130 * ERROR HANDLING:
|
|
|
1131 *
|
|
|
1132 * The JPEG library's standard error handler (jerror.c) is divided into
|
|
|
1133 * several "methods" which you can override individually. This lets you
|
|
|
1134 * adjust the behavior without duplicating a lot of code, which you might
|
|
|
1135 * have to update with each future release.
|
|
|
1136 *
|
|
|
1137 * Our example here shows how to override the "error_exit" method so that
|
|
|
1138 * control is returned to the library's caller when a fatal error occurs,
|
|
|
1139 * rather than calling exit() as the standard error_exit method does.
|
|
|
1140 *
|
|
|
1141 * We use C's setjmp/longjmp facility to return control. This means that the
|
|
|
1142 * routine which calls the JPEG library must first execute a setjmp() call to
|
|
|
1143 * establish the return point. We want the replacement error_exit to do a
|
|
|
1144 * longjmp(). But we need to make the setjmp buffer accessible to the
|
|
|
1145 * error_exit routine. To do this, we make a private extension of the
|
|
|
1146 * standard JPEG error handler object. (If we were using C++, we'd say we
|
|
|
1147 * were making a subclass of the regular error handler.)
|
|
|
1148 *
|
|
|
1149 * Here's the extended error handler struct:

2787 colors in the XPM file with whether they are the
|
|
|
2788 foreground - perhaps with logical color names somehow?
|
|
|
2789
|
|
|
2790 Once we have decided which color is the foreground, we
|
|
|
2791 need to ensure that that color corresponds to a `1' bit
|
|
|
2792 in the Pixmap. The XPM library wrote into the (1-bit)
|
|
|
2793 pixmap with XPutPixel, which will ignore all but the
|
|
|
2794 least significant bit.
|
|
|
2795
|
|
|
2796 This means that a 1 bit in the image corresponds to
|
|
|
2797 `fg' only if `fg.pixel' is odd.
|
|
|
2798
|
|
|
2799 (This also means that the image will be all the same
|
|
|
2800 color if both `fg' and `bg' are odd or even, but we can
|
|
|
2801 safely assume that that won't happen if the XPM file is
|
|
|
2802 sensible I think.)
|
|
|
2803
|
|
|
2804 The desired result is that the image use `1' to
|
|
|
2805 represent the foreground color, and `0' to represent
|
|
|
2806 the background color. So, we may need to invert the
|
|
|
2807 image to accomplish this; we invert if fg is
|
|
|
2808 odd. (Remember that WhitePixel and BlackPixel are not
|
|
|
2809 necessarily 1 and 0 respectively, though I think it
|
|
|
2810 might be safe to assume that one of them is always 1
|
|
|
2811 and the other is always 0. We also pretty much need to
|
|
|
2812 assume that one is even and the other is odd.)

3185 - When it can't convert the given string to a real cursor, it will

3186 sometimes return a "success" value, after triggering a BadPixmap
|

3187 error. It then gives you a cursor that will itself generate BadCursor
|
|
|
3188 errors. So we install this error handler to catch/notice the X error
|
|
|
3189 and take that as meaning "couldn't convert."
|
|
|
3190
|
|
|
3191 - When you tell it to find a cursor file that doesn't exist, it prints
|
|
|
3192 an error message on stderr. You can't make it not do that.
|
|
|
3193
|
|

3194 - Also, using Xmu means we can't properly hack Lisp_Image_Instance
|

3195 objects, or XPM files, or $XBMLANGPATH.
