1161 * ERROR HANDLING:
|
|
|
1162 *
|
|
|
1163 * The JPEG library's standard error handler (jerror.c) is divided into
|
|
|
1164 * several "methods" which you can override individually. This lets you
|
|
|
1165 * adjust the behavior without duplicating a lot of code, which you might
|
|
|
1166 * have to update with each future release.
|
|
|
1167 *
|
|
|
1168 * Our example here shows how to override the "error_exit" method so that
|
|
|
1169 * control is returned to the library's caller when a fatal error occurs,
|
|
|
1170 * rather than calling exit() as the standard error_exit method does.
|
|
|
1171 *
|
|
|
1172 * We use C's setjmp/longjmp facility to return control. This means that the
|
|
|
1173 * routine which calls the JPEG library must first execute a setjmp() call to
|
|
|
1174 * establish the return point. We want the replacement error_exit to do a
|
|
|
1175 * longjmp(). But we need to make the setjmp buffer accessible to the
|
|
|
1176 * error_exit routine. To do this, we make a private extension of the
|
|
|
1177 * standard JPEG error handler object. (If we were using C++, we'd say we
|
|
|
1178 * were making a subclass of the regular error handler.)
|
|
|
1179 *
|
|
|
1180 * Here's the extended error handler struct:

1408 8-bit color in case it's not already (many JPEGs are stored in

1409 24-bit color). "Two-pass quantize" means that the colormap

1410 is determined on-the-fly for this particular image rather than

1411 quantizing to a supplied colormap. We can get away with this

1415 way of doing things -- we could quantize an image that has

1416 lots of very similar colors, and eat up the colormap with these

1417 (useless to other images) colors. Unfortunately I don't think

1418 there's any "general" way of maximizing the overall image

1419 quality of lots of images, given that we don't know the

1421 could do would be various sorts of heuristics, which I don't

1422 feel like dealing with now. A better scheme would be the

1423 way things are done under MS Windows, where the colormap is
|
|

1424 dynamically adjusted for various applications; but that kind

2856 XCreatePixmapCursor() assumes this property of the

2858 color argument is used for the 1 bits.
|
|
|
2859
|
|
|
2860 With an XPM file, it's tricker, since the elements of
|
|
|
2861 the pixmap don't represent FG and BG, but are actual
|
|
|
2862 pixel values. So we need to figure out which of those
|
|
|
2863 pixels is the foreground color and which is the
|
|
|
2864 background. We do it by comparing RGB and assuming
|
|
|
2865 that the darker color is the foreground. This works
|
|
|
2866 with the result of xbmtopbm|ppmtoxpm, at least.
|
|
185
|
2867
|
|
0
|
2868 It might be nice if there was some way to tag the
|
|
|
2869 colors in the XPM file with whether they are the
|
|
|
2870 foreground - perhaps with logical color names somehow?
|
|
185
|
2871
|
|
0
|
2872 Once we have decided which color is the foreground, we
|
|
|
2873 need to ensure that that color corresponds to a `1' bit
|
|
|
2874 in the Pixmap. The XPM library wrote into the (1-bit)
|
|
|
2875 pixmap with XPutPixel, which will ignore all but the
|
|
|
2876 least significant bit.
|
|
185
|
2877
|
|
0
|
2878 This means that a 1 bit in the image corresponds to
|
|
|
2879 `fg' only if `fg.pixel' is odd.
|
|
185
|
2880
|
|
0
|
2881 (This also means that the image will be all the same
|
|
|
2882 color if both `fg' and `bg' are odd or even, but we can
|
|
|
2883 safely assume that that won't happen if the XPM file is
|
|
|
2884 sensible I think.)
|
|
185
|
2885
|
|
0
|
2886 The desired result is that the image use `1' to
|
|
|
2887 represent the foreground color, and `0' to represent
|
|
|
2888 the background color. So, we may need to invert the
|
|
|
2889 image to accomplish this; we invert if fg is
|
|
|
2890 odd. (Remember that WhitePixel and BlackPixel are not
|
|
|
2891 necessarily 1 and 0 respectively, though I think it
|
|
|
2892 might be safe to assume that one of them is always 1
|
|
|
2893 and the other is always 0. We also pretty much need to
|
|
|
2894 assume that one is even and the other is odd.)

3289 an error message on stderr. You can't make it not do that.
