1387 XCreatePixmapCursor() assumes this property of the

1388 pixmap it is called with as well; the `foreground'

|
1389 color argument is used for the 1 bits.
|
|
|
1390
|
|
|
1391 With an XPM file, it's tricker, since the elements of
|
|
|
1392 the pixmap don't represent FG and BG, but are actual
|
|
|
1393 pixel values. So we need to figure out which of those
|
|
|
1394 pixels is the foreground color and which is the
|
|
|
1395 background. We do it by comparing RGB and assuming
|
|
|
1396 that the darker color is the foreground. This works
|
|
|
1397 with the result of xbmtopbm|ppmtoxpm, at least.
|

1398

0
|
1399 It might be nice if there was some way to tag the
|
|
|
1400 colors in the XPM file with whether they are the
|
|
|
1401 foreground - perhaps with logical color names somehow?
|
|
185
|
1402
|
|
0
|
1403 Once we have decided which color is the foreground, we
|
|
|
1404 need to ensure that that color corresponds to a `1' bit
|
|
|
1405 in the Pixmap. The XPM library wrote into the (1-bit)
|
|
|
1406 pixmap with XPutPixel, which will ignore all but the
|
|
|
1407 least significant bit.
|
|
185
|
1408
|
|
0
|
1409 This means that a 1 bit in the image corresponds to
|
|
|
1410 `fg' only if `fg.pixel' is odd.
|
|
185
|
1411
|
|
0
|
1412 (This also means that the image will be all the same
|
|
|
1413 color if both `fg' and `bg' are odd or even, but we can
|
|
|
1414 safely assume that that won't happen if the XPM file is
|
|
|
1415 sensible I think.)
|
|
185
|
1416
|
|
0
|
1417 The desired result is that the image use `1' to
|
|
|
1418 represent the foreground color, and `0' to represent
|
|
|
1419 the background color. So, we may need to invert the
|
|
|
1420 image to accomplish this; we invert if fg is
|
|
|
1421 odd. (Remember that WhitePixel and BlackPixel are not
|
|
|
1422 necessarily 1 and 0 respectively, though I think it
|
|
|
1423 might be safe to assume that one of them is always 1
|
|
|
1424 and the other is always 0. We also pretty much need to
|
|
|
1425 assume that one is even and the other is odd.)

1602 * The JPEG library's standard error handler (jerror.c) is divided into
|
|
|
1603 * several "methods" which you can override individually. This lets you
|
|
|
1604 * adjust the behavior without duplicating a lot of code, which you might
|

|
1605 * have to update with each future release.
|
|
|
1606 *
|
|
|
1607 * Our example here shows how to override the "error_exit" method so that
|
|
|
1608 * control is returned to the library's caller when a fatal error occurs,
|
|
|
1609 * rather than calling exit() as the standard error_exit method does.
|
|
|
1610 *
|
|
|
1611 * We use C's setjmp/longjmp facility to return control. This means that the
|
|
|
1612 * routine which calls the JPEG library must first execute a setjmp() call to
|
|
|
1613 * establish the return point. We want the replacement error_exit to do a
|
|
|
1614 * longjmp(). But we need to make the setjmp buffer accessible to the
|
|
|
1615 * error_exit routine. To do this, we make a private extension of the
|
|
|
1616 * standard JPEG error handler object. (If we were using C++, we'd say we

1617 * were making a subclass of the regular error handler.)

3607 an error message on stderr. You can't make it not do that.
