1602 XCreatePixmapCursor() assumes this property of the

1604 color argument is used for the 1 bits.
|
|
|
1605
|
|
|
1606 With an XPM file, it's tricker, since the elements of
|
|
|
1607 the pixmap don't represent FG and BG, but are actual
|
|
|
1608 pixel values. So we need to figure out which of those
|
|
|
1609 pixels is the foreground color and which is the
|
|
|
1610 background. We do it by comparing RGB and assuming
|
|
|
1611 that the darker color is the foreground. This works
|

1612 with the result of xbmtopbm|ppmtoxpm, at least.

1614 It might be nice if there was some way to tag the

1615 colors in the XPM file with whether they are the

1616 foreground - perhaps with logical color names somehow?
|
|
185
|
1617
|
|
0
|
1618 Once we have decided which color is the foreground, we
|
|
|
1619 need to ensure that that color corresponds to a `1' bit
|
|
|
1620 in the Pixmap. The XPM library wrote into the (1-bit)
|
|
|
1621 pixmap with XPutPixel, which will ignore all but the
|
|
|
1622 least significant bit.
|
|
185
|
1623
|
|
0
|
1624 This means that a 1 bit in the image corresponds to
|
|
|
1625 `fg' only if `fg.pixel' is odd.
|
|
185
|
1626
|
|
0
|
1627 (This also means that the image will be all the same
|
|
|
1628 color if both `fg' and `bg' are odd or even, but we can
|
|
|
1629 safely assume that that won't happen if the XPM file is
|
|
|
1630 sensible I think.)
|
|
185
|
1631
|
|
0
|
1632 The desired result is that the image use `1' to
|
|
|
1633 represent the foreground color, and `0' to represent
|
|
|
1634 the background color. So, we may need to invert the
|
|
|
1635 image to accomplish this; we invert if fg is
|
|
|
1636 odd. (Remember that WhitePixel and BlackPixel are not
|
|
|
1637 necessarily 1 and 0 respectively, though I think it
|
|
|
1638 might be safe to assume that one of them is always 1
|
|
|
1639 and the other is always 0. We also pretty much need to
|
|
|
1640 assume that one is even and the other is odd.)

1815 * ERROR HANDLING:
|
|
|
1816 *
|
|
|
1817 * The JPEG library's standard error handler (jerror.c) is divided into
|
|
|
1818 * several "methods" which you can override individually. This lets you
|
|
|
1819 * adjust the behavior without duplicating a lot of code, which you might
|
|
|
1820 * have to update with each future release.
|
|
|
1821 *
|
|
|
1822 * Our example here shows how to override the "error_exit" method so that
|
|
|
1823 * control is returned to the library's caller when a fatal error occurs,
|
|
|
1824 * rather than calling exit() as the standard error_exit method does.
|
|
|
1825 *
|
|
|
1826 * We use C's setjmp/longjmp facility to return control. This means that the
|
|
|
1827 * routine which calls the JPEG library must first execute a setjmp() call to
|
|
|
1828 * establish the return point. We want the replacement error_exit to do a
|
|
|
1829 * longjmp(). But we need to make the setjmp buffer accessible to the
|
|
|
1830 * error_exit routine. To do this, we make a private extension of the
|
|
|
1831 * standard JPEG error handler object. (If we were using C++, we'd say we
|
|
|
1832 * were making a subclass of the regular error handler.)
|
|
|
1833 *
|
|
|
1834 * Here's the extended error handler struct:

3822 an error message on stderr. You can't make it not do that.
