1557 XCreatePixmapCursor() assumes this property of the

1559 color argument is used for the 1 bits.
|
|
|
1560
|
|
|
1561 With an XPM file, it's tricker, since the elements of
|
|
|
1562 the pixmap don't represent FG and BG, but are actual
|
|
|
1563 pixel values. So we need to figure out which of those
|
|
|
1564 pixels is the foreground color and which is the
|
|
|
1565 background. We do it by comparing RGB and assuming
|
|
|
1566 that the darker color is the foreground. This works
|
|
|
1567 with the result of xbmtopbm|ppmtoxpm, at least.
|

1568

0
|
1569 It might be nice if there was some way to tag the
|
|
|
1570 colors in the XPM file with whether they are the
|
|
|
1571 foreground - perhaps with logical color names somehow?
|
|
185
|
1572
|
|
0
|
1573 Once we have decided which color is the foreground, we
|
|
|
1574 need to ensure that that color corresponds to a `1' bit
|
|
|
1575 in the Pixmap. The XPM library wrote into the (1-bit)
|
|
|
1576 pixmap with XPutPixel, which will ignore all but the
|
|
|
1577 least significant bit.
|
|
185
|
1578
|
|
0
|
1579 This means that a 1 bit in the image corresponds to
|
|
|
1580 `fg' only if `fg.pixel' is odd.
|
|
185
|
1581
|
|
0
|
1582 (This also means that the image will be all the same
|
|
|
1583 color if both `fg' and `bg' are odd or even, but we can
|
|
|
1584 safely assume that that won't happen if the XPM file is
|
|
|
1585 sensible I think.)
|
|
185
|
1586
|
|
0
|
1587 The desired result is that the image use `1' to
|
|
|
1588 represent the foreground color, and `0' to represent
|
|
|
1589 the background color. So, we may need to invert the
|
|
|
1590 image to accomplish this; we invert if fg is
|
|
|
1591 odd. (Remember that WhitePixel and BlackPixel are not
|
|
|
1592 necessarily 1 and 0 respectively, though I think it
|
|
|
1593 might be safe to assume that one of them is always 1
|
|
|
1594 and the other is always 0. We also pretty much need to
|
|
|
1595 assume that one is even and the other is odd.)

2246 an error message on stderr. You can't make it not do that.

2247
