1564 XCreatePixmapCursor() assumes this property of the

1566 color argument is used for the 1 bits.
|
|
|
1567
|
|
|
1568 With an XPM file, it's tricker, since the elements of
|
|
|
1569 the pixmap don't represent FG and BG, but are actual
|
|
|
1570 pixel values. So we need to figure out which of those
|
|
|
1571 pixels is the foreground color and which is the
|
|
|
1572 background. We do it by comparing RGB and assuming
|
|
|
1573 that the darker color is the foreground. This works
|
|
|
1574 with the result of xbmtopbm|ppmtoxpm, at least.

1575

0
|
1576 It might be nice if there was some way to tag the

1577 colors in the XPM file with whether they are the

|
|
1578 foreground - perhaps with logical color names somehow?
|
|
185
|
1579
|
|
0
|
1580 Once we have decided which color is the foreground, we
|
|
|
1581 need to ensure that that color corresponds to a `1' bit
|
|
|
1582 in the Pixmap. The XPM library wrote into the (1-bit)
|
|
|
1583 pixmap with XPutPixel, which will ignore all but the
|
|
|
1584 least significant bit.
|
|
185
|
1585
|
|
0
|
1586 This means that a 1 bit in the image corresponds to
|
|
|
1587 `fg' only if `fg.pixel' is odd.
|
|
185
|
1588
|
|
0
|
1589 (This also means that the image will be all the same
|
|
|
1590 color if both `fg' and `bg' are odd or even, but we can
|
|
|
1591 safely assume that that won't happen if the XPM file is
|
|
|
1592 sensible I think.)
|
|
185
|
1593
|
|
0
|
1594 The desired result is that the image use `1' to
|
|
|
1595 represent the foreground color, and `0' to represent
|
|
|
1596 the background color. So, we may need to invert the
|
|
|
1597 image to accomplish this; we invert if fg is
|
|
|
1598 odd. (Remember that WhitePixel and BlackPixel are not
|
|
|
1599 necessarily 1 and 0 respectively, though I think it
|
|
|
1600 might be safe to assume that one of them is always 1
|
|
|
1601 and the other is always 0. We also pretty much need to
|
|
|
1602 assume that one is even and the other is odd.)

2253 an error message on stderr. You can't make it not do that.
