1520 an XBM file, a 1 bit is foreground, and a 0 bit is
|
|
|
1521 background.
|
|
|
1522
|
|
|
1523 XCreatePixmapCursor() assumes this property of the
|
|
|
1524 pixmap it is called with as well; the `foreground'
|
|
|
1525 color argument is used for the 1 bits.
|
|
|
1526
|
|
|
1527 With an XPM file, it's tricker, since the elements of
|
|
|
1528 the pixmap don't represent FG and BG, but are actual
|
|
|
1529 pixel values. So we need to figure out which of those
|
|
|
1530 pixels is the foreground color and which is the
|
|
|
1531 background. We do it by comparing RGB and assuming
|
|
|
1532 that the darker color is the foreground. This works
|
|
|
1533 with the result of xbmtopbm|ppmtoxpm, at least.
|
|
|
1534
|
|
|
1535 It might be nice if there was some way to tag the
|
|
|
1536 colors in the XPM file with whether they are the
|
|
|
1537 foreground - perhaps with logical color names somehow?
|
|
|
1538
|
|
|
1539 Once we have decided which color is the foreground, we
|
|
|
1540 need to ensure that that color corresponds to a `1' bit
|
|
|
1541 in the Pixmap. The XPM library wrote into the (1-bit)
|
|
|
1542 pixmap with XPutPixel, which will ignore all but the
|
|
|
1543 least significant bit.
|
|
|
1544
|
|
|
1545 This means that a 1 bit in the image corresponds to
|
|
|
1546 `fg' only if `fg.pixel' is odd.
|
|
|
1547
|
|
|
1548 (This also means that the image will be all the same
|
|
|
1549 color if both `fg' and `bg' are odd or even, but we can
|
|
|
1550 safely assume that that won't happen if the XPM file is
|
|
|
1551 sensible I think.)
|
|
|
1552
|
|
|
1553 The desired result is that the image use `1' to
|
|
|
1554 represent the foreground color, and `0' to represent
|
|
|
1555 the background color. So, we may need to invert the
|
|
|
1556 image to accomplish this; we invert if fg is
|
|
|
1557 odd. (Remember that WhitePixel and BlackPixel are not
|
|
|
1558 necessarily 1 and 0 respectively, though I think it
|
|
|
1559 might be safe to assume that one of them is always 1
|
|
|
1560 and the other is always 0. We also pretty much need to
|
|
|
1561 assume that one is even and the other is odd.)
