1423 and which is background, or rather, it's implicit: in
|
|
|
1424 an XBM file, a 1 bit is foreground, and a 0 bit is
|
|
|
1425 background.
|
|
|
1426
|
|
|
1427 XCreatePixmapCursor() assumes this property of the
|
|
|
1428 pixmap it is called with as well; the `foreground'
|
|
|
1429 color argument is used for the 1 bits.
|
|
|
1430
|
|
|
1431 With an XPM file, it's tricker, since the elements of
|
|
|
1432 the pixmap don't represent FG and BG, but are actual
|
|
|
1433 pixel values. So we need to figure out which of those
|
|
|
1434 pixels is the foreground color and which is the
|
|
|
1435 background. We do it by comparing RGB and assuming
|
|
|
1436 that the darker color is the foreground. This works
|
|
|
1437 with the result of xbmtopbm|ppmtoxpm, at least.
|
|
|
1438
|
|
|
1439 It might be nice if there was some way to tag the
|
|
|
1440 colors in the XPM file with whether they are the
|
|
|
1441 foreground - perhaps with logical color names somehow?
|
|
|
1442
|
|
|
1443 Once we have decided which color is the foreground, we
|
|
|
1444 need to ensure that that color corresponds to a `1' bit
|
|
|
1445 in the Pixmap. The XPM library wrote into the (1-bit)
|
|
|
1446 pixmap with XPutPixel, which will ignore all but the
|
|
|
1447 least significant bit.
|
|
|
1448
|
|
|
1449 This means that a 1 bit in the image corresponds to
|
|
|
1450 `fg' only if `fg.pixel' is odd.
|
|
|
1451
|
|
|
1452 (This also means that the image will be all the same
|
|
|
1453 color if both `fg' and `bg' are odd or even, but we can
|
|
|
1454 safely assume that that won't happen if the XPM file is
|
|
|
1455 sensible I think.)
|
|
|
1456
|
|
|
1457 The desired result is that the image use `1' to
|
|
|
1458 represent the foreground color, and `0' to represent
|
|
|
1459 the background color. So, we may need to invert the
|
|
|
1460 image to accomplish this; we invert if fg is
|
|
|
1461 odd. (Remember that WhitePixel and BlackPixel are not
|
|
|
1462 necessarily 1 and 0 respectively, though I think it
|
|
|
1463 might be safe to assume that one of them is always 1
|
|
|
1464 and the other is always 0. We also pretty much need to
|
|
|
1465 assume that one is even and the other is odd.)

1796 an error message on stderr. You can't make it not do that.
