1419 and which is background, or rather, it's implicit: in
|
|
|
1420 an XBM file, a 1 bit is foreground, and a 0 bit is
|
|
|
1421 background.
|
|
|
1422
|
|
|
1423 XCreatePixmapCursor() assumes this property of the
|
|
|
1424 pixmap it is called with as well; the `foreground'
|
|
|
1425 color argument is used for the 1 bits.
|
|
|
1426
|
|
|
1427 With an XPM file, it's tricker, since the elements of
|
|
|
1428 the pixmap don't represent FG and BG, but are actual
|
|
|
1429 pixel values. So we need to figure out which of those
|
|
|
1430 pixels is the foreground color and which is the
|
|
|
1431 background. We do it by comparing RGB and assuming
|
|
|
1432 that the darker color is the foreground. This works
|
|
|
1433 with the result of xbmtopbm|ppmtoxpm, at least.
|
|
|
1434
|
|
|
1435 It might be nice if there was some way to tag the
|
|
|
1436 colors in the XPM file with whether they are the
|
|
|
1437 foreground - perhaps with logical color names somehow?
|
|
|
1438
|
|
|
1439 Once we have decided which color is the foreground, we
|
|
|
1440 need to ensure that that color corresponds to a `1' bit
|
|
|
1441 in the Pixmap. The XPM library wrote into the (1-bit)
|
|
|
1442 pixmap with XPutPixel, which will ignore all but the
|
|
|
1443 least significant bit.
|
|
|
1444
|
|
|
1445 This means that a 1 bit in the image corresponds to
|
|
|
1446 `fg' only if `fg.pixel' is odd.
|
|
|
1447
|
|
|
1448 (This also means that the image will be all the same
|
|
|
1449 color if both `fg' and `bg' are odd or even, but we can
|
|
|
1450 safely assume that that won't happen if the XPM file is
|
|
|
1451 sensible I think.)
|
|
|
1452
|
|
|
1453 The desired result is that the image use `1' to
|
|
|
1454 represent the foreground color, and `0' to represent
|
|
|
1455 the background color. So, we may need to invert the
|
|
|
1456 image to accomplish this; we invert if fg is
|
|
|
1457 odd. (Remember that WhitePixel and BlackPixel are not
|
|
|
1458 necessarily 1 and 0 respectively, though I think it
|
|
|
1459 might be safe to assume that one of them is always 1
|
|
|
1460 and the other is always 0. We also pretty much need to
|
|
|
1461 assume that one is even and the other is odd.)

1793 an error message on stderr. You can't make it not do that.

1794

2918 domain it needs to be instantiated in until you've actually
