1416 and which is background, or rather, it's implicit: in
|
|
|
1417 an XBM file, a 1 bit is foreground, and a 0 bit is
|
|
|
1418 background.
|
|
|
1419
|
|
|
1420 XCreatePixmapCursor() assumes this property of the
|
|
|
1421 pixmap it is called with as well; the `foreground'
|
|
|
1422 color argument is used for the 1 bits.
|
|
|
1423
|
|
|
1424 With an XPM file, it's tricker, since the elements of
|
|
|
1425 the pixmap don't represent FG and BG, but are actual
|
|
|
1426 pixel values. So we need to figure out which of those
|
|
|
1427 pixels is the foreground color and which is the
|
|
|
1428 background. We do it by comparing RGB and assuming
|
|
|
1429 that the darker color is the foreground. This works
|
|
|
1430 with the result of xbmtopbm|ppmtoxpm, at least.
|
|
|
1431
|
|
|
1432 It might be nice if there was some way to tag the
|
|
|
1433 colors in the XPM file with whether they are the
|
|
|
1434 foreground - perhaps with logical color names somehow?
|
|
|
1435
|
|
|
1436 Once we have decided which color is the foreground, we
|
|
|
1437 need to ensure that that color corresponds to a `1' bit
|
|
|
1438 in the Pixmap. The XPM library wrote into the (1-bit)
|
|
|
1439 pixmap with XPutPixel, which will ignore all but the
|
|
|
1440 least significant bit.
|
|
|
1441
|
|
|
1442 This means that a 1 bit in the image corresponds to
|
|
|
1443 `fg' only if `fg.pixel' is odd.
|
|
|
1444
|
|
|
1445 (This also means that the image will be all the same
|
|
|
1446 color if both `fg' and `bg' are odd or even, but we can
|
|
|
1447 safely assume that that won't happen if the XPM file is
|
|
|
1448 sensible I think.)
|
|
|
1449
|
|
|
1450 The desired result is that the image use `1' to
|
|
|
1451 represent the foreground color, and `0' to represent
|
|
|
1452 the background color. So, we may need to invert the
|
|
|
1453 image to accomplish this; we invert if fg is
|
|
|
1454 odd. (Remember that WhitePixel and BlackPixel are not
|
|
|
1455 necessarily 1 and 0 respectively, though I think it
|
|
|
1456 might be safe to assume that one of them is always 1
|
|
|
1457 and the other is always 0. We also pretty much need to
|
|
|
1458 assume that one is even and the other is odd.)

1790 an error message on stderr. You can't make it not do that.

2917 string you have to prioritise cursors. Instead we will force users

2921 domain it needs to be instantiated in until you've actually

2922 instantiated it, which mucks up caching.
