1421 and which is background, or rather, it's implicit: in
|
|
|
1422 an XBM file, a 1 bit is foreground, and a 0 bit is
|
|
|
1423 background.
|
|
|
1424
|
|
|
1425 XCreatePixmapCursor() assumes this property of the
|
|
|
1426 pixmap it is called with as well; the `foreground'
|
|
|
1427 color argument is used for the 1 bits.
|
|
|
1428
|
|
|
1429 With an XPM file, it's tricker, since the elements of
|
|
|
1430 the pixmap don't represent FG and BG, but are actual
|
|
|
1431 pixel values. So we need to figure out which of those
|
|
|
1432 pixels is the foreground color and which is the
|
|
|
1433 background. We do it by comparing RGB and assuming
|
|
|
1434 that the darker color is the foreground. This works
|
|
|
1435 with the result of xbmtopbm|ppmtoxpm, at least.
|
|
|
1436
|
|
|
1437 It might be nice if there was some way to tag the
|
|
|
1438 colors in the XPM file with whether they are the
|
|
|
1439 foreground - perhaps with logical color names somehow?
|
|
|
1440
|
|
|
1441 Once we have decided which color is the foreground, we
|
|
|
1442 need to ensure that that color corresponds to a `1' bit
|
|
|
1443 in the Pixmap. The XPM library wrote into the (1-bit)
|
|
|
1444 pixmap with XPutPixel, which will ignore all but the
|
|
|
1445 least significant bit.
|
|
|
1446
|
|
|
1447 This means that a 1 bit in the image corresponds to
|
|
|
1448 `fg' only if `fg.pixel' is odd.
|
|
|
1449
|
|
|
1450 (This also means that the image will be all the same
|
|
|
1451 color if both `fg' and `bg' are odd or even, but we can
|
|
|
1452 safely assume that that won't happen if the XPM file is
|
|
|
1453 sensible I think.)
|
|
|
1454
|
|
|
1455 The desired result is that the image use `1' to
|
|
|
1456 represent the foreground color, and `0' to represent
|
|
|
1457 the background color. So, we may need to invert the
|
|
|
1458 image to accomplish this; we invert if fg is
|
|
|
1459 odd. (Remember that WhitePixel and BlackPixel are not
|
|
|
1460 necessarily 1 and 0 respectively, though I think it
|
|
|
1461 might be safe to assume that one of them is always 1
|
|
|
1462 and the other is always 0. We also pretty much need to
|
|
|
1463 assume that one is even and the other is odd.)

1794 an error message on stderr. You can't make it not do that.

1795

2890 domain it needs to be instantiated in until you've actually
