|
|
|
1366 and which is background, or rather, it's implicit: in

1370 XCreatePixmapCursor() assumes this property of the
|
|
|
1371 pixmap it is called with as well; the `foreground'
|
|
|
1372 color argument is used for the 1 bits.
|
|
|
1373
|
|
|
1374 With an XPM file, it's tricker, since the elements of
|
|
|
1375 the pixmap don't represent FG and BG, but are actual
|
|
|
1376 pixel values. So we need to figure out which of those
|
|
|
1377 pixels is the foreground color and which is the
|
|
|
1378 background. We do it by comparing RGB and assuming
|
|
|
1379 that the darker color is the foreground. This works
|
|
|
1380 with the result of xbmtopbm|ppmtoxpm, at least.
|
|
185
|
1381
|
|
0
|
1382 It might be nice if there was some way to tag the
|
|
|
1383 colors in the XPM file with whether they are the
|
|
|
1384 foreground - perhaps with logical color names somehow?
|
|
185
|
1385
|
|
0
|
1386 Once we have decided which color is the foreground, we
|
|
|
1387 need to ensure that that color corresponds to a `1' bit
|
|
|
1388 in the Pixmap. The XPM library wrote into the (1-bit)
|
|
|
1389 pixmap with XPutPixel, which will ignore all but the
|
|
|
1390 least significant bit.
|
|
185
|
1391
|
|
0
|
1392 This means that a 1 bit in the image corresponds to
|
|
|
1393 `fg' only if `fg.pixel' is odd.
|
|
185
|
1394
|
|
0
|
1395 (This also means that the image will be all the same
|
|
|
1396 color if both `fg' and `bg' are odd or even, but we can
|
|
|
1397 safely assume that that won't happen if the XPM file is
|
|
|
1398 sensible I think.)
|
|
185
|
1399
|
|
0
|
1400 The desired result is that the image use `1' to
|
|
|
1401 represent the foreground color, and `0' to represent
|
|
|
1402 the background color. So, we may need to invert the
|
|
|
1403 image to accomplish this; we invert if fg is
|
|
|
1404 odd. (Remember that WhitePixel and BlackPixel are not
|
|
|
1405 necessarily 1 and 0 respectively, though I think it
|
|
|
1406 might be safe to assume that one of them is always 1
|
|
|
1407 and the other is always 0. We also pretty much need to
|
|
|
1408 assume that one is even and the other is odd.)

1801 and take that as meaning "couldn't convert."

1804 an error message on stderr. You can't make it not do that.

1805
