1364 /* With an XBM file, it's obvious which bit is foreground
|
|
|
1365 and which is background, or rather, it's implicit: in
|
|
|
1366 an XBM file, a 1 bit is foreground, and a 0 bit is
|
|

1367 background.

1369 XCreatePixmapCursor() assumes this property of the
|
|
|
1370 pixmap it is called with as well; the `foreground'
|
|
|
1371 color argument is used for the 1 bits.
|
|
|
1372
|
|
|
1373 With an XPM file, it's tricker, since the elements of
|
|
|
1374 the pixmap don't represent FG and BG, but are actual
|
|
|
1375 pixel values. So we need to figure out which of those
|
|
|
1376 pixels is the foreground color and which is the
|
|
|
1377 background. We do it by comparing RGB and assuming
|
|
|
1378 that the darker color is the foreground. This works
|
|
|
1379 with the result of xbmtopbm|ppmtoxpm, at least.
|

|
1380

|
1381 It might be nice if there was some way to tag the
|
|
|
1382 colors in the XPM file with whether they are the
|
|
|
1383 foreground - perhaps with logical color names somehow?
|
|
185
|
1384
|
|
0
|
1385 Once we have decided which color is the foreground, we
|
|
|
1386 need to ensure that that color corresponds to a `1' bit
|
|
|
1387 in the Pixmap. The XPM library wrote into the (1-bit)
|
|
|
1388 pixmap with XPutPixel, which will ignore all but the
|
|
|
1389 least significant bit.
|
|
185
|
1390
|
|
0
|
1391 This means that a 1 bit in the image corresponds to
|
|
|
1392 `fg' only if `fg.pixel' is odd.
|
|
185
|
1393
|
|
0
|
1394 (This also means that the image will be all the same
|
|
|
1395 color if both `fg' and `bg' are odd or even, but we can
|
|
|
1396 safely assume that that won't happen if the XPM file is
|
|
|
1397 sensible I think.)
|
|
185
|
1398
|
|
0
|
1399 The desired result is that the image use `1' to
|
|
|
1400 represent the foreground color, and `0' to represent
|
|
|
1401 the background color. So, we may need to invert the
|
|
|
1402 image to accomplish this; we invert if fg is
|
|
|
1403 odd. (Remember that WhitePixel and BlackPixel are not
|
|
|
1404 necessarily 1 and 0 respectively, though I think it
|
|
|
1405 might be safe to assume that one of them is always 1
|
|
|
1406 and the other is always 0. We also pretty much need to
|
|
|
1407 assume that one is even and the other is odd.)

1730 sometimes return a "success" value, after triggering a BadPixmap
|

1731 error. It then gives you a cursor that will itself generate BadCursor
|
|
|
1732 errors. So we install this error handler to catch/notice the X error
|
|
|
1733 and take that as meaning "couldn't convert."
|
|
|
1734
|
|
|
1735 - When you tell it to find a cursor file that doesn't exist, it prints
|
|
|
1736 an error message on stderr. You can't make it not do that.
|
|
|
1737
|

1738 - Also, using Xmu means we can't properly hack Lisp_Image_Instance
