1371 XCreatePixmapCursor() assumes this property of the

1372 pixmap it is called with as well; the `foreground'
|

|
1373 color argument is used for the 1 bits.
|
|
|
1374
|
|
|
1375 With an XPM file, it's tricker, since the elements of
|
|
|
1376 the pixmap don't represent FG and BG, but are actual
|
|
|
1377 pixel values. So we need to figure out which of those
|
|
|
1378 pixels is the foreground color and which is the
|
|
|
1379 background. We do it by comparing RGB and assuming
|
|
|
1380 that the darker color is the foreground. This works
|
|
|
1381 with the result of xbmtopbm|ppmtoxpm, at least.
|
|
185
|
1382

0
|
1383 It might be nice if there was some way to tag the
|
|
|
1384 colors in the XPM file with whether they are the
|
|
|
1385 foreground - perhaps with logical color names somehow?
|
|
185
|
1386
|
|
0
|
1387 Once we have decided which color is the foreground, we
|
|
|
1388 need to ensure that that color corresponds to a `1' bit
|
|
|
1389 in the Pixmap. The XPM library wrote into the (1-bit)
|
|
|
1390 pixmap with XPutPixel, which will ignore all but the
|
|
|
1391 least significant bit.
|
|
185
|
1392
|
|
0
|
1393 This means that a 1 bit in the image corresponds to
|
|
|
1394 `fg' only if `fg.pixel' is odd.
|
|
185
|
1395
|
|
0
|
1396 (This also means that the image will be all the same
|
|
|
1397 color if both `fg' and `bg' are odd or even, but we can
|
|
|
1398 safely assume that that won't happen if the XPM file is
|
|
|
1399 sensible I think.)
|
|
185
|
1400
|
|
0
|
1401 The desired result is that the image use `1' to
|
|
|
1402 represent the foreground color, and `0' to represent
|
|
|
1403 the background color. So, we may need to invert the
|
|
|
1404 image to accomplish this; we invert if fg is
|
|
|
1405 odd. (Remember that WhitePixel and BlackPixel are not
|
|
|
1406 necessarily 1 and 0 respectively, though I think it
|
|
|
1407 might be safe to assume that one of them is always 1
|
|
|
1408 and the other is always 0. We also pretty much need to
|
|
|
1409 assume that one is even and the other is odd.)

1731 - When it can't convert the given string to a real cursor, it will

1732 sometimes return a "success" value, after triggering a BadPixmap
|

1733 error. It then gives you a cursor that will itself generate BadCursor

1734 errors. So we install this error handler to catch/notice the X error
|
|
|
1735 and take that as meaning "couldn't convert."
|
|
|
1736
|
|
|
1737 - When you tell it to find a cursor file that doesn't exist, it prints
|
|
|
1738 an error message on stderr. You can't make it not do that.
|
|
|
1739
|

1740 - Also, using Xmu means we can't properly hack Lisp_Image_Instance
|

1741 objects, or XPM files, or $XBMLANGPATH.
