1559 XCreatePixmapCursor() assumes this property of the

1561 color argument is used for the 1 bits.
|
|
|
1562
|
|
|
1563 With an XPM file, it's tricker, since the elements of
|
|
|
1564 the pixmap don't represent FG and BG, but are actual
|
|
|
1565 pixel values. So we need to figure out which of those
|
|
|
1566 pixels is the foreground color and which is the
|
|
|
1567 background. We do it by comparing RGB and assuming
|
|
|
1568 that the darker color is the foreground. This works
|
|
|
1569 with the result of xbmtopbm|ppmtoxpm, at least.
|

1570

0
|
1571 It might be nice if there was some way to tag the
|
|
|
1572 colors in the XPM file with whether they are the
|
|
|
1573 foreground - perhaps with logical color names somehow?
|
|
185
|
1574
|
|
0
|
1575 Once we have decided which color is the foreground, we
|
|
|
1576 need to ensure that that color corresponds to a `1' bit
|
|
|
1577 in the Pixmap. The XPM library wrote into the (1-bit)
|
|
|
1578 pixmap with XPutPixel, which will ignore all but the
|
|
|
1579 least significant bit.
|
|
185
|
1580
|
|
0
|
1581 This means that a 1 bit in the image corresponds to
|
|
|
1582 `fg' only if `fg.pixel' is odd.
|
|
185
|
1583
|
|
0
|
1584 (This also means that the image will be all the same
|
|
|
1585 color if both `fg' and `bg' are odd or even, but we can
|
|
|
1586 safely assume that that won't happen if the XPM file is
|
|
|
1587 sensible I think.)
|
|
185
|
1588
|
|
0
|
1589 The desired result is that the image use `1' to
|
|
|
1590 represent the foreground color, and `0' to represent
|
|
|
1591 the background color. So, we may need to invert the
|
|
|
1592 image to accomplish this; we invert if fg is
|
|
|
1593 odd. (Remember that WhitePixel and BlackPixel are not
|
|
|
1594 necessarily 1 and 0 respectively, though I think it
|
|
|
1595 might be safe to assume that one of them is always 1
|
|
|
1596 and the other is always 0. We also pretty much need to
|
|
|
1597 assume that one is even and the other is odd.)

2141 - When it can't convert the given string to a real cursor, it will

2142 sometimes return a "success" value, after triggering a BadPixmap
|
|
|
2143 error. It then gives you a cursor that will itself generate BadCursor
|
|
|
2144 errors. So we install this error handler to catch/notice the X error
|
|
|
2145 and take that as meaning "couldn't convert."
|
|
|
2146
|
|
|
2147 - When you tell it to find a cursor file that doesn't exist, it prints
|
|
|
2148 an error message on stderr. You can't make it not do that.
|
|
|
2149
|
|

2150 - Also, using Xmu means we can't properly hack Lisp_Image_Instance
|

2151 objects, or XPM files, or $XBMLANGPATH.
