701 DEST_MASK specifies the mask of allowed image types.
|

|
702
|
|

703 PIXELS and NPIXELS specify an array of pixels that are used in
|
|
|
704 the image. These need to be kept around for the duration of the

|
705 image. When the image instance is freed, XFreeColors() will
|
|
|
706 automatically be called on all the pixels specified here; thus,
|
|
|
707 you should have allocated the pixels yourself using XAllocColor()
|
|
|
708 or the like. The array passed in is used directly without
|
|
|
709 being copied, so it should be heap data created with xmalloc().
|
|
|
710 It will be freed using xfree() when the image instance is
|
|
|
711 destroyed.

714 in the error message.

1355 With an XPM file, it's tricker, since the elements of

1359 background. We do it by comparing RGB and assuming

1360 that the darker color is the foreground. This works

1368 need to ensure that that color corresponds to a `1' bit
|
|
|
1369 in the Pixmap. The XPM library wrote into the (1-bit)
|
|
|
1370 pixmap with XPutPixel, which will ignore all but the
|
|
|
1371 least significant bit.
|
|
185
|
1372
|
|
0
|
1373 This means that a 1 bit in the image corresponds to
|
|
|
1374 `fg' only if `fg.pixel' is odd.
|
|
185
|
1375
|
|
0
|
1376 (This also means that the image will be all the same
|
|
|
1377 color if both `fg' and `bg' are odd or even, but we can
|
|
|
1378 safely assume that that won't happen if the XPM file is
|
|
|
1379 sensible I think.)
|
|
185
|
1380
|
|
0
|
1381 The desired result is that the image use `1' to
|
|
|
1382 represent the foreground color, and `0' to represent
|
|
|
1383 the background color. So, we may need to invert the
|
|
|
1384 image to accomplish this; we invert if fg is
|
|
|
1385 odd. (Remember that WhitePixel and BlackPixel are not
|
|
|
1386 necessarily 1 and 0 respectively, though I think it
|
|
|
1387 might be safe to assume that one of them is always 1
|
|
|
1388 and the other is always 0. We also pretty much need to
|
|
|
1389 assume that one is even and the other is odd.)

1781 errors. So we install this error handler to catch/notice the X error

1782 and take that as meaning "couldn't convert."
|

1783
|
|
|
1784 - When you tell it to find a cursor file that doesn't exist, it prints
|
|
|
1785 an error message on stderr. You can't make it not do that.
|
|
|
1786
