703 DEST_MASK specifies the mask of allowed image types.
|

|
704
|
|

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

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

716 in the error message.

185

0
|
1369 Once we have decided which color is the foreground, we
|
|
|
1370 need to ensure that that color corresponds to a `1' bit
|
|
|
1371 in the Pixmap. The XPM library wrote into the (1-bit)
|
|
|
1372 pixmap with XPutPixel, which will ignore all but the
|
|
|
1373 least significant bit.
|
|
185
|
1374
|
|
0
|
1375 This means that a 1 bit in the image corresponds to
|
|
|
1376 `fg' only if `fg.pixel' is odd.
|
|
185
|
1377
|
|
0
|
1378 (This also means that the image will be all the same
|
|
|
1379 color if both `fg' and `bg' are odd or even, but we can
|
|
|
1380 safely assume that that won't happen if the XPM file is
|
|
|
1381 sensible I think.)
|
|
185
|
1382
|
|
0
|
1383 The desired result is that the image use `1' to
|
|
|
1384 represent the foreground color, and `0' to represent
|
|
|
1385 the background color. So, we may need to invert the
|
|
|
1386 image to accomplish this; we invert if fg is
|
|
|
1387 odd. (Remember that WhitePixel and BlackPixel are not
|
|
|
1388 necessarily 1 and 0 respectively, though I think it
|
|
|
1389 might be safe to assume that one of them is always 1
|
|
|
1390 and the other is always 0. We also pretty much need to
|
|
|
1391 assume that one is even and the other is odd.)

1787 an error message on stderr. You can't make it not do that.

1788
