| 777 and which is background, or rather, it's implicit: in | |
| 778 an XBM file, a 1 bit is foreground, and a 0 bit is | |
| 779 background. | |
| 780 | |
| 781 XCreatePixmapCursor() assumes this property of the | |
| 782 pixmap it is called with as well; the `foreground' | |
| 783 color argument is used for the 1 bits. | |
| 784 | |
| 785 With an XPM file, it's tricker, since the elements of | |
| 786 the pixmap don't represent FG and BG, but are actual | |
| 787 pixel values. So we need to figure out which of those | |
| 788 pixels is the foreground color and which is the | |
| 789 background. We do it by comparing RGB and assuming | |
| 790 that the darker color is the foreground. This works | |
| 791 with the result of xbmtopbm|ppmtoxpm, at least. | |
| 792 | |
| 793 It might be nice if there was some way to tag the | |
| 794 colors in the XPM file with whether they are the | |
| 795 foreground - perhaps with logical color names somehow? | |
| 796 | |
| 797 Once we have decided which color is the foreground, we | |
| 798 need to ensure that that color corresponds to a `1' bit | |
| 799 in the Pixmap. The XPM library wrote into the (1-bit) | |
| 800 pixmap with XPutPixel, which will ignore all but the | |
| 801 least significant bit. | |
| 802 | |
| 803 This means that a 1 bit in the image corresponds to | |
| 804 `fg' only if `fg.pixel' is odd. | |
| 805 | |
| 806 (This also means that the image will be all the same | |
| 807 color if both `fg' and `bg' are odd or even, but we can | |
| 808 safely assume that that won't happen if the XPM file is | |
| 809 sensible I think.) | |
| 810 | |
| 811 The desired result is that the image use `1' to | |
| 812 represent the foreground color, and `0' to represent | |
| 813 the background color. So, we may need to invert the | |
| 814 image to accomplish this; we invert if fg is | |
| 815 odd. (Remember that WhitePixel and BlackPixel are not | |
| 816 necessarily 1 and 0 respectively, though I think it | |
