773 and which is background, or rather, it's implicit: in

|
774 an XBM file, a 1 bit is foreground, and a 0 bit is
|
|
|
775 background.
|
|
|
776
|
|
|
777 XCreatePixmapCursor() assumes this property of the
|
|
|
778 pixmap it is called with as well; the `foreground'
|
|
|
779 color argument is used for the 1 bits.
|
|
|
780
|
|
|
781 With an XPM file, it's tricker, since the elements of
|
|
|
782 the pixmap don't represent FG and BG, but are actual
|
|
|
783 pixel values. So we need to figure out which of those
|
|
|
784 pixels is the foreground color and which is the
|
|
|
785 background. We do it by comparing RGB and assuming
|
|
|
786 that the darker color is the foreground. This works
|
|
|
787 with the result of xbmtopbm|ppmtoxpm, at least.
|
|
|
788
|
|
|
789 It might be nice if there was some way to tag the
|
|
|
790 colors in the XPM file with whether they are the
|
|
|
791 foreground - perhaps with logical color names somehow?
|
|
|
792
|
|
|
793 Once we have decided which color is the foreground, we
|
|
|
794 need to ensure that that color corresponds to a `1' bit
|
|
|
795 in the Pixmap. The XPM library wrote into the (1-bit)
|
|
|
796 pixmap with XPutPixel, which will ignore all but the
|
|
|
797 least significant bit.
|
|
|
798
|
|
|
799 This means that a 1 bit in the image corresponds to
|
|
|
800 `fg' only if `fg.pixel' is odd.
|
|
|
801
|
|
|
802 (This also means that the image will be all the same
|
|
|
803 color if both `fg' and `bg' are odd or even, but we can
|
|
|
804 safely assume that that won't happen if the XPM file is
|
|
|
805 sensible I think.)
|
|
|
806
|
|
|
807 The desired result is that the image use `1' to
|
|
|
808 represent the foreground color, and `0' to represent
|
|
|
809 the background color. So, we may need to invert the
|
|
|
810 image to accomplish this; we invert if fg is
|
|
|
811 odd. (Remember that WhitePixel and BlackPixel are not
|
|
|
812 necessarily 1 and 0 respectively, though I think it
|
|
|
813 might be safe to assume that one of them is always 1
|
|
|
814 and the other is always 0. We also pretty much need to
|
|
|
815 assume that one is even and the other is odd.)

1827 an error message on stderr. You can't make it not do that.

|
|

2956 1. It makes the assumption that you can detect whether the user
|
|
|
2957 wanted a cursor or a string based on the data, since the data is a
|
|
|
2958 string you have to prioritise cursors. Instead we will force users
|
|
|
2959 to pick the appropriate image type, this is what we do under
|
|
|
2960 MS-Windows anyway.
|
|
|
2961 2. It doesn't fit with the new domain model - you cannot tell which
|
|
|
2962 domain it needs to be instantiated in until you've actually
|
|
|
2963 instantiated it, which mucks up caching.
|
|
|
2964 3. It only copes with cursors and strings which seems bogus. */
