This directory provides bitmaps with the same size and naming
conventions as those distributed till xboard-3.**
These bitmaps are distributed under the GNU GENERAL PUBLIC LICENSE
coming with xboard.
The bitmaps contained herein were converted from my MetaFont
version of chess font. These are designed very well to deliver
good rastered images on low resolution devices. The general
shape of these fonts are designed after very old typefaces
used in printing chess books. They are not as fancy as the
currently used bitmaps of xboard, but I like them in their
'san serif'-ness - may be others too.
The MetaFont source of this font may be obtained from me
under the GNU GENERAL PUBLIC LICENSE.
To convert the pk-Files to bitmaps I used the conversion tool
mftobdf to generate X11-bdf - fonts, and then used a small C
program, to write the xbm-files.

The 21-pixel bitmaps are also based on Elmar's font, but I hand-tuned
them quite a bit. I converted them from the Metafont gf file by
running gftype and applying a C program of my own to the
human-readable output.
icon_white and icon_black were produced in the same way.

I took the x40x.bm files from Tim's Xboard/bitmap distribution and modified
them so as to have the light and dark colored square pieces (dark squares have
the cross-hatching found in most chess books). Added empty squares.
The naming convention for the bitmaps is almost obvious. The first character
is the color of the square, the second is the color of the piece, and the
third is the piece abbreviation (english bias: p, r, n, b, q, k).
The blank squares are the only exception, they are simply wsq.bm and bsq.bm.
