This directory provides bitmaps with the same size and naming

conventions as those distributed till xboard-3.**

The bitmaps contained herein were converted from my MetaFont
7
version of chess font. These are designed very well to deliver
8
good rastered images on low resolution devices. The general
9
shape of these fonts are designed after very old typefaces
10
used in printing chess books. They are not as fancy as the
11
currently used bitmaps of xboard, but I like them in their
12
'san serif'-ness - may be others too.

The MetaFont source of this font may be obtained from me

15
To convert the pk-Files to bitmaps I used the conversion tool
16
mftobdf to generate X11-bdf - fonts, and then used a small C
17
program, to write the xbm-files.

The 21-pixel bitmaps are also based on Elmar's font, but I hand-tuned
25
them quite a bit. I converted them from the Metafont gf file by
26
running gftype and applying a C program of my own to the
27
human-readable output.
29
icon_white and icon_black were produced in the same way.
35
I took the x40x.bm files from Tim's Xboard/bitmap distribution and modified
36
them so as to have the light and dark colored square pieces (dark squares have
37
the cross-hatching found in most chess books). Added empty squares.
39
The naming convention for the bitmaps is almost obvious. The first character
40
is the color of the square, the second is the color of the piece, and the
41
third is the piece abbreviation (english bias: p, r, n, b, q, k).
42
The blank squares are the only exception, they are simply wsq.bm and bsq.bm.
