1 This directory provides bitmaps with the same size and naming
2 conventions as those distributed till xboard-3.**
3 These bitmaps are distributed under the GNU GENERAL PUBLIC LICENSE
6 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.
13 The MetaFont source of this font may be obtained from me
14 under the GNU GENERAL PUBLIC LICENSE.
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.

22 [Elmar supplied only 80, 64, and 40 pixel bitmaps]
26 The 21-pixel bitmaps are also based on Elmar's font, but I hand-tuned
27 them quite a bit. I converted them from the Metafont gf file by
28 running gftype and applying a C program of my own to the
29 human-readable output.
31 icon_white and icon_black were produced in the same way.
37 The 33, 45, 49, 54, and 58 pixel bitmaps are also based on Elmar's font.
38 They were converted using dopkbm.sh, followed by a manual pass with the
39 X bitmap editor to adjust the size (adding blank borders as needed) and
40 to hand-tune the pixels in a few cases where that was badly needed.
41 Here is some data that may be useful in later conversions:

73 32 133x133 116x124 none
76 In each case, fselch*.mf was formatted for 300 dpi. On Linux with the
77 Red Hat tetex-0.4pl8-9 package, this required mag=0.5. Example:
80 \mode=localfont; mag=0.5; input fselch8.mf
83 On Red Hat with tetex-0.9-6, mag=1.0 was needed instead.
86 \mode=localfont; mag=1.0; input fselch26.mf
