Summary: Corrupted BDFs generated when using fstobdf on a XFree86
xfs
Product: Fonts
Version: 4.1
OS/Version: Linux
Status: NEW
Severity: major
Priority: P2
Component: XFS
AssignedTo: [EMAIL PROTECTED]
ReportedBy: [EMAIL PROTECTED]
Using XFree86-xfs-4.1.0-3 (on RedHat Linux 7.2):
fstobdf generates a bad BDF font file when acessing a XFree86 xfs.
The BITMAP part of the character description are corrupted.
Consequently, re-generating a PCF from these BDFs (using bdftopcf) results in a
fully different and corrupted font.
The X Fonts Server is the buggy component, not fstobdf :
- using XFree86 fstobdf accessing a non-XFree86 X font Server generates a
correct BDF
- using XFree86 fstobdf accessing a XFree86 X font Server generates an incorrect
BDF
- using a non-XFree86 fstobdf accessing a XFree86 X font Server generates an
incorrect BDF
- using a non-XFree86 fstobdf accessing a non-XFree86 X font Server generates a
correct BDF
Note this could not be tested on a newer version of XFree86, as not available in
my company ...
APPENDIX 1 :
The configuration file used to start xfs is as follows
#
# Default font server configuration file for Red Hat Linux
#
# allow a max of 10 clients to connect to this font server
client-limit = 10
# when a font server reaches its limit, start up a new one
#clone-self = on
# alternate font servers for clients to use
#alternate-servers = foo:7101,bar:7102
# where to look for fonts
#
catalogue = /usr/X11R6/lib/X11/fonts/100dpi
# in 12 points, decipoints
default-point-size = 120
# 100 x 100 and 75 x 75
default-resolutions = 75,75,100,100
# use lazy loading on 16 bit (usually Asian) fonts
deferglyphs = 16
# how to log errors
use-syslog = on
# don't listen to TCP ports by default for security reasons
#no-listen = tcp
