Description Erik de Castro Lopo 2012-01-14 15:31:42 UTC

Created attachment 55587 [details]
Text program demonstrating the problem.

http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=655929

Attached very simple C program compiled and run as follows:

    gcc -Wall `pkg-config --cflags --libs cairo` test.c -o test && \
    ./test && \
    eog test.png 

produces incorrect results in Debian testing with libcairo2 1.10.2 and
correct results in Debian stable with libcario2 version 1.8.10.

The output file generated by the test program (test.png) has two
lines of text. There should be one line of large text and one line
of small text. With libcario2 from testing, both lines are the 
large size.

Do you actually have a terminus-30? I doubt it, so I believe the effect you are seeing is due to font substitution, the rules for which should be provided by fontconfig and not cairo itself.

Yes, you are right.

So what has changed between cairo 1.8.10 and cairo 1.10.2 that changes the font substitution? It works correctly with cairo 1.8.10.

Moving from Terminus to 'DejaVu Sans Mono' font fixed all my problems and DejaVu is probably more widely available.

Marking this as resolved.
