GD::Graph cannot change font

kp2a has asked for the wisdom of the Perl Monks concerning the following question:

I cannot change font or size for labels etc.
For example from GD::Graph sample95.pl (modified)
(It is included in the build directory of the distribution.)

    my $font_spec = "Dustismo_Sans";

    $my_graph->set_y_label_font($font_spec, 12);
    $my_graph->set_x_label_font($font_spec, 12);
    $my_graph->set_y_axis_font($font_spec, 10);
    $my_graph->set_x_axis_font($font_spec, 36);
    $my_graph->set_title_font($font_spec, 48);
    $my_graph->set_legend_font($font_spec, 8);
    $my_graph->set_values_font($font_spec, 8);

Dustismo_Sans.ttf is in pwd. And I have tried "Dustismo_Sans" and "Dustismo_Sans.ttf" and "/home/john/Dustismo_Sans.ttf" for $font_spec

Whatever I put in $font_spec or in the size field, the appearance of the resulting image is always the same!

Questions:

1. I assume that GD would look for the font file given a relative (to pwd) file name or an absolute file name. Correct?

2. Why can I not change size or font?

3. My OS is FC 8. I loaded msttcorefonts-2.0-1.spec, Microsoft TTL fonts, and they are usable by OpenOffice but I cannot locate corresponding .ttf files. Do they exist as such and if so, where are they?

Thanks

Try like this `$my_graph->set_y_label_font($font_spec, 12) or warn $my_graph->error;` [download] Hopefully there will be a warning	[reply] [d/l]
