[scribus] Font::TTFMetrics error - font metrics

[andrew james]

Malay,

Though you had not responded, I continued to try solutions to the 
problem.  The one variant was the font.  The file georgia.ttf returns 
values, though I have not decoded font-units for my use, no errors.  
georgia.ttf is attached.

As your program is dated 2003, I think you may have concern to know that 
some fonts err.  I attached the file DejaVuSerif.ttf that errs as 
described pre.

I suggest the cause is some untested fonts are in code that defies your 
programs algorithms.

If you please, state your intent to maintain your code.  Explain briefly 
details to the error for font DejaVuSerif.ttf.  Perhaps someone else 
will maintain the code, that others may use more fully.

For example, project scribus has multiple request for functions that 
measure fonts.


Attached is the example-character-width.pl perl program that works to 
calculate the width of character 'a' font georgia.ttf

regard,
Andrew
