Re: [Freetype] Licence issues

[Thibault Jamme]

Hi,


Thank you very much to Edward and Antoine for getting back to me on the 
licences issue quickly and informatively. More on that soon.

Short answer: all works as whatever version I was using before
(1 year ago at least)

Long answer:

+ A lot of hair scratching as once compiled with the .ide file suitable for 
my  Borland C++ 5 compiler I got a library whose function names apparently 
lack a preceding underscore - although the option is correctly (ie. 
'Standardly') checked in your project.
This is in fact coming from your optimization setting (same as in the 
makefile.BC BTW for command line compilation) to use the register calling 
convention. This is fine and justified however my project uses standard 'C' 
calling convention.
When I changed my project to 'Register' then I got thrown out as I am using 
the qsort function which does NOT like being passed register type 
functions. This causes a fatal compile error.
So I had to (sniff) compile freetype with the C calling convention.

Does anyone know if I can glue together a Register based lib to a C based 
project? Otherwise mentioning that issue in the Howto would be a good idea.

+ The ide project compiles to freetype.lib whereas the makefile.BC compiles 
to  libttf.lib. Is this what was intended?

+ I tested by dumping all the fonts in my Winnt fonts directory onto a bitmap.
  See: http://www.aptilis.com/freetype/test.gif

  Keeping in mind that:
  - The Tooneyno font does not appear to define lower case letters
    (I checked in Paintbbrush)

  - I do not do anything with cmaps and use a dirty cast or simple ASCII 
code transcription to get the glyph index. ie. opens___.ttf is most 
probably my fault.

  - I have auto-hinting enabled. I'm in the UK: software patents don't apply.
    (Yet?)

+ The Aptilis code that generates the bitmap can be seen at the bottom of 
this message. If anyone wants the latest build, ask me and I'll send it to 
you. The user's guide is at: http://www.aptilis.com/
