OSX Problem

Post by Fireplayer » Sun Jan 17, 2016 3:54 am

First of all I am a font newbie and and definitely not knowledgeable about font specifics.
I have a True Type font I purchased a while back and it works fine on Windows. I have opened it FontCreator and saved it with no problems.

I have installed it on a Mac and the font installs fine.
When I try to make it bold or italic in an OS X application I am writing, it dos not work. When calling CTFontCreateCopyWithSymbolicTraits with bold or italic, the returned font reference in null. Anybody know what is happening?

There should have been no reason to modify the font for OSX. It also may not be permitted in the user agreement.

You need to have the distinct styles. So a normal, bold, italic and so on.

From this thread on Stack Overflow, it looks as though CTFontCreateCopyWithSymbolicTraits() does exactly what its name suggests: in other words, it creates faux fonts for the bold and italic styles, so no editing of the original font file is needed. I guess it's just a matter of making sure that you get the parameters right, but (as with all faux fonts) the results will generally not be as good as using a separate font file for each of the additional styles.
