Converting OpenType Fonts
Conversion of OpenType TT and OpenType PS fonts to the traditional
Type 1 and TrueType formats is of no interest because this will just strip
out all additional OpenType-specific information from the font. This is
possible but not a very useful operation. The more useful types of
conversion are as follows:
1. Conversion of OpenType TT fonts to OpenType PS fonts and vice versa.
This can be called "changing the font flavor".
2. Conversion of traditional Type 1 and TrueType fonts to OpenType
fonts.
OpenType PS Options
To check and set parameters for generating OpenType fonts, click
the Preferences button at the bottom of the Main Window and refer to the
Generate OpenType PS Page of the Preferences dialog:
Generate OpenType PS Page of the Preferences Dialog
There are only two controls in the dialog which are used to customize the
OpenType font generating process.
The glyph outlines in OpenType PS fonts can be compressed. If the Use
subroutines to compress outlines option is checked, TransType Pro
will perform this compression. This option is on by default.
