Originally from C Library:
|
|
Karl Bartel
|
|
|
|
* SFONT - SDL Font Library by Karl Bartel <karlb@gmx.net> *
|
|
* *
|
|
* All functions are explained below. There are two versions of each *
|
|
* funtction. The first is the normal one, the function with the *
|
|
* 2 at the end can be used when you want to handle more than one font *
|
|
* in your program. *
|
|
* *
|
|
|
|
Copied into a C++ object to allow multiple fonts by:
|
|
Luc-Olivier de Charriere
|
|
|
|
David Olofson <david@olofson.net>:
|
|
* Strings changed to 'const char *'
|
|
* Cursor tests first check if '|' is present.
|
|
* Shadowed variables fixed.
|
|
* Garbage data in spacing table fixed. (Thanks to
|
|
Andreas Spångberg for discovering this one!)
|
|
* Added ExtraSpace(). (Scaling support hack...)
|
|
* Disabled colorkeying. (Ruins some RGBA fonts!)
