Usage:
1. Load a font and place it in an SDL_Surface *. If your are using the
SDL_image library you can do this with Font=IMG_Load("filename");
2. Initialize the font by using InitFont(surface *Font);
3. Now you can use the font in you SDL program.
Please take a look at SFont.h to get info about the funtions.
FileFormat:
The font file can be any type image file. The characters start with
ASCII symbol #33. They are seperated by pink(255,0,255) lines at the top
of the image. The space between these lines is the width of the caracter.
Just take a look at the font, and you'll be able to understand what I tried
to explain here.
The easiest way to create a new font is to use the GIMP's Logo function.
Use the following string as text (ASCII 33-127 with escape sequences and
spaces between the letters):
! \" # $ % & ' ( ) * + , - . / 0 1 2 3 4 5 6 7 8 9 : ; < = > ? @ A B C D E F G H I J K L M N O P Q R S T U V W X Y Z [ \\ ] ^ _ ` a b c d e f g h i j k l m n o p q r s t u v w x y z { | } ~
Example for the font file format:
____ _____ _____ _____ <- This is the pink line at the top
# ##### ####
# # # # #
# # # # #
# # ##### #
##### # # #
# # # # #
# # ##### ####
