|
* raylib [text] example - font spritefont
|
|
*
|
|
* Example complexity rating: [★☆☆☆] 1/4
|
|
*
|
|
* NOTE: Sprite fonts should be generated following this conventions:
|
|
*
|
|
* - Characters must be ordered starting with character 32 (Space)
|
|
* - Every character must be contained within the same Rectangle height
|
|
* - Every character and every line must be separated by the same distance (margin/padding)
|
|
* - Rectangles must be defined by a MAGENTA color background
|
|
*
|
|
* Following those constraints, a font can be provided just by an image,
|
|
* this is quite handy to avoid additional font descriptor files (like BMFonts use)
|
|
*
|
|
* Example originally created with raylib 1.0, last time updated with raylib 1.0
|
|
*
|
|
* Example licensed under an unmodified zlib/libpng license, which is an OSI-certified,
|
|
* BSD-like license that allows static linking with closed source software
