* raylib [text] example - font loading
|
|
*
|
|
* Example complexity rating: [★☆☆☆] 1/4
|
|
*
|
|
* NOTE: raylib can load fonts from multiple input file formats:
|
|
*
|
|
* - TTF/OTF > Sprite font atlas is generated on loading, user can configure
|
|
* some of the generation parameters (size, characters to include)
|
|
* - BMFonts > Angel code font fileformat, sprite font image must be provided
|
|
* together with the .fnt file, font generation cna not be configured
|
|
* - XNA Spritefont > Sprite font image, following XNA Spritefont conventions,
|
|
* Characters in image must follow some spacing and order rules
|
|
*
|
|
* Example originally created with raylib 1.4, last time updated with raylib 3.0
|
|
*
|
|
* Example licensed under an unmodified zlib/libpng license, which is an OSI-certified,
|
|
* BSD-like license that allows static linking with closed source software
