104 /// NK_INCLUDE_DEFAULT_FONT | Defining this adds the default font: ProggyClean.ttf into this library which can be loaded into a font atlas and allows using this library without having a truetype font
3754 different ways to use the font atlas. The first two will use your font
3791 `nk_user_font`. First a texture atlas handle used to draw text as subimages
3792 of a bigger font atlas texture and a callback to query a character's glyph
3830 The font baker APIs can be used to create a font plus font atlas texture
3848 inside the font atlas and allows to reuse the font atlas. If you don't want to reuse
3857 will free all temporary memory including the font atlas image so make sure
3863 At this point you are done and if you don't want to reuse the font atlas you
3865 memory. Finally if you don't use the font atlas and any of it's fonts anymore
