A font resource to render text in bitmaps. A font is a combination of a font file name and a size. Supports true type font files (cf https://github.com/nothings/stb/blob/master/stb_truetype.h). The font size is automatically scaled based on the resolution, from a base resolution of 1920x1080 (14 is 14 pixels height in this resolution)

Creates a font resource
- Parameters
-
| path | : font file path, relative to the application working directory |
| size | : height in pixels on a base resolution of 1920x1080 |
| const auto& getFontName |
( |
| ) |

|
nodiscardinline |
Returns the font path. Useful to create another Font resource with a different size
| auto getFontSize |
( |
| ) |
const |
|
nodiscardinline |
Returns the font height in pixels (NOT scaled size, but the size given to the Font constructor)
| void getSize |

nodiscard |
Renders a string into an RGBA bitmap (stored in CPU memory). Glyphs are white with alpha channel mapped to the glyphs geometry
- Parameters
-
| text | : text to render |
| wwidth | : width of the resulting bitmap |
| hheight | : height of the resulting bitmap |
- Returns
- 32 bits RGBA bitmap stored in CPU memory
