TinyFont

TinyFont is a font/text package for TinyGo displays. It's heavily based on Adafruit's GFX library.

example

This package is experimental and may change in the future. It has not been optimized for speed or memory..

Faster compilation

During compilation, tinygo will go through all the font files in a package and them discard them if not used. To improve compilation time considerably, move the files you are going to use to a new package.

About the fonts

The fonts compiled here were just converted or made compatible, and the original authors should be given proper credit. Each font is under its own license, and while most of them are under an open license, there might be differences in its usage and conditions.

License

This project is licensed under the BSD 3-clause license, just like the Go project itself.

Functions

func DrawChar 

func DrawChar(display drivers.Displayer, font *Font, x int16, y int16, char byte, color color.RGBA)

DrawChar sets a single char in the buffer of the display

func DrawCharRotated 

func DrawCharRotated(display drivers.Displayer, font *Font, x int16, y int16, char byte, color color.RGBA, rotation Rotation)

DrawCharRotated sets a single char in the buffer of the display

func LineWidth 

func LineWidth(font *Font, text []byte) (innerWidth uint32, outboxWidth uint32)

func WriteLine 

func WriteLine(display drivers.Displayer, font *Font, x int16, y int16, text []byte, color color.RGBA)

WriteLine writes a string in the selected font in the buffer

func WriteLineColors 

func WriteLineColors(display drivers.Displayer, font *Font, x int16, y int16, text []byte, colors []color.RGBA)

WriteLineColors writes a string in the selected font in the buffer. Each char is in a different color if not enough colors are defined, colors are cycled.
