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.

func WriteLineColorsRotated

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

WriteLineColorsRotated 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.

func WriteLineRotated

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

WriteLineRotated writes a string in the selected font in the buffer
