Functions

func CreateTextBubble

func CreateTextBubble(width, height float64, inputText string, size float64) image.Image

func CreateTextImg

func CreateTextImg(inputText string, width, height, size float64, c color.Color) image.Image

func DrawRoundedRectangleThoughtBubble

func DrawRoundedRectangleThoughtBubble(dc *gg.Context, x, y, w, h, r float64)

Expanded version of gg.Context.DrawRoundedRectangle(...)

func Lerp

func Lerp(a, b, ratio float64) float64

The ratio is capped between 0 and 1

func LerpColor

func LerpColor(a, b color.RGBA, ratio float64) color.RGBA

Creates a color between the given a and b. 0 means a is given, 1 means b is given, .5 is a color half way between. The ratio is capped between 0 and 1 Currently the function floors the number instead of rounding to nearest.

func LerpUint8

func LerpUint8(a, b uint8, ratio float64) uint8

The ratio is capped between 0 and 1 Currently the function floors the number instead of rounding to nearest.
