BoolToInt converts bool into 32-bit integer if b is true, then returns 1, else 0

func Color

func Color(rgba uint32) color.RGBA

Color converts an rgba uint32 to a colorEnabled.RGBA

func CreateFileAtPath

func CreateFileAtPath(pathToFile string, data []byte) bool

CreateFileAtPath creates file at path

func ExportToGif

func ExportToGif(images []*image.RGBA, delay int32) error

ExportToGif converts images area to GIF format and saves it under the path selected by user tutorial: http://tech.nitoyon.com/en/blog/2016/01/07/go-animated-gif-gen/

func Hex2RGB

func Hex2RGB(hex string) (r, g, b uint8, err error)

Hex2RGB converts haxadecimal string color into r, g, b

func RGB2Hex

func RGB2Hex(red, green, blue uint8) string

RGB2Hex converts RGB color into hexadecimal string

func SplitIntoLinesWithMaxWidth

func SplitIntoLinesWithMaxWidth(fullSentence string, maxChars int) []string

SplitIntoLinesWithMaxWidth splits the given string into lines considering the given maxChars

func Wrap

func Wrap(x, max int) int

Wrap integer to max: wrap(450, 360) == 90
