Functions

func ConvertToAscii

func ConvertToAscii(imgSet [][]AsciiPixel, negative bool, colored bool, complex bool, customMap string) [][]AsciiChar

Converts the 2D AsciiPixel slice of image data (each instance representing each pixel of original image) to a 2D AsciiChar slice with each colored and simple string having an ASCII character corresponding to the original grayscale and RGB values in AsciiPixel.

If complex parameter is true, values are compared to 69 levels of color density in ASCII characters. Otherwise, values are compared to 10 levels of color density in ASCII characters.

func ConvertToAsciiPixels

func ConvertToAsciiPixels(img image.Image, dimensions []int, flipX, flipY bool) ([][]AsciiPixel, int, int, error)

This function shrinks the passed image according to passed dimensions or terminal size if none are passed. Stores each pixel's grayscale and RGB values in an AsciiPixel instance to simplify getting numeric data for ASCII character comparison.

The returned 2D AsciiPixel slice contains each corresponding pixel's values. Grayscale value ranges from 0 to 65535, while RGB values are separate.

Types

type AsciiChar

type AsciiChar struct {
	Colored  string

}

type AsciiPixel

type AsciiPixel struct {
	// contains filtered or unexported fields
}
