Function newImage

transform_test.go:33–43

newImage creates a new NRGBA image with the specified dimensions and pixel color data. If the length of pixels is 1, the entire image is filled with that color.

(w, h int, pixels ...color.Color)

// color data.  If the length of pixels is 1, the entire image is filled with
// that color.
