ImageProcessor is a tool to manipulate images

func NewImageProcessor

func NewImageProcessor() *ImageProcessor

NewImageProcessor creates an instance of `ImageProcessor` (image manipulation tool).

func (*ImageProcessor) Resize

func (proc *ImageProcessor) Resize(
	in io.Reader,
	out io.Writer,
	toWidth, toHeight uint,
) (imageFormat imageprocessorcommon.ImageFormat, err error)

Resize reads an image from `in` and writes a resized image to `out` (new image size: `toWidth`x`toHeight`).

It returns image format and (if occured:) an error.
