scale2x - Scale an image using the Scale2x algorithm


    % scale2x [-x scale] file.png > file2.png


This utility allows you to scale an image using the Scale2x algorithm. It takes in an image of any format that GD understands and outputs a png. You can specify an integer value by which your image should be scaled (default: 2). Example:

    # scale4x
    % scale2x -x 4 file.png > file4x.png
