The Save and Encode functions are just thin wrappers around other packages (image/jpeg, image/png, etc). You can pass additional options to these packages to reduce the output image size. For example:

err = imaging.Save(img, "out.png", imaging.PNGCompressionLevel(png.BestCompression))
err = imaging.Save(img, "out.jpg", imaging.JPEGQuality(50))

The imaging package itself does not provide any other options to reduce image file size.

Hi:

I tried your method ,this method can not work well, the narrow picture's size is bigger than origin.
