This will scale the image by the amount specified: convert flower_original.jpeg -resize 50% half_flower.jpegįor most of us, this type of scaling will be perfectly fine, but we should note that the final pixel size of the image will be rounded to the nearest integer. Use the convert program to convert between image formats as well as resize an image, blur, crop, despeckle, dither, draw on, flip, join, re-sample. This topic discusses DISM commands related to image management. Similarly, we can also specify a percentage value when using the resize option.
