This utility scales an image or volume to a given size. A selection file can also be scaled and then all images/volumes in the selfile are scaled to the desired size.

$ scale -i ...

Parameters

• __OR__ Scale a single file

• __OR__ If no output file is given, then the input one is rewritten

• `` Scale of a bunch of files

• `` If no output extension is given, then the input ones are rewritten.

• `` Do not produce on screen information

• `` Output dimension along X axis

• -ydim [new Ynew X] = Output dimension along Y axis. If it is not given, it is assumed to be the same as the X one

• -zdim [new Znew X] = Output dimension along Z axis. If it is not given, it is assumed to be the same as the X one

• `` Scale factor, e.g., to reduce the image to an 80% of the original size, give 0.8. To enlarge the images, use a factor greater than 1

Scale a single image, overwriting input images

$ scale -i g0ta0001.xmp -xdim 32 -ydim 64

Scale a selfile, a new extension is given to output images, ie, if input images are of the like ofg0ta0001.xmp, then the output ones will beg0ta0001.rev. All images are scaled to square 32x32 images

$ scale -i g0ta.sel -oext rev -xdim 32 

Scale a selfile to an 80% of its original size

$ scale -i g0ta.sel -oext rev -factor 0.8
