NAME

autoextract - generate a csh script file to automatically extract smaller images from a larger HIPS image  

SYNOPSIS

autoextract <-f file> <-s x y OR -p r c> [-q] > outfile  

DESCRIPTION

Autoextract generates a c shell script, (sent to the standard output), to extract sub-images from a large HIPS image. It will work with HIPS images of the following formats: byte, short, int, float, complex, double, and double complex.

Regardless of input specifications, the output images created by executing the script will be named with the following name convention: infile.row.col, where row and col represent the location of the sub-image in reference to its location on the original image. By HIPS convention, the upper left represents a row and col of zero.  

OPTIONS

-f
specify the large image input file. This image file must be available to autoextract so that sizing information can be obtained.
-s
set the size of the sub-images by specifying the number of pixels along the x (horizontal) and y (vertical) directions. A size that breaks the large image into a non-integer number of equally sized sub-images will result in one or more of the sub-images being smaller than the size requested.
-p
this option lets the user select the number of rows and columns to break the large image into. Sub-image pixel size is then automatically computed.
-q
put the sub-images into a sequence named infile.seq
