SYNOPSIS

unslice [ -f ctlfile ] [ -y ymax ] [ -o outfile ] infiles ...

DESCRIPTION

Unslice quickly assembles a number of horizontal image strips into a single output image. A typical use for unslice is to put together portions of an image ("slices") computed independently into a single output picture. Because unslice uses the "raw" RLE library calls to read and write the images, it runs much faster than doing the equivalent operations with crop and comp.

unslice has two modes of operation. If given the -f flag, unslice reads a control file telling it how to assemble the images. This is a text file with two decimal numbers on each line, one line for each slice to be assembled into the output image. Each line gives the starting and stopping scanlines (inclusive) for each slice. These must be in ascending order. This is useful if the slices have excess image area that should be cropped away.

If no control file is given, the -y flag is used. This tells unslice what the maximum Y value of the output image is. Unslice reads the files in order, using the RLE headers to determine where to place the slices. If two slices overlap, the first scanlines from the second slice are thrown away. In both cases, the slices must be in ascending order, and are expected to be of uniform width.

BUGS

Unslice has really been superceded by rlepatch(1).
