DESCRIPTION
imgcvt converts an image or a sequence to a different image
format. The input and output image formats are usually
determined by filename extension or image content. However,
when the input or output image has no extension, or does not
contain an identifiable tag, the -f and -t options can be
used to select the desired formats.
When working on a sequence of images, the # and @ symbols are
used to reference the current frame number. # indicates a
four-digits padded number, wheras @ indicates a non padded
number. The following converts a sequence of 100 frames:
imgcvt -n 1 100 1 image_in.tdi.@ image_out.#.rla
For more precise control of the frame number format, use
either multiple @ symbols to set a specific padding or use
the standard printf(3S) notation:
imgcvt -n 1 100 1 image_in.@@@.rgb image_out.#.rla
imgcvt -n 1 100 1 image_in.%03d.rgb image_out.#.rla
imgcvt -n 1 100 1 image_in.%.2f.rgb image_out.#.rla
Simple input and output sequences can be specified with -n
and -N. Use -r and -R for more complex sequences, like
discontinuous sets of frames. A sequence specifier is a list
of single frames or ranges separated by a , or a /. For each
range, an optional step can be specified after a x:
imgcvt -r 1-5 ...
imgcvt -r 1-5x2 ...
imgcvt -r 1-5,10-20x2,50 ...
Sequences can be reversed and offsets can be added to the
input or output frame number:
imgcvt -r 100-1 -R 1-100 in.#.rgb out.#.rla
imgcvt -r 1-100 in.#.rgb out.#+100.rla
