This is not a big deal for me. I was just trying to help someone else on a problem which needs to be able to output in text format run length encoded data. So I tried the following as a first step, but got the following error message.


convert tree.gif -colors 8 -depth 8 tree.rle
convert: delegate failed `"rawtorle" -o "%o" -v "%i"' @ error/delegate.c/InvokeDelegate/1065.

The interesting this is that I had just previously installed NetPBM package via MacPorts and can successfully do

convert tree.gif -colors 8 -depth 8 tree.pnm
pnmtorle tree.pnm -o tree.rle

However, when I search http://netpbm.sourceforge.net/doc/directory.html, I can find no sign of a rawtorle NetPBM package.


EDIT: Looks like it needs rawtorle from the Utah Raster Toolkit and not from NetPBM.

Thanks. I found that but could not see any place for downloading. But I found the NetPBM pnmtorle and it works. But the image is binary and not text. So I cannot read the file to see the run lengths.

This was just trying to help someone else and is not that important to me per se.
