[gdal-dev] how to batch rgb2pct

[Matt Wilkie]

Hi Micheal,

rgb2pct is a batch file, so when used inside another batch it must be 
"called" in order for control to return to the initiator:

   call rgb2pct v:\historic_topos\rects\w\arnold-pond-w.tif 
v:\historic_topos\8bits\w\arnold-pond-w.tif
   call rgb2pct v:\historic_topos\rects\w\attean-w.tif 
v:\historic_topos\8bits\w\attean-w.tif
   call rgb2pct v:\historic_topos\rects\w\baker-lake-w.tif 
v:\historic_topos\8bits\w\baker-lake-w.tif
 
If I may extend your script a little:

   @echo off
   for %%f in (arnold-pond-w.tif, attean-w.tif, baker-lake-w.tif) do (
      call rgb2pct v:\historic_topos\rects\w\%%f 
v:\historic_topos\8bits\w\%%f
       )

or interactively from the command line:

  pushd v:\historic_topos\rects\w\
  for %f in (*.tif) do rgb2pct %f ..\..\8bits\w\%f
  popd
