I would like to batch convert all images in a subdirectory to create pyramid tifs. My windows dos .bat file is:

@ECHO OFF
convert.exe c:\image\jpg\200311032.jpg -define tiff:tile-geometry=256x256 -compress jpeg ptif:c:\image\ptif\200311032.tif
PAUSE

I want to do something like

@ECHO OFF
convert.exe c:\image\jpg\*.jpg -define tiff:tile-geometry=256x256 -compress jpeg ptif:c:\image\ptif\*.tif
PAUSE

But it errors on recreating the file name for *.tif.

The wildcards * and ? expand to a list of files, but the output files don't yet exist and so this doesn't make sense. Even if they did exist, ImageMagick couldn't match the inputs to the outputs. Fortunately there is a solution. See:
http://www.imagemagick.org/Usage/files/#save_escapes

Here is the answer:

::Turn of displaying the code on the screen

@echo off

:: Read all the jpg images from the directory, convert them to 256x256 tiles, compress jpeg and create the pyramid tif in another directory

for %%f in (c:\image\jpg\*.jpg) do ( convert "%%f" -define tiff:tile-geometry=256x256 -compress jpeg ptif:c:\image\ptif\%%~nf.tif )

PAUSE

Found the basis for this on http://www.rubblewebs.co.uk/imagemagick/batch.php

I'm looking at pyramid tiffs because of: http://iipimage.sourceforge.net/

A great solution!
