how to change transparency options on a bunch of ecw files

I have a bunch of images in ECW format that I have reset the transparency definition. I would like to export each one as a new ECW file. I can not find the function that allows a 1-for-1 export. I can tile, or manually set to each overlay, but those two options are not ideal.

    You can use File->Batch Convert/Reproject to do a one-for-one conversion of files.

    Thanks,

    Thanks for the response last year... it works very well.
    I have a new and related question:
    How might I include the "Fuzzy" definition of the transparent color in a Batch operation like the setting available in the Raster Options dialog?

    There isn't currently a way to control the transparent color "fuzziness" during batch conversion, but you can do the export using a script where you provide the transparent color and fuzziness distance using the IMPORT command http://www.bluemarblegeo.com/knowledgebase/global-mapper/ScriptReference.html#cmd_import for TRANSPARENT_COLOR and TRANSPARENT_COLOR_DIST. You could loop over the files to convert using the DIR_LOOP_START and DIR_LOOP_END commands.

    Let me know if I can be of further assistance.

    Thanks,
