The standard download for windows does not support BigTiff. Has anyone been able to locate or build gm with a library supporting BigTiff images?
Does anyone know of another product, commercial or non-commercial, which will handle such a file, including page extraction and cropping?
I need to be able to take a multipage tif file and work with a selected page within the file - extracting (aka cropping) 4 normal tif images from the single BigTiff.
I am planning that the next GraphicsMagick release will include libtiff4 and support BigTIFF. In the mean time, see if you can find a libtiff4 built for Windows because libtiff4's 'tiffcrop' program will likely do what you need.
