Questions and postings pertaining to the usage of ImageMagick regardless of the interface. This includes the command-line utilities, as well as the C and C++ APIs. Usage questions are like "How do I use ImageMagick to create drop shadows?".
I got the following analysis of my large TIFF conversion problem and advice:
Your image is a BigTIFF and it requires that ImageMagick be built with the BigTIFF version of the TIFF library. We confirmed your image can be read with ImageMagick built with libtiff-4.0 Beta.
I have been fishing around, but I am unable to get any traction on locating such a build for Windows. I thought there was a dynamic build, and that I would just need to find the DLL for BigTiff, but all I can find is a .lib. Can anyone help me?
Perhaps Windows is not that different. Has anyone installed the libtiff from aperio and gotten it to work on any platform? I suspect there were lessons learned that might apply to my efforts.
You may be better off using libtiff-4.0.0 Beta from remotesensing.org. You should be able to add / replace the source and header files from libtiff-4.0.0 in the WIndows ImageMagick-6.7.2/tiff source folder and build.
