Re: [Tiff] EXIF tag writing fails starting with libtiff 4.5.1?

Hi Bob, would it be possible to share the submitted code, how the TIFF IFD and the EXIF IFD are handled. Are the error reported below from GraphicsMagick? How to reproduce this error? Then I could have a look. Handling such "Customer IFDs" was always a tricky thing, because the TIFF IFD has to

Hi Ganesh With the testfile LibTIFFCrsh1.cpp I get the error message: "TIFFWriteRawStrip: Must set "ImageWidth" before writing data." That is, you can't just create a default TIFF directory (out = TIFFOpen(sInputSinglePage.c_str(), "w");) and then write image data to that directory without

Dear David, there is an initial merge request (see https://gitlab.com/libtiff/libtiff/-/merge_requests/337). However, there are some issues at this stage. I was preparing an improvement at the time. I could update it and then upload it to my repository. From there you could get it and try it.

Re: [Tiff] Remove TIFFCROP from LibTiff

I would prefer Even's proposed solution to move problematic tools to archive/tools/. The executables in use are still usable. If individual maintenance is absolutely necessary, the source code is still available (not only in the repository but also in the distribution). Su

Re: [Tiff] libtiff v4.5.0 release candidate available

Hi, I had a quick look at it. Within libitff, the number of directories / directory number is stored in an uint16_t and the number 65535 was treated as a magic number for a "non-existing directory"! Thus, libtiff can only handle 65534 directories. However, many libtiff functions do not
