I recently changed my code to write TIFF files in strips of 256kB rather than by scanline.

The code writes a 32 bit rational TIFF file. This file is quite large (100s of MB) so I'll only make it available via a file sharing site.

When opened in Photoshop CS6 through to CC 2020 it displays fine and I can convert to 16bit and save it and PS will reload it OK, but all other applications choke on the 16 bit file.

I can open the 32 bit file OK in GIMP and IrfanView, so I don't think that I've messed up - I think it's a PS bug.

Have you seen this before?

Thanks
David
