Okay, good news - I managed to recover nearly complete images from both of the 'broken' TIFF files you shared. The file was truncated, in fact in both cases it seems to be truncated after about 90-95% of the image data. I don't understand how this would happen. Did you have the option to save FITS headers in the TIFF description turned on? That re-opens the TIFF and updates the headers, so I suppose that could go wrong maybe.
Anyway, I have made a tool that will recover the image data for you
Download : https://downloads.sharpcap.co.uk/tools/TiffRescue.zip
Source Code : https://github.com/rwg0/tiffrescue
To use it, unzip and run it from a command prompt like this
Code: Select all
TiffRescue.exe WIDTHxHEIGHT broken_file.tif
Code: Select all
TiffRescue.exe 4944x3284 path\to\file\capture_00027.tif
You will notice that the fixed files have a black stripe at the bottom - this is the part for which the image data is broken/missing.
Hope this helps,
Robin
