Tiff files conversion to pdf failing

[vlakka]

Hi, We are using libreoffice as a utility to convert files to pdf. We are seeing errors as below when converting tiff, docx and few jpeg files into pdf.
Error when opening the mentioned files using LibreOffice desktop version:
Image filter not found → Click OK (below error)
General Error. General input/output error

Command line execution also errors out with message
./soffice --headless --convert-to “pdf:writer_pdf_Export” test.tif
Error: source file could not be loaded.

Please suggest how I can go about resolving this.

Please report the behavior as a bug in Bugzilla .

Give good details about your operating system, LibreOffice version. Include a sample file so that the developers can reproduce it, as well as a good description of how to achieve reproducibility of the error.

Thank you for responding.

Due to the tiff files containing some confidential information, I am unable to upload them to Bugzilla.

To help me debug this further, does Libre office look for any particular metadata when opening a tiff file? Could you please list them out.

This error does not happen with all the tiff files. I am looking to check if the file that doesn’t work is missing required metadata.

If you are using LO 7.0.0.3 there was bug tdf#138818. Most other TIF bugs seem to be rendering issues.

Maybe worth seeing if there is commonality in the TIF files that fail. What sort of file compression is used on failed conversions, none, LZW, Zip, etc. Do they all contain transparency. What bit depth, or black and white or greyscale.

If I insert a 16bit floating point TIFF image (by GIMP) into Writer I get a dialogue box to insert a section instead of an image. This would certainly cause a hiccup in your conversion. Same with 32 bit image floating point or integer.
