[Bug]: PDFs that are indigestible to OCRmyPDF cause error messages #1470

Open noseshimself opened 1 month ago

noseshimself commented 1 month ago

The Problem

If a PDF file has an "unusual color map" (whatever that is) and needs additional parameters for recognition (message: "Vibration-Sensor_Manuals_EU.pdf: Error occurred while consuming document Vibration-Sensor_Manuals_EU.pdf: ColorConversionNeededError: The input PDF has an unusual color space. Use --color-conversion-strategy to convert to a common color space such as RGB, or use --output-type pdf to skip PDF/A conversion and retain the original color space.") tools like PDF-to-PDF/A are (expectably) throwing errors, too.

An example file will be attached. I hope. Vibration-Sensor_Manuals_EU.pdf

Additional Information

Yes, the color space of this file is completely messed up. I wonder if it is worth checking this before passing files to external tools and using different parameters in case (see the OCRmyPDF message).

I cant reproduce this on latest Stirling-PDF version using your exmaple file, i wonder if this was patched in later OCRMyPDF versions that docker has pulled

Frooodle commented 1 month ago

Are you able to update and see if you can reproduce? I also tried on our public instance and also saw no issue https://stirlingpdf.io/ocr-pdf

I'm now getting the expected error message:

See the last few words: ColorConversionNeededError: The input PDF has an unusual color space. Use --color-conversion-strategy to convert to a common color space such as RGB, or use --output-type pdf to skip PDF/A conversion and retain the original color space.

I guess additional parameters are necessary in this case

still very confused that i dont see any error using your example file in https://stirlingpdf.io/ocr-pdf Are you not using docker?
