Description johnks 2021-08-26 15:07:27 UTC

Description:
i have attached a pdf i downloaded from a url to pdf website. the page is of libreoffice wikipedia. Also attached is output of my draw if i exported the pdf. 

there are various formatting issues. 
1. on the first page, bottom right, there is a service hyperlinked image. that is gone in draw output.
2.on page 3, bottom right text box "libreoffice viewer on android" has bottom part one pixel line cut off in original. in draw output, a lot more is on 4th page.
3.on page 6, the wide image is within box in the original and in draw output, the same goes outside on left side.

4. more troubling is the fact that all hyperlinks are gone in the draw output. This should not silently fail as the pdf is expected to be the same as input and if input had hyperlinks, output should do so.

Steps to Reproduce:
1. open original file in draw. click on export directly to pdf
2. compare input to output file


Actual Results:
draw output file is different from input file

Expected Results:
output should be same as input


Reproducible: Always

new file to import into draw

check the rendering in draw as compared to any pdf reader. the result in draw is mangled text and all rendering wonky. also attacking output of "export directly to pdf" as well

Confirmed

LibreOffice makes no claim that Round trip-- PDF import filter, PDF export filter --will produce even remotely similar documents.

LibreOffice is not a PDF editor (open the PDF and write changes directly into it). 

Rather, we read in a PDF stream, we write out a PDF stream within limitations of the filters and document formats available.

There are specific issues with the filters, and those should be addressed with specific BZ issues for each (both the import filter, and the export).

*This* issue is not-actionable.

IMHO => INVALID
