hello again,
I have attached to this post a zip file with
11.odt original file before I include it in calibre
11 - unknow.odt file odt included in calibre
11 - unknow.epub conversion by calibre from odt to epub
job_details is the file with the .... job details
metadata.opf is the file opf found in the calibre created folder
in my 2 odt, there is only one version of each images, in the epub, there seems to be 1 version in png format and one in svg format
for info (this is not a comparison as I am very grateful for your work), I have done the conversion with the LO plugin writer2epub and did not have this issue
reup
