Each example file in help contains the image preview (stored in the "Thumbnails" zip directory of the ODF file). I ran the below command in help directory (with only fr translation installed) : find . -type f -not -iname '*.htm*' -not -iname '*.js' -not -iname '*.css' -not -iname '*.svg' -not -iname '*.png' -not -iname '*.xsl' I got the below results : ./media/navigation/favicon.ico ./media/icon-themes/color_scheme/standard ./media/icon-themes/color_scheme/dark ./media/icon-themes/README.txt ./media/icon-themes/COPYING-ICONS ./media/files/scalc/pivot.ods ./media/files/scalc/conditionalformatting.ods ./media/files/scalc/functions_ifs.ods ./media/files/scalc/function_fourier.ods ./media/files/scalc/imtrigon.ods ./media/files/scalc/trigon.ods ./media/files/scalc/fr/pivot.ods ./media/files/scalc/fr/conditionalformatting.ods ./media/files/scalc/fr/functions_ifs.ods ./media/files/scalc/fr/function_fourier.ods ./media/files/scalc/fr/imtrigon.ods ./media/files/scalc/fr/trigon.ods The "ods" files use 262 ko. Removing all image previews from them saves 122 ko. When we remove the image previews in each of 119 translations, we could save up to 7344 ko of installed size. This could reduce the size of the install archives to be installed on the host.
Thanks Jérôme. Cloph, Olivier, what do you think? It's a "why not" for me.
I propose to fix this bug as follows. First, I edit the “*.ods” files in 'helpcontent2/source/media/files' with the LibreOffice Calc stable version 7.4.7.2. I uncheck the “save preview image with this document” property (“file” menu, “properties...”). Finally, I have each file without its preview thumbnail. Next I create an unit test in order to check regression in 'helpcontent2/source' directory. Do you agree ?
