pg2286/ppt-to-image repository overview

Dockerfile supports conversion of powerpoint to image and word document conversion to pdf using unoconv package and imagemagic convert function.

Supporting office document conversion (powerpoint/excel/word) now is easy with opening a shell/system command from language of preference, for e.g. in this one I am installing php and fpm along with nginx to install the webserver.

You can run the docker container and then login into to convert a file docker run -it --memory 3g -v /<MAP_HOST_DIR>:/var/www pg2286/ppt-to-image:v2 /bin/bash

Now change directory to /var/www and assuming 477.pptx file is present run the below command . This command will convert a given pptx for e.g. 477.pptx into a pdf file with the same name 477.pdf unoconv --export Quality=100 -f pdf 477.pptx

once converted we can run the imagemagic convert command to convert the compressed jpg

convert -density 260 -gaussian-blur 0.05 -resize 50% -trim large_ppt.pdf -quality 85% density_260_large/large_ppt_%03d.jpg

#Word document to pdf #unoconv --export Quality=100 -f pdf doc/PranavGarg.docx
