Office Importer Application - Change resolution of imported Powerpoint

Hi,

how to change Change resolution (quality) of imported Powerpoint presentations? I found an info on the extension site (https://extensions.xwiki.org/xwiki/bin/view/Extension/Office%20Macro#HConfiguration) - but i dont know how to change these variables or even where these files are…!!!

Blockquote The office macro uses the office server to convert presentation slides into images. By default these images are not very large. If you want to configure the image dimensions and other stuff you’ll have to copy document-formats.js from the jodconverter jar to WEB-INF/classes and edit it. For instance, if you want the slide images to have 1024px width you have to change this line:
“PRESENTATION”: {“FilterName”: “impress_html_Export”, “FilterData”: {“Quality”: 90, “Width”: 1024}},

Sorry if i ask something completly dull - i am new to xwiki and try out now how it could replace our confluence server…

thanks!
