I’m building a webapp, and I need the ability for users to view Word/Excel/PPT files in the browser (these files are stored server-side). So i decided it will be better to convert these files into thumbnail images
20 slides powerpoint to 20 images
What is the best way to do this or any other way around to solve the issue
PDFCreator can save to several formats, including PDF, tiff, png, and jpeg. It exposes a COM API and provides samples for using it.
Instead of exposing the COM objects, it might be simpler to write a simple PowerShell or cmd.exe script to print the first page of the document to the PDF creator printer. You can use the open source utility classExec to do this. This page is a good reference for DDE in general.
