I have the following code in my program that uses IEvolution:
bool loaded = HiComponents.IEvolution.MiscPluginsImageMagick.RegisterPlugin(); if (!loaded) { MessageBox.Show("The ImageMagick plugin has not been registered. PDFs will not be viewable on this screen"); }
Firstly, ensure you have installed the version of ImageMagick that matches the bitness of your application (not the O/S). I.e. if you are creating a 32bit app you need the 32bit ImageMagick.
Secondly, for PDF support you also need GhostScript to be installed.
