I have created a portability layer for plugins, so most plugins that use ImageMagick should still work. However, the one part that could not be ported is writing text on images.

For that, the plugin would need to switch over to using QPainter (which is a better approach anyway and is what the generate covers code in calibre itself uses). Feel free to ask me if you have questions on how to port any specific functionality.
