| Post subject: | Image subclassing problem |
Hello, in my application I have subclassed the MigraDoc Image class. If I add an instance of the class to a section everything works fine. However, if I add it to a paragraph, the image does not display. This can be seen using the following class Code: class ImageSub: Image{ public ImageSub(string path) : base(path) {} } The MDDDL files generated by using the above subclass and by using the Image class are identical, so this seems like a bug in the rendering code. Is there any way to work around this limitation? I am using the GDI+ version of MigraDoc. |

Hi! What's the purpose of your subclass? The MDDDL files are identical - so when the MDDDL is read, the normal Image class will be used and not your subclass. |

I'm using a stack based approach to build PDFs from HTML, so I added interfaces and some helper methods to the subclasses to reduce the amount of type testing I have to do in my code. I did manage to work around this by using an extension method, but the behavior of not displaying the image only when it's inside a paragraph is still odd. |
