I have some image files to edit. Extensions are wmf. How can I edit them?

Question

I cant use the other image forms because these are part of a latex project. I need to do some simple editing such as adding arrows in the pictures. Windows-Paint does not support the wmf files. Also photofilter does not support them. Why dont people use jpeg, gif, bmp files and so on? Help needed!

Answer 1

Have a look here - lists a couple of options for you; conversions to either vector or raster (pixel-based) formats ....you should be able to take it from there. This is always the risk when using software or file formats that are so rarely supported
