Errors with .emf and .tif pictures

We developed a code to storage some data. We got two errors when working with .emf and .tif files. In the first case, the picture doesn't appear. In the second case, the picture appears but becomes almost fully red. With others formats like .png or .jpeg it doesn't happen. I don't use any toolbox now.

Anyone knows why it happens and how should a fix it?

Thank you very much for any reply!
