What type of WPF image should be used to perform several conversions

I need to perform several operations with the image, for example, I need to resize the image, maybe place it to maintain the aspect ratio (and draw the background color) and conditionally print the watermark.

I am currently using BitmapFrameas the type that I pass between the methods used.

Can anyone recommend a different type that I should use to perform incremental image updates?

I could create a composition from different images, although I'm not sure which types I should use for this?
