TurboPrint & PrintFab

I am trying to quickly position and, ideally, crop images that I drop into Printfab Composer. The type-in length/width values is perfect for quickly scaling. The type-in position values are from the edge of the image, not the center of the image. This makes centering the image on the paper a pain. Can this be set to measured from center so that, for example, an X value of 6 would be centered on 12" wide paper?

Second, I know that the white handles allow you to crop the image with your mouse. Is there a more precise type-in version of setting an image's cropped width?

Hello and please excuse the late answer. There are two buttons at the top of the composer window for horizontal and vertical centering. Numerical input of crop values is currently not possible but we can add this to the "wish list" for future enhancements.
