Limitations of the image cropping feature depending on the current layout
When the current layout is the Custom layout printing, you can select a clipping area of any size
and any height/width ratio.
However, in case the current layout is the Tiled photo printing, Fixed photo size printing, or
Canon perforated paper printing, cropping is restricted to the vertical clipping or horizontal
clipping. This is because the height/width ratio is fixed in these three layout modes.
