Crop the part of the image - how?

Hello
Is there any posibility to show only the part of the loaded image - not the whole one? It would be useful for puzzles and similar stuff...

how about using a mask?

this is in the wrong forum category by the way. this is about the Lua language, not Corona features

Hi tetu
Can you please give me a help how it can be done in Lua?

Thank you!!!
