How to scale images automatically?

[Xtasy26]

I making a program which is essentially an etch a sketch type program where I would open a jpeg file and using the mouse I would let's say draw a circle over the image and in the new image a circle would appear over the image. The new image would be another box. My question is how do I make the image I draw to fit inside the box; so that no matter how large the image image I draw it will automatically scale and still fit the box. Thanks.

Hi,

am I correct that you want to scale your JPEG, so it would fit inside the box?  if so, this may be the answer :
