So eventually the image will become corrupted? This image gets
resized many times, from big to small and back again, in little
I tried creating a button and using the image as an icon, and
resizing the button instead of the image, but as the button got
smaller, instead of the image getting smaller too, it just got
cropped off at the edges.
The goal is:
There is an image
If the user does something the image gets a little bit smaller
This will happen many times, until the image is very small
On relaunching the program, the image starts out at the original
(big) size again
Will this eventually corrupt the original image that is embedded, so
that it no longer looks the same as when I embedded it?
