Rescale image without filter [message #59438] Tue, 27 December 2022 10:58

Hello everyone,
I'm new user of U++, coming from C, and currently learning C++. So maybe my question will be very simple, but I didn't manage to do what I want.
I'm using the Apps example ImageViewer. It uses an ImageCtrl to show images. I wanted to add a "zoom-in" / "zoom-out" feature.
So I did it with the Copy function, after defining a rectangle corresponding to the area I'd like to zoom. Then I used the Rescale function.
All is ok, but when I zoom in, the rescale function seems to add "blur" on sharp edges. Is there a way to rescale an image without such filter ?

Thank you,

Regards,

Gerald
