From 127abbea770e1fff660b0ffd10ab58bcb46bf0af Mon Sep 17 00:00:00 2001 From: mamg22 <45301823+mamg22@users.noreply.github.com> Date: Tue, 30 Nov 2021 19:52:09 -0400 Subject: fix crash when zooming out on small images (#178) When rendering images, destination image width and height may become zero due to float-to-int conversion after zoom calculation, later crashing when creating an image using those dimensions. This sets a minimum of 1 to both variables.
