Admittedly I'm a brand new Affinity Designer user. I purchased Affinity Designer for work on one specific image I purchased from Shutterstock. I'm very used to Sketch for UI/UX Design. Basically, I'm trying to do the following very basic steps with Affinity Designer. The image I purchased is a .EPS, and loads fine in Affinity Designer. The download is a rectangle with a lot of white space at the top and bottom, I need to remove the white space, and just focus on the image. The download is 452x452. The goal is to create a @2X and @3X images for Xcode Assets. I created an artboard around the image, and the artboard is 378x226, not quite the size it needs to be. I need to scale it so it's close to the 454x267 size I need and then export to the scaled sizes for Xcode Assets, which would be 2x (908 x 534) and 3x. (1362 x 801) all the while maintaining the pixel perfect image. Thanks in advance.
