I am a relatively new Affinity Photo user, and I have been having some exporting issues with the program. For clarity, I am an Apple user using an iMac (Retina 4K, 21.5-inch, 2017) with operating system Mojave 10.14.1. I have the exacting dimensions of a photo that I modified, edited, and completed in Affinity Photo as a saved .afphoto document, but upon exporting the image, either as a .JPEG, .PNG, or TIFF, the resulted image I receive is bigger than the dimensions I had saved it for. It appears stretched and pixelated as if I had manually blown-up/zoomed the image in Affinity Photo without preserving any of the pixels. It also appears more saturated than the screenshot I have. Attached are two examples of the photo, and two reference screenshots of the settings I have on as well as the dimensions. One is a screenshot of the same photo that is sized correctly in accordance to the dimensions I had, originally, saved and exported it for, and the listed file detail dimensions match the size I am viewing. The second is an exported version of the photo that under file details is listed as the dimensions I saved it for, but upon selecting and opening the file it opens as a largely blown-up image of the photo despite being listed under details as being the exacting dimensions I would expect it to be. It's as if the photo automatically forces my computer to blow-it-up to a larger, zoomed-in size that stretches and pixelates the image. I'm sure there's an easy explanation for why this is occurring, but I have been unable to solve it on my own. May I have some assistance?
