I'm getting there slowly, by cross-checking Affinity specific problems, plus following YouTube tutorials. I've found the way to resize by pressing a lock symbol, which prevents auto-resizing. That's one down. The next was to rasterize, and then place an empty text box on the left side of my future book cover. This allowed me to see the 'Inlooker Back Cover' that John Rostron could see but I couldn't. Then I deleted it by putting it in the dustbin., before adding the required text. John's layman's description of the CROP command as being the' harvesting' of what is selected was not helpful. Coming from Publisher, which has a fatal flaw in it, the descriptions used are understandable, like cropping = cutting out unwanted areas of an image. I still cannot see how to use the CROP tool. Now I have published my book cover to Amazon, and will alter it later, when I get to grips with text colors and providing a darker background to the text, in a block. Alpha is an intriguing product, but it is riddled with idiosyncrasies. My overall impression is that I've chosen the wrong product, but I didn't know about Designer, etc. It is overkill. Also, some of the tutorials are naive, like showing the main Affinity work area recolored black, which means that I cannot see what is being done. The clue comes when the designer changed the minute text to white, but didn't say how. I may have to stick with MS Publisher for the straightforward tasks of book assembly, then transfer the lot across for PDF export. The presentation of tools and other components is excessively dark and small. It's going to test my eyesight to the extreme on a Windows PC.
