ianrb Posted March 12 Posted March 12 HOW TO ROTATING A SELECTION HORIZONTALLY Make the selection as normal Save selection as a File Open new black document the EXACT size as the original photo Add a new white layer ''Load selection from file'' to top layer Add a mask Delete the selection Merge white onto black Rotate the photo. I used the new “select subject” to make a new section Save selection as a file Return to, and rotate the original photo ''Load selection from file'' All done and easier than for 'me' to type out and you to read/understand. I'm sure there is; or there needs to be an easier way. Now that was a real feel good moment for many reason. All Affinity educators are free to use. Yurembo 1 Quote
NotMyFault Posted March 12 Posted March 12 This is very confusing to me. Can you please explain: What is meant by rotating a selection horizontally? Rotation normally means circling around a fixed point, the center of rotation, and is unrelated to horizontal or vertical axis. horizontal or vertical axis are used if you flip something what object do you actually modify (rotate) the selection (what is visible as marching ants or quick mask) the content of a specific pixel layer within a document (using the selection made before) the whole document I have a vague interpretation that you may intend to select some area on a layer within a document, and rotate it. But it is still a bit unclear to me what you do with the background, and why you use such complicated workflow. It seems you try to transfer the selection between two open documents. Using a mask layer and copy/paste would be faster (assuming square document size).

NotMyFault Posted March 12 Posted March 12 Looking at your images it seems you just flipped the canvas (or whole document), as described in help: https://affinity.help/photo2/en-US.lproj/pages/SizeTransform/canvasRotateFlip.html but the blue outline has changed its color Paul Mudditt 1 Quote Mac mini M1 A2348 | MBP M3 Windows 11 - AMD Ryzen 9 5900x - 32 GB RAM - Nvidia GTX 1080 LG34WK950U-W, calibrated to DCI-P3 with LG Calibration Studio / Spider 5 | Dell 27“ 4K iPad Air Gen 5 (2022) A2589 Special interest into procedural texture filter, edit alpha channel, RGB/16 and RGB/32 color formats, stacking, finding root causes for misbehaving files, finding creative solutions for unsolvable tasks, finding bugs in Apps.

To flip or rotate a selection together with document in fewer steps: while the the selection is active, click on the mask button (create mask layer from selection) Deactivate selection (this is optional, to avoid distractions) flip or rotate document/canvas use selection-> create selection from layer delete or deactivate mask layer (optional, if no longer needed) Quote Mac mini M1 A2348 | MBP M3 Windows 11 - AMD Ryzen 9 5900x - 32 GB RAM - Nvidia GTX 1080 LG34WK950U-W, calibrated to DCI-P3 with LG Calibration Studio / Spider 5 | Dell 27“ 4K iPad Air Gen 5 (2022) A2589 Special interest into procedural texture filter, edit alpha channel, RGB/16 and RGB/32 color formats, stacking, finding root causes for misbehaving files, finding creative solutions for unsolvable tasks, finding bugs in Apps.

If by chance you have a fill color active with reduced opacity, the results will be wrong.

NotMyFault Posted March 12 Posted March 12 This is the reason i recommend basically the same workflow like you, only with a mask layer which has no dependencies to color or other settings.
