I suspect this won't work at all on windows due to the way the transform is implemented there, but someone should probably check. > I chose 'h' as the action key because 'm' and 'f' were reserved, and > 'h' is easy to memorize ("horizontal"). 'r' for reverse, maybe? Is it possible to do the mirroring before the rotation instead of as part of it? I feel like it would make the code a little clearer, although I suspect you're doing it in the rotation to reduce the number of calculations? Would it be possible to have both horizontal and vertical mirroring? -- Alan Third From debbugs-submit-bounces@debbugs.gnu.org Tue Dec 28 13:09:54 2021 Received: (at 47095) by debbugs.gnu.org; 28 Dec 2021 18:09:54 +0000 Received: from localhost ([127.0.0.1]:47368 helo=debbugs.gnu.org) by debbugs.gnu.org with esmtp (Exim 4.84_2) (envelope-from ) id 1n2Gv4-0006sH-2d for submit@debbugs.gnu.org;

(Sorry, I'm not following this thread. Please ignore if my comment is OT or otherwise irrelevant.) But if this is about mirroring in the sense of flipping an image horizontally around its vertical midline, then `h' makes sense (and it is used in some image-display programs). Similarly, if we have vertical mirroring then it makes sense to use `v' for that.

Would it be possible to have both horizontal > and vertical mirroring? As said elsewhere, "r" is reserved for rotation. :) I added an elisp function to do a vertical flip. Also I renamed the procedure flipping because that's what GIMP calls it. Attached is a revised patch to replace the previous one. As for the C code, I agree it adds some complexity to the transform function, but this is probably the fastest way to achieve it. Flipping before rotation would lead to strange results when the image has been rotated 90/270 degrees. Then the flip commands seem reversed – horizontal flip actually flips vertically and vice versa. This is because the transform function always rotates the initial image, which is what would be flipped. Hopefully someone can test this patch on Windows. --=_265cb715d031de7c994bf9af20596f49 Content-Transfer-Encoding: base64 Content-Type: text/x-diff;

That's actually what I'd expect to happen, tbh. :) There's a bit of a problem with Emacs image manipulation, IMO, in that the transform order is baked in, so we end up with strange situations like when you set max-width, then rotate 90 degrees so now max-width affects the height of the image instead of the width. So whatever, I don't feel very strongly about it. One more thing: do you feel up to adding a note in the manual about this new property? It should go in doc/lispref/display.texi. Look for rotation. > Hopefully someone can test this patch on Windows. Indeed.
