On the Android S7 tablet, I do have the Mirror tool in my toolbar but it only mirrors on the vertical axis. Then I tried looking in the menu items and did not find a Horizontal mirror tool at all. When I tried customizing the toolbar, I did see a Horizontal mirror icon and tried that but it did not do anything, it just didn’t work.
I need to be able to flip my work (and the reference photos) upside down to check my accuracy. Simply mirroring vertically doesn’t always help. Horizontal mirroring adds an extra viewpoint for checking alignment problems. And having to use rotation only is annoying.
The Image > Mirror Image Vertically might be better choice if there’s many layers
But these solutions are slow and “destructive” (destructive in the way the original layer content is modified)
The mirror view is really useful.
I never felt the necessity to get a vertical mirror view as the current horizontal one match my need, but everyone have different need
@CrazyCatBird for me the current mirror view is an “horizontal mirror view” and what you want is a “vertical mirror view” (if we keep the same wording/signification of Image > Mirror Image Vertically tool
So flipping something upside-down (in printing that’s work-and-tumble) is vertical mirroring and flipping it right to left (in printing, it’s work-and-turn) is horizontal? That confuses me.
OTOH, it doesn’t flip the reference images along with the canvas the way the mirror view button does. I hope I can find a way to have the entire canvas flipped vertically then.
I think it’s partly because Krita has at least three different instances where it uses ‘mirror’:
The mirror tool is for drawing with replication either side of a vertical or horizontal divide.
Then there is mirroring the canvas which could be called ‘flipping’ instead. There are two ways to do this - one is to mirror the view, which only affects what you see while the file retains it’s orientation (the overview window always shows the actual file orientation). The second is to mirror the image which will affect the orientation of the saved file (again will show in the overview).
As for vertical vs horizontal - That can get confusing as the mirror tool uses a vertical dividing line to mirror horizontally, or horizontal line for a vertical mirror!
The flipping-type function is horizontal = side to side, vertical = top to bottom.
I’m not sure I’ve added anything that hasn’t already been said, but maybe it helps to have it put in different ways?!
I think also there is some confusion because that button you’ve placed in your toolbar is in the same location the mirror tool usually resides. In my layout, that mirror view button sits below the overview window.
To be honest I think everything mentioned could do with revising as it’s pretty confusing as things stand - I mean to improve labelling and address any missing functionality.
