Question

Transform Skew by mouse vs by typing exact value

Hello,
I attached a video with the details.

I've done a skew on 2 selected objects by mouse dragging, but I want to get the same result by typing an exact value (number) rather than using the mouse drag. Because it's hard to drag the mouse to an exact whole number, so I want to make it by typing a value as a number, not dragging. The problem is when I type a number, it does the skew but only to one side (I want to bring 2 corners closer to each other). But with typing it only skew the whole thing to only one side, which is not what I want.

Best,

Adam

    Come to think of it … 

    Transforming multiple Layers via Script works out easier by grouping them and evaluating the »boundsNoEffects«.

    FWIIW I almost never use the Free Transform settings.  I Ctrl drag a corner handle to distort

    Ctrl drag a middle handle to skew

    The only time I use the X: and Y: field values is for the centre handle, like when using Step & Repeat

    Unfortunately, the outside handles wont snap to guides or the grid.

      By virtue of the keyboard shortcut you are using you are not skewing.

      That you haven’t been using the term »skew« correctly? 

       

      If you want to be able to give numerical input for perspectival transformation in Photoshop you would need to use a Script as far as I can tell. 

      Which seems perfectly possible (for a first transformation at least, if the object is a Smart Object that has already been transformed the issue gets »murky«), but which kind of input makes the most sense in your use-case? 

      An angle or a distance for the two corners or the percentage of the width in relation to the original width or …? 

       

      Please provide sample files for original and intended result.

      The difference in your result seems to be the keyboard shortcuts you are adding. What exactly is Control-Alt-Shift doing to the image? Is the Alt key making both sides move and the Shift Key constraining it? If so, then this is what we need to duplicate when typing in a number.

        It’s a combination of the common shortcuts which work across transformation types, when dragging a handle of the transform bounding box.

        Option/Alt = Transform from center

        Shift = Transform proportionally

        Command = Warp only one corner of the bounding box

         

        Command+Option = Skew

        Command+Option+Shift = These modifier keys seem to achieve the same thing as Edit > Transform > Perspective.

         

        That last one seems to be the problem here:

        The thread title talks about skewing, but the video does not show skewing. The result shown in the video is the same as Edit > Transform > Perspective, not Edit > Transform > Skew. But the options bar is not showing perspective values, it shows skew values. So changing a skew value will not achieve a perspective result.

         

        It doesn’t look like the options bar offers a perspective setting. The options bar doesn’t even offer a perspective value after choosing Edit > Transform > Perspective!

         

        So there may not be a way to apply perspective using the options bar, but I hope I’m wrong.

          "the options bar is not showing perspective values, it shows skew values"
          Yeah, you're probably right. But I can't modify the question's title from skew to perspective. Since Photoshop showed me skewing options at the bar, I couldn't decide if it's the skew or persp menu actually...

          Yeah, that's not your fault, when the Perspective command is chosen there should be a Perspective field up there. And it would also be nice to have a Perspective field in the options bar when the Free Transform command was chosen. This area could use some refinement and clarification for sure.

            You are right. I also tried with perspective wich does not require any shortcut and the problem remains the same. Changing the angle value only affect one of the rectangles…

            Hope somebody will find a trick. But this meust be reported to the Photoshop team not as a bug but a deficient functionality that they could consider to enhance…
