    Move/Nudge 1/2 a pixel?

    Kar209 Level 1

      Hey there                                                                                                               Level: Newbie   OS: Windows 7 64bit     Ps: Cs6

       

       

      Is there a way I can move an object 1/2 pixel? Is there a modify key that I can use along with the arrow keys or something like that?

       

      Thanx for your time!!

          A good question that is!

           

          Earlier versions of Photoshop used to do this depending on zoom level. If you're zoomed in at 100% on canvas, one nudge will be 1pixel relative to your current object position. 200% will be 0.5 pixel and so on all the way till 3200% which nudges 0.03125px.

           

          In Photoshop CS6, there is a handy little option that is (usually unnoticed) present in General Preferences.

           

          Go to Photoshop Preferences > General > Snap Vector Tools and Transforms to Pixel Grid - uncheck this option as shown in screenshot below:

          Once unchecked, Photoshop will behave like it did in earlier versions. Zoom level controls the nudge. 100% zoom is 1pixel nudge and 200% is 0.5pixel nudge.

           

          Note that this behavior will work only with 'Free Transform' (Cmd + T) or (Ctrl + T) on your object. A normal nudge with Move tool (V) will not nudge 0.5pixel.

           

          Trust this helps.

            Are you sure the OP is talking about Paths/Pathpoints? (It would not make a lot of sense otherwise, but still …)

              Paths as well as raster elements will nudge 0.5pixel if 'Snap Vector Tools..' is unchecked under General Preferences.

                Since when would pixel content nudge (I mean a plain Move Tool nudge, not nudging while doing Free Transform) less than one pixel in Photoshop?

                  Valid. My bad I didn't mention that in my previous response. Only a Free Transform will let you nudge less than 1px. I'm appending my previous post with this right away.

                    For Vector shapes, if you add one to their size, they will grow by half a pixel on either way (you might need to uncheck the snap, too)

                     

                    For pixel layers, another way is to double the size of your documents (from 300 to 600PPI), nudge, then downsample. You will get dithering, though.

                      My goodness. lol

                       

                      I had no idea I was asking such an involved question.

                       

                      I forget that Ps is mostly raster ... ( um, right ?? )

                       

                      I thought of Inkscape where if I recall correctly all I need to do is to hold the Alt key and use the arrow keys in order to more percisely place an object ... such as by 1/2px

                       

                      So, does that mean Illustrator will move 1/2 a pixel since it's vector like Inkscape? That is if you happen to use Illy as well

                       

                      I'm wondering why something that seems so simple to me doesn't have a more occams approach to a more functional solution ... ??  ie: like Inkscape ... or, again is it b/c Ps isn't a vector only program?

                       

                      Well, if you have noticed by my 1/2 witted response .... I'm a bit confused ... re: raster vs. vector ... but at least I'm heading down the path

                       

                      THANK YOU everyone for your help I really appreciate your time!!

                      Be Well

                        You are aware that moving pixel content by something other than full pixels would necessitate resampling and therefore could in case of repeated operations diminish image quality eight quick?

                          hey there...

                           

                          here's a big resounding NOPE ... lol ... I am still very new to Everything re: graphic design

                           

                          it blows my mind how much there is to learn ... from math I never Aced in school to understanding lighting, color and so on and so on

                           

                          but thank you!! i will keep that in mind.

                           

                          it's just that i had made a square shape and then a circle that i needed to fit in the center ~ the circle left more space to one side than the other and so i needed to move/nudge it over just a tad ... i'm a perfectionist or maybe just a little too OCD to be satisfied w/anything less than perfection

                           

                          i'll remember to keep my 1/2px moves down to a minimum

                           

                          Take care

                           

                          ps. what does 'eight quick' mean?

                            The resampling and diminishing quality is a concern for pixel layers. A Shape layer is a vector object similar to what you find in Illustrator and will not be damaged by a 1/2 px move. It's rasterized appearance will change when moved by a fraction of a pixel because the edges will be antialiased differently, but it is a non-destructive change. You can move it to and fro, scale it up and down and rotate it this way and that, and then it can be returned to its original form, unlike pixel layers.

                              A typo of "right quick" maybe?

                               

                              And I'll add +1 to conroy's comment:  There's no downside to moving a vector object half a pixel or moving it any number of times.  Perhaps there's been some confusion in the thread about just what it is you're trying to move/resize.

                                Yes.

                                 

                                I specifically stated that the deterioration applies to »pixel content«, but I think the OP never definitively stated that they are working with Vector Masks/Shape Layers.

                                  hey there c.pf...

                                   

                                  when i asked this question i am sorry that i didn't mention what i was working with ~ or what it was that i wanted to move/nudge by 1/2px.

                                   

                                  if i recall correctly at the time i had drawn a shape with the shape tool(s) ~ a circle inside a rectangle that i wanted perfectly centered.

                                   

                                  i was already too far along in my project to downsize the rectangle so that i would have been able to perfectly center the circle and a 1/2 move was just what i needed at that point.

                                   

                                  thanx again for all your help! this forum wouldn't be the same w/out you!!

                                   

                                  ps. now that i think of it i may have used a vector mask at this point. as usual i was following a tut. i'll find the link in my history and come back to post it if that'll help you understand better .... ????

                                   

                                  pps. long time since i've thought of this post ...

                                   

                                  so, not sure i definitively said ... but ... i believe i was in the need of moving a Vector object b/c as i've come to learn ... the shape tools are vector and that's what i was working with and what i needed to move

                                   

                                  just hope'n to clarify for anyone that may come to this post for help.

                                   

                                  oh, here's the link to the tutorial i was following ... http://psd.tutsplus.com/tutorials/drawing/draw-a-leica-camera/comment-page-1/#comment-3493 27

                                   

                                  if you scrolll down to step #29 you'll see the circle that i wanted dead center of the shape that ... uhhh, hangs down ~ ?? dunno how else to describe it.

                                   

                                  thanx again to everyone that helped me with this topic
