    Preserve image dimensions

    trianita

      Hi I am about to do my ACE exam for ID

       

      So i have been studying away - and am not happy with the 'preseve image dimension' option

       

       

      Here is a practice question from the adobe site (with supplied answer)

       

      4.1 Given a scenario, determine the best settings for choosing and placing an image


      You want to replace an image from a selected frame. The new image is larger than the original
      image. You want the new image to be imported at the same scaling percentage as the original.
      What should you do?

       

      A. hold down Shift as you click the Relink button in the Links panel
      B. hold down Option/Alt as you click the Update button in the Links panel
      C. before replacing the image, deselect Preserve Image Dimensions When Relinking in the
      File Handling pane of the Preferences dialog box
      D. before replacing the image, select Preserve Image Dimensions When Relinking in the File
      Handling pane of the Preferences dialog box

       

      Correct answer: C

       

      BUT it says this in the help file

       

      Choose how relinked graphics are scaled

       

      When you relink to replace one graphic with a different source file, you can keep the image dimensions of the file that’s being replaced, or you can display the incoming file in its actual dimensions.

       

      1. Choose Edit > Preferences > File Handling (Windows) or InDesign > Preferences > File Handling (Mac OS).

      2. Choose Preserve Image Dimensions When Relinking if you want images to appear at the same size as the images they’re replacing. Deselect this option to have relinked images appear at their actual size

       

       

      Is this a contradiction or am i being thick

       

      Thanks

          I'd say the help file is correct, and the person who typed up the practice question got it backwards. Can hardly blame them. Image dimensions and scaling percentage are two different things, but I believe the help excerpt accurately portrays the behavior.

            I would agree that the correct answer is C, and further, I'd say the help file is incorrect (and probably should be reported to Bob Bringhurst). The behaviors you should see are either maintaining the image dimensions (NOT scaling percentage) or maintaining the scaling percentage that has been applied in the frame. If you try it you'll see that's how it actually works.

             

            The only time an image would be placed at 100% during a re-link is if the one it is repalcing is also at 100%.

              Bob, John

               

              I have placed a graphic and scaled it so it is

               

              W=80.4mm

              H=479

               

               

              With preserve image dimensions OFF

               

              I import another image

               

              now

              W= 286

              H=1509

               

               

              With preserve image dimensions ON

               

              I get

              W=80

              H=423

               

               

              As far as I am concerned neither has preserved the image dimensions

                80 and 80.4 are pretty close. I wonder if the difference might be due to a resolution issue that requires an adjustment to get a full pixel, though .4 mm is pretty big in that respect. Are you patched to 6.0.4?

                    You marked my response as correct. Does that mean you updated to 6.0.4 and things are working as they should?

                      Sorry Peter

                       

                      I think I must have hit it by mistake

                       

                      But just experimented with it on 6.04

                       

                       

                      I have image 210x297

                       

                      I replace this with preserve image dimensions ON -new image is 210x1776

                       

                      I replace this with preserve image dimensions OFF -new image is 25.013x211.552   --- which is the same size as if imported into a new frame

                       

                       

                       

                      Doesnt this make the help file correct and the adobe practice exam wrong ?

                       

                      I assume the original to be the image that is being replaced

                        Did you scale the first image in your second experiment? The new one should come in at the same SCALE, so if you scaled the original to 50% the repalcement should also be at 50% of its actual size.

                         

                        I've just done this test again for the second time to reconfirm that this is the way it works. You might want to try it for yourself. Place an image at 100% for reference, then make two copies, one at an enlarged scale and one at a reduced scale. Relink all three to the same new image and check the scaling percentages. They should be the same as the original images when "Preserve Image Dimensions When Relinking" is not selected.

                         

                        You should see the same behavior if you select the frame and choose Place instead of relinking.

                          I cant get this to work

                           

                          When I replace the three images with the same file, they all stay exactly as they were regardless of whether preserve image dimensions is on or off

                           

                          What I have noticed is that if I replace one image with another

                           

                          with preserve dimensions on the new image has the same width as the the replaced one

                           

                          with it off the new image comes in with he same scaling as the replaced one had

                           

                           

                          any ideas

                            Right, that's what's supposed to happen, and it NOT what the help says.

                              My eps image was at 100%. I had the Preserve Image Dimensions checked on. I was given a new eps with a minor change. I assumed the relinking would also be at 100%. But in came in at 105%. If the Preserve Image is on then whether I put my original at 95% or 100% that is what my relinked image should also come in at. But it did not. Does any one know what is going on. I have had this happen a few other times since I have been using InDesign CS4.

                                Preserve Dimensions does exactly that. The new image wil be as close as possible in size on the page as the old one was. This is not the same as preserving the scale. if you replace a 2" wid image with one that is only 1" wide, it will be scaled 200% to 2"

                                    Appeared in your history how? this is a really old thread that hasn't been active, so it's probably a glitch inthe forum software and nothing we'll be able to fix easily. Is it causing you some sort of problem?

                                      No problem at all, just thought it might be the start of one.
