    Exporting Image from Acrobat

    ZenDao Community Member

      I have an InDesign document that has two imbedded JPG images. One image still retains the link to the original file, the second image is no longer linked to the original file and does not exist. Let say image one is of a tree and the second image that is no longer link is of a car just to aid in this discussion.

       

      When I generate a PDF and run the "Export All Images" function from within Acrobat, it does export the two JPG images.

       

      How is Acrobat able to export the second image (car) if the original source file no longer exists?

       

      And the other image (tree) that is still linked in the InDesign file. It seems like Acrobat exports that image at the dimension and size set in the InDesign file. Which is totally different from the original JPG file if you were to open up both images in Photoshop.

       

      Just trying to get a better understand on what Acrobat exports when using the "Export All Images" function.

          Acrobat is simply exporting the embedded version of the graphic from within the PDF file. InDesign embedded it according to the settings you used on the document at the time, so it won't usually be the same as the original image file InDesign was linking to.

            When you generate the PDF, all of the image data is stored in the PDF and in no way relies on an external file. When you export an image from the PDF, it takes the image data and generates a new file that will necessarily be different than the original source file, for a number of possible reasons (different physical size [as in your case], different compression method, downsampling, etc.)
