Editing images with an editing application
In addition to moving and making minor corrections to images, you can use the TouchUp
Object tool to take an image from a PDF document into Adobe Photoshop, Adobe
Illustrator, or another application to edit it. Once you complete the editing, you can place
the image or object directly back in the PDF document. You specify the preferred editing
applications in the TouchUp preferences.
Note: If the page contains transparency or logical structure, the page may look different
after you edit it in an editing application. Also, the appearance of the page may change
unexpectedly, because PDF tags have been removed. Their removal also affects the
behavior of the page for accessibility, reflow, and saving in different formats.
To edit one or more images or objects in an external editing application:
1. In Acrobat, select the TouchUp Object tool .
2. Select the image or object. Or Shift-click to select multiple images or objects.
3. Right-click (Windows) or Control-click (Mac OS) the selection, and choose Edit Image,
Edit Object, Edit Objects, or Edit Page. (The available command depends on what is
selected.)
Note: If the image can't open in Adobe Photoshop, verify that Photoshop is configured
correctly. If a message asks whether to convert to ICC profiles, choose Don't Convert. If
the image window displays a checkerboard pattern when it opens, the image data could
not be read.
4. Make the desired changes in the external editing application.
Note: If you change the dimensions of the image in Photoshop, the image returns to its
place in the PDF document, but the alignment may be different. Also, transparency
information is preserved only for masks specified as index values in an indexed color
space. Image masks are not supported. If you change image modes while editing the
image, you may lose valuable information that can be applied only in the original mode.
Editing in Photoshop and Illustrator from within Acrobat is a modal feature. If you
change the object selection, the editing session terminates, and any subsequent changes
aren't placed into the PDF document by Acrobat. Start a new editing session instead of
continuing to make changes.
5. If you are working in Photoshop, flatten the image. (Images must be flattened to be saved
in PDF Photoshop format.)
6. In the editing application, choose File > Save. The object is automatically updated and
displayed in the PDF document when you bring Acrobat to the foreground.
Important: For Photoshop, if the image is in a format supported by Photoshop 6.0 or
later, your edited image is saved back into the PDF document. However, if the image is in
an unsupported format, Photoshop handles the image as a generic PDF image, and the
edited image is saved to disk instead of back into the PDF document.
