![]() ![]() However, I am able to perform similar functions in Foxit and Nitro Pro quite easily - which I use on my other machines. ![]() But I suppose I could be experiencing a senior moment. I don't think I'm imagining it, since I worked with PDF's on a mostly daily basis. Whatever it may have meant technically, it did what I needed it to do. (3) In terms of what you describe, You flatten a document so that all the elements and layers become one on the page and uneditable sounds like a combination of the third and fourth interpretations of “flattening” per above, except that even if you “flatten” annotations and form fields into the content stream and then convert the page into a raster image within the PDF file, the content is still editable via Photoshop.ĭov - respectfully, while it has been quite a few years since I used Acrobat Pro, there was a "flatten" command in one of the main drop down menus. These options are not and have never been to my knowledge part of Acrobat Standard, a product aimed at the more simple needs of office workers and casual users. The flattening of annotations (including form fields) into the PDF content stream is available as a fixup under Preflight or alternatively can be performed via JavaScript. The layer flattening capability is found in the left hand pane's layer's palette drop down menu and is only active if your PDF file has more than one layer. Transparency flattening is a function within the Print Production Tools. (2) Each of these three functions can be accessed from functions from within Acrobat DC Pro. There was never a drop down menu in any Acrobat version to do this!! The third relates to taking annotations including forms fields (forms fields are actually PDF annotations) and merging (i.e., “flattening”) them into the PDF file's content streams - such “flattened” content no longer are editable as annotations or fillable/selectable as form fields.Ī fourth, much less common use of the term “flattening” is to convert all content on each page of a PDF file into one, big honk'in raster image in the mistaken belief that this somehow provides more “protection” to the PDF file (it doesn't but does significantly increase file size and decrease rendering quality). The second relates to reducing the number of “layers” defined in a PDF file to a single layer. The first relates to “transparency flattening” in which all objects that are not 100% opaque are “flattened” / blended into totally opaque objects. (1) Adobe endorses the comments of others on this thread that there isn't a single meaning to the word “flattening” when it comes to PDF! Regrettably, there are at least three separate meanings to the word “flattening.” On behalf of Adobe Systems Incorporated and as a member of Acrobat development organization, I feel that it is important to clean the air here: ![]()
