Each PDF file encapsulates a complete description of a fixed-layout flat document, including the text, fonts, graphics, and other information needed to display it.Ī KEY file contains slides that may include text, images, shapes, charts, tables, transitions, audio, video, and notes. The Portable Document Format (PDF) is a file format used to present documents independent of application software, hardware, and operating systems. Keynote is a presentation software application developed as a part of the iWork productivity suite. for its macOS and iOS operating systems, and also available cross-platform through the iCloud website. IWork is an office suite of applications created by Apple Inc. Lines and curves will render smoothly even when scaled, while bitmaps will (obviously) not.Application/pdf, application/x-pdf, application/x-bzpdf, application/x-gzpdf It’s also worth noting that a PICT file containing drawing commands will render differently depending on the output device. A file that contains drawing commands is only going to be convertible if the app doing the conversion supports the commands used by the file. A file that just contains bitmap data will be easily convertible to anything. So I’m not surprised that some files can’t be converted by all apps. In order to support the full capabilities of a PICT file, converter software needs to implement the entire QuickDraw API, including any bugs that apps may expect to be present. In the past, when MacOS used QuickDraw (Classic and I think also Carbon), this was a quick and easy file format to support. They are conceptually meta-files (strictly speaking, a file with one or more PICT resources in its resource fork) containing sequences of QuickDraw graphic primitives which are used to render the file contents on different devices (e.g. If I remember correctly, PICT files do not necessarily contain pixel data. This is somewhat tedious, but a lot less tedious than re-creating the entire Keynote file. Once the elements of your COPY of the Keynote file is completely updated, after testing it, you can discard the original. Then “replace” the videos within Keynote to retain all other characteristics you’ve previously applied to them. With videos, use “Handbrake” (another outstanding free and widely used utility) to convert old video formats into more modern ones readable by Keynote. You can use the same procedure to replace problematic videos. Keynote will replace the problematic PICT with the new jpeg, and will retain all other characteristics you gave to the original PICT (such as borders, shadows, animation, etc.) When replacing the image, choose the newly-converted version of the image from the folder created earlier by The Unarchiver. Once you have converted the problematic PICT elements… open the COPY of your Keynote file and navigate to the problematic slides.Graphic Converter (mentioned by a previous commenter) is an excellent one, but there are others. There are lots of utilities which can do this. Convert those PICTs to a newer graphic format, such as jpeg. It will create a folder containing all the elements of your Keynote file. Allow “The Unarchiver” to open your copy of the problematic Keynote file. CTL-CLICK on the Keynote file and choose “Open with…” Navigate to your installed “The Unarchiver” application.Download and install “The Unarchiver,” a free, Apple-qualified utility for disaggregating Mac document files such as Keynote files.Work on a COPY of the affected Keynote file, not the original.Mostly, I have tackled the problem with the following steps: It affects PICTs and it also affects some older video formats (such as “RealMedia” from back in the day). I have had this problem in older Keynote presentations for several years (because I’m a regular “updater” to newer MacOS versions). I know the format (one of the oldest Apple graphical formats, if not the oldest one) is depreciated, but I am unpleasantly surprised that all of a sudden and without warning they have been replaced by a rectangle with a cross in it.ĭoes anyone know of a trick or utility to convert those old Keynote presentations? Making presentations with Latex is a drag, but at least there is a promise of backwards compatibility… The problem appears to be that there are many. I’ve stopped using MS Word long ago because of compatibility issues, but Apple is now following the lead of Microsoft, apparently. What gives? Keynote can no longer read of half of my presentations! It is those unforeseen consequences that I hate. However accepting the inevitability and after having relegated the functionalities of some 32-bit applications that I depended upon to Linux machines and having found replacements for others, I decided to give it a go. For some people such upgrades may be a source of excitement, but I dread them. After having postponed transiting to 64-bit as long as I could, I finally did it.
