| | |
| ==Problem==
| |
| In a Microsoft Office document, you see one of the following:
| |
| * ''"QuickTime(TM) and a TIFF (LZW) decompressor are needed to see this picture"''
| |
| * ''"QuickTime(TM) and a Photo - JPEG decompressor are needed to see this picture."''
| |
| * or translations like ''"Zur Anzeige wird der Quicktime Dekompressor "TIFF (LZW) benotigt"''
| |
| ...instead of an image.
| |
| | |
| ==Reason==
| |
| A combination of:
| |
| * The Mac version of MS Office, which allows embedding images via Quicktime
| |
| * Apple having omitted certain formats from Quicktime for Windows that are present in Quicktime for Mac {{comment|(including PICT, possibly the most common problem)}}
| |
| | |
| This basically means that you can add images to Office documents on Mac that will not be viewable on non-Macs.
| |
| | |
| ==Workarounds==
| |
| | |
| There is no immediate patch to read documents that show this problem, because this isn't fixed in any Quicktime version or patch (that I know of, to date).
| |
| | |
| | |
| One workaround is to go to the Mac you made the document on, and make sure the embedding is done with a more usual/portable image format.
| |
| | |
| Converting it while in the document may be nontrivial work, but you can often avoid re-embedding and re-positioning the image: [http://blog.pclark.net/2004/12/quicktime-and-tiff-lzw-decompressor.html Various in-document image-related actions] automatically mean conversion to a more usual format as a side effect. When this works it's probably the simplest fix.
| |
| | |
| | |
| | |
| If you have no access to a mac, you could choose to extract just the images, which you can do without access to a mac, via a trick: when you tell Office to export to a web page, images are either directly converted to something useful, or in the case of PICT/TIFF, images are saved to .pcz files, which are gzipped PICT files. {{comment|(You can extract the image from that <tt>.pcz</tt> using [http://www.rarlab.com/ winrar], [http://www.7-zip.org/ 7zip], [http://gnuwin32.sourceforge.net/packages/gzip.htm gzip for windows], or something like it)}}.
| |
| | |
| You should probably rename it to give it the .pict extension.
| |
| It may still be quite hard to view and convert this file.
| |
| In my case, the Quicktime for Windows image viewer crashed on it, and photoshop complained that it could only open raster PICTs.
| |
| | |
| [http://www.irfanview.com/ Irfanview] managed to view and convert it -- once the optional irfanview plugins were installed.
| |
| | |
| | |
| | |
| Further notes:
| |
| | |
| One page suggests that this is caused specifically by pasting such images into a document - which seems to suggesting that 'Insert image' may embed in a more portable way. I don't know how true that is{{verify}}.
