media file formats in powerpoint xml documents RRS feed

  • Question

  • Image files in ppt/media are stored in tiff format. Using other image formats seems to generate an error on opening the powerpoint file. Are other image formats allowed, or must all images be converted to tiff format?

    Thanks,

    Michael

  • Hi mtmccarthy, 

    Other formats are allowed but need to be specified by extension in the [ContentTypes].xml part. Please refer to ISO/IEC 29500-2: 

    10.1.2.2 Content Types Stream Markup
    This should address your situation. If you have just changed the part from a .tiff to .jpeg and not added to the package [ContentTypes].xml like this:

    <?xml version="1.0" encoding="UTF-8" standalone="yes"?>
    <Types xmlns="http://schemas.openxmlformats.org/package/2006/content-types">
        <Default Extension="png" ContentType="image/png"/>
        <Default Extension="jpeg" ContentType="image/jpeg"/>
    

    then this may be why you see the error. Can you confirm this?

  • Hi mtmccarthy,

    Since you've not replied for a couple of weeks, I'm assuming that you've either figured this out or my answer led you to a solution. I am considering this issue resolved for now.
