Flash / SWF Previews. ABCpdf will automatically
create a still preview of Flash (SWF) movies.
The preview is what you will see if you don't have Flash
installed. It is what is used when printing PDFs. In general
it is what you will see if you open your PDF using a viewer
other than Acrobat.
The preview needs to be created at a certain resolution and
using content from a particular point in the movie. By default
the values are taken from the FlashPreviewTime and
FlashPreviewDPI Registry
Keys. However you can specify ABCpdf_PreviewTime and
ABCpdf_PreviewDPI attributes within your EMBED tag to override
these defaults.
Some movies take time to draw themselves because they use
script to determine how they should appear. You can use the
ABCpdf_PreviewWaitTime attribute to determine the time (in
milliseconds) that the movie will be given to initialize
itself before the preview is made.
For example to take a preview 2000 ms into the movie at 300
dpi you might use the following HTML.
<EMBED src="frogger.swf"
WIDTH="700"
HEIGHT="500"
ABCpdf_PreviewWaitTime="2000"
ABCpdf_PreviewDPI="300"></EMBED>
These attributes are useful if your settings are dependent
on the content within the movie rather than on the
PDF.
