Create Thumbnail from SWF?

I have numerous SWF files. How can I generate jpg thumbnails from each swf? Preferably I'd like to generate a thumbnail from the middle of the SWF (For example, what it'd look like if you played it half way through)

I assume you mean from within flash. bitmapdata class might be some place to start looking.

No, I need to create it outside of Flash.

For instance, a user uploads a SWF file to my website, I need a PHP or something to create a jpg screenshot.

Hi,

realistically, the only software that will display every swf correctly is flash player. While it is probably possible to convert a static swf into, say, a pdf, what you actually see might be largely determined by actions.
The only realistic way to approach that target would be a setup that combines a flash player with a screen capture tool

if swf files basis on FLASH video, you can try to use VideoCharge for extract frames and create thumbnails.

hi there. thx for all the solutions provided by you guys .
Once I used Adobe Acrobat. but it becomes more and more expensive for public users who haven;t got many swf files to process.
Even some workers in this erea choose a third party freeware.
As for me,Im willing to use thumbnail creating dll which is capable of generating thumbnail for SWF.

Best regards.
