Converting .swf files directly to .pdf format.
Converting Adobe Shockwave Flash Movies directly to Adobe Portable Document Format (.swf to .pdf conversion) shouldn't be too difficult, as you will find several programs capable of such a conversion.
Try, for example, Adobe Acrobat, which allows users to create PDF documents from numerous sources, including .swf format. Simply use the 'File -> Create PDF from...' function.
Alternatively, you could try software like SWFTools, which enables users to extract .swf animations, and export them as .pdf documents.
