Obtaining the movie height & weidth of a Flash file is an easy task using the swfdump tool that comes as part of the swftools package. Here’s an example of how to invoke swfdump from C# and read out the height & width of a given Flash file.
Start out by downloading on of the swftools releases. I’m using the latest development snapshot. I’ll be using one of the Flash files I made in a previous blog post as a test file, but you can use any .swf file you want. The test Flash file is called test.swf.
Once you’ve extracted the swftools package and copied both the test file and the swfdump.exe file into your solution directory, we can now test it out manually:
By providing the -X and -Y switches swfdump only prints out the movie height & width. You can see all the switches on the swfdump man page. At this point it’s a simple matter of spinning up a swfdump process and parsing the output:
Width: 500 Height: 375
