Hi, All,  
i am working on an application that will allow my users to upload  
files and then display these files on a generated page. file types  
that they will be uploading include flash SWF files. is there any way  
of including SWFs dynamically with ROR so that the dimensions of the  
file are set. in PHP there is the getImageSize function that can read  
the dimensions of a swf. any such equivalent in Ruby or Rails … ?  
any sort of solution would be great such as one involving the swf  
object or some rails function like ‘flash\_for’ which someone mentioned  
but I cannot find any info on… ANYONE HELP!!!

Correction: that is a GD function, so you will need to find use  
something  
like ruby-gd perhaps

I had faced a similar requirement but have yet to find a solution.  
However in practice it is better  
to set a fixed dimension (either width or height) and set the second  
base on a desired aspect ratio  
(4:3 or 16:9).

I’ve used this approach here:
