This is pretty simple using the Image library commands...

Code: Select all

UseGIFImageDecoder()

gif=LoadImage(#PB_Any,"mygif.gif")
If gif
  frames=ImageFrameCount(gif)
  If frames>1
    For idx=1 To frames
      SetImageFrame(gif,idx-1)
      delay+GetImageFrameDelay(gif)
    Next
  EndIf
  
  Debug "Frames: "+frames
  Debug "Total ms: "+delay
  
  FreeImage(gif)
EndIf

You need to read the headers of each frame and add the DelayTimes.

Ok, to late.
