  • I don't know if or if not this is possible from within grafx2, but your manual workflow can be simplified dramatically by using image magick. The following command will do all your steps automatically and reproducibly:
  • ```
  • convert test.gif -transparent white -gravity south -chop x60 -trim output.png
  • ```
  • > ![resulting image after conversion with transparent background and cropped to the content](https://powerusers.codidact.com/uploads/3xw8uxld7qy070eyh2o2r8g2hn69)
  • Explanation of the steps:
  • - `convert`: calls the convert command from the image magick bundle (it may be called differently if you use windows)
  • - `test.gif`: name of the input file
  • - `-transparent white` replaces the white background with a transparent background
  • - `-gravity south -chop x60`: cuts off 60 pixel from the bottom of the image to get rid of the black bar (the exact number might need find tuning, that was just my quick estimate)
  • - `-trim`: will remove all superfluous space around your shape
  • - `output.png`: name of the resulting file
  • (depending on how you make your documents, one might even incorporate this conversion into your document making workflow)
