Image Magick - Need Command Line Code (Linux) For 4 Effects

Hello, I require the command line code (for linux) for a small number desired effects for an application I am developing. These effects are applied to the borders of an image that a user uploads and the effects are processed by the image magick command line. I need the command line code for the effects so expertise in image magick is required since these effects may be complex . Communication is a top priority and good work done will lead to more work and a bonus. Please send me a message if interested and I will provide a better description of the effects if needed. Thank you
