Uh, Rotate and Mirror can't be buttons in the Dialog Box, for the simple reason that .BXPs can't have dialog boxes or any other user-interface (at least not directly, or without bypassing the API which would greatly interfere with future portability). They are bitmap file import/export filters ONLY. The usual workaround is to have a companion .PXP which presents a dialog box and saves parameters into a file which the .BXP then reads. Kaos Gradient Explorer for 3DS is an example of this. It has a .PXP with its nifty KPT-type user interface, which saves the gradient you design into a parameter file with a .GRA extension. Then a GRA.BXP actually reads that parameter file and generates the actual gradients you specified, creating the actual bitmaps to be used as maps, backgrounds, Video Post layers, etc.
