PICON to RB conversion is the process of transforming image files from the PICON format (a platform-specific or legacy pictogram/icon raster format) into the RB format (a raster bitmap image variant used by certain imaging tools and devices). This conversion re-encodes the pixel data, metadata, and compression settings so the resulting RB file is compatible with software and hardware that require the RB image container.
