What is an HRF file?
Bitmap image stored in a proprietary format developed by Hitachi; may contain a color, grayscale, or monochrome raster graphic; used to store scanner output data.
HRF files were supported by several older programs, including Hitachi's CADCore application. They can still be viewed with programs such as Intergraph's SmartPlant Markup.
