HR (High-Resolution graphics) is an image format that was used on TRS-80 computers. It is a bi-level 640×240 raw bitmap format. It is probably associated with the Grafyx expansion board and/or similar products, without which it was impossible to satisfactorily display such images.

HR files are usually exactly 19200 bytes in size, though we've observed some that are slightly larger.
