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.
Software
- XnView tries to display HR images, but the version we tested apparently does not work correctly
Sample files
- http://www.classiccmp.org/cpmarchives/trs80/Software/Model%204/ ...
- A/Assorted HR Files.zip (some images are adult-oriented)
- G/Geography*.zip
- H/High Resolution Graphics Files.zip (some images are adult-oriented)
