BC7 Table 111 typo #11

Closed lewa-j closed 4 years ago

lewa-j commented 4 years ago

There is must be a typo in table 111. G1 and B1 should be 7 bytes long, but table says they stored in a bits 29..34 and 42..49, which is 6 and 8 bits long respectively.

Are you talking about Mode 5?

Please provide a pointer to the document that says G1 & B1 should be 7 bits.

lewa-j commented 4 years ago

Yes, mode 5. In the table 109, CB for mode 5 is 7. And according to text right after table 110, each color component is the same size (CB). And in the table 111, for mode 5, right after G1 and B2, numbers 0..6, meant 7 bit. But issue with offset on the left of them, (29..34, 35..41 and 42..49)

Fixed in the just published 1.3.1. Thanks for the report.
