(#5swkiqa) @prologic@twtxt.net It’s quite similar to how escape sequences work in a terminal. ASCII text is printed as ASCII text and then an escape sequence can make it bold or underline and so on. Other escape sequences allow you to say “the following $n bytes are part of a bitmap image”, and then this gets printed at whatever the current position is (somewhat similar to SIXEL in a terminal).

It’s just that the units are a bit weird, because this is all done in bloody inch. 😅
