Long time no post! Been a bit crap the last year or so, had some serious health issues but a message from Arcadian gave me the impetus to get off my backside and work on Legend again. I've decided to rework the graphics for VideoNULA. Here are some of them:
I'm using 15 colours, plus 1 reserved for sky effects (the sky will darken depending on time of the day), or as a masking bit. One of the problems I have is that I cannot use the RLE schema I had if I'm using the whole palette. So having written some nice efficient sprite routines, I'm going to have to rewrite them. Given the volume of graphics, I still want some compression, so here's some pseudo-code for what I came up with:
GET next byte
IF byte &F0 = &F0 THEN
NEXT byte AND &F are RLE encoded pairs
FOR I = 1 TO byte &F
GET counter byte
GET pixdata byte
FOR J = 1 TO counter: WRITE pixdata: NEXT
NEXT
ELSE
NEXT byte are non encoded pixels
FOR I = 1 TO byte
GET pixdata: WRITE pixdata
NEXT
END IF
RETURN TO START
I would only RLE encode if the saving on the next X encoded pixels > 3.
Any comments and ideas would be gratefully received.
