Rockbox mail archiveSubject: Scrolling thread on iriverScrolling thread on iriver

Date: Tue, 14 Jun 2005 11:50:31 +0100 (BST) Am I right in thinking that scrolling text on iriver causes it to 'puts' the entire string each time it scrolls it, even by one pixel? Is that efficient? Seems to me that it would be better to implement the scroll using something like a memcpy from the framebuffer and just use the string-print logic to print out the far right-hand column that scrolls in (or left hand if scrolling right). I bring this up because I've noticed the scrolling can be a bit jerky on iriver when scrolling e.g. three lines of text simultaneously in wps. Wondering if optimising the lcd driver code a bit might help d _______________________________________________ http://cool.haxx.se/mailman/listinfo/rockbox Received on 2005-06-14 Page template was last modified "Tue Sep 7 00:00:02 2021" The Rockbox Crew -- Privacy Policy |
