Tips / Tricks for displaying images quickly

[bialio]

Refering mostly to fanart here, specifically on extenders.

I'm putting together an update for one of my SageMC themes, and I'm trying to get the best performance I can on my extenders. The background images (which are typically 16x9 type jpegs) seem to introduce some lag when scrolling through a list.

The images aren't full screen - they are actually about 46% of the screen width. Given that extenders have a 940x540 UI, I've sized the images down to 440 width and display them as is (ie no scaling) - but it still seems to lag a bit. Are there any other ways to speed things up?

btl.

there are two ways I go about this

the best is delay the loading of the background fanart by 5 seconds after user inactivity has stopped. This will speed up scrolling greatly

if that doesn't work use the Phoenix API to scale the image size down to 50% or so.

The first option is best IMHO me and razor both use it in our addins.

Easiest way is
fork
checkitem = focuseditem
wait(timetowait)
if checkitem== focused item
then set variable and refresh

do it in a focus gained or listener hook is the best

let me know If you have any questions on my phone so may not have been clear.
