Speeding up the display of a large jpg image

[Mag]

Hi all,

I'm creating a gallery with a single card and an image control. When user swipes a new image is displayed setting fileName property of the control (I'm using a lock screen with effects to give the perception of switch from an image to another). Somebody of you has find a way to improve the speed of displaying a large image in a image control?

Hi,

How big is your image, because we're doing the same on iOS (iPhone), without any performance problems.

Great to hear this.

The image control size depends by the width of the device's display, for example 1600 px in a Kindle Fire.
The image file size depends on device's camera, for example 2400x3200 px in a Kindle Fire.

There's just a little 'late, I'd love if you could eliminate.

You might want to experiment with the "prepare image" command. That preloads them.

Thank you, it has to be used a bit before the image is actually needed right?

Right, you'd probably want to preload the next one at the end of the handler that displays the current one.

Did you change layer mode to Dynamic or Scrolling?

I read something about it, it changes the update process and it's recommended to change it Dynamic for games and frequent updates.

Interesting, I will read up on this.
