How to make a picture look pixelated.

[zoopboy]

Thanks for all the suggestions guys, but to clarify, this is an effect I need to use as an integral part of the game. It cant be done as an external process then loaded into the game. Im essentially trying to show a picture in game that has 3 different stages of pixelation, the image is loaded in by the player during the game, so I never get to see the image, let alone have access to it, to do any sort of external process.

AyreGuitar: I did notice the screen capture ectension was not finished for iOS. thanks again for the suggestions.

Does the viewport object work in iOS? You could try it with that. Just scale down your object while keeping a viewport on top of it at a constant size, but shrinking the source area.

UltimateWalrus - No the viewport object hasn't been converted for iOS Exporter AFAIK. I've never used it before, but looks interesting. Might not be that hard to write the iOS version.

zoopboy - I have a more advanced version of the Screen Capture Object for iOS that might suit your needs, but I'd been waiting for a new Beta that allowed the Active Picture to load from places than just the app bundle or photos (ie the app's Documents and Caches folders). Looks like Beta10 after 254 does this now, so may have to do some tweaks and upload a new version of the Screen Capture object. It can now do Window (screen without black bars) and Frame (specify origin and height/width)

There is a way of capturing so the user can't see what's being captured, but it's a little hacky at the moment. I just cover that region of the screen with a large iOS button that's the same colour as the background and don't capture the UIKit layer.
I suppose I could make it less hacky by using the "Capture high colour modes in 24 bits" tick box to turn it on or off...

When I have some time, I'll look into it and post a new version in the iOS Extensions forum.

zoopboy - I've posted a newer version of the Screen Capture Object for iOS I did a while back here:

Whilst the user will see what you're capturing, you should be able to evaluate whether this will give you the pixellation effect you're after. You'll need to capture the user selected image first then load into 3 different sized Active Pictures and capture those as your 3 images, then reload into Active Pictures with resize as Fast to display them.
I'll post a newer version that allows for hidden capture when I have time.

AyreGuitar, you are a hero, regardless if it works or not. Thanks for all the help. I will try the screen Capture Ext.

Thanks again to everyone.
