ALAsset Image Size

Question

Given an ALAsset that represents a photo, is it possible to retrieve the size of the photo (height and width) without loading the image into a UIImageView and also without using the aspectRationThumnail method?

Answer 1

Just a note: iOS 5.1 introduces a new property dimensions for an ALAssetRepresentation instance. This returns a CGSize structure with the dimensions of the original image and might be the best solution for this problem in the future.

Cheers,

Answer 2

float width = asset.defaultRepresentation.dimensions.width;
float height = asset.defaultRepresentation.dimensions.height;

it fast, stable, and gives the actual dimensions. I've used it with ALAsset of videos.
