High Memory Usage about brightroom HOT 3 CLOSED

Do you try to use downsampled images for drawing? I looked at the code a bit and if I understood correctly, the full image is loaded into memory.

In UIImagePickerControllerDelegate we can use info[.imageURL] (unfortunately .imageURL available from iOS 11) and put it to apple downsample image function from WWDC 2018 (https://developer.apple.com/videos/play/wwdc2018/219 39 page in pdf)

@Banannzza
Thank you.
I tried to do that. However, I think I would like to use a large image to zoom that.
And I know that will use so many memory. (but why is this so huge? around 300MB!)
But It may have a good way of drawing. Do you have any good way?

If there is no way, we have no choice.
We will use a downsampled image from UIImagePickerController or PHAsset.

And, I did not know that .imageURL.
Definitely, we can resize that with ImageIO.

@muukii Yes, image decoding can cause memory problems. I don't know better way of drawing, but if it exists I will try to find it .
