desiredWidth and desiredHeight about splat HOT 7 CLOSED

And on Android I think this code can be changed from:

bitmap = await Task.Run(() => BitmapFactory.DecodeStream(sourceStream, noPadding, opts));

To

bitmap = await BitmapFactory.DecodeStreamAsync(sourceStream, noPadding, opts);

@dylanvdmerwe Basically, the resize is a JPEG loader optimization that is present on certain platforms and not others; i.e. we never load the full uncompressed bitmap, then attempt to scale it down - because it's not present on iOS, we don't want to load a full size, blow available memory, then return you a scaled one. I do agree that this is a bit misleading API though

I see what you mean. But the best we can do is wrap it in an autorelease pool for now? Rather than just ignore it.

                        using (var ns = new NSAutoreleasePool())
                        {
                            var data = NSData.FromStream(sourceStream);
                            var sourceImage = UIImage.LoadFromData(data);


                            UIGraphics.BeginImageContext(new SizeF(desiredWidth.Value, desiredHeight.Value));
                            sourceImage.Draw(new RectangleF(0, 0, desiredWidth.Value, desiredHeight.Value));
                            var resultImage = UIGraphics.GetImageFromCurrentImageContext();
                            UIGraphics.EndImageContext();
                            return resultImage;
                        }

I'm not suuuuuper excited about that, any other ideas?

I've done quite a bit of reading today about this and on iOS I do not see anything similar to the Win Phone or Android methods. But at least using a manual auto release pool the memory is quickly recovered. This is very similar to how you shrink images you've taken on the iPhone camera (high res) before sending them via the web.

But do check the change I suggested for Android above.

👍 on that, I think that must be a new method they added

The android loader doesn't resize the image either, it is passing the desiredWidth and desiredHeight variables to the outHeight and outWidth parameters of the opts bag, these capture the size of the image, not modify.
