Unable to use OpenCvSdk.Imgcodecs.Imdecode on MAUI iOS #5

Closed nk-alex closed 1 month ago

nk-alex commented 1 month ago

I'm using OpenCvSdk.iOS version 4.10.0 on my MAUI iOS project. I'm testing this on a real iphone. I'm trying to load a byteArray into a Mat object:

byte[] image = ....
NSData conversion = Foundation.NSData.FromArray(image);
Mat matImage = OpenCvSdk.Imgcodecs.Imdecode(new Mat(1, image.Length, CvType.Cv8uc3, conversion), (int)ImreadModes.Unchanged);

But I'm not able to successfully run OpenCvSdk.Imgcodecs.Imdecode. No exception is thrown. Application just gets killed with the following message:

The app has been terminated.

Am I missing something?

Yes I can reproduce this. Should be fixed with OpenCvSdk.iOS version 4.10.0.1 let me know if it works thanks.
