"System.ArgumentOutOfRangeException Invalid image type" when trying to encode a jpg image

[gentilijuanmanuel]

Hi,

I'm testing the library in a Xamarin.Forms project. I have a jpg image in my resources, and I want to encode it and get the encoded Stream.
In order to do that, I created an BlkImgDataSrc, then I get the byte array of the encodable source. Finally, I convert the byte array in a Stream.
The code:

var encodableSource = J2kImage.CreateEncodableSource(myStream);
var byteArray = J2kImage.ToBytes(encodableSource);
var encodedStream = new MemoryStream(byteArray);

I get an error in the first line: "System.ArgumentOutOfRangeException. Invalid image type Parameter name: streams".

Am I doing something wrong?

Note: I'm using CSJ2K 3.0.0.

Thanks in advance!
