Android Utils missing from org.bytedeco.opencv

[nofurylion]

Hi,
Build target : Android 21+
Language : Kotlin
My gradle :

implementation group: 'org.bytedeco', name: 'opencv', version: '4.1.0-1.5.1'
implementation group: 'org.bytedeco', name: 'opencv', version: '4.1.0-1.5.1', classifier: "android-arm"

When using Utils.bitmapToMat(param1, param2), the only available Utils are from package org.opencv.android. I cant find Utils from package org.bytedeco.opencv.android .

This lead to error since param2 will require org.opencv.core.Mat instead of org.bytedeco.opencv.opencv_core.Mat

I've tried rough casting it like param2 as org.opencv.core.Mat but it lead to error "unable to cast".

Are there any alternative way to convert bitmap to mat easily?
and also why package org.opencv.* still exist in the library? Is that how wrappers work?

We can convert between Mat objects of the two APIs with OpenCVFrameConverter.ToMat and OpenCVFrameConverter.ToOrgOpenCvCoreMat. See this unit test for an example:
