Error converting `*gocv.NativeByteBuffer` to `string`

[tlalarus]

Description

I am encountering the following error:

cannot convert buf (variable of type *gocv.NativeByteBuffer) to type string

In Go, converting []byte to string is typically straightforward with type casting, but I am running into this error. My specific question is about how to convert a *gocv.NativeByteBuffer to string

Steps to Reproduce

func somefunc(img cv.Mat) {
  clone := img.Clone()
  buf, _ := gocv.IMEncode(".png", clone)

  strBytes := string(buf) // <- error occured
}

Your Environment

• Operating System and version: ubuntu 18.04 (docker)
• OpenCV version used: 4.10.0
• How did you install OpenCV? build from source of opencv github
• GoCV version used: 0.37.0
• Go version: 1.22.4
• Did you run the env.sh or env.cmd script before trying to go run or go build? no

Hi @tlalarus , gocv.NativeByteBuffer has a function GetBytes() []byte which is probably what you're looking for.

here's the doc
