Convert RawImage to Texture2d

since I cant find a way to make webcamtexture rotate to portrait when I make it as texture2d, I want to use rawimage to make texture2d.. is it possible?

I tried to use this code

Code (CSharp):

1. Texture2D frameTexture = (Texture2D) frame.mainTexture;
2. Texture2D texture = new Texture2D(frameTexture.width, frameTexture.height);
3. texture.SetPixels(frameTexture.GetPixels());
4. texture.Apply();

but I getting "InvalidCastException: Specified cast is not valid."

 

I had a similar problem, ended up using the solution in:
https://stackoverflow.com/questions/58844351/converting-rendertexture-to-texture2d-in-unity-2019

just use Texture instead of renderTexture

 

public RawImage profileImage;
private Texture2D textureImg;

 

convert raw image into texture

public RawImage profileImage;
private Texture2D textureImg;

textureImg = profileImage.texture as Texture2D;

WWWForm form = new WWWForm();

byte[] imgByte = textureImg.EncodeToPNG();

Debug.Log(profileImage);
form.AddBinaryData("myimage", imgByte, "imageFromUnity.png", "image/png");
