How to load png then convert to sprite?-CodePudding

I need to load a png image from a screenshot then convert it to sprite and put it into an image. I have code in below but it has seen no work?

why?

string pngpath = Application.dataPath   $"/Screenshot{index}.png";
Sprite sp = Resources.Load<Sprite>(pngpath);
child.GetComponent<Image>().sprite = sp;

public IEnumerator CaptureScreen()
    {
        // Wait till the last possible moment before screen rendering to hide the UI
        yield return null;
        canvan.GetComponent<Canvas>().enabled = false;

        foreach (GameObject i in Ball)
        {
            i.GetComponent<Renderer>().enabled = false;
        }

        // Wait for screen rendering to complete
        yield return new WaitForEndOfFrame();

        // Take screenshot
        ScreenCapture.CaptureScreenshot(Application.dataPath   $"/Screenshot{index}.png");

        // Show UI after we're done
        canvan.GetComponent<Canvas>().enabled = true;
        foreach (GameObject i in Ball)
        {
            i.GetComponent<Renderer>().enabled = true;
        }
        index  ;
        PlayerPrefs.SetInt("index", index);
    }

CodePudding user response：

You are not converting the png to sprite, try this.

string pngpath = Application.dataPath   $"/Screenshot{index}.png";
byte[] filedata;
filedata = System.IO.File.ReadAllBytes(pngpath);
Texture2D text = new Texture2D(2, 2);
text.LoadImage(filedata);
Rect rec = new Rect(0, 0, text.width, text.height);
Sprite sp = Sprite.Create(text, rec, new Vector2(0, 0), 0.1f);
child.GetComponent<Image>().sprite = sp;
