I am trying to Take a screencapture and save it to a file in jpg format. I am following this example.
http://docs.unity3d.com/ScriptReference/Texture2D.EncodeToPNG.html
This is what I have so far:
string jpgFile = Application.persistentDataPath + "/scrn-1.jpg";
Texture2D tex = new Texture2D (Screen.width, Screen.height);
tex.ReadPixels (new Rect(0, 0, Screen.width, Screen.height), 0, 0);
tex.Apply ();
var bytes = tex.EncodeToJPG();
Destroy (tex);
System.IO.File.WriteAllBytes(jpgFile, bytes);
I have found that running this in Unity on iOS gives me:
JPEG parameter struct mismatch: library thinks size is 372, caller expects 360
However if I change the conversion to tex.EncodeToPNG(); and change the file name to .png everything works fine. I am not sure how to proceed any assistance would be appreciated. Thanks.
I found this, which lets you save it as .jpg. I normally just use capture screen and save as .png.
Here you go:
using UnityEngine;
using System.Collections;
public class HiResScreenShots : MonoBehaviour {
public int resWidth = 2550;
public int resHeight = 3300;
private bool takeHiResShot = false;
public static string ScreenShotName(int width, int height) {
return string.Format("{0}/screenshots/screen_{1}x{2}_{3}.png",
Application.dataPath,
width, height,
System.DateTime.Now.ToString("yyyy-MM-dd_HH-mm-ss"));
}
public void TakeHiResShot() {
takeHiResShot = true;
}
void LateUpdate() {
takeHiResShot |= Input.GetKeyDown("k");
if (takeHiResShot) {
RenderTexture rt = new RenderTexture(resWidth, resHeight, 24);
camera.targetTexture = rt;
Texture2D screenShot = new Texture2D(resWidth, resHeight, TextureFormat.RGB24, false);
camera.Render();
RenderTexture.active = rt;
screenShot.ReadPixels(new Rect(0, 0, resWidth, resHeight), 0, 0);
camera.targetTexture = null;
RenderTexture.active = null; // JC: added to avoid errors
Destroy(rt);
byte[] bytes = screenShot.EncodeToPNG();
string filename = ScreenShotName(resWidth, resHeight);
System.IO.File.WriteAllBytes(filename, bytes);
Debug.Log(string.Format("Took screenshot to: {0}", filename));
takeHiResShot = false;
}
}
}
If you just want any kind of picture I highly recommend this:
using UnityEngine;
using System.Collections;
public class ExampleClass : MonoBehaviour
{
void OnMouseDown()
{
Application.CaptureScreenshot("Screenshot.png");
}
}
Simple and effective.
