Download Hexadecimal based PNG and convert to byte?

How can I download from my server and convert hexadecimal based PNG to byte (png file) used for texture?

Example output from server:
b'\x89PNG\r\n\x1a\n\x00\x00\x00\rIHDR\x00\x00\x01,\x00\x00\x00\xaf\x08\x06\x00\x00\x00G.\xe3\xb7\x00\x00\x1c\xfdIDATx^\xed\x9dw...' <redacted>

I tried 3 or 4 ways but struggling a bit.

Anyone have any examples?

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3. using UnityEngine.Networking;
4. public class MyBehaviour : MonoBehaviour {
5.     void Start() {
6.         StartCoroutine(GetTexture());
7.     }
8.     IEnumerator GetTexture() {
9.         UnityWebRequest www = UnityWebRequestTexture.GetTexture("http://www.my-server.com/image");
10.         yield return www.SendWebRequest();
11.  
12.         if(www.isNetworkError || www.isHttpError) {
13.             Debug.Log(www.error);
14.         }
15.         else {
16.             Texture myTexture = ((DownloadHandlerTexture)www.downloadHandler).texture;
17.         }
18.     }
19. }

 

Thanks Diego!

I should have mentioned that the PNG image is being stored in Redis, so we are only returning the Hex string from that hypothetical url.

 

The extension is secondary unless Unity expects that. But are you sure that you're giving out the proper header on the webserver? content-type: image/png
