Read image from disk

Unity Engine
1

I was wondering if it would be possible to read all images in for example C:\images\ in an array, and then load them one by one by using path name (sort of like a simple picture viewer). I imagine the process would be something like;

  1. Read path to all files in folder and store those that ends with jpg or png in array.
  2. Load image function with applied path.
  3. Wait X seconds.
  4. Load next image.
    etc.

This only needs to run on Windows.

This should be a good start for you needs.

using UnityEngine;
using System.Collections;
using System.IO;
public class LoadImage : MonoBehaviour {

	// Use this for initialization
	void Start () {
		StartCoroutine("load_image");
	}
	
	// Update is called once per frame
	void Update () {
	
	}
	
	IEnumerator load_image()
	{
		string[] filePaths = Directory.GetFiles(@"C:\TEMP\", "*.png"); // get every file in chosen directory with the extension.png
		WWW www = new WWW("file://" + filePaths[0]);                  // "download" the first file from disk
		yield return www;                                                               // Wait unill its loaded
		Texture2D new_texture = new Texture2D(512,512);               // create a new Texture2D (you could use a gloabaly defined array of Texture2D )
		www.LoadImageIntoTexture(new_texture);                           // put the downloaded image file into the new Texture2D 
		this.renderer.material.mainTexture = new_texture;          	// put the new image into the current material as defuse material for testing.
		
	}
}
