使用PImage獲得最新的文件夾（處理）

即時通訊試圖找出如何挑選出最新的文件夾加載到PImage。我無法想出一個辦法。使用PImage獲得最新的文件夾（處理）

我有兩個小品，一個是創建一組圖片，並在加載它們之一。這是加載它們之一。

一個新文件夾我的草圖中每次創建數據文件夾其他草圖運行。我需要挑出最近創建的文件夾並將其加載到我的PImage中。它看起來像http://imgur.com/a/u1jF0
因此，下一個文件夾的名稱將被稱爲test_segments2，然後測試segments3 ...等等。

CODE：

final int len = 25; 
final float thresh = 170; 

boolean newDesign = false; 
PImage pic; 

ArrayList<PImage> imgContainer; 
int n = 1; 

void setup() { 
    size(800, 800, P2D); 
    colorMode(RGB, 255); 
    background(250, 250, 250); 
    rectMode(CENTER); 
    // imageMode(CENTER); 

    pic = loadImage("hand.jpg"); 
    pic.resize(width, height); 
    color c1 = color(200, 25, 25); 
    color c2 = color(25, 255, 200); 

    imgContainer = new ArrayList<PImage>(); 
    PImage pimg1 = loadImage("THIS IS WHERE I NEED THE PATH OF MOST RECENT FOLDER CREATED TO GO"); 
    pimg1.resize(50, 50); 
    noLoop(); 
    noStroke(); 
} 

void draw() { 
    if (newDesign == false) { 
     return; 
    } 

    pic.loadPixels(); 

    for (int y = 0; y < height; y += 40) { 
     for (int x = 0; x < width; x += 40) { 
      int index = y * width + x; 
      color pixelValue = pic.pixels[index]; 
      color rgb = pixelValue; 
      int r = (rgb >> 16) & 0xFF; // Faster way of getting red(argb) 
      int g = (rgb >> 8) & 0xFF; // Faster way of getting green(argb) 
      int b = rgb & 0xFF; 

      // How far is the current color from white 
      float dista = dist(r, g, b, 255, 255, 255); 

      // 50 is a threshold value allowing close to white being 
      // identified as white 
      // This value needs to be adjusted based on your actual 
      // background color 
      // Next block is processed only if the pixel not white 
      if (dista > 30) { 
       float pixelBrightness = brightness(pixelValue); 
       float imgPicked = constrain(pixelBrightness/thresh, 0, n - 1); 
       image(imgContainer.get((int) imgPicked), x, y); 
      } 
     } 
    } 
} 

void mouseReleased() { 
    newDesign=!newDesign; 
    redraw(); 
}
