寬度（-1）和高度（-1）不能<= 0

總是收到在處理一些奇怪的錯誤，使用以下的微小的一段代碼：寬度（-1）和高度（-1）不能<= 0

void setup() { 
    size(200,200); 
} 

void draw() { 
    background(0); 
    loadPixels(); 
    updatePixels(); 
}

錯誤：（含堆棧跟蹤）

現在起初我以爲這是一個bug，因爲之前有另一個bug在我重新啓動Processing時消失了。它似乎仍然沒有很好的Mac OS X Lion支持（這就是我正在使用的）。但是我嘗試了穩定版本和預發行版本，兩者都有相同的錯誤。有沒有人得到這個？有誰知道如何修理它？我是否需要安裝更好的JDK或其他？

請顯示異常的堆棧跟蹤。 – 2011-12-26 17:41:31

當然，添加了堆棧跟蹤。 – slartibartfast 2011-12-26 17:47:35

「背景」，「loadPixels」和「updatePixels」是做什麼的？如果你能向我們展示一個簡短但完整的程序來證明問題，這將有所幫助。 – 2011-12-26 17:56:19
