问题情境：
给picturebox赋image属性，我用一下代码，出错：
Bitmap theBitmap = convertCameraData.display(rawDataArray, height, width, rawImageArray, rgbPalette_256, backgroundTemperature);
if (theBitmap == null) { return; }
form_Main.pictureBox1.Image = theBitmap;
困境辨析：
把bitmap赋给pictureBox1.Image不正确，应转为image再进行赋值。
Bitmap theBitmap = convertCameraData.display(rawDataArray, height, width, rawImageArray, rgbPalette_256, backgroundTemperature);
if (theBitmap == null) { return; }
form_Main.pictureBox1.Image = new Bitmap(theBitmap);
