问题
用 LabWindows CVI2012 做图像的形态学处理的时候，处理图像出现报错：
NON-FATAL RUN-TIME ERROR: "morph_pro.c", line 88, col 9, thread id 0x00000C28: Function imaqMorphology: (errorCode == -1074396154 [0xbff60406]). The image is not large enough for the operation.

原因
TempImage 和 DestImage 尺寸大小不一
解决
在形态学处理之前，利用 imaqSetImageSize () 函数将两张图像缩放到同一尺寸
imaqSetImageSize(TempImage,640,320); imaqSetImageSize(DestImage,640,320);
