示例1: toDImage
/**The resulting image will be 8-bit grayscale and if fVertical is
* true, then the image will be numPixels wide and dataLen() high (if
* fVertical is false, then the image will be dataLen() wide and
* numPixels high). The grayscale values for the profile foreground
* and background can be specified with fg and bg, respectively. (fg
* specifies the pixels that are part of the profile, bg specifies the
* pixels that are NOT part of the profile)
