Three kinds of situations of pixel can reserve the first row of upper part and last column on the right, then from planning path
The reserved pixel that the pixel of data input is adjacent starts, and the data of the pixel based on the data input in planning path pass
Defeated sequence determines data transfer sequence according to the adjacent principle of head and the tail for reserved pixel until some reserved pixel and rule
Draw path in data output pixel it is adjacent when stop, then since some pixel, based in planning path
The data transfer sequence of the pixel of data output determines data according to the adjacent principle of head and the tail for remaining reserved pixel
Transmission sequence.
Wherein, in step S100 and in step S200, described utilizes the two kinds of base pixel modes pair established
