Specific embodiment
The principle of nine figures of point is introduced herein.Fig. 1 is that nine diagram of point is intended to.As shown in Figure 1, by manually scheming in png
The surrounding of piece draws the marking line of four black.Wherein, the effect of two transversal stretching marking lines of top is to indicate png figure
Piece horizontally telescopic regional scope；The effect of the longitudinal extension marking line on the left side is to indicate png picture in the longitudinal direction
Telescopic regional scope；The effect of spacing marking line is to indicate using png picture as background, in the longitudinal direction in the longitudinal direction on the right
The regional scope of displayable content；The effect of spacing marking line is indicated using png picture as background, in cross in following transverse direction
The regional scope of upward displayable content.
It should be noted that the emphasis paid close attention to herein be point nine figures size and how nine figure of non-dots shows content, therefore,
It can't excessively refer to spacing marking line and spacing marking line in transverse direction in longitudinal direction.

The color of each pixel on row is identical, then explanation, which carries out transverse compression to the transversal stretching region, not will lead to a little nine figure
Necessary information (will not influence Android system and transversal stretching is carried out to nine figures of point) is lost, it therefore, can be to the transversal stretching area
Domain carries out transverse compression, and the pixel reduce is redundancy.
Similarly, for putting any longitudinal extension region of nine figures, if in the longitudinal extension region, in a line
Each pixel color it is identical, then explanation to the longitudinal extension region carry out longitudinal compression not will lead to a little nine figures lose
Necessary information (will not influence Android system to point nine figures carry out longitudinal extension), therefore, can to the longitudinal extension region into
Row longitudinal compression, the pixel reduce are redundancy.
In order to make those skilled in the art more fully understand the technical solution in this specification embodiment, below in conjunction with this
