That is nine palace regions.
The memory of textures to be compressed is parsed, parses library, such as PNG format figure using the corresponding picture of picture format
Piece is parsed using the library LIBPNG, corresponds to RGB and transparence information value by parsing each pixel.To textures to be compressed
Memory scans line by line, if pixel value is equal with perimeter data at nine palace position of textures, then illustrates this position combinable week
Side pixel merges memory textures information, and records nine new palace positions.
As shown in Figure 5, will be from the 24th row of memory textures array, the 104th row lateral probe movement, the 24th arranges, and the 104th column are swept up and down
It retouches, the position of identical numerical value gradually merges.Until neighboring pixel cannot be remerged, new textures output is modified into original nine palace
Information.
By above step, textures are finally gone out into figure original size 128*128 pixel from the fine arts, have been compressed to 30*30 picture
Element, as shown in fig. 6, the inner width of target textures and Nei Gao are compressed to the pixel region of 2*3.
Target textures are modified to information shown in table 2:
| Originate x | Originate y | Inner width | Interior height | Beam overall | It is total high |
| 14 | 13 | 2 | 3 | 30 | 30 |
From the above, maximized to reduce nine palace pixel coverages by nine palace textures of script, so that it is entire to reach reduction
The purpose of textures size.
In addition, practical fine arts textures are mostly not fully equal in nine palace pixel values, each channel RGBA may differ several
A pixel, however human eye is generally difficult to discover for the change within several pixel differences, therefore, scanning algorithm among the above can be with
It suitably softens terms, by modifying pixel difference range, more nine palaces region out can be compressed, reach bigger compression effectiveness.
It is not the textures in nine palaces originally for GUI design, nine palaces compression can also be carried out to it and generates best nine palaces letter
Breath.
1) textures are read and enters memory, as shown in fig. 7, being one for showing the textures of bubble, the fine arts, which go out primitive, to be begun not having
There are nine palace information, textures occupancy is huge, and original size is 286*132 pixel.
2) textures information is read line by line, and the equal region of maximum pixel is found in textures, rejects equal region,
The starting for rejecting region is nine palace starting points, rejects the range size that range size is nine palaces.
3) textures after output reduction, export nine palace information, as shown in Figure 8.
The information of final target textures is as shown in table 3:
| Originate x | Originate y | Inner width | Interior height | Beam overall | It is total high |
| 4 | 5 | 3 | 3 | 132 | 24 |
By above step, JiuGongTu can be converted by textures most of in project, to greatest extent by textures
It repeats pixel to reject, reduces textures occupied space.
Fig. 9 is some original textures in this example, and Figure 10 is the textures after compressing in the present embodiment.It follows that
By above step, it is original most effective that picture can be retained so that fine arts textures are found out same or similar pixel under line and are rejected
Information achievees the purpose that effectively to reduce redundancy textures resource.Meanwhile this scheme also facilitates extension extension mono- to put up possibility in figure
Nine palace region of duplicate removal is cut there are multiple, duplicate region total number can be cut and be merged, textures be reassembled into new nonstandard
Quasi- rectangle textures record each small corresponding location of pixels in nine palace regions and size.Then, in rendering, read textures
It is all can nine palace regions data information, address single nine palaces textures corresponding position.Herein optimize after, whole textures by change more
Small, textures, which measure, greatly to be compressed, and is obtained highest pixel and is utilized.
