Embodiment
Below with the embodiment of DETAILED DESCRIPTION The present application.Should be noted that the embodiments described herein only is used to illustrate, be not limited to the application.
According to an embodiment of the invention based on the dividing method that covers the plate file, be to have adopted a picture that contains multiple key color to cover the plate file as one, every kind of key color has just been represented a zone, also has the picture that needs are cut apart simultaneously, this picture that need cut apart passes through and covers some computings of plate, just can be partitioned into several zones according to the shape of covering different colours segment on the plate.
Describe the method for cutting apart picture based on illiteracy plate file automatically of the present invention in detail below in conjunction with accompanying drawing.
See also Fig. 1 earlier, Fig. 1 illustrates of the present invention one exemplary illiteracy plate figure.Cover plate figure and can be divided into a plurality of different segments according to different colors.In the illiteracy plate figure that illustrates, for example, the size of covering plate figure is 400 pixel *, 400 pixels, wherein is divided into 4 altogether, and every has different colors respectively.Each segment is according to the order of upper left, upper right, lower-left, bottom right, and their color value is respectively RGB (0,255,0), RGB (255,0,0), RGB (0,0,255), RGB (0,255,255), that is, green, red, blue, light blue.
See also Fig. 2 below, Fig. 2 exemplarily illustrates the flow process according to the method for cutting apart picture automatically of the embodiment of the invention.
At first, read in one and cover the plate file.Cover the plate file and can be the art designing personnel in advance according to demand and the illiteracy plate picture of drawing, each segment that covers in the plate picture marks with different colors.In addition, the illiteracy plate file that various draftings are good also can be stored in the database in advance.For example, when needs are simply cut apart picture, just can adopt illiteracy plate as shown in Figure 1, wherein be divided into 4 segments, mark with different colors respectively.In other cases, if desired picture is carried out than complicated dividing, can certainly adopt other illiteracy plate not shown in the figures, for example 6,8,16,32,64 ..., and even polylith more.And, even for the identical illiteracy plate of figure number of blocks, the segmented shape of boundary also can be different between the different segments, and for example for the illiteracy plate that is divided into 4 segments shown in Figure 1, the convex-concave shape of its segment boundary, convex-concave quantity etc. can be carried out various suitable variations.
Covering reading in of plate file can be to carry out according to the illiteracy plate reading command of user's input.Be to store in advance in the database under the situation of the good illiteracy plate file of various draftings, the user can cover piece number and the shape that the plate reading command selects to cover segment in the plate by this, thereby can cut apart picture in the mode of oneself wishing.
Then, set up a mapping table, the index of table is a color, and the value of color correspondence is regional record data minX, minY, and maxX, maxY specifies as follows.At each segment, corresponding one group of numerical value respectively, this group records of values minX, minY, maxX, maxY promptly, has location of pixels minimum value and the maximal value on directions X and Y direction respectively in a kind of segment of color.
For example, can begin pixel is traveled through from the upper left corner of covering the plate picture, this is to travel through for the first time.From the upper left corner, the order of traversal can be from left to right, from top to bottom.In this order, for illiteracy plate file shown in Figure 1, can traverse green, red, blue, light blue these four kinds of colors successively.
When traversing first, the coordinate figure of this point can be composed to minX, minY, maxX, maxY is as its initial value.For example, the coordinate of supposing the green point at top left corner apex place in Fig. 1 is (0,400), and according to from left to right, during from top to bottom order traversal, this point is exactly first point that traverses.At this moment, just the coordinate figure that will put is composed to minX, and minY, maxX, maxY are as its initial value, that is, initial value is minX=0, minY=400, maxX=0, maxY=400.
Whenever traverse a new color, then in mapping table, add a new color record, color count value count adds one (in addition, according to another example of the present invention, also can store versicolor index in advance in this mapping table, when traversing a certain color, only need the regional record data storage is got final product to corresponding position); Simultaneously, by position and minX with current pixel, minY, maxX, maxY compares, and upgrades these regional values, thereby generates one group of new regional record data.
That is to say one group of minX is arranged at each key color, minY, maxX, the maxY data if traverse the color of this existence, just need be upgraded this group data according to the coordinate of current point, and method for updating is as follows:
If the coordinate x component＜minX of current point
The coordinate x component of the current point of minX=then;
If the coordinate x component＞maxX of current point
The coordinate x component of the current point of maxX=then;
If the coordinate y component＜minY of current point
The coordinate y component of the current point of minY=then;
If the coordinate y component＞maxY of current point
The coordinate y component of the current point of maxY=then.
Pixel to whole illiteracy plate picture travels through according to the method described above, simultaneously to regional record data minX, minY, maxX, maxY upgrades, and when full figure being finished once traversal, the axle in each zone corresponding with each color bounding box AABB that aligns just can be determined out.Particularly, the axle alignment bounding box AABB of each color segment is a rectangular area, and the border of this rectangular area is the regional record data minX according to pairing this color, minY, and maxX, maxY determines.
For example, for the green segment in the upper left corner among Fig. 1, its alignment bounding box AABB is included in all green pixels wherein; In addition, owing to have irregular convex-concave shape at the segment boundary, except green pixel, the axle alignment bounding box AABB of this green segment still includes other color pixel inevitably, and is for example red, blue and light blue.
The situation of the axle alignment bounding box AABB of other color segment and roughly the same above-mentioned is omitted its specific descriptions at this.
As mentioned above, at the axle alignment bounding box AABB of each color, except with this color of its correspondence, also comprise other color simultaneously inevitably.In order from the axle alignment bounding box of rectangle, to extract the concrete shape of each color segment,, to do transparent processing for other color except corresponding color among each alignment bounding box AABB so that picture to be split is cut apart.
For example, can define a keyColor variable, as the color of current AABB correspondence.When picture to be split is cut apart, get pixel one time at each AABB, the capture element is to need to get in the divided picture really, this picture size and shape are wanted and size and the shape of illiteracy plate figure are consistent, promptly, the outline of picture to be split should be able to overlap fully with the outline that covers plate figure, in other words, covers plate figure and can make to measure for picture to be split.For example, needing divided figure in the present embodiment also is 400 pixel *, 400 pixels, and its outline can overlap fully with the outline that covers plate figure, for example all is rectangle.
In this transparent processing, thereby picture to be split is cut apart for the concrete shape that extracts each color segment, also need once be traveled through, be i.e. traversal for the second time for the axle alignment bounding box AABB of each color segment.
In this travels through for the second time, because the outline of picture to be split can overlap fully with the outline that covers plate figure, therefore their coordinate positions in same coordinate system are consistent, that is, make picture to be split have identical coordinate with respective point among the illiteracy plate figure.For example, the coordinate of the green point at top left corner apex place is under the situation of (0,400) in covering plate figure, makes the coordinate of picture top left corner apex to be split also be (0,400), and similarly, the coordinate of all the other respective point is also consistent mutually.Herein, the coordinate of a certain position can with (i, j) expression, wherein, 0≤i≤400,0≤j≤400.
This travels through for the second time is that all colours for writing down in the mapping table after for the first time traversal is finished carries out successively.For every kind of color, on the axle alignment bounding box AABB of this color, carry out this and travel through for the second time, the result of the foundation traversal second time carries out pixel extraction to picture to be split simultaneously.Particularly, in traveling through for the second time, coordinate is (i in traversing illiteracy plate figure, during j) pixel, (i j) locates the color of pixel pairing color of bounding box (being keyColor) of aliging with this axle and compares will to cover coordinate among the plate figure, if cover coordinate (i among the plate figure, j) locate the color of pixel pairing color of this alignment bounding box just, then (i j) locates to take out the pixel of this picture to be split to the coordinate of the relevant position in picture to be split; Otherwise (i, j) locating color of pixel is not the pairing color of this alignment bounding box, then can not take out corresponding coordinate (i, the pixel of j) locating from this picture to be split if cover among the plate figure coordinate.Herein, at coordinate (i, j) pixel of locating to take out this picture to be split is meant, storing coordinate (i in a storage space (for example memory headroom etc.), j) locate the expressed various image informations of pixel, as color of pixel, tone, brightness etc., so that the expressed image information of this pixel is carried out complete reproduction.
For example, carry out this when traveling through for the second time for the axle alignment bounding box AABB of Fig. 1 medium green chromatic graph piece, keycolor is green.If the coordinate that in covering plate figure, traverses (i, the pixel color of j) locating is for green, and then (i j) locates to take out the pixel of this picture to be split to the corresponding coordinate in picture to be split; On the contrary, if (i, the pixel color of j) locating is not green to the coordinate that traverses in covering plate figure, then can not take out corresponding coordinate (i, the pixel of j) locating from this picture to be split.
For example, this time traversal can be corresponding to following program statement:
For a kind of color, after this time the pixel traversal is finished, the pixel of the picture to be split that can store in storage space takes out as stated above (promptly, store the expressed various image informations of this pixel), the picture that splits has just been formed in the set of these pixels, and the pixel region of the picture that the set of these locations of pixels coordinates just is divided into.For example, after the axle alignment bounding box AABB to Fig. 1 medium green chromatic graph piece has carried out traveling through for the second time, corresponding to all green pixels in this alignment bounding box, corresponding coordinate takes out pixel from picture to be split, then formed the collection of pixels with the corresponding picture to be split of shape of this green segment, this collection of pixels has also just been formed and the corresponding picture of cutting apart of this green segment.
After the first kind of color that writes down in as mentioned above according to mapping table carried out cutting apart to picture to be split, also need according to other color that writes down in the mapping table this picture to be split to be cut apart successively, until finishing according to last a kind of color to till the cutting apart of this picture to be split.Promptly, the axle alignment bounding box to first kind of color carry out traveling through the second time and be partitioned into cut apart picture accordingly after, successively the axle alignment bounding box of other color is carried out traveling through second time again, and from picture to be split, take out respective pixel, thereby according to other color this picture to be split is cut apart successively, until according to last a kind of color segment till.
For example, for illiteracy plate shown in Figure 1, after picture to be split having been carried out cutting apart, also need according to the shape of red segment, blue segment, light blue segment this picture to be split to be cut apart successively according to the shape of green segment.After all finishing the cutting apart of four kinds of colors of all that in according to mapping table, write down, just this picture to be split can be divided into four pictures, these four shapes of cutting apart picture are corresponding with green, redness, blueness, light blue segment among Fig. 1 respectively, are used for doing four segments making picture arrangement game thereby also just formed according to illiteracy plate shown in Figure 1.
Referring to Fig. 3 and Fig. 4, it illustrates uses the example that method of the present invention is cut apart picture.Original picture to be split as shown in Figure 3, it can be any width of cloth picture of being specified or being chosen by the user; First file that goes out with the illiteracy plate file division of Fig. 1 as shown in Figure 4, promptly with the corresponding divided file of green segment.Certainly, along with the difference of the illiteracy plate file that is obtained, quantity and the shape of cutting apart picture all can respective change.
