Referring to Fig. 2, be the second embodiment process flow diagram of the display packing of the application's background picture:
Step 201: the decoding unit picture obtains decoded pixel data.
Before picture is shown, must decode to it earlier, decoded results is some data bitmaps, these data bitmaps are at the just corresponding internal memory of computer-internal.With the ARGB8888 color format is example, the information of a pixel need be described with four bytes, be respectively alpha (transparent position), red (redness), green (green), blue (blueness), formula below the shared memory size of the decoded view data of picture satisfies: the height of the wide * picture of the shared memory size=picture of the decoded data * needed byte number of each pixel, for example: to one wide be 25, height is 35 picture, under the ARGB8888 color format, the shared memory size of decoded view data is: 25 * 35 * 4=3500 byte.
Step 202: the target viewing area of background picture is divided into some unit areas according to the size of unit picture.
Concrete, the width parameter of acquiring unit picture and height parameter, and the width parameter and the height parameter of the target viewing area of background picture, calculate first quotient of the width parameter of target viewing area, and the height parameter of target viewing area is divided by second quotient of the height parameter of unit picture divided by the width parameter of unit picture; The target viewing area is divided according to first quotient in the horizontal direction, and in the vertical direction is divided according to second quotient, generates the consistent unit area of product quantity with first quotient and second quotient.
As shown in Figure 3A, be shown to the synoptic diagram of target viewing area for a kind of unit picture.Wherein, suppose the wide img_w of being of picture, the height of picture is img_h, and the wide of screen is screen_w, and the height of screen is screen_h, and the wide of target viewing area is w, and the height of target viewing area is h.Supposing need be with the unit picture by the point (x of original size from the target viewing area, y) locate beginning, tiling is presented in the target viewing area, then as shown in Figure 3A, supposes that img_w and img_h are 10px, w is 30px, h is 20px, then needs three unit pictures of tile horizontally in the target viewing area, two unit pictures of tile vertical, totally six unit pictures, promptly the target viewing area can be divided into six unit areas.Wherein, the initial point of supposing screen is the point in the upper left corner, is to the right x axle positive dirction, is downwards y axle positive dirction.Then each pixel can correspond on the respective point in the screen in the unit picture, with from point (x, y) Ping Pu first unit picture is an example, its corresponding relation is as shown in table 1 below:
Table 1
Step 203: each unit area laterally is divided into the several rows subregion.
Concrete, the height parameter of acquiring unit picture, the value of height parameter is consistent with the pixel number of unit picture on short transverse, and each unit area laterally is divided into the capable subregion consistent with the pixel number.
Referring to Fig. 3 B, for row unit area, first in the target viewing area among Fig. 3 A being divided into the synoptic diagram of capable subregion.Wherein, still the img_w and the img_h that suppose the unit picture are 10px, then the wide and height of corresponding each unit area also is 10px, according to the unit area height is 10px, the unit area laterally is divided into 10 capable subregions, and shown in Fig. 3 B, three unit areas in the first row unit area laterally are being divided into ten capable subregions, it is consistent with the first row unit area that the row subregion is divided in the second row unit area, no longer gives unnecessary details by diagram at this.
Step 204:, the capable pixel data of the decoded N of unit picture is filled into the capable subregion of N of first unit area in the first row unit area for the capable subregion of N of row unit area, first in some unit areas.
In the realization pixel data tiles target viewing area process, the tiling interface of a special use can externally be provided, the width and the height of target viewing area are passed to this tiling interface as parameter, this interface can be as follows: image_display_tiled (void*img, int x, int y, int w, int h);
Wherein, img represents the handle of the picture of actual needs demonstration, can obtain the width and the height of flat picture by this handle; X is the horizontal ordinate of the upper left corner, target viewing area on screen, and y is the ordinate of the upper left corner, target viewing area on screen; W is the wide of target viewing area, and h is the height of target viewing area.
Step 205: the capable pixel data of N increased progressively to duplicate according to two inferior power be filled in the capable subregion of N that removes the residue unit area in first module zone in the first row unit area, the span of N is the number of the 1 capable subregion of dividing to each unit area.
By as can be known aforementioned, the img_w and the img_h of the decoded pixel data of unit picture are 10px, and therefore decoded pixel data has ten row pixel datas.Shown in Fig. 3 C, wherein show the first row subregion of the first row unit area, target viewing area, in order to clearly demonstrate the process of the embodiment of the present application filler pixels data, the width of target viewing area shown in Fig. 3 C is 200px, therefore comprise 20 unit areas in its first row unit area, therefore the first row subregion comprises 20 capable subregions altogether.Among Fig. 3 C, laterally expression row subregion vertically represents to fill number of times.Below in conjunction with Fig. 3 C, describe the first row subregion carried out the process that increasing progressively of pixel data duplicated filling according to two inferior power:
Among Fig. 3 C, the target viewing area is divided into 20 equal-sized capable subregions by image_w, it is numbered from 1 to 20 respectively.Duplicate for the 1st time, the first row pixel data of the decoded data of unit picture is copied to be numbered in 1 the capable subregion; Duplicate for the 2nd time, copy to and be numbered in 2 the capable subregion being numbered pixel data in 1 the capable subregion; Duplicate for the 3rd time, copy to and be numbered in 3 and 4 the capable subregion being numbered pixel data in 1 and 2 the capable subregion; The 4th is duplicated, and copies to and is numbered in 5 to 8 the capable subregion being numbered pixel data in 1 to 4 the capable subregion; The 5th is duplicated, and copies to and is numbered in 9 to 16 the capable subregion being numbered pixel data in 1 to 8 the capable subregion; Duplicate for the 6th time, owing to only remain four capable subregions, therefore only needs will be numbered pixel data in 1 to 4 the capable subregion and copy to be numbered in 17 to 20 the capable subregion and get final product.The capable subregion that black is filled among Fig. 3 C is represented the pixel data of filling each time, hence one can see that, duplicate for preceding 5 times, all be that the pixel data in the first row subregion is enlarged two times, promptly increase progressively filling according to two inferior power, duplicate for the last time, because two times of 16 capable subregions that residue row subregion has once been filled before the deficiency, therefore directly go the quantity of subregion and carry out duplicating of pixel data by residue.
By aforementioned description as can be known, the reproduction process of the pixel data of first row in the subregion number of times that needs invoke memory to duplicate interface is
Being the wide merchant of the wide of target viewing area and unit picture, is to take the logarithm at the end with 2, rounds up again, adds one at last, wherein symbol
Expression rounds up.
In like manner, also fill, finish the filling of the first row unit area with this according to the mode that the aforementioned first row subregion is described for other the nine row subregion in the first row unit area.Hence one can see that, and the internal memory that finishing the picture tiling in the first row unit area needs duplicates the interface interchange number of times and is:
Be that each row subregion invoke memory duplicates the number of times of interface and the product of the capable subregion number that the first row unit area is divided, the unit picture is according to the division of the capable subregion of unit picture element after will decoding in the present embodiment, and therefore the data of row subregion are consistent with the value of the image_h of unit picture.
Step 206: the capable subregion of N in other each row unit area of removing the first row unit area in some unit areas, carry out full line according to the pixel data of having filled in the capable unit area of N in the first row unit area and duplicate.
After the tiling of unit picture, duplicating of vertical direction data based on first pixel data of arranging after duplicating, directly carried out full line and duplicated in finishing the first row unit area.
With the second row unit area is example, the population size of the unit picture that it is filled is all the same with the first seniority among brothers and sisters subregion, therefore its capable subregion quantity of dividing is consistent with the first row unit area, promptly also be divided into ten capable subregions, carrying out full line when duplicating, pixel data full line in the first row subregion in the first row unit area is copied in the second first row subregion of arranging in the unit area, pixel data full line in the second row subregion in the first row unit area is copied in the second second row subregion of arranging in the unit area, the rest may be inferred, in the tenth row subregion that the pixel data full line in the tenth row subregion in the first row unit area is copied in the second row unit area.
In like manner, for each the row unit area in the ten row unit areas, the 3rd row unit area to the, all carry out the pixel data filling, thereby finish the demonstration of background picture according to above-mentioned full line copy mode.
Hence one can see that, except that the first row unit area, each row subregion all is to carry out the entire row of pixels data to duplicate in other row unit area, so other row unit area finishes that to fill the number of times need invoke memory to duplicate interface be (h ÷ image_h-1) * image_h=h-image_h in the target viewing area.To sum up, carrying out the total degree that background picture shows that required invoke memory duplicates interface by the embodiment of the present application is
As seen from the above-described embodiment, owing to need not each unit picture is tiled according to its row pixel, duplicate but increase progressively increasing progressively of pixel data according to two inferior power in the horizontal direction, vertical direction carries out duplicating of pixel data according to full line, therefore reduce calling interface and carried out the number of times that pixel data is filled, calculated amount reduces, and has improved the display speed of background picture thus.Still with unit picture width with highly be 10px, the target viewing area of tiling width and highly being 200px is an example, the number of times that adopts the prior art scheme to need invoke memory to duplicate interface is w * h ÷ image w=200 * 200 ÷ 10=4000 time, and the internal memory that the employing present embodiment need call duplicates the interface number of times and is
Inferior, hence one can see that, and the application's background picture shows that embodiment can greatly reduce the call number of internal memory being duplicated interface, has improved the display speed of background picture.
