Abstract
The invention relates to an image display method and apparatus. The method comprises the steps of allocating a bitmap according to a fixed size by a slave system, wherein the size of the bitmap is a multiple of a least common multiple of the sizes of various images in the system; dividing the bitmap into clusters same in size according to the least common multiple, wherein the same cluster contains a plurality of images same in size, and a part used for image display in each cluster is called a slice; determining a corresponding slice used for displaying an image needed to be displayed according to the size of the image needed to be displayed; decoding the image needed to be displayed by utilizing a created bitmap used for image decoding; drawing the decoded image to the corresponding slice; and displaying an effective region in the drawn corresponding slice, wherein the effective region contains the image needed to be displayed. The frequency of allocating a big object from a Java stack can be greatly reduced, so that the junk collection frequency is reduced and the responsibility of a user interface is improved when more images can be displayed.

Family is experienced.
Fig. 1 is the flow chart of the method for displaying image according to the disclosure one exemplary embodiment, the method include with
Lower step S110, S120, S130, S140, S150 and S160：
In step s 110, from system according to fixed size assignment bit map, wherein, the size of bitmap is various in system
The multiple of the least common multiple of the size of image.
In one embodiment, when system (for example, android system) assignment bit map, according to fixed size distribution, should
The size of bitmap is the size at double of least common multiple size, it is possible to it is called page (Page).
In the step s 120, bitmap is divided into equal-sized bunch (Cluster) according to least common multiple, wherein, with
One bunch accommodates the identical image of multiple size, and in each bunch, the part for showing image is referred to as cutting into slices (Slice).
In one embodiment, according to least common multiple size, bitmap being divided into one piece one piece, each block size is all
Identical, it is referred to as bunch.In one embodiment, when being used for showing, can accommodate multiple image in each bunch, each image accounts for
According to size be all identical, bunch size be the multiple of size of image, each is for showing that the part of image is referred to as cutting
Piece.In one embodiment, different bunches, slice size can be different.Different size of section can be used for display difference
The image of size.
In step s 130, the image that the size determination of the image according to a width needs display shows for showing needs
Respective slice.
Fig. 2 shows the flow chart of step S130 in Fig. 1.As in figure 2 it is shown, step S130 include step S210 and
S220.
In step S210, the size of the image of display is needed to calculate for showing the image that needs show according to a width
Required section.
In step S220, search belonging to required section bunch.
In one embodiment, the size needing the image of display according to a width calculates for showing the figure that needs show
The required section of picture, i.e. determine the size of section of display image, and belonging to this level of section bunch, in order to profit
With the section display image in this bunch.
In one embodiment, step S130 also includes：Do not find belonging to required section bunch in the case of, point
Joining one new bunch, wherein, new bunch has the respective slice for showing image that needs show.That is, suit the requirements the figure showing
The section of the size of picture and affiliated bunch do not exist, therefore, by distribution one new bunch, enabling utilize in this new bunch
Section display image.
In one embodiment, step S130 also includes：In the case of cannot distributing one new bunch, distribute a new position
Figure, wherein, new bitmap have belonging to described respective slice bunch.That is, existing bitmap does not have space be allocated new bunch, therefore,
By one new bitmap of distribution, in new bitmap, distribute one new bunch, enabling utilize cutting in new bunch in this new bitmap
Piece shows image.
In one embodiment, step S130 also includes：In the case that the number of bitmap reaches the upper limit, eliminate one and work as
Before do not show image bunch, and distribute one new bunch, wherein, new bunch has for showing cutting accordingly of image that needs show
Piece.That is, in the case of not having space to distribute new bitmap, need to eliminate one be currently not used by bunch, and on this basis
Distribute one new bunch, enabling utilize the section display image in this new bunch.
In one embodiment, it is necessary to during display piece image, calculate, according to image size, the section that use, look into
Look for respective slice bunch, if it does not exist, then distribution one new bunch, if new bunch cannot be assigned to, then distribute a new page.When
The number of page is when having arrived at the upper limit, then be not currently displayed bunch carrying out of image according to certain expired algorithms selection of caching
Eliminate, and notify UI picture failure therein.
In step S140, the bitmap being created for image decoding is utilized to be decoded the image needing display.
In one embodiment, when decoding image, a section cannot be used directly for image decoding.System is (for example,
Android) support to reuse bitmap decoding, if the internal memory that the memory size that bitmap takies should take more than image decoding
Size, system can be decoded to use this bitmap.Therefore, it can create a bitmap being specifically designed to decoding.Consider
To precondition：The image size of one application display is fixed several exactly, after this bitmap creates several times, and Jiu Huiyi
Straight reuse is gone down, so, will not create frequently and discharge.Furthermore, it is also possible to when creating this bitmap for the first time, just wound
Build the bitmap of maximum demand.
In step S150, decoded image is signed in respective slice.
In step S160, showing the effective coverage in the respective slice finished, wherein, effective coverage comprises needs and shows
The image showing.
In one embodiment, step S160 includes：When system is android system, the respective slice that will be finished
In effective coverage sign on the painting canvas of android system.
According to the method for displaying image of disclosure embodiment, by from system according to fixed size assignment bit map, wherein, position
The size of figure is the multiple of the least common multiple of the size of the various images in system；Bitmap is divided into according to least common multiple
Equal-sized bunch, wherein, same bunch accommodates the identical image of multiple size, for showing the part of image in each bunch
It is referred to as section；The respective slice of the image that the size determination of the image according to a width needs display shows for showing needs；
The bitmap being created for image decoding is utilized to be decoded the image needing display；Decoded image is signed in accordingly
Section；Effective coverage in the respective slice that display is finished, wherein, effective coverage comprises the image that needs show, Neng Gou great
Amplitude reduction is from the frequency of the big object of Java heap distribution, thus reduces the frequency of refuse collection, can show more image
While, improve the response of user interface.And, on the premise of ensureing the response of user interface, can be user
Interface display image as much as possible, it is to avoid the frequent loading of image in navigation process, improves efficiency, improves user's body
Test.
