Fig. 2 is a kind of method flow diagram of display image according to an exemplary embodiment, the execution master of this method Body can be terminal, as shown in Fig. 2 comprising the following steps.
In step 201, terminal is obtained in the second display interface during the first display interface shows the first image Image subdata of each pixel in the second image, second display interface for first display interface prevpage or The display interface of person's the next page.
In the embodiment of the present disclosure, during user is by terminal image browsing, for example, user's using terminal browses shopping In website during the thumbnail of multiple commodity, terminal can first obtain the previous of terminal screen in the image of display terminal screen The view data of page or the next page image, when being easy to the subsequent user to slide image list, terminal directly according to the prevpage or The data of person's the next page image, the image of the prevpage or the display interface of the next page is quickly included in terminal screen.
Wherein, the first display interface be terminal screen, the second display interface for first display interface prevpage or There can be multiple first images in the display interface of the next page, the first display interface, the first image is appointed for the first display interface There can be multiple second images in one image, the second display interface, the second image is the first display interface prevpage or latter Any image in the display interface of page.The viewing area of each first image in first display interface and the second display interface In the second image display area can be with identical.
This step can be realized by following steps 2011-2013.
In step 2011, terminal obtains the first view data of second image from server, according to the first image Picture size, the picture size of second image is adjusted to the picture size.
In this step, terminal pre-sets the picture size of the first image, and the picture size of first image is terminal First image included into picture size in the first display interface, the server storage image identification and image of each image The corresponding relation of data.
Wherein, the step of terminal pre-sets the picture size of the first image can be:Terminal obtains pre-set dimension, according to The picture size of first image is set to pre-set dimension by the pre-set dimension, terminal.Wherein, the pre-set dimension can be to be shown Actual size of the image in terminal screen, or, when terminal shows the thumbnail of multiple images in terminal screen, this is pre- If size can also be the size of the thumbnail.
Wherein, the pre-set dimension can need to set and change according to user, and the embodiment of the present disclosure does not make specific limit to this It is fixed.
Therefore, step 2011 can be:Terminal obtains the image identification of each second image in second display interface, root According to the image identification of each second image, from the image identification of server storage and the corresponding relation of view data, obtain every Corresponding first view data of image identification of individual second image, then, terminal is according to the picture size of first image, by The picture size of two images is adjusted to the picture size of the first image.
Wherein, the picture size of the second image is adjusted to the first image by terminal according to the picture size of first image The process of picture size can be:If the picture size of first image is more than the picture size of the second image, terminal-pair Second image is amplified processing, so that the picture size of the second image to be stretched to the picture size of the first image;If The picture size of first image is less than the picture size of the second image, and terminal-pair second image carries out diminution processing, or Shear treatment, so that the picture size of second image to be cut to the picture size of the first image;If first image Picture size is the picture size of the second image, and the picture size of terminal-pair second image is not processed.
In step 2012, terminal determines the second picture number of second image after adjustment from first view data According to.
In this step, because the picture size of the second image is adjusted to the picture size of the first image, the second figure by terminal The picture size of picture is after scaling, and the first view data of the second image also changes therewith, therefore, and terminal also needs first to determine to adjust Second view data of the second image after whole.
The step of terminal determines the second view data of second image after adjustment from first view data can be with For:
Terminal determines the second figure after adjustment according to the picture size of the second image after adjustment from the first view data Second view data of picture;Or,
Terminal determines the scaling of the second image, and the first view data of the second image is carried out according to the scaling Scaling processing, the second view data of the second image after being adjusted.
For example, the original picture size of the second image is 1280*720, the picture size of the second image after adjustment is 405*720, then terminal 1280*720 view data is cut into the view data of 405*720 (typically retaining center section).
In step 2013, terminal-pair second view data is decoded, and obtains each pixel in second image In image subdata.
In this step, the second view data of the second image after terminal-pair adjustment is decoded, and obtains each pixel The image subdata in the second image after the adjustment, i.e. the corresponding each pixel of the second image in the second display interface Image subdata.
In a kind of possible design that the embodiment of the present disclosure is provided, terminal can also obtain the second image from server After first view data, first the first view data to second image is decoded, then adjusts the picture size of the second image, Now, the process can be:Terminal obtains the first view data of the second image from server;Terminal-pair second image First view data is decoded, and obtains the image subdata of the second image;Terminal is according to the picture size of the first image, by this The picture size of second image is adjusted to the picture size of first image;Terminal determines the figure in second image after adjustment As subdata, image subdata of each pixel in second image is obtained.
In step 202., terminal replaces image subdata of each pixel in the first image in spatial cache For the image subdata in the second image.
In this step, terminal can directly replace image subdata of each pixel in the first image in spatial cache The image subdata in the second image is changed to, without opening up spatial cache again for the image subdata of the second image, so that Save the spatial cache taken during the second image of terminal buffers.
This step can be realized by following steps 2021-2022.
In step 2021, terminal is in the spatial cache, it is determined that the corresponding spatial cache of each pixel.
It should be noted that terminal is obtained after the image subdata in the second image of each pixel after the adjustment, also Image subdata in second image need to be stored in spatial cache, when being easy to the terminal to show second image, directly from Image subdata of each pixel in the second image is obtained in spatial cache, so that quick include the second image in terminal In screen.
In this step, the corresponding spatial cache of each pixel is used to store the corresponding image subdata of each pixel, Because the picture size of each second image is adjusted to the picture size of the first image, therefore, every page display interface by terminal The picture size of middle image be it is identical, therefore, the picture that the pixel and each second image that each first image includes include Vegetarian refreshments quantity all same, i.e. the spatial cache size all same that each first image or the second image take.
The corresponding relation of the store path of the mark of each pixel and the pixel in terminal storage display interface, because This, in this step, the step of terminal determines each pixel corresponding spatial cache can be:Terminal is according to each pixel Mark, from the corresponding relation of the position of each pixel and store path, it is determined that the corresponding store path of each pixel;Eventually The corresponding spatial cache of the store path is defined as the corresponding spatial cache of the pixel by end.
Wherein, the mark of pixel can be position coordinates of the pixel in terminal screen, or pixel Numbering, the embodiment of the present disclosure is not especially limited to this.Store path can need to set and change according to user, and the disclosure is real Example is applied to be not especially limited store path.The store path can be the name of the memory headroom or the spatial cache newly opened up Title, location index etc..
In step 2022, for each pixel, terminal is by the corresponding spatial cache of the pixel, the pixel Image subdata in first image replaces with the image subdata in second image.
In the embodiment of the present disclosure, terminal stores image of the first image in the corresponding spatial cache of each pixel Data, in order to reduce the spatial cache of storage image subdata occupancy, terminal can be directly by each pixel in the first image In the spatial cache that currently takes of image subdata, be defined as the slow of image subdata of each pixel in the second image Space is deposited so that terminal opens up spatial cache again without the image subdata again for the second image, so that it is empty to save caching Between.
This step can be:Terminal obtains image subdata of each pixel in the second image, according to each pixel Image subdata in the corresponding spatial cache of point, the first image that the spatial cache is stored replaces with the pixel second Image subdata in image.
After the image subdata of each second image of terminal storage, each second image of storage and second image are also needed The corresponding store path of image subdata corresponding relation, the mark of each pixel and the second image due to terminal storage Image identification corresponding relation.Therefore, the process can be:Terminal is according to the image identification of each second image, from pixel Mark and the second image image identification corresponding relation in, determine the corresponding pixel of image identification of second image Mark;Terminal from the mark of pixel and the corresponding relation of store path, determines the pixel according to the mark of each pixel The corresponding store path of point;Terminal obtains the corresponding store path of each pixel that each second image includes, every according to this The corresponding store path of individual pixel determines the corresponding store path of each second image;The image mark of the image of terminal storage second Know the corresponding relation with store path.
It should be noted that the spatial cache is the spatial cache that data are preserved using binary system.Because terminal uses two System preserves the image subdata of the first image or the image subdata of the second image, reduces the image subdata of the first image Or second image the spatial cache that need to take of image subdata.
Wherein, the spatial cache can be Blob Cache (document caching), because the Blob Cache can use two System preserves data, also, terminal is during display image, during due to display every time, can be by the of each pixel The image subdata of one image replaces with the image subdata of the second image, therefore, and it is slow that terminal storage image subdata takes Deposit space smaller;Terminal will not be cleared up the view data stored in the Blob Cache by GC modes, so that Terminal is not in interim card when sliding the first image or the second image that show every page.
