At present, the collapse rate of an application program after the application program is operated online is a critical index for measuring the performance of the application program, and at this time, in order to improve the operation performance of the application program, an abnormal collapse phenomenon of the application program needs to be reduced as much as possible, and the operating memory overflow is a main cause of the collapse of the application program, and the operating memory overflow is mainly caused by that the operating memory occupied by image display in the application program is too large. Therefore, the embodiment of the present invention mainly aims at the memory occupied by the displayed image in the application program causing the memory overflow, and determines the resolution threshold value that the corresponding image needs to meet through the image display area on the screen after the sliding operation, that is, the memory occupied size that the image should meet when displaying, so that the image larger than the resolution threshold value is reduced and then displayed in the image display area, thereby reducing the pixel information contained in the displayed image in the operation process, reducing the operation memory occupied by the image display, and further improving the image display efficiency and the operation performance of the application program.
Example one
Fig. 1 is a flowchart of an image display method according to an embodiment of the present invention, which can be applied to any application program with image display requirements. The technical scheme of the embodiment of the invention is suitable for reducing the running crash of the application program caused by memory overflow in the running process. The image display method provided by this embodiment may be executed by the image display apparatus provided by the embodiment of the present invention, the apparatus may be implemented by software and/or hardware, and the apparatus is integrated into a device for executing the method, where the device may be an intelligent terminal such as a smart phone, a tablet computer, and a notebook computer, which is configured with an application program having an image display function.
Specifically, referring to fig. 1, the method may include the steps of:
s110, acquiring operation information on the screen.
The method and the device mainly reduce the phenomenon of collapse of the application program by reducing the memory occupation amount of the image display in the running process of the application program, wherein the screen refers to a screen of the terminal device configured by the application program; the sliding operation information is an image request that a user executes a certain sliding operation in a display interface of an application program so that the application program needs to display a new image at a set position currently, and is used for indicating that the application program needs to acquire the new image for displaying. Specifically, the sliding operation information may include a sliding distance and a sliding direction corresponding to the current sliding operation, and a set position area capable of displaying corresponding image information displayed on the screen by the application before the sliding operation.
Specifically, in the running process of the application program, when optimizing the running memory occupied by the image display, the application program first needs to acquire the image to be displayed correspondingly, at this time, the application program is instructed to acquire the corresponding image to be displayed by executing a certain sliding operation or clicking operation in the display screen of the application program through the user, at this time, the application program can acquire the operation information generated by the user executing the corresponding operation on the screen, and if the sliding operation is executed, the specific sliding distance, the sliding direction of the sliding and the set position area capable of displaying the corresponding image information, which is displayed on the screen before the sliding operation, can be obtained.
And S120, acquiring a corresponding image according to the image display area on the operated screen.
The image display area is a display frame which is preset during development of the application program and can display corresponding images, and different image display areas correspond to images with different contents, such as various video picture display areas which can display different video information in a display interface of a video player.
Optionally, after the operation information on the screen is obtained, the embodiment may determine, according to each image display area displaying the corresponding image information displayed on the screen before the operation and the operation information corresponding to the operation, such as the sliding distance and the sliding direction, the image display area displaying the corresponding image information on the screen after the operation, and obtain, according to the image display area on the screen after the operation, the image corresponding to each image display area from the background server, so as to perform corresponding display.
Wherein, the image in the embodiment is a bitmap image; specifically, a Bitmap (Bitmap) is an image composed of a plurality of pixels and containing overall display information of each pixel; pixels are the smallest units of information in a bitmap, each pixel having a particular location and color value; information of each pixel in the image, such as the position of the pixel on the screen, the color of the pixel, and the like, is recorded in the bitmap in the order from left to right, top to bottom.
Optionally, in this embodiment, the corresponding image may be obtained by sending an image downloading request to the background server. For example, in this embodiment, when obtaining information of a sliding operation performed by a user on a screen, it may be determined that the application program currently needs to acquire a corresponding image for an image display area that newly appears on the screen after the sliding operation to display, at this time, the image download request is instruction information for instructing a background server to feed back the corresponding image for the image display area on the screen after the sliding operation, and the image download request may include an area identifier of each image display area on the screen after the sliding operation, where the area identifier is flag information that can uniquely indicate identity information of a certain image display area in the application program. When the sliding operation information on the screen is acquired, according to each image display area which is displayed on the screen before the sliding operation and used for displaying the corresponding image information, and the sliding distance and the sliding direction corresponding to the sliding operation, each image display area which is displayed on the screen after the sliding operation and currently needs to display the corresponding image information is determined, and according to the image display area on the screen after the sliding operation, a corresponding image downloading request is generated, wherein the image downloading request comprises an area identifier of each image display area on the screen after the sliding operation, and simultaneously, the image downloading request corresponding to the sliding operation is sent to the background server, and the background server determines a matched image for each image display area according to the area identifier of each image display area and feeds the matched image back to the application program; at this time, the application program can acquire the corresponding image determined by the background server for the image display area on the screen after the sliding operation according to the image downloading request, and then correspondingly display in each image display area.
And S130, if the resolution of the image is greater than the resolution threshold corresponding to the image display area, displaying the reduced image in the image display area.
And the resolution of the reduced image is less than or equal to the resolution threshold corresponding to the image display area. Specifically, when the images are displayed on the screen, a certain running memory of the application program is occupied, corresponding pixel information is recorded for each pixel included in each image, and at the moment, the running memory occupied by the images is determined by the size of the pixel information included in the images, so that in order to prevent the application program from collapsing in the running process, corresponding memory occupation thresholds can be set for each image display area respectively, so that the memory occupation of each image can be lower than the corresponding memory occupation threshold when the images are displayed, and the situation that the application program collapses due to the memory occupation of the image display is reduced. Specifically, in the embodiment, the memory occupation during image display mainly comes from the size of the pixel information included in the image, and the size of the pixel information of the image is represented by the size of the resolution of the image, and the higher the resolution of the image is, the more pixels in the unit length of the image are described, the larger the pixel information is included at this time, so that the memory occupation size is correspondingly represented by the resolution in the embodiment. At this time, in this embodiment, a corresponding resolution threshold is set for each image display area in the application program to indicate an upper limit value of a resolution that can be achieved by an image allowed to be displayed in the image display area, so that memory usage of image display in the running process of the application program is correspondingly reduced, and a phenomenon that the application program collapses during running is reduced.
Specifically, in order to determine whether an image displayed in an image display area satisfies a resolution threshold set in the image display area, in this embodiment, when a corresponding image is acquired according to the image display area on the screen after the sliding operation, the resolution of each acquired image needs to be determined first, and at this time, if the resolution of a certain image is greater than the resolution threshold set in the image display area corresponding to the certain image, it indicates that the resolution of the image is larger and the pixels included are more, so that the operating memory occupied by the pixel information of the image in the operating process of the application program is larger, which is likely to cause the application program to crash, therefore, the resolution of the image needs to be reduced correspondingly according to the resolution threshold corresponding to the image display area, that is, the pixels included in the image are reduced, so that the corresponding pixel information is reduced correspondingly, until the resolution of the reduced image is less than or equal to the resolution threshold corresponding to the image display area, the reduced image is displayed in the image display area, that is, the image finally displayed in the image display area can meet the resolution threshold set in the image display area, so that the memory occupation during image display is reduced, and the phenomenon that the application program is collapsed during operation is reduced.
According to the technical scheme provided by the embodiment, the resolution threshold value which needs to be met by the corresponding image is determined through the image display area on the operated screen, and the image with the resolution ratio larger than the resolution threshold value is reduced and then displayed in the image display area, so that the resolution ratio of the reduced image meets the requirement of the resolution threshold value, the pixel information contained in the displayed image in the running process is reduced, the running memory occupied by image display is reduced, the problem that the application program is easy to collapse due to the fact that the memory is excessively occupied in the running process is solved, and the image display efficiency and the running performance of the application program are improved.
Example two
Fig. 2A is a flowchart of an image display method according to a second embodiment of the present invention, and fig. 2B is a schematic diagram of an image display process according to the second embodiment of the present invention. The embodiment is optimized on the basis of the embodiment. Specifically, as shown in fig. 2B, the present embodiment explains in detail a specific display process of an image that needs to be displayed in a corresponding image display area and is acquired by an application program during the running process.
Optionally, as shown in fig. 2A, the present embodiment may include the following steps:
s210, acquiring operation information on the screen.
And S220, acquiring a corresponding image according to the image display area on the operated screen.
S230, judging whether the resolution of the image is greater than a resolution threshold corresponding to the image display area, if not, executing S240; if yes, go to step S250.
Specifically, in order to prevent the application program from collapsing due to the fact that the memory occupied by the image display is too large in the running process of the application program, the memory occupied by the image display is mainly from the size of pixel information included in the image, the size of the pixel information of the image is mainly represented by the size of the resolution of the image, the higher the resolution of the image is, the more pixels in the unit length of the image are indicated, and the larger the pixel information included at the moment is, therefore, when the corresponding image is acquired, it is first necessary to determine whether the resolution of the image meets the preset upper limit of the resolution of the image display area in which the image is located, that is, determine whether the resolution of the image is greater than the resolution threshold corresponding to the image display area, and different operations are correspondingly executed under different conditions.
S240, the image is displayed in the image display area.
Optionally, when the resolution of the image is less than or equal to the resolution threshold corresponding to the image display area, it is described that the memory occupation of the image acquired at this time meets the memory occupation upper limit set for the corresponding image display area in the running process of the application program, and at this time, the image does not need to be processed at all, and can be directly displayed in the corresponding image display area.
S250, the resolution of the image is reduced according to the resolution threshold corresponding to the image display region.
Optionally, when the resolution of the image is greater than the resolution threshold corresponding to the image display area, it is described that the resolution of the image obtained at this time is greater, and the number of pixels included is greater, so that the operating memory occupied by the pixel information of the image in the operating process of the application program is greater, and the application program is likely to be crashed. Specifically, in this embodiment, the resolution of the acquired image may be reduced by controlling the local server or the backend server.
In the present embodiment, when the image display in the application program is operated, two cases may be included: displaying images of the application program after the application program runs on the line and displaying the images in a development and test stage; after the application program runs on the line, if the resolution of the acquired image is greater than the resolution threshold of the image display area, the background server can be controlled to directly reduce the resolution of the image according to the resolution threshold of the image display area, so that the reduced image can be displayed in the image display area subsequently; when the application program performs performance testing in a development testing stage, if the resolution of the acquired image is greater than the resolution threshold of the image display area, the resolution abnormal information of the image can be stored and forwarded to a corresponding developer, the developer controls the background server to reduce the resolution of the image, or directly controls the local computer to reduce the resolution of the image according to the resolution abnormal information of the image, so that the resolution of the reduced image is less than or equal to the resolution threshold corresponding to the image display area, the memory occupation of image display in the application program running process is correspondingly reduced, and the phenomenon that the application program collapses in running is reduced.
In addition, in this embodiment, when obtaining the reduced image, the reduced image may be stored in a corresponding position in the backend server, so that when sliding to the image display area next time and needing to display the image again, the reduced image may be directly obtained without performing resolution comparison and reduction again, thereby improving the image display efficiency. Specifically, in the embodiment, the resolution of the image that may be displayed in each image display area may be tested in the development and test stage of the application program, the resolution of the image that is greater than the resolution threshold corresponding to the image display area is correspondingly reduced, and the reduced image is stored in the background server, so that when the subsequent application program runs on line, the reduced image may be directly obtained to be displayed, resolution comparison and reduction are not required again, and thus, the image display efficiency is improved.
And S260, displaying the reduced image in the image display area, wherein the resolution of the reduced image is less than or equal to the resolution threshold corresponding to the image display area.
Optionally, after the local computer or the background server is controlled to reduce the resolution of the image larger than the resolution threshold corresponding to the image display area, pixels included in the image are correspondingly reduced, so that corresponding pixel information is correspondingly reduced, at this time, the resolution of the reduced image is smaller than or equal to the resolution threshold corresponding to the image display area, which meets the upper limit value of the resolution that the image allowed to be displayed in the image display area can reach, and the reduced image is displayed in the image display area, so that the image finally displayed in the image display area can meet the resolution threshold set in the image display area, thereby reducing memory occupation during image display and reducing the phenomenon that the application program collapses during operation.
According to the technical scheme provided by the embodiment, the resolution threshold corresponding to the image display area on the screen after operation is determined, and the resolution of the image larger than the resolution threshold corresponding to the image display area is correspondingly reduced, so that the finally displayed image corresponding to the image display area can meet the requirement of the resolution threshold set in the image display area, the pixel information contained in the displayed image in the operation process is reduced, the operation memory occupied by image display is reduced, and the image display efficiency and the operation performance of the application program are improved.

In the present embodiment, when the image display in the application program is operated, two cases may be included: the image display after the application program is operated on the line and the image display in the development and test stage. Specifically, in this embodiment, mainly for the application program in the development and test stage, a corresponding exception notification bar and an exception alarm page may be popped up in the interface, and a tester performs a corresponding repair operation on an exception image according to the exception image information in the popped-up interface, so that after a subsequent application program is actually operated online, an image meeting a resolution threshold corresponding to a corresponding image display area can be directly displayed, and an exception crash phenomenon caused by an overflow of an operating memory of the application program is reduced.

And S360, receiving an image viewing instruction.
Wherein the image viewing instruction comprises a corresponding image identifier. Specifically, since the abnormal alarm page includes a plurality of detected images with resolutions greater than the resolution threshold corresponding to the image display area, if a tester needs to check specific information of an abnormal image, the tester can select the corresponding abnormal image from the abnormal alarm page to generate an image checking instruction of the abnormal image, where the image checking instruction includes an image identifier of the selected abnormal image, so as to display detailed information of the corresponding abnormal image according to the image identifier in the following.
And S370, popping up attribute information of the corresponding image according to the image identification.
