Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
With the development of imaging technology, high-pixel, high-quality pictures, such as one hundred million pixels (12032x9024px), can be easily obtained, but how to display these pictures becomes a difficult problem. At present, pixels of display devices are 1080P, 2K, 4K and the like generally, even if the display devices with the pixels of 4K are used, the pictures with 1 hundred million pixels can not be displayed without processing, so that the pictures can not be normally used without processing if the pictures are used as UI interface elements, such as head images, icons and the like.
Currently, high-pixel pictures are displayed by the following methods: and carrying out zooming processing when the picture to be displayed is decoded, wherein the obtained picture data is reduced picture data, namely a reduced bitmap, picture textures are created based on the reduced bitmap, the picture textures are sent to a frame buffer area, the textures are zoomed in the frame buffer area according to the size of a display area of a display control, and the zoomed picture textures are rendered to display equipment. However, in the above method, since the obtained bitmap is distorted by performing the scaling process during decoding of the picture, the true use of the decoded data cannot be determined during decoding, for example, if the picture is decoded and used for editing, rather than being used for displaying, the user cannot obtain the true picture data, and the edited picture is a distorted picture.
Secondly, in the existing method, the texture picture is created according to the bitmap, and when the resolution of the picture to be displayed is higher, the created texture picture is larger, occupies more memory resources, and reduces the working efficiency of the system. And then, in the rendering stage, the texture picture needs to be reduced to the size corresponding to the display area and then rendered to the display area, so that more memory resources are additionally occupied when the texture picture is created, the texture picture needs to be reduced to the size of the display area during rendering, the picture display process is complicated, and the picture display efficiency is reduced.
The invention provides a method for displaying pictures, which comprises the steps of firstly decoding a target picture to obtain an original bitmap of the target picture, obtaining a display control associated with the target picture, obtaining a display area of the display control, creating a texture picture corresponding to the original bitmap, wherein the size of the texture picture is consistent with that of the display area, and rendering the texture picture to a display memory corresponding to the display control. It can be seen from the above that, in the method, the scaling processing is not performed when the picture is decoded, and the decoded picture is the original data of the picture, so that the picture data is not distorted before the purpose of the picture is determined, and the picture is not distorted after the processing such as editing is performed based on the picture data. In addition, according to the scheme, the texture picture with the corresponding size is created according to the width and the height of the display area of the display control, which is equivalent to creating the texture picture according to needs, so that the occupation of memory resources is reduced when the texture picture is created, the phenomenon of blocking caused by the occupation of too much memory resources when the texture picture is created is avoided, and the operation efficiency of the system is improved. And because the texture picture is created as required, the size of the display area from the texture picture to the display control does not need to be reduced in the rendering step, the step of displaying the picture is simplified, and the picture displaying efficiency is improved.

Application 126 can instruct processor 104 to perform picture display method 200 to process program data 124 to display a picture with reduced memory resource usage when decoding to obtain an original bitmap and creating a texture picture.
FIG. 2 illustrates a flow diagram of a picture display method 200 suitable for execution in the computing device 100 shown in FIG. 1, in accordance with one embodiment of the present invention. The method is adapted to step S210.
Before step S210 is executed, the target picture needs to be read, where the target picture is a picture to be displayed, and the target picture is stored in the cache. The target pictures in the cache comprise: pictures downloaded through network, pictures in memory, and pictures in disk.
Next, in step S210, the target picture is decoded to obtain an original bitmap of the target picture. Specifically, the decoder decodes the target picture, and the decoder may be a system-owned decoder, for example, a system-owned Skia decoder in an Android system, or other decoders.
It should be noted that the original bitmap is picture data that has not been subjected to scaling processing after decoding the target picture, that is, the decoded picture data is real picture data, so that, under the condition that the purpose of the decoded data is unclear, the method of the present invention does not reduce the picture data, and the quality of the decoded picture data is not lost, so that the picture is not distorted after the picture data obtained by decoding is subjected to editing and other operations.
Wherein the use of the decoded data comprises: displaying a target picture based on the decoded data, editing picture data, generating a video, and the like. For example, a user edits picture data by using decoded data, instead of displaying the picture data, based on the method of the present invention, the user can acquire real picture data, and the user still acquires real picture data after editing based on the picture data, so that the quality of the picture is maintained, that is, the edited picture is not distorted.
After the original bitmap is obtained, in step S220, a display control associated with the target picture is obtained, where the display control includes Imageview, and of course, the present invention is not limited to the specific display control, and since the principle of displaying pictures by the display control is a known technology, the description is not provided herein, but all display controls capable of displaying pictures are within the scope of the present invention.
Subsequently in step S230, a display area of the display control is acquired. Specifically, each display control is associated with a picture identifier (url of a picture), the display control can be mapped according to the picture identifier, that is, the display control is determined according to the picture identifier, and since a display area of the display control (the display area is a picture display position of the picture corresponding to the display control) is pre-configured in a page file, such as an html file, the computing device 100 can directly obtain the display area of the display control from the web file.
Note that, when the target picture is displayed in full screen, the display area size is the size of the display. When a picture is taken as an icon, a head portrait, or the like, that is, when a plurality of target pictures are simultaneously displayed on a display, the display area size is the size of a part of the display, and the sum of the display area sizes is the display size.
Next, in step S240, a texture picture corresponding to the original bitmap is created. The size of the texture picture is consistent with that of the display area, and the texture picture creating process is equivalent to creating the texture picture according to needs because the size of the texture picture is consistent with that of the display area, so that the occupation of memory resources is reduced when the texture picture is created, the phenomenon of blocking caused by the occupation of too much memory resources when the texture picture is created is avoided, and the operation efficiency of the system is improved. And because the texture picture is created as required, the texture picture does not need to be reduced to the size of the display area of the display control in the rendering step, so that the expenses of memory and the like of rendering hardware can be reduced, the step of displaying the picture is simplified, the picture displaying efficiency is improved, and the capability of the rendering hardware cannot be exceeded.
In an embodiment of the present invention, the original bitmap is rendered to the graphics memory by a hardware rendering method, for example, the original bitmap is rendered to the graphics memory by a GPU, and then the step of creating the texture picture corresponding to the original bitmap specifically includes: and uploading the original bitmap to a GPU, and creating a texture picture corresponding to the original bitmap through the GPU.
Finally, in step S250, the texture picture is rendered to the display memory corresponding to the display control. According to one embodiment of the present invention, the GPU renders the original bitmap to the graphics memory, and the specific process of the GPU rendering is as follows: and sending the texture picture to a frame buffer area of the display control, and rendering the texture picture in the frame buffer area to a display memory corresponding to the display control. Of course, the present invention is not limited to the specific rendering manner, and the display memory method capable of rendering the texture image to the display control in the prior art is within the protection scope of the present invention. The display memory is also called a display card memory, stores rendering data processed or to be extracted by a display card chip, and also stores components of graphic data to be processed.
Based on the method provided by the invention, the picture is not zoomed when being decoded, and the original data of the picture is obtained after decoding, thereby ensuring that the picture data is not distorted before the purpose of the picture is determined, and the picture is not distorted after the processing such as editing and the like is carried out based on the picture data. In addition, according to the scheme, the texture picture with the corresponding size is created according to the width and the height of the display area of the display control, which is equivalent to creating the texture picture according to needs, so that the occupation of memory resources is reduced when the texture picture is created, the phenomenon of blocking caused by the occupation of too much memory resources when the texture picture is created is avoided, and the operation efficiency of the system is improved. And because the texture picture is created as required, the size of the display area from the texture picture to the display control does not need to be reduced in the rendering step, the expenses of memory and the like of rendering hardware are reduced, the step of displaying the picture is simplified, and the picture displaying efficiency is improved.

In addition, according to the scheme, the texture picture with the corresponding size is created according to the width and the height of the display area of the display control, which is equivalent to creating the texture picture according to needs, so that the occupation of memory resources is reduced when the texture picture is created, the phenomenon of blocking caused by the occupation of too much memory resources when the texture picture is created is avoided, and the operation efficiency of the system is improved. And because the texture picture is created as required, the size of the display area from the texture picture to the display control does not need to be reduced in the rendering step, the expenses of memory and the like of rendering hardware are reduced, the step of displaying the picture is simplified, and the picture displaying efficiency is improved.
