Problems solved by technology

However, since the Webp image format is a new type of image format, most target devices, such as browsers, are developed for traditional image formats, and there is a problem of not supporting (that is, rendering failure) when accessing network images. After the failure, it is necessary to reload the rendering or change the image format, resulting in a decrease in the overall efficiency of network image access

Embodiment 1

[0068] As a new image format, the Webp format often faces the support (compatibility) problem (requirement) of the network image access terminal (such as a browser) for this format, which in turn affects the access or response efficiency of network images. For example, when the browser accesses the image of the server through the network, if the support detection is not performed, the server directly sends the image in the Webp format with a smaller "volume" to the browser, which may cause the image to be loaded because the browser does not support the image in this format. If rendering fails, the server needs to resend images in other formats, which affects network image access or response efficiency and user experience.

[0069] When a picture in Webp format is used in a network environment, after the access terminal sends an access request, if the accessed terminal can know that the access terminal has the ability to support pictures in Webp format, it can send the pictures ...

Embodiment 2

[0086] In the above embodiment, after the access terminal judges that the pictures in Webp format are supported, the object of the invention is achieved by receiving the pictures in Webp format returned by the accessed terminal according to the access request. However, if the same access terminal performs the support judgment operation of the Webp format picture every time it visits, it will actually be unnecessary repetition, resulting in a waste of processing resources. For this reason, in this embodiment, after the supportability judgment of the Webp format picture is carried out for the first time, if the access terminal supports the Webp format picture, then mark it and set the Webp format picture support flag, so that when the access terminal performs the next visit, It is no longer necessary to perform the supporting judgment operation of the Webp format picture, and directly take corresponding measures. Here, setting the Webp format image support flag can include the f...

Embodiment 3

[0099] The foregoing two embodiments describe the situation of realizing network picture access based on Webp format pictures from the perspective of the accessing terminal. The following describes from the perspective of the accessed terminal, that is, a method for responding to a network picture access request provided by this embodiment. see image 3 , the figure shows the flow of a method for responding to a network picture access request described from the perspective of the accessed end, the flow includes:

[0100] Step S301: After receiving the access request, send a Webp format picture support detection message to the access terminal to trigger the access terminal to obtain a preset standard Webp format picture, and extract the attribute value of at least one attribute of the standard Webp format picture;

[0101]After receiving the access request sent by the access terminal, the accessed terminal will usually respond to the request of the access terminal in a traditio...

Abstract

The embodiment of the invention discloses a network picture access method. The method includes the steps that a preset standard picture in the Webp format is acquired, and the attribute value of at least one attribute of the standard picture is extracted; the standard picture is loaded and rendered; whether the attribute value of the attribute extracted before the standard picture is loaded and rendered is the same as the attribute value of a corresponding attribute after the standard picture is loaded and rendered or not is judged, if yes, an access request for access to a network picture in the Webp format is sent, and a response message for returning the network picture in the Webp format is received so as to achieve access; if not, an access request for access to the network picture in a supported format different from the Webp format is sent, and a response message for returning the network picture in the corresponding format is received so as to achieve access to the network picture. The embodiment of the invention further discloses a network access request response method and a device and system corresponding to the method. Through the network picture access and access request response method and the device and system corresponding to the method, the network picture access (response) efficiency can be improved.

Description

technical field [0001] The present application relates to the technical field of information processing, and in particular to a method for accessing network pictures, a method for responding to network picture access requests, and corresponding devices and systems. Background technique [0002] The Webp image format is a new image format that has emerged in recent years. In the case of the same image quality, pictures in Webp format occupy less storage space than pictures in other formats (such as JPEG format, bmp format, png format, etc.), and the resources consumed for transmission on the network are significantly reduced, and the transmission time is significantly reduced. also greatly shortened. According to tests, in the case of lossy compression, the volume of Webp format images is 25% to 34% smaller than that of JPEG format images of the same quality; in the case of lossless compression, it is 34% smaller than PNG format images generated by libpng About 26% smaller ...
