Embodiment 1

[0021] refer to figure 1 , figure 1 It is a flow chart of a GIF file rendering method provided by Embodiment 1 of the present invention. In this embodiment, the GIF file rendering method includes:

[0022] Step S11: read the GIF file by means of stream reading.

[0023] Step S12: Decoding the read GIF file and obtaining the decoded frame picture.

[0024] Step S13: rendering the acquired frame picture.

[0025] Step S14: Judging whether the number of acquired frame pictures reaches a predetermined number, if so, end rendering; otherwise, return to and execute the step of decoding the read GIF file and obtaining decoded frame pictures.

[0026] Compared with the prior art, the GIF file rendering method provided by this embodiment adopts the streaming reading method to read the GIF file, and renders it on demand, which reduces the occupation of resources, improves the efficiency of playing GIF animation, and solves the problem of The problem of excessive resource occupation...

Embodiment 2

[0028] refer to figure 2 , figure 2 It is a flow chart of a GIF file rendering method provided by Embodiment 2 of the present invention. In this embodiment, the GIF file rendering method includes:

[0029] Step S21: Read the GIF file by means of stream reading.

[0030] Step S22: Decoding the read GIF file and obtaining the decoded frame picture.

[0031] Step S23: rendering the acquired frame picture.

[0032] Step S24: Judging whether the number of acquired frame pictures reaches a predetermined number, if so, ending rendering; otherwise, returning to and executing the step of decoding the read GIF file and obtaining decoded frame pictures.

[0033] Different from Embodiment 1, in this embodiment, step S21 includes:

[0034] Step S211: Obtain the file path of the GIF file.

[0035] Step S212: Move the file pointer.

[0036] Step S213: Determine whether the file pointer has reached the target position, if so, read the GIF file; otherwise, return and execute the step ...

Embodiment 3

[0039] refer to image 3 , image 3 It is a flow chart of a GIF file rendering method provided by Embodiment 3 of the present invention. In this embodiment, the GIF file rendering method includes:

[0040] Step S31: read the GIF file by means of stream reading.

[0041] Step S32: Decoding the read GIF file and obtaining the decoded frame picture.

[0042] Step S33: rendering the acquired frame picture.

[0043] Step S34: Judging whether the number of acquired frame pictures reaches a predetermined number, if so, ending rendering; otherwise, returning to and executing the step of decoding the read GIF file and obtaining decoded frame pictures.

[0044] Different from Embodiment 1, in this embodiment, step S32 includes:

[0045] Step S321: Set a specific flag and the binary content of the last bit of the specific flag, where the binary content of the last bit of the specific flag is used to indicate the length to be moved by the file pointer. The specific flag bit is, for ...

Abstract

The invention discloses a method for rendering a GIF (Graphic Interchange Format) file. The method comprises the steps of reading the GIF file by a stream reading method, decoding the read GIF file and obtaining decoded image frames, rendering the obtained image frames, determining whether the number of the obtained image frames reaches a predetermined number, and if so, finishing rendering, otherwise, returning and executing the step of reading the GIF file and obtaining the decoded image frames. The invention also discloses a device for rendering the GIF file. Compared with the prior art, the method and the device for rendering the GIF file is characterized by reading the GIF file by the stream reading method and rendering according to requirements, and as a result, occupation of resources is reduced, the efficiency of playing a GIF animation is improved, and the problem of occupation of excessive resources when the GIF file is read in the prior art is solved.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method and device for rendering a GIF file. Background technique [0002] With the improvement of people's requirements for the application of mobile terminal equipment, the capabilities of mobile terminal equipment have become more and more powerful in today's rapid development of the IT manufacturing industry. Smartphones have become the most mainstream mobile terminal equipment due to their powerful functions. Compared with ordinary mobile phones, smart phones have an independent operating system, and users can install application programs provided by third-party service providers such as application software, games, and emails by themselves, and continuously expand the functions of mobile phones through such programs. [0003] The application of smart phone operating systems has been involved in many fields, including browsers, various business software, etc., which bring...
