Abstract

The invention discloses a file conversion method and device and a file transmission system and belongs to the field of file compression. The file conversion method comprises the steps that text contents in target text files are converted into numerical value sequences in a predetermined character encoding mode, wherein numerical values in the numerical value sequences belong to a predetermined color value range interval; the numerical value sequences are divided into a plurality of color n tuples, and each color n tuple contains m adjacent numerical values in the numerical value sequences and is used for indicating the color of one pixel point, wherein n is greater than or equal to 3; target pictures generated according to the color n tuples are stored, and the pixel points in the target pictures are generated according to the color n tuples. A file compression scheme for converting text files into pictures is provided under the situation that a browser does not support an uncompressing algorithm, the compression effect similar to an existing compression algorithm is achieved, accordingly modes of decreasing text file data volume is enriched, and it is ensured that the browser can perform normal display of webpage contents.

Description

technical field [0001] The embodiments of the present invention relate to the field of file compression, in particular to a file conversion method, device and file transmission system. Background technique [0002] In the process of displaying the webpage, the browser needs to download the script text file and style text file corresponding to the webpage from the server, such as JavaScript (Java script) text file and CSS (Cascading Style Sheets, Cascading Style Sheet) text file. By parsing these text files, the browser controls the logic and display style of the web page. [0003] In order to increase the transmission rate of text files and thereby speed up the display speed of web pages, before the server sends the text files to the browser, it needs to use a compression algorithm to compress the text files, and transmit the compressed text files to the browser, thereby reducing the transmitted data Correspondingly, the browser uses a decompression algorithm to decompress ...
