[0005] In the process of realizing the embodiment of the present invention, the inventor found that: after the document is converted into a graphics device interface file by a virtual printer, the size of the graphics device interface file is often nearly a hundred times larger than the document, and when the network transmission speed is constant, the sharing speed is also therefore nearly a hundred times lower; thus slower sharing of documents

example 1
[0054] Assume that the text file to be shared is 147KB, and the printout Joint Photographic Experts Group (JPG) file is 260KB.
[0055] Step S101: input the text file that needs to be printed, record the size of the text file as TL=147KB, and enter step S102;
[0056] Step S102: Perform virtual printing, output the graphic interface file, record the size of the graphic interface file corresponding to the first page as P1L=260KB, and enter step S103;
[0057] Step S103: compare the size of P1L and TL, if P1L is greater than or equal to TL, go to step S104, otherwise go to step S108;
[0058] Step S104: directly send the text file to other video conferencing terminals or IM users, and enter step S105;
[0059] Step S105: each terminal inputs the text file to the virtual printer for printing, outputs the graphic interface file, and enters step S106;
[0060] Step S106: the video conferencing system or the IM terminal loads the graphical interface file, and proceeds to step S107...
example 2
[0063] Suppose the text file to be shared is 941KB, and the JPG file to be printed out is 260KB.
[0064] Step S101: input the text file that needs to be printed, record the size of the text file as TL=941KB, and enter step S102;
[0065] Step S102: Perform virtual printing, output the graphic interface file, record the size of the graphic interface file corresponding to the first page as P1L=260KB, and enter step S103;
[0066] Step S103: compare the size of P1L and TL, if P1L is greater than or equal to TL, go to step S104, otherwise go to step S108;
[0067] Step S108: record the multiple of TL and P1L+1 as: N=TL / P1L+1=941 / 260+1=4, enter step S109;
[0068] Step S109: Transmit the graphical interface files on pages 1 to 4 to each video conferencing terminal or IM client, and proceed to step S1110;
[0069] Step S110: the video conferencing system or the IM terminal loads the graphic interface files on pages 1 to 4, and proceeds to step S102;
[0070] Step S111: Send the ...

Abstract
The embodiment of the invention discloses a file transmission method and a file transmission device. The file transmission method comprises the steps of determining a file size of a document file to be transmitted; transforming the document file to a graphic interface file, and determining whether the file size of one page of the graphic interface file is smaller than the file size of the document size or not; transmitting the graphic interface file of the front pages with setup quantity of the graphic interface file to a share target end of the document file if the file size of one page of the graphic interface file is smaller than the file size of the document file; and ensuring the size of the graphic interface file of the front pages with the setup quantity of the graphic interface file is smaller than the file size of the document file. The graphic interface file is unnecessary to transmit in one step, only the graphic interface document of the front pages with the setup quantity of the graphic interface file, the file size of the graphic interface file which is transmitted at the first time is small, so that the document file can be presented in time on the share target end, and the document file share speed can be enhanced.
Description
technical field [0001] The invention relates to the field of communication technology, in particular to a file sending method and device. Background technique [0002] In application environments such as video conferencing systems and instant messaging systems, document sharing is required. [0003] For the user, the user hopes to see the content of the shared document as soon as possible. [0004] At present, the general implementation scheme of shared documents is: the terminal uses virtual printing technology to convert the document into a graphical interface file, and then sends the graphical interface file to other terminals through the shared server; the above-mentioned other terminals display the graphical interface file after receiving it, thereby completing Document sharing. [0005] In the process of realizing the embodiment of the present invention, the inventor found that: after the document is converted into a graphics device interface file by a virtual printe...
