Kind.
Above-mentioned each embodiment can in any combination, to obtain a kind of adding method of specific watermark；In order to
The embodiment of the present invention is more clearly described, below with a specific example, sketches a kind of optionally watermark in the embodiment of the present invention
Adding method, as shown in Figure 2, which comprises
Step 1, the upper transmitting file of user, including source file and watermark file.
Step 2, file is received, and identifies the watermark file type that user uploads；If text type, step 3 is executed；If
Step 4 is then executed by watermark file directly as watermark for picture type.
Step 3, text type watermark file is generated into watermark；Then step 4 is executed.
Step 4, it is compressed file in the file for identifying that user uploads, then identifies the source file in compressed package after decompressing
File format, and distributed source file to different processing modules according to file format, it is divided into picture processing module, Word file
At processing module, Excel file processing module, PowerPoint document processing module, Pdf document processing module and video file
Manage module.It may include the source file of a variety of file formats in the same compressed package.
Above 6 kinds of processing modules can be optionally combined, and every kind of processing module has independent implementation.
1) picture processing module, for handling picture file format；Watermark picture is placed on to the lower right corner of source file.
2) Word file processing module, for handling Word file format；Using Docx4j plug-in unit, watermark picture is arranged
For the watermark of Word file.
3) Excel file processing module, using Docx4j plug-in unit, is sequentially found for handling Excel file format
All Sheet in Excel, set watermark picture to the watermark of Excel file.
4) PowerPoint document processing module, for handling PowerPoint file format, using Poi plug-in unit, successively
All Page are found, set watermark picture to the watermark of PowerPoint file.
5) Pdf document processing module, using Itextpdf plug-in unit, is sequentially found all for handling Pdf file format
Page sets watermark picture to the watermark of Pdf file.
6) video file processing module utilizes Ffmpeg tool, call instruction for handling video file format；
D:\Program Files\ffmpeg\bin>ffmpeg–i；
D: xiaoi logo logo.mp4-vf " movie=logo.png [logo]；[in] [logo] overlay=
10:10[out]"；
D:\xiaoi\logo\output.mp4；
Generate the video file of watermarking.
Step 5, addition finishes；If addition failure, prompts failure cause；If added successfully, after generating addition watermark
File.
It is provided in this example to the main entrance of Miscellaneous Documents addition watermark.User is all without knowing operating procedure
Processor be for a user it is transparent, user only needs to provide source file and watermark picture (text).
Various software and tool are installed in client without user in this example, addition watermark can be realized.
Picture watermark and Text Watermarking, Text Watermarking is supported also to support user oneself that color is set in this example simultaneously.
Batch addition watermark is supported in this example, user, which can compress the files in batch of watermark to be added, to be uploaded.
This example can effectively simplify the complex operations step of addition watermark, and the time-consuming that this example adds watermark is very short,
