Abstract
The present invention relates to a kind of printing watermark generation methods instead of artificial signature, for solving existing office system or printing in examination & approval of manually signing in security audit approval system, caused inefficiency problem.A kind of printing watermark generation method instead of artificial signature provided in an embodiment of the present invention includes: the method that signature watermark generation or stamped signature watermark generate and be stored in database；Search signature watermark in database automatically in printing, Printed to File by virtual printer on.It can be when document be examined using the method for the embodiment of the present invention, approver's signature or stamped signature is automatically generated to be automatically printed at document signature in printout, to further increase the efficiency of approval signature, and signified signature contents or signature content of the invention include but is not limited to name, date, time, signature contents change is convenient, can freely add content.
Description
Technical field
The present invention relates to field of computer technology more particularly to a kind of printing watermark generation methods for replacing manually signing.
Background technique
Many companies will print several hundred parts of promotional pamphlets or file daily now, and former printer is recorded using special software
Enter, no added watermark function, to sign name, date, phone in signature after printing.Every part of promotional pamphlet or file are all one
The repetition of sample is worked, and workload is quite big.There is printer to support watermark function later, one column of name is just then set as water
Print, every part of printout in this way, which is all defaulted, has signed name, alleviates the workload of many staff, but can only add one,
Date and phone still want oneself hand-written.User is badly in need of the versatile printer of a printed signature at present, and it is unlimited to sign
It is formed on special printer, signature position is adjusted freely, cannot be only fixed to that certain is irremovable, and signature contents are changed not
Convenient, addition content is not free.
Summary of the invention
In view of the deficiencies of the prior art, the present invention proposes a kind of printing watermark generation methods instead of artificial signature, should
Method causes for solving existing office system signature printing or printing in examination & approval of manually signing in security audit approval system
Inefficiency, signature contents change it is inconvenient, the problems such as addition content is not free.
A kind of printing watermark generation method instead of artificial signature:
Include the following steps:
A. using the file header of programming language parsing formatted file, the file header data block portions of formatted file are found；
B. using the file header of programming language parsing PNG format file, the file header picture number of PNG format file is searched
According to block portion point；
C. using the pattern algorithm of programming language the text or picture turn in the data block portions of arbitrary format file
It changes watermark signature column into, is inserted into the video data block part in PNG file, form the PNG file with signature；
D. the background of programming language removal PNG file is utilized；
E. virtual printer driver is write；
F. virtual printer calls true print module；
G. when virtual printer submits print out task, the PNG file with signature column, it is added to the file that need to be printed
In, generate temporary file；
H. temporary file is printed.
It further, is VC++ C++ either Java using the programming language.
Further, in step b described in a kind of printing watermark generation method instead of artificial signature, formatted file is
JPG formatted file DOC formatted file either DWG formatted file.
Further, a kind of printing watermark generation method instead of artificial signature is applied examines in office system or printing
The system of criticizing.
It further, include name, date, phone instead of the content of artificial signature.
Detailed description of the invention
Fig. 1 is the method flow diagram of technical solution of the present invention.
Fig. 2 is the file header of PNG format file.
Fig. 3 is electronic signature paper sample schematic diagram.
Specific embodiment
Illustrate a specific embodiment of the invention with reference to the accompanying drawings of the specification, the following are two embodiments:
Embodiment one, as shown in Figure 1, Figure 2, Figure 3 shows, be the method flow diagram of technical solution of the present invention, it can be seen that this
Invention specifically comprises the following steps:
Step 101: utilizing the file header of programming language parsing formatted file；
Step 102: finding the file header data block portions of formatted file；
Step 103: utilizing the file header of programming language parsing PNG format file；
Step 104: searching the file header video data block part of PNG format file；
Step 105: using the pattern algorithm of programming language the text or picture turn in the data block portions of step 102
It changes watermark signature column into, is inserted into the video data block part in step 104 in PNG file
Step 106: forming the PNG file with signature；
Step 107: utilizing the background of PNG file of the programming language removal with signature；
Step 108: the PNG file with signature is stored in virtual printer；
Step 109: writing virtual printer driver；
Step 110: virtual printer calls true print module；
Step 111: when virtual printer submits print out task, the PNG file with signature, being added to the text that need to be printed
In part；
Step 112: generating temporary file；
Step 113: printing temporary file.
Embodiment two is as follows:
A. text or extended formatting picture are converted into watermark signature or watermark stamped signature using image processing techniques and inserted
Enter and generate PNG into file, as watermark file, is stored in database；
B. it in conjunction with existing office system or printing approval system, is provided to existing office system or printing approval system rich
Rich application programming interfaces, provide watermark calling interface.
C. virtual printer driver is write, virtual printer calls true print module, and virtual printer submission is beaten
When print task, the automatic signature watermark searched in database or signature seal are superimposed the watermark file preset, approver's label
Word or stamped signature are automatically printed at document signature in printout, mimeograph documents.
More than, by having illustrated embodiments of the present invention, the above-mentioned signature contents pointed out or signature content
Including but not limited to name, date, time, and the scope of the present invention are not limited to above-mentioned illustration, recorded in claim
In the range of, it can be changed, be deformed according to purpose.
