The invention discloses a kind of method that retail business POS print signal is reduced into graphic file, it is characterised in that comprises the following steps：101st, the computing device of data processing and store function and the printout mouth of businessman's POS will are connected equipped with application program.102nd, computing device obtains businessman's POS to printer output print signal, and the print signal includes printer control instruction, graphic printing instructs, N number of spirte is spliced into the mode of full graphics；103rd, computing device block searches the print control instruction set character carried in database, and enter line character comparison with the print signal obtained, therefrom the printer control instruction appeared in this print signal is deleted in filtering, retains the mode that graphic printing instruction is spliced into full graphics with N number of spirte.The present invention starts with from POS outside, i.e. print data, without carrying out complicated interface differential technique with POS system, while has also prevented the hidden danger that system invades to POS.
Description
Technical field
The present invention relates to field of computer technology, and retail business POS print signal is reduced into figure more particularly, to one kind
The method of shape files.
Background technology
" big data " has substantial amounts of application as vocabulary most burning hot at present in industry-by-industry.Thing followed number
Industry people is increasingly becoming according to the utilization of warehouse, data safety, data analysis, data mining etc. around the commercial value of big data
Scholar falls over each other the profit focus pursued." big data " very important basis is exactly reliable data source, i.e. initial data is adopted
Collection.
Retail service industry on line, all consumption datas are all stored by server, for being divided in the future
Analysis.But online under retail service industry, the amount of money of sales data, such as sale, single product, classification etc. of sale typically all protect
In POS (computer) system that retailer be present.These data are allowed to supply the application of POS outside, such as：Marketing activity, member
System etc., then need the system docking of complexity, and there are potential risks hidden danger, such as：Data from outside are stolen, and are usurped
Change.So the consumption data under current line, especially cash sales, what can not still be unified collects with accurately analyzing.
The content of the invention
The purpose of the present invention is exactly from POS outside, i.e., starts with from print data, by retail business POS print signal also
Original is analyzed into graphic file, reaches the risk hidden danger for reducing POS system.
A kind of method that retail business POS print signal is reduced into graphic file, it is characterised in that including following step
Suddenly：
101st, will there are the computing device of data processing and store function and the printing of businessman's POS defeated equipped with application program
Outlet connection；
102nd, computing device obtains print signal of businessman's POS to printer output, and the print signal includes printing
Machine control instruction, graphic printing instruction, N number of spirte are spliced into the mode of full graphics；
103rd, computing device block searches the print control instruction set character carried in database, and believes with the printing obtained
Number enter line character comparison, the printer control instruction appeared in this print signal is deleted in therefrom filtering, is retained figure and is beaten
Print instruction and N number of spirte are spliced into the mode of full graphics；
104th, graphic printing instruction is identified computing device, and single subgraph print command is a description, that is, is provided
Whether transverse and longitudinal coordinate prints for some position of (X, Y) in two dimensional surface；
105th, computing device forms dot array data by whether corresponding coordinate prints preservation, if the position prints, the position
The value put is 1；If the position does not print, the value of the position is 0；
106th, computing device forms the graphic file of N number of subgraph to N number of subgraph repeat step 105；
107th, computing device using N number of spirte be spliced into the mode of full graphics N number of subgraph be spliced into one it is complete
Big figure；
108th, computing device will scheme greatly to add bitmap images header, specifically include document size, size and resolution, i.e.,
Final graphic file can be generated.
Described step 107 comprises the following steps：
201st, computing device obtains the mode that N number of spirte in print signal is spliced into full graphics；
If the 202, connecting method is in same coordinates regional, prints twice, then the subgraph file printed twice is existed repeatedly
Same coordinate position does ' position or ' computing, generates last complete big figure；
If the 203, connecting method is has newline after subgraph, the upper left position for setting the subgraph after newline is：It is horizontal
Coordinate：The upper left corner abscissa of subgraph before newline, ordinate：The ordinate+1 in the subgraph lower left corner before newline；
If the 204th, vertically continue to print under subgraph without any splicing mark, acquiescence.
Specifically, heretofore described computing device can use known schemes of the prior art, it is relevant above-mentioned known
Technical scheme, those skilled in the art have appreciated that, will not be repeated here.
The effect of the present invention is actively obvious：The present invention start with from POS outside, i.e. print data, without with POS systems
System carries out complicated interface differential technique, while has also prevented the hidden danger that system invades to POS, because data flow is single during printout
To, can only be that POS can not write data by print.er port to printer output, printer to POS.
