Specific embodiment
Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings, it should be understood that preferred reality described herein
Apply example only for the purpose of illustrating and explaining the present invention and is not intended to limit the present invention.
Fig. 1 is the flow chart of the method for the pixel device in extraction domain according to the present invention, right below with reference to Fig. 1
The method of pixel device in extraction domain of the invention is described in detail.
Firstly, in step 101, the customized pixel array normative document of user, comprising:
The input of pixel criterion file is defined to replace the input of interface control, to simplify input operation；
Define the abbreviated form of pixel array device, the convenient output to pixel array file；
Standard pixel array is defined according to demand, so as to being quickly converted the output of standard pixel device；
Customized figure layer determines the effective coverage of domain and the effective coverage of standard pixel device；
The line number omitted and columns are defined, to reduce the size of pixel array file and the convenience checked；
The specified position for saving output file of definition, the convenience searched so as to user.
In step 102, pixel criterion file and standard pixel array are checked.
In this step, user is by the figure layer to pixel criterion file, the line number and columns of omission, and device whether there is
Deng being checked one by one.Judge that this document prompts user's wrong content if there is mistake with the presence or absence of mistake；If no
Whether mistake, the then effective coverage for carrying out each device composed by check criteria pixel device again meet standard pixel device
Effective coverage.If conditions are not met, then prompting user's error message, exit command, if it is satisfied, then carrying out next step.
In step 103, the effective coverage of domain and the effective coverage of standard pixel array are calculated.
After above check all effectively, in this step, according to the information of the figure layer of definition, search is all to use the figure
The figure of layer, then calculates the effective coverage of all figures, obtains the effective coverage of the domain eventually by merging, the effective district
Domain is a bigger rectangle.
Standard pixel device is opened again, and search uses all figures of figure layer, calculates the effective coverage of all figures, pass through
Merge the effective coverage for finally obtaining standard pixel device, which is a small rectangle.
In step 104, lattice cutting is carried out to the effective coverage net of domain.
In this step, the effective coverage of domain is cut into one by one according to the effective coverage of standard pixel device
Grid to be checked, and the line number to be extracted and columns is calculated.The present invention uses the strategy process of grid cutting, simplifies
Process realizes rapidly extracting.
It is ready to complete above, then checks that defined output file whether there is, if it does not, created, if
In the presence of then directly opening the output file.
In step 105, grid is traversed, extracts pixel device, is stored into csv file.
In this step, according to the grid after cutting, traversal one by one is carried out.
First according to the size of grid, the region is inquired with the presence or absence of device, if existed without device, sky is written
Output file then judges that the device name of the device is the name of standard pixel device if there is device again, if
It is the name of standard pixel device, then the customized standard pixel array of user is written in output file, if the device
Name is not the name of standard pixel device, then according to the device name of device, is converted to the customized abbreviated character of user, and
It is written in output file, until grid is all traversed and finishes.Using the lookup to grid and to the comparative approach of device name,
Realize quickly output.
So far, the csv file of pixel device is just extracted and is finished.Using the lookup to grid and to the comparison side of device name
Method realizes quickly output.
In step 106, the file of output is stored.
In this step, output file is stored to specified position.
