The UI16b of printed driver 16 obtains zoom ratio, if the zooming parameter that operator is inputted by UI16b is percentages, as 60%, then the UI16b of printed driver 16 can directly obtain this zoom ratio x%; If page size for the purpose of the zooming parameter that operator is inputted by UI16b, if object page size is A5, then printed driver 16 also needs to calculate zoom ratio x% by the value of parent page size and object page size.
Step S203, generates data processing resolution according to zoom ratio and device resolution
The zoom ratio x% got is multiplied by the device resolution y preserved in the data structure of printed driver 16 by printed driver 16, obtains data processing resolution z, i.e. z=y*x%.Data processing resolution z is saved in data structure by printed driver 16, i.e. device resolution in the data structure of printed driver is data processing resolution z by assignment again, but this assignment is only effective to this print job.
When starting print job next time, the device resolution parameter of the data structure of printed driver is reinitialized to device resolution.
Step S204, converts source data to data bitmap according to data processing resolution
GDI15 and printed driver 16 carry out data interaction by function call, by data bitmap identical with data processing resolution for source data conversion imaging prime number.
Fig. 7 is the reciprocal process schematic diagram between GDI and printed driver.As shown in the figure, in the reciprocal process of GDI and printed driver, GDI calls the related function of print driver, such as GDI is by calling DrvEnableDriver function, make printed driver initialization, and return the DLL list of printed driver support, GDI is by calling DrvEnablePDEV function, printed driver is made to return the description of physical equipment attribute to GDI, GDI is by calling DrvCompletePDEV function, the installation of notice printed driver physical equipment completes, this function is also provided to the logic handle of the GDI of PDEV (abbreviation of physical equipment) to driver, calling in GDI function for driver, GDI calls DrvEnableSurface, surface printed driver being set up will draw is also relevant with PDEV by it.Simultaneously, print driver states in the process of function the function of adjusting back again GDI and exporting in realization, such as printed driver creates by calling EngCreateBitmap function request GDI and manages bitmap, by calling EngMarkBandingSurface function flag settings surface as binding surface, along with the establishment on surface, printed driver must make surface relevant to a PDEV by the EngAssociateSurface function calling GDI, this calls also tells GDI printed driver is which drawing function surface has hung up.Thus GDI15 and printed driver 16 carry out data interaction by function call, by data bitmap identical with data processing resolution for source data conversion imaging prime number.
Such as, set device resolution is 300DPI, and when zoom ratio is 50%, data processing resolution is 150DPI, GDI15, by data bitmap identical with data processing resolution 150DPI for source data conversion imaging prime number, converts by source data the data bitmap that per inch pixel count is at 150 to; When zoom ratio is 100% (namely without convergent-divergent), data processing resolution is 300DPI, equal with device resolution, GDI15, by data bitmap identical with data processing resolution 300DPI for source data conversion imaging prime number, converts by source data the data bitmap that per inch pixel count is at 300 to; When zoom ratio is 200%, data processing resolution be 600DPI, GDI by data bitmap identical with data processing resolution 600DPI for source data conversion imaging prime number, convert by source data the data bitmap that per inch pixel count is at 600 to.
Step S205, data bitmap and print command are sent to printer by printed driver
Data bitmap and print command are sent to the communication interface of printer by printed driver by communication interface.The data bitmap received and print command are saved in reception buffer zone by the controller of printer, simultaneously, controller processes data bitmap according to print command, such as, to every number of lines of pixels according to interpolation starting character, full stop and capacity description etc., and by the every number of lines of pixels after process according to the setting address be saved in print buffer.
Step S206, printer prints data bitmap according to device resolution
Data bitmap in print buffer is sent to printhead by the controller of printer line by line, printhead horizontal and vertical according to device resolution output bitmap data.
When device resolution is 300DPI, the pixel count of per inch is 300DPI, when zoom ratio is 50%, and, data processing resolution=300DPIx50%=150DPI, like this on horizontal and vertical, the pixel count of per inch is 150 points.Therefore, when print span is one inch, when length is the data bitmap of an inch, in print span direction, the pixel count generated during device resolution is adopted to be 300x1=300 point, the pixel count adopting data processing resolution to generate is 150x1=150 point, in print length direction, the pixel count generated during device resolution is adopted to be 300x1=300 point, the pixel count adopting data processing resolution to generate is 150x1=150 point, like this, same printer is adopted to print one inch wide, during the data bitmap of an inch wide, because the pixel quantity of the data bitmap of the pixel number ratio device resolution generation of the data bitmap of data processing resolution generation all decreases 0.5 times horizontal and vertical, therefore print span just becomes original 0.5 times, print length also becomes original 0.5 times, print area is original 0.25 times, thus achieve the object reducing printing.
When zoom ratio is 200%, data processing resolution=300DPIx200%=600DPI, the pixel count of such per inch becomes 600 points.Therefore, when print span is one inch, when length is the data bitmap of an inch, in print span direction, the pixel count generated during device resolution is adopted to be 300x1=300 point, the pixel count adopting data processing resolution to generate is 600x1=600 point, in print length direction, the pixel count generated during device resolution is adopted to be 300x1=300 point, the pixel count adopting data processing resolution to generate is 600x1=600 point, like this, same printer is adopted to print one inch wide, during the data bitmap of an inch wide, because the pixel quantity of the data bitmap of the pixel number ratio device resolution generation of the data bitmap of data processing resolution generation all adds 2 times horizontal and vertical, therefore print span just becomes original 2 times, print length also becomes original 2 times, print area is original 4 times, thus achieve amplification printing.
According to the image scaling print control program of the embodiment of the present invention, data processing resolution is generated according to zoom ratio and device resolution by printed driver, GDI and printed driver carry out data interaction by function call, by data bitmap identical with data processing resolution for source data conversion imaging prime number, printer prints data bitmap according to device resolution, thus makes source data realize convergent-divergent in proportion in print span direction and print length direction.Compared with prior art, the embodiment of the present invention utilizes GDI and printed driver to carry out rasterization process to source data, only need increase according to scaling or reduce the quantity of pixel in data bitmap, do not need to calculate pixel value according to interpolation algorithm, therefore, data processing speed is fast, and print quality is high.
