Please refer to Fig. 6, in the present embodiment, close-packed lattice area determination step specifically comprises following sub-step:
Step S300: upper side frame determining step: the dot matrix of word cell of vertically lining by line scan.The concrete direction of scanning of the present embodiment can be selected according to specific needs, such as, can scan from top to bottom, or scan from bottom to up.
Step S301: in above scanning process, if the dot matrix number of the top a line is A, when the dot matrix number of the row scanned by stipulated number is greater than A, using the upper side frame of the horizontal line corresponding to this journey as close-packed lattice region, records the coordinate position of this upper side frame.In the present embodiment, stipulated number also can be arranged as the case may be in conjunction with concrete direction of scanning, and the Default Value that can be electronic installation also can carry out self-defined setting by user by user interface.When direction of scanning be from top to bottom time, the dot matrix number A of the top a line of such as word cell is 3, when stipulated number is first time, if first time scans certain a line mid point battle array number and is greater than 3, horizontal line then corresponding to this row is as the upper side frame in close-packed lattice region, such as, when stipulated number is second time, if then scanning certain a line mid point battle array number is greater than 3 for the second time, horizontal line then corresponding to this row is as the upper side frame in close-packed lattice region, certainly, stipulated number also can be the number of times that even third time is above for the third time; When direction of scanning be from bottom to up time, when being last to fixed number of times, if scan certain a line mid point battle array number to be for the last time greater than 3, horizontal line then corresponding to this row is as the upper side frame in close-packed lattice region, such as, when stipulated number is second from the bottom time, if second from the bottom certain a line mid point battle array number of scanning is greater than 3, then the horizontal line corresponding to this row is as the upper side frame in close-packed lattice region, certainly, stipulated number also can be the number of times of third from the bottom time more than even third from the bottom time.
Step S302: lower frame determining step: the dot matrix of word cell of vertically lining by line scan, certainly in some embodiment, this step can be omitted, and next step S303 is directly realized by the scanning result of step S300.
Step S303: set the dot matrix number of bottom a line as B, when the dot matrix number of the row scanned by stipulated number is greater than B, using the lower frame of the horizontal line corresponding to this journey as close-packed lattice region, records the coordinate position of this lower frame.In this step, the setting of stipulated number and usage are similar to step S 301, and difference is only the difference of direction of scanning.When direction of scanning be from bottom to up time, the dot matrix number B of bottom a line of such as word cell is 4, when stipulated number is first time, if first time scans certain a line mid point battle array number and is greater than 4, horizontal line then corresponding to this row is as the lower frame in close-packed lattice region, such as, when stipulated number is second time, if then scanning certain a line mid point battle array number is greater than 4 for the second time, horizontal line then corresponding to this row is as the lower frame in close-packed lattice region, certainly, stipulated number also can be the number of times that even third time is above for the third time; When direction of scanning be from top to bottom time, when being last to fixed number of times, if scan certain a line mid point battle array number to be for the last time greater than 4, horizontal line then corresponding to this row is as the lower frame in close-packed lattice region, such as, when stipulated number is second from the bottom time, if second from the bottom certain a line mid point battle array number of scanning is greater than 4, then the horizontal line corresponding to this row is as the lower frame in close-packed lattice region, certainly, stipulated number also can be the number of times of third from the bottom time more than even third from the bottom time.
Step S304: left frame determining step: the dot matrix of word cell of lining by line scan in the horizontal direction.The concrete direction of scanning of the present embodiment can be selected according to specific needs, such as, can scan from left to right, or scan from right to left.
