Step S320 obtains the corresponding setting regions in person's handwriting region, and determines the center pixel line in the setting regions
And each non-central pixel line of item.
Wherein, setting regions includes at least the person's handwriting region.In the specific implementation process, setting regions is specially to include
The rectangular area in the person's handwriting region, also, two sides in rectangular area are parallel with center pixel line, and another two in rectangular area
Perpendicular to center pixel line, the length on another two sides is equal to the maximum person's handwriting width in person's handwriting region for side.
As shown in Figure 2 a, the person's handwriting region of hand-written pencil person's handwriting of the person's handwriting region 21 between person's handwriting point A and person's handwriting point B,
Setting regions comprising person's handwriting region 21 is rectangular area 22, and two long sides of the rectangular area 22 are parallel with center pixel line,
Two short sides of the rectangular area 22 are perpendicular to center pixel line, and two bond lengths of the rectangular area 22 are equal to person's handwriting
Maximum person's handwriting width (i.e. person's handwriting width corresponding to person's handwriting point A) in region 21.
Further, it is determined that center pixel line and the non-central pixel line of each item in the setting regions.Wherein, middle imago
The direction of plain line and the non-central pixel line of each item is consistent with the extending direction of hand-written pencil person's handwriting, also, center pixel line and
Each non-central pixel line of item forms the setting regions.
Step S330 determines that all pixels point position of center pixel line is the first colored pixels point-rendering position.
The all pixels point position set in center pixel line in the present embodiment is the first colored pixels point-rendering position,
It will, however, be understood by those skilled in the art that can also be according to actual business demand, by the part position in center pixel line
The drafting position for being set to the second colored pixels point is installed, and the non-second colored pixels position in center pixel line is determined as first
Colored pixels point-rendering position.
Step S340 determines the first colored pixels point-rendering position and the second colored pixels point of the non-central pixel line of each item
Draw position.
Wherein, the accounting of the second colored pixels point number of every non-central pixel line and the first colored pixels point number is being just
It is relevant to the spacing of this non-central pixel line and center pixel line.
In the specific implementation process, one of following manner can be used or a variety of combinations determines the non-central picture of each item
First colored pixels point-rendering position of plain line and the second colored pixels point-rendering position.
The non-central pixel line of mode one: every is corresponding with respectively different presetted pixel length, and every non-central picture
Spacing of the corresponding presetted pixel length negative of plain line about this non-central pixel line and center pixel line.It is i.e. non-according to every
The spacing of center pixel line and center pixel line is that corresponding presetted pixel length is arranged in every non-central pixel line, and makes every
