Based on described above, according to different typesetting patterns, the calculating to typesetting parameter separately below is specifically described：

First, typesetting pattern is arc typesetting

Specifically refer to Fig. 3, in the embodiment of the present invention in the generation method of E-seal typesetting parameter the first calculating side Method includes：

301st, typesetting pattern is arc typesetting, the camber line according to where pre-set dimension, display parameters calculate target seal information The dimensional parameters of the curvilinear figure of formation；

In the present embodiment, if typesetting pattern of the target seal information in preset pattern is arc typesetting, then can be with root Arc where target seal information is calculated according to the back gauge in the pre-set dimension of preset pattern, display parameters between character and preset pattern The dimensional parameters of the curvilinear figure that shape is formed.

Specifically, after the curved typesetting of target seal information, the curvilinear figure that place camber line is formed can be circular or ellipse Circle, and the curvilinear figure is in preset pattern, then by the pre-set dimension and target information that combine preset pattern Character and preset pattern between back gauge can calculate the dimensional parameters of curvilinear figure where target seal information, if curve map Shape is circle, then the dimensional parameters can be radius or diameter, if the curvilinear figure is ellipse, then the dimensional parameters can Think major semiaxis, semi-minor axis.

For example, it is assumed that preset pattern is circle, the curvilinear figure that camber line where target seal information is formed also is circle, its In, shown in canvas interface a diameter of 5 centimetres of preset pattern, the back gauge in target seal information between character and circle is 0.5 centimetre, then the diameter that can determine curvilinear figure can be 4 centimetres.

302nd, the seat of the pinpoint of arc length is preset in calculated curve figure according to dimensional parameters and presetted pixel point Mark；

In the present embodiment, the curvilinear figure that the camber line according to where pre-set dimension, back gauge calculate target seal information is formed After dimensional parameters, the pinpoint of arc length can be preset in calculated curve figure according to dimensional parameters and presetted pixel point Coordinate.

Specifically, no matter between or for curve, be made up of several pixels, between pixel away from From being certain, i.e. presetted pixel point distance, the image quality effect of presentation content is can serve to indicate that, then according to curvilinear figure Dimensional parameters and presetted pixel point distance, can with calculated curve figure preset arc length target pixel points coordinate, i.e., The coordinate of pinpoint.

In actual applications, the coordinate-system of X, Y-axis with the center of curve map as origin, can be set up, step is continued to use The preset pattern and curvilinear figure illustrated in rapid 301, it may be determined that the coordinate of X-axis left end point is (- 2,0), then assuming that Presetted pixel point distance is A, then the coordinate of next pixel is (- 2+A, 0) in the X-axis, thus method and binding curve The corresponding normal equation of figure, can calculate the coordinate of the pinpoint of default arc length.

It is understood that the default arc length in the present embodiment can be the semi-perimeter of curvilinear figure, it is also possible to more than or Less than the semi-perimeter, can according to actual needs be configured, not limit herein specifically.

303rd, the coordinate according to pinpoint calculates the length of default arc length；

In the present embodiment, the target for presetting arc length in calculated curve figure according to dimensional parameters and presetted pixel point is determined After the coordinate of point, the length of default arc length can be calculated according to the coordinate of pinpoint.

Specifically, after the coordinate of the individual fixed point of the default arc length of determination, it is possible to use air line distance formula calculates two fixed points Between air line distance, by parity of reasoning, can be by the air line distance between all adjacent fixed points in default arc length, will be all adjacent Air line distance between fixed point adds up, you can to calculate the length of default arc length.It is understood that the length of the default arc length It is approximation to spend.

It should be noted that the content that step 302 is illustrated to step 303 in the present embodiment is the length for calculating default arc length A kind of mode, in actual applications, it would however also be possible to employ other manner, such as can calculate public with reference to arc length according to dimensional parameters Formula is calculated the length for presetting arc length, is not limited herein specifically.

304th, according to target character spacing, pre-set dimension, the length of default arc length, display parameters and target seal information Number of characters, calculate target seal information in target character in preset pattern or the coordinate of curvilinear figure；

In the present embodiment, after the coordinate according to pinpoint calculates the length of default arc length, can be according between target character Away from, the number of characters of the length, display parameters and target seal information of default arc length, target character in target seal information is calculated In preset pattern or the coordinate of curvilinear figure, wherein, it is big that target character spacing can preset the length of arc length, character according to Small, number of characters is calculated, or target character spacing can also be character pitch.

In actual applications, there may be following two situations：

1st, the character length of target seal information is the length of default arc length, in such a case it is possible to target seal The original character length of information is calculated, will in display parameters character boundary character duration, with target seal information The product of number of characters as target seal information original character length, if the original character length of target seal information is not more than The length of default arc length, then illustrate target seal information can on default arc length this curve, wherein, target seal is believed The bebinning character of breath can be the first end point of default arc length, and that character can be default arc length is put at the end of target seal information Two end points.Therefore, it can believe target seal using the number of characters of the length, character boundary and target seal information of default arc length The target character spacing of breath is calculated, that is, preset the character duration * number of characters+(character in the length=character boundary of arc length Number -1) * target character spacing, the target character spacing be in target seal information between the corresponding coordinate of adjacent character away from From, after obtaining target character spacing, can according to target character spacing, pre-set dimension, the length of default arc length, display parameters with And the number of characters of target seal information, target character is in preset pattern or the coordinate of curvilinear figure in calculating target seal information.

Specifically, target character can be a character, such as bebinning character, or each in target seal information Character, it is assumed that target character is each character in target seal information, then with reference in pre-set dimension and display parameters Back gauge, it may be determined that the first end point of default arc length in preset pattern or the coordinate of curvilinear figure, for example, continuing to use step 302 Illustration, it is assumed that default arc length is the upper half girth of curvilinear figure, it may be determined that the coordinate of first end point is (- 2,0), then On the basis of the coordinate of first end point, the character duration of character boundary can be obtained in combining target character pitch, display parameters After to first end point another character curvilinear figure coordinate, in conjunction with the number of characters of target seal information, you can obtain each Coordinate of the character in curvilinear figure.

2nd, the character length of target seal information is not the length of default arc length, wherein, if target seal information is original Character length is more than the length of default arc length, then can in addition calculate the character length of target seal information, if target seal is believed The character length of breath is set smaller than the length of default arc length, then the character that can also in addition calculate target seal information is long Degree, then target character spacing now is the character pitch set in display parameters, the character length of target seal information Character duration * number of characters+(number of characters -1) * character pitches in=character boundary, obtain the character length of target seal information Afterwards, can be according to target character spacing, pre-set dimension, the word of the length, display parameters and target seal information of presetting arc length Symbol number, calculate target seal information in target character in preset pattern or the coordinate of curvilinear figure,

Specifically, assume that target character is each character in target seal information, and target seal information character Length is more than the length of default arc length, then with reference to the back gauge in pre-set dimension and display parameters, it may be determined that default arc length First end point in preset pattern or the coordinate of curvilinear figure, for example, continuing to use the illustration of step 302, it is assumed that default arc length Be the upper half girth of curvilinear figure, it may be determined that the coordinate of first end point be (- 2,0), then first end point coordinate basis On, the character length of target seal information can be more than the coordinate symmetry principle of binding curve figure the length of default arc length Part mapping to the coordinate of the lower half girth of curvilinear figure in, it is possible to determine the seat of the bebinning character of target seal information Mark, the character duration in conjunction with character boundary in target character spacing, display parameters can obtain another character after bebinning character In the coordinate of curvilinear figure, in conjunction with the number of characters of target seal information, you can obtain coordinate of each character in curvilinear figure.

It should be noted that in above-mentioned two situations, because curve map is located in preset pattern, then finally, it can It is considered to obtain coordinate of the target character in preset pattern, for example, continuing to use the content of step 301 illustration, first end point Coordinate be that coordinate in preset pattern is still (- 2,0).

It is understood that the coordinate of target character can be the center of target character in the present embodiment, in reality In, or other, can specifically be set according to actual conditions, do not limit herein.

305th, the tangent line radian for determining target character in coordinate and target seal information is typesetting parameter；

In the present embodiment, obtain in target seal information after coordinate of the target character in preset pattern or curvilinear figure, Because target seal information is arc typesetting, then the determination of the coordinate of target character cannot still determine target character in default figure Direction in shape or curvilinear figure, then can be according to the coordinate further to the target character in preset pattern or curvilinear figure Tangent line radian calculated, it is possible to the coordinate and the tangent line radian are defined as typesetting parameter, to determine target character Final display location in preset pattern or curvilinear figure.
