Detailed Description
In order to solve the problems of inconvenient use and poor overall effect caused by manually adjusting the character position to realize the character lace, the embodiment of the invention provides a method for drawing the symbol lace.
A method for drawing a symbol lace according to an embodiment of the present invention, as shown in fig. 1, includes:
and 102, automatically drawing the lace by taking the base line as a standard.
The method and the device for drawing the symbol lace provided by the embodiment of the invention firstly set a base line, then automatically draw the symbol lace according to the position of the base line, specifically determine the starting and ending position and the symbol interval of the drawing lace according to whether the connection of two adjacent base line segments is smooth, and then draw the symbol lace. The problems of inconvenient use and poor overall effect caused by manually adjusting the character position to realize the character lace are solved.
A method for drawing a symbol lace according to a second embodiment of the present invention is described below with reference to the accompanying drawings, where the method for drawing a symbol lace includes:
as shown in fig. 2, step 201, setting a baseline on the layout;
in the step, the position of the base line is manually input, specifically, the information of the base line is input; the base line comprises a direct line, a broken line and a curve; for polylines, the baseline data is composed of a number of nodes; for a curve, the baseline data is composed of a number of nodes and control points. The nodes are the endpoints of the straight line segments in the polyline and the endpoints of the curved line segments in the curve. Control points are information points describing the radian of each curve segment in the curve.
In the embodiment of the invention, the base line is a straight line.
in this step, the symbol used by the lace is manually input, and the symbol may be a character or a special symbol. For example, character a is entered, with font of doutum and font size of three.
in this step, taking three nodes on the baseline as an example, as shown in fig. 3, the three nodes are respectively a node 1, a node 2 and a node 3; selecting the node 2 and the node 3 as a starting point and an end point respectively, and determining the current base line segment; the previous baseline segment is determined by node 1 and node 2.
in this step, it is determined whether the connection between the current baseline segment and the previous baseline segment is smooth, and the determination criterion specifically includes:
judging the angle of the connection angle between the current base line segment and the previous base line segment, wherein the connection angle takes the intersection point of the current base line segment and the previous base line segment as a vertex, and the vertex is the starting point of the current base line segment or the end point of the previous base line segment; when the connection angle is 180 degrees, the connection between the current base line segment and the previous base line segment is smooth; when the included angle is not 180 degrees, the connection between the current base line segment and the previous base line segment is not smooth;
and if the current base line segment is the first base line segment of the base line, judging that the connection between the current base line segment and the previous base line segment is not smooth.
When the current base line segment and the previous base line segment are both straight line segments, the connection angle is the included angle between the current base line segment and the previous base line segment; or,
when the current base line segment and the previous base line segment are both curve segments, the connection angle is an included angle between a front control line of the current base line segment and a rear control line of the previous base line segment; a front control line of the current base line segment is specifically a tangent of the current base line segment at the intersection point; a rear control line of the previous base line segment is specifically a tangent of the previous base line segment at the intersection point; or,
when the current base line segment is a straight line segment and the previous base line segment is a curve segment, the connection angle is an included angle between the current base line segment and a rear control line of the previous base line segment; or,
and when the current base line segment is a curve segment and the previous base line segment is a straight line segment, the connection angle is the included angle between the previous control line of the current base line segment and the previous base line segment.
In the embodiment of the invention, the current baseline segment and the previous baseline segment are straight segments and are on the same straight line, so that the connection is considered to be smooth.
in this step, according to the judgment result of whether the connection is smooth in step 204, the starting position of the drawing symbol lace is determined, and the method for determining the starting position specifically includes: if the connection is smooth, drawing the initial position of the symbol lace on the current base line segment, and extending the position of the starting point of the current base line segment by half symbol width forwards;
and if the connection is not smooth, drawing the starting position of the symbol lace on the current base line segment as the starting point of the current base line segment.
In the embodiment of the invention, the connection between the current base line segment and the previous base line segment is smooth, so that the initial position of the drawn symbol lace is the position of extending backwards by half the symbol width from the starting point of the current base line segment, namely the node 2.
After the initial position of the drawing symbol lace is determined, the termination position of the drawing symbol lace needs to be determined, and the method for determining the termination position specifically comprises the following steps:
if the current base line segment is the last base line segment of the base line, drawing a termination point of a symbol lace on the current base line segment, wherein the termination point is the end point of the current base line segment;
and if the current base line segment is not the last base line segment of the base line, drawing a termination point of the symbol lace on the current base line segment, and extending the termination point of the current base line segment backwards by half the symbol width.
In the embodiment of the invention, the current base line segment is the last base line segment of the base line, so that the terminal point of the current base line segment, namely the node 3, is taken as the terminal point for drawing the symbol lace.
in this step, a symbol interval, which is a length of a base line between centers of two adjacent symbols, is calculated based on the starting and ending positions of the drawn symbol lace obtained in step 205 and the symbol width determined by the font size set in step 202.
In general, the symbol interval is the same as the word width, or a symbol interval range or the number of symbols inserted into the current base line segment may be manually set, and the symbol interval may be further calculated by the system according to the manually set range or the number of symbols inserted into the current base line segment.
