Detailed Description
The technical solutions in the embodiments of the present invention will be described below with reference to the drawings in the embodiments of the present invention.
Referring to fig. 1, fig. 1 is a word processing method according to an embodiment of the present invention, including the following steps:
step S101, obtaining a contour line and a plurality of contour points of the character to be processed.
The font of the character to be processed can be a bitmap font or a vector font. The style of the characters to be processed can be common characters, and also can be artistic characters such as hollow characters and the like.
The above-mentioned obtaining the contour line and the plurality of contour points of the character to be processed may be obtained by analyzing the font file. Specifically, the font file may be a font file designed by a font designer based on a font library, and the font file includes a plurality of contour points and position information of the contour points. The contour points can embody the contour characteristics of the character to be processed. And analyzing the font file to obtain a plurality of contour points of the character to be processed, and determining the contour line of the character to be processed based on the contour points.
In addition, the above-mentioned obtaining of the contour line and the plurality of contour points of the character to be processed may also be obtained by identifying the contour line of the determined character through a contour identification algorithm, so as to implement the bordering on the determined character.
And S102, determining a normal corresponding to each contour point based on the contour line.
In this step, the normal is a straight line which is located on the plane where the contour line is located and perpendicular to the tangent of the contour line, and the normal of each contour point can be determined by respectively passing through the contour points to form the normal of the contour line. Specifically, a tangent of the contour line may be drawn through each contour point, and then a perpendicular of the corresponding tangent through each contour point may be drawn to obtain the normal.
Step S103, respectively determining a first target point on each normal line according to a target edge adding value, wherein the minimum value of the distance between the first target point and the contour line is equal to the target edge adding value;
specifically, a distance calculation formula between two points may be adopted, the contour point is used as a first point, the distance between the first point and the second point is used as the target bordering value, and the second point is determined on the normal of the first point, at this time, if no other normal passes through the determined second point, that is, the second point has and can only make a perpendicular line perpendicular to the contour line, and the perpendicular point is the first point, it is described that the first point is the closest point to the second point among all contour points on the contour line, that is, the distance value between the second point and the first point is the minimum distance value between the second point and the contour line, and therefore, in this case, the determined second point may be used as the first target point. However, when the second point is an intersection of at least two normals, that is, the second point may make at least two perpendicular lines perpendicular to the contour line, the first point is only a perpendicular point of one of the normals, and since the distance values of the second point from different normals to the contour line may be different, so that there are a plurality of distance values of the second point relative to the contour line, at this time, it is necessary to calculate the distance values of the second point from other normals to the contour line, and if all the other distance values are greater than or equal to the target added value, it is determined that the first point is still the closest point to the second point among all contour points on the contour line, that is, the distance value between the second point and the contour line is the minimum value of the distance between the second point and the contour line, and in this case, the determined second point may be used as the first target point. However, when the distance value between the second point and the contour line along the other normal lines is smaller than the target bordering value, it means that the minimum distance value between the second point and the contour line is smaller than the target bordering value, so the second point cannot be used as the first target point. If the second point on the normal cannot be used as the first target point, a third point may be determined near the normal, wherein a distance value between the third point and the second point is ensured to be the target bordered value, then, by the above verification method, it is determined whether the distance value between the third point and the first point is a minimum distance value between the third point and the contour line, if so, the third point is used as the first target point corresponding to the first point, if not, according to the step of determining the third point, a fourth point is further determined near the normal, and the above steps are repeated until the first target point corresponding to the first point is determined. And according to the method, the first target point is determined on or near each normal.
The target value may be a fixed value or a relative value. For example, when the word to be processed is a bitmap font, the target bordered value may be a fixed pixel value. When the character to be processed is a vector font, since the vector font is usually scaled, if a fixed pixel value is still applied, the added side line appears thinner when the vector font is enlarged to a relatively large character, and the added side appears thicker when the vector font is reduced to a relatively small character, so that the whole appearance of the font is affected, by setting the target margin value to a relative value, the target margin value can be scaled correspondingly with the scaling of the character, for example, the size of a certain form (hereinafter referred to as "reference form") of the vector font can be used as a margin reference to determine the margin value (hereinafter referred to as "original margin value") of the required margin, when the margin is specifically added, the size of the character to be added can be obtained first, and then the scaling ratio k of the character to be processed with respect to the reference form can be determined, and manually setting the original margin width value D, so as to obtain a target margin value D through k and D, wherein D is k x D.
And S104, sequentially connecting all points in a target point set to form a target boundary line of the character to be processed, wherein the target point set comprises the first target point, and all points in the target point set are respectively positioned outside or inside the contour line.
Wherein, the added edge can be an outer edge determined by expanding towards the outside based on the contour line or an inner edge determined by contracting towards the inside based on the contour line; and each normal line passing through the contour point respectively comprises a symmetrical point with the same distance value with the contour point inside and outside the contour line, so that when the outer edge of the character to be processed needs to be added, the target point can be determined outside the contour line; when the inner edge of the character to be processed needs to be added, the target point can be determined in the contour line.
Specifically, as can be seen from step S103, the minimum distances between all the first target points and the contour lines determined in step S103 are the target added edge values, and therefore, all the determined first target points are respectively used as the points in the set of target points, and all the points in the set of target points are sequentially connected through smooth curves, that is, all the first target points are sequentially connected to form the target boundary line, at this time, the minimum distances between all the points on the target boundary line and the contour lines can be regarded as the target added edge values, so that the target boundary line can better embody the shape characteristics of the contour lines, and the problem of poor edge adding effect caused by a large difference between the shape of the determined boundary line and the shape of the contour lines in the prior art is solved.
Optionally, the determining, according to the target bordering value, the first target point on each normal line respectively includes:
determining the maximum boundary line of the characters to be processed according to a preset maximum adding value;
respectively calculating first target distance values between all points in a preset area of each normal line and the contour line, wherein the preset area is an area where the normal line is located between the contour line and a maximum boundary line, and the first target distance value is the minimum value of the distance between the point on the normal line and the contour line;
and determining a point on the normal where the first target distance value is equal to the target bordering value as the first target point.
When the function of adding edges of characters is set, a maximum adding edge value capable of adding edges is usually set for the determined characters to be processed, so that the maximum boundary line corresponding to the maximum adding edge value can be determined according to the method provided in the above steps S101 to S104 by the maximum adding edge value.
The preset area is a line segment cut on the normal line, and the line segment is a line segment of which the normal line is positioned between the contour line and the maximum boundary line. Since the line segment is located between the contour line and the maximum boundary line, the first target point is actually determined on or near the line segment during the edge-adding process, and therefore, before the actual edge-adding, the minimum distance value (first target distance value) between each point on the line segment and the contour line, that is, the coordinate (hereinafter referred to as "edge-adding coordinate") corresponding to one dimension of each point on the line segment is extended, and the first target distance value of the point is used as the coordinate value of the extended edge-adding coordinate.
When the point in the preset region is an intersection of at least two normal lines, the bordering coordinate value of the intersection may be determined according to the method in step S103, and specifically, the bordering coordinate value of the intersection is the minimum distance between the intersection and the contour line.
Optionally, before all the points in the target point set are sequentially connected to form a target boundary line of the word to be processed, the method further includes:
determining at least one second target point between any two adjacent normals, wherein the minimum distance value of the distance values from the second target point to each contour point is equal to the target adding value;
and taking the second target point as a point in the target point set.
Specifically, the second target point may be further determined between any two adjacent normals, where a minimum distance value among distance values from the second target point to each of the contour points is guaranteed to be equal to the target added value, and since the plurality of contour points are extracted from the contour line and can represent the contour feature of the contour line, and a minimum distance value among distance values from the second target point to each of the contour points is equal to the target added value, the target added value may be used as a minimum distance value between the second target point and the contour line, and the second target point may be used as a point in the target point set, so that the number of points in the target point set may be further increased, and a target boundary line formed by connecting the target points may better represent the shape feature of the contour line.
Optionally, an area formed by the maximum boundary line, the contour line, and the normal line together is a bordered area, and the determining of the at least one second target point between two adjacent normal lines includes:
respectively calculating second target distance values between all points in the edge adding area and the contour lines, wherein the second target distance values are equal to the distance values between the points in the edge adding area and the contour points with the minimum distance in the contour points;
and determining a point in the bordered area at which the second target distance value is equal to the target bordered value as the second target point.
Specifically, in the actual edge adding process, the determined target points are all points between the contour line and the maximum boundary line, and on the basis that the edge adding coordinates of the points on the preset area are determined in the above steps, the edge adding coordinates of all the points in the edge adding area can be further calculated in the present embodiment.
In the text design, since the text is usually arranged in a virtual grid, for example, a grid of 1024 × 1024, all points in the preset area and all points in the bordered area may be the grids covered by the preset area or the bordered area, that is, each grid is regarded as a point, thereby ensuring that all points in the preset area, that is, the bordered area, are limited points.
In addition, since the added edge is usually a very thin line relative to the word to be processed, the first target point and the second target point are actually points near the word to be processed. Therefore, the contour point closest to the point between the two connected normals (hereinafter, the two connected normals are referred to as a "first normal" and a "second normal", respectively) is usually the contour point corresponding to the first normal or the contour point corresponding to the second normal, so that, in order to simplify the calculation of the edge-added coordinate value of the point between the first normal and the second normal, it is only necessary to calculate the distance value between the point and the contour point corresponding to the first normal and the distance value between the point and the contour point corresponding to the second normal, and take the smaller one of the calculated distance values as the edge-added coordinate value of the point between the first normal and the second normal.
In order to facilitate the calculation of the value of the bordered coordinate of all the points in the preset area and the bordered area, a specific calculation method is provided below:
sequentially collecting n contour points on the contour line, wherein the coordinates of each contour point are respectively recorded as (x)c，j，yc，j) Wherein j is more than or equal to 1 and less than or equal to n.
Then, at point (x)c，j，yc，j) Corresponding normal and point (x)c，j+1，yc，j+1) Between the corresponding normal lines, or on the two normal lines, optionally selectingTaking a point (x, y), calculating and calculating the point (x, y) to the point (x) respectivelyc，j，yc，j) And point (x)c，j+1，yc，j+1) The smaller of the two distance values is selected as the value of the bordering coordinate of the point (x, y). And calculating the value of the edge coordinate of all the points in the preset area and the edge area in sequence according to the sequence of j from 1 to n-1. In addition, the value of the edge coordinate of the point located inside the contour line may be set to a negative value, and the value of the coordinate of the point outside the contour line may be set to a positive value, thereby facilitating the distinction between the values of the edge coordinate of the point inside the contour line and the values of the edge coordinate of the point outside the contour line.
Optionally, after the sequentially connecting all the first target points to form the target boundary line of the word to be processed, the method further includes:
filling the area between the target boundary line and the contour line.
The filling of the area between the target boundary line and the contour line may be performed by assigning colors to be filled to all points in the bordered area where the bordered coordinate value is less than or equal to the target bordered value, so that the area between the target boundary line and the contour line can be filled.
In addition, multiple edges can be applied to the same character to be processed by the edge adding method, for example, it is assumed that two outer edges need to be sequentially applied to the character to be processed, wherein the edge adding width of the first outer edge is with1, and the color of the filling is color 1; the width of the added edge of the second outer edge is with2, and the color of the filling is color 2; with the relative bordered widths with respect to the text to be processed, with the lengths of 1 and 2, with1 < with 2. Before the specific edge adding, the target edge adding value d corresponding to the with1 and the with2 respectively needs to be calculatedwith1And dwith2. Specifically, after the characters to be processed are obtained, the characters to be processed are scaled according to the size of the characters to be produced, where the scaling ratio may be k, and at this time, d iswith1＝k*with1，dwith2＝k*with2。
Then according to dwith1And dwith2Determining a first target boundary line andthe specific determination process of the first target boundary line and the second target boundary line is the same as that in the above embodiment, and is not described herein again to avoid repetition. In the process, the value d of the edge coordinate of all the points between the contour line of the character to be processed and the second target boundary line is respectively determinedi。
And finally, performing color assignment on all points between the contour line of the character to be processed and the second target boundary line, wherein the specific assignment rule is as follows:
when 0 < di＜dwith1Then assign the color of the point to color 1;
when d iswith1＜di＜dwith2Then the color of the point is assigned color 2.
Thereby completing the process of adding edges to the characters to be processed.
Compared with the existing edge adding method, the word processing method has relatively less calculation amount and can be operated and realized on the mobile terminal, so that the method can be applied to a PC system and a system of the mobile terminal.
