Detailed Description
The technical solutions in the embodiments of the present invention will be described below with reference to the accompanying drawings in the embodiments of the present invention.
Referring to fig. 1, fig. 1 is a text processing method according to an embodiment of the present invention, which includes the following steps:
step S101, acquiring contour lines and a plurality of contour points of characters to be processed.
The fonts of the characters to be processed can be bitmap fonts or vector fonts. The pattern of the word to be processed can be common words or artistic words such as hollow words.
The obtaining the outline and the plurality of outline points of the text to be processed may be obtained by analyzing a font file. In particular, the font file may be a font file designed by a font designer based on a font library, the font file including a plurality of contour points and position information of the plurality of contour points. The plurality of contour points may embody contour features of the text to be processed. And analyzing the font file to obtain a plurality of contour points of the word to be processed, and determining the contour line of the word to be processed based on the plurality of contour points.
In addition, the obtaining the contour line and the plurality of contour points of the text to be processed may also be obtained by identifying the contour line of the determined text by a contour identification algorithm, so as to implement edge adding of the determined text.
And step S102, determining the normal corresponding to each contour point based on the contour line.
In this step, the normal line refers to a line that is located on a plane where the contour line is located and is perpendicular to a tangent line of the contour line, where the normal line of each contour point may be determined by taking the normal line of the contour line through each contour point. Specifically, the normal line may be obtained by first making a tangent to the contour line by each contour point and then making the corresponding tangent to each contour point perpendicular.
Step S103, determining a first target point on each normal according to a target bordering value, wherein the minimum value of the distance between the first target point and the contour line is equal to the target bordering value;
specifically, a distance calculation formula between two points may be adopted, a contour point is taken as a first point, a distance between the first point and a second point is taken as the target adding value as a constraint condition, a second point is determined on a normal line passing through the first point, at this time, if no other normal line passes through the determined second point, that is, if there is only one perpendicular line perpendicular to the contour line passing through the second point, and the perpendicular point is the first point, it is stated that the first point is a point closest to the second point in all contour points on the contour line, that is, a distance value between the second point and the first point is a minimum value between the second point and the contour line, and therefore, in this case, the determined second point may be taken as the first target point. However, when the second point is the intersection point of at least two normals, that is, at least two perpendicular lines perpendicular to the contour line can be made through the second point, the first point is only a perpendicular point of one normal line, and since the distance values from the second point to the contour line along different normals may be different, the second point has a plurality of distance values relative to the contour line, at this time, the distance values from the second point to the contour line along other normals need to be calculated, and if all other distance values are equal to or greater than the target addition value, it is indicated that the first point is still the closest point to the second point in 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, so in this case, the determined second point can be regarded 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 borderline, the determined minimum distance value between the second point and the contour line is smaller than the target borderline, so the second point cannot be used as the first target point. And if the second point on the normal line cannot be used as the first target point, a third point can be determined near the normal line, wherein the distance value between the third point and the second point is ensured to be the target bordering value, then, through the verification method, whether the distance value between the third point and the first point is the minimum distance value between the third point and the contour line is judged, if so, the third point is used as the first target point corresponding to the first point, if not, a fourth point is further determined near the normal line according to the step of determining the third point, and the 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 line.
The target edge value may be a fixed value or a relative value. For example, when the text to be processed is a bitmap font, the target bordering 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 edge appears thinner when the vector font is enlarged to a relatively larger character, and when the vector font is reduced to a relatively smaller character, the added edge appears thicker again, so that the overall appearance of the character is affected.
Step S104, all points in a target point set are sequentially connected 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 is an outer edge determined by expanding outwards based on the contour line or an inner edge determined by contracting inwards based on the contour line; and each normal line crossing the contour point comprises a symmetrical point with the same distance value as the contour point at the inner part and the outer part of the contour line, so that when the outer edge of the character to be processed is needed to be added, the target point can be determined at the outer part of the contour line; when the inner edge of the word to be processed needs to be added, the target point can be determined in the outline.
Specifically, as can be seen from the above step S103, the minimum distance between all the first target points and the contour line determined in step S103 is the target borderline, so that the determined first target points are respectively used as points in the target point set, and all the points in the target point set are sequentially connected through a smooth curve, that is, all the first target points are sequentially connected, to form a target borderline, at this time, the minimum distance between all the points on the target borderline and the contour line is regarded as the target borderline, so that the shape feature of the contour line can be better reflected by the target borderline, and the problem of poor borderline effect caused by a large difference between the shape of the determined borderline and the shape of the contour line in the prior art is solved.
Optionally, the determining the first target point on each normal according to the target edge value includes:
determining the maximum boundary line of the character to be processed according to the preset maximum edge 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 of the normal line between the contour line and a maximum boundary line, and the first target distance values are minimum values of distances between points on the normal line and the contour line;
and determining a point on the normal line, the first target distance value of which is equal to the target edge value, as the first target point.
When setting the bordering function of the text, a maximum bordering value capable of bordering is generally set for the determined text to be processed, so that a maximum borderline corresponding to the maximum bordering value can be determined by the maximum bordering value according to the method provided in the steps S101 to S104.
The preset area is a line segment which is cut on the normal line, and the line segment is a line segment of the normal line 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 determined on or near the line segment in the process of edge adding, therefore, before the edge adding, the minimum distance value (first target distance value) between each point on the line segment and the contour line can be determined first, that is, the coordinate (hereinafter referred to as "edge adding coordinate") of extending one dimension to each point on the line segment is equivalent, and the first target distance value of the point is used as the coordinate value of the extended edge adding coordinate, so that when the text to be processed needs to be added, only the points with the edge adding coordinate values equal to the target edge adding value in the preset area of all normals need to be respectively used as the first target points, and then all the first target points are sequentially connected to obtain the target boundary line.
When the point in the preset area is the intersection point of at least two normals, the coordinate value of the intersection point may be determined according to the method in step S103, and specifically, the coordinate value of the intersection point is the minimum distance between the intersection point and the contour line.
Optionally, before all points in the target point set are sequentially connected to form the target boundary line of the text to be processed, the method further includes:
determining at least one second target point between any two adjacent normals, wherein the minimum distance value in the distance values from the second target point to each contour point is equal to the target bordering value;
the second target point is taken as a point in the target point set.
Specifically, the second target point may be further determined between any two adjacent normals, where the minimum distance value of the distance value from the second target point to each of the contour points is guaranteed to be equal to the target borderline value, and since the plurality of contour points are a plurality of points extracted from the contour line and capable of representing the contour feature of the contour line, and the minimum distance value of the distance value from the second target point to each of the contour points is guaranteed to be equal to the target borderline value, the target borderline value may be regarded as the minimum distance value from the second target point to the contour line, and the second target point may be regarded as the point in which the target points are concentrated, and thus the number of points in which the target points are concentrated may be further increased, so that the target borderline 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 in a common surrounding mode is a bordered area, and the determining at least one second target point between two adjacent normal lines includes:
respectively calculating second target distance values between all points in the bordering area and the contour line, wherein the second target distance values are equal to the distance values between the points in the bordering area and the contour point with the smallest distance in the contour points;
and determining a point with a second target distance value equal to the target bordering value in the bordering area as the second target point.
Specifically, since the determined target points are all points between the contour line and the maximum boundary line in the actual edging process, and the edging coordinates of all points in the edging area can be further calculated on the basis that the edging coordinates of the points on the preset area have been determined in the above steps, when the second target point needs to be determined, all the second target points can be determined only by taking the point in the edging area, where the edging coordinate value is equal to the target edging value, as the second target point.
Since the text is usually set in a virtual grid, for example, a 1024 x 1024 grid, all the points in the preset area and all the points in the bordering area may be the respective grids covered by the preset area or the bordering area, i.e. each grid is regarded as a point, so as to ensure that all the points in the preset area, i.e. the bordering area, are limited points.
In addition, since the added edge is usually a very thin line with respect to the text to be processed, the first target point and the second target point are actually points near the text to be processed. Therefore, the contour point closest to the point between the two connected normals (hereinafter, referred to as "first normal line" and "second normal line" respectively) is usually the contour point corresponding to the first normal line or the contour point corresponding to the second normal line, so, in order to simplify the calculation process of the addition coordinate value of the point between the first normal line and the second normal line, only the distance value between the point and the contour point corresponding to the first normal line and the distance value between the point and the contour point corresponding to the second normal line need to be calculated, and a smaller value is taken as the addition coordinate value of the point between the first normal line and the second normal line from the calculated two distance values.
In order to facilitate calculation of the above-mentioned preset region and the bordering coordinate values of all points in the bordering region, a specific calculation manner is provided below:
n contour points are sequentially acquired on the contour line, wherein the coordinates of each contour point are respectively marked as (x) c，j ，y c，j ) Wherein j is more than or equal to 1 and n is more than or equal to n.
Then, at point (x c，j ，y c，j ) Corresponding normal and point (x c，j+1 ，y c，j+1 ) Between the corresponding normals or on two normals, arbitrarily selecting one point (x, y), and calculating the point (x, y) to the point (x c，j ，y c，j ) And point (x) c，j+1 ，y c，j+1 ) The smaller of the two distance values is selected as the bordering coordinate value of the point (x, y). Thus, the bordering coordinate values of all points in the preset area and the bordering area are calculated in sequence according to the sequence from 1 to n-1 of j. In addition, the coordinate value of the point inside the contour line may be set to a negative value and the coordinate value of the point outside the contour line may be set to a positive value, thereby facilitating the distinction between the coordinate value of the point inside the contour line and the coordinate value of the point outside the contour line.
Optionally, after the target boundary lines of the text to be processed are formed by sequentially connecting all the first target points, the method further includes:
and filling the area between the target boundary line and the contour line.
The filling of the region between the target boundary line and the contour line may be performed by assigning the colors to be filled to points in the bordering region where all bordering coordinate values are smaller than or equal to the target bordering value, so that the region between the target boundary line and the contour line may be filled.
In addition, a plurality of edges can be applied to the same word to be processed by the edge adding method, for example, it is assumed that two outer edges are required to be applied to the word to be processed in sequence, wherein the edge adding width of the first outer edge is width 1, and the color is color1; the width of the added edge of the outer edge of the second strip is with2, and the color of filling is color2; and the width 1 and the width 2 are relative edge widths relative to the characters to be processed, and the width 1 is less than the width 2. Before the edge is specifically added, the target edge adding value d corresponding to each of the width 1 and the width 2 needs to be calculated with1 And d with2 . Specifically, after the text to be processed is obtained, the text to be processed is scaled according to the size of the text to be produced, where the scaling ratio may be k, and at this time, d with1 ＝k*with1，d with2 ＝k*with2。
Then according to d with1 And d with2 The specific determination process of the first target boundary line and the second target boundary line is the same as that of the above embodiment, and for avoiding repetition, a detailed description is omitted herein. In the process, the addition coordinate value d of all points between the outline of the character to be processed and the second target boundary line is respectively determined i 。
And finally, carrying out color assignment on all points between the outline of the character to be processed and the second target boundary line, wherein the specific assignment rule is as follows:
when 0 < d i ＜d with1 Assigning the color of the point as color1;
when d with1 ＜d i ＜d with2 When the color of the dot is assigned color2.
Thus completing the bordering process of the word to be processed.
Compared with the existing edge method, the word processing method has relatively small calculated 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.
