For example, when the user selects the dotted line type, the dotted line can be drawn according to the dotted line type, the line segment starting point and the line segment ending point.
The following are detailed below. It should be noted that the description sequence of the following embodiments is not intended to limit the priority sequence of the embodiments.
Referring to fig. 2, fig. 2 is a schematic flow chart illustrating a line segment drawing method according to an embodiment of the present disclosure. The specific flow of the line segment drawing method can be as follows:
101. and acquiring the type of the target line segment according to the selection operation of the user.
The line segment type refers to a kind of a line segment, wherein in the embodiment of the present application, the line segment type may include a dotted line or a solid line, and the like.
After the user selects the type of the line segment to be drawn, the target line segment type is acquired according to the selection of the user.
In this embodiment of the present application, a user may implement obtaining each line segment type through a graphical identifier corresponding to a line segment type provided in a terminal interface, that is, optionally, in some embodiments of the present application, before the step "obtaining a target line segment type according to a selection operation of the user", the method further includes:
receiving a starting instruction of a user for a target tool;
responding to the starting instruction, and displaying a plurality of graphic identifications in a target area;
in this embodiment of the present application, each graph identifier corresponds to one line segment type, for example, the dashed line identifier corresponds to the dashed line type, and the solid line identifier corresponds to the solid line type.
In this embodiment of the present application, the tool refers to a device capable of drawing a line segment or an application installed in the device, where the device may include an electronic whiteboard, and the application may include a drawing program (APP), and the application displays a graphical identifier corresponding to each line segment type in a target area through starting the device or starting a corresponding application, so as to facilitate selection of the graphical identifier by a user.
In the embodiment of the application, the target area may include a terminal interface, and the user may select the line segment type of the line segment to be drawn as needed by displaying the graphic identifier corresponding to each line segment type on the terminal interface.
In some embodiments of the present application, the step "obtaining a target line segment type according to a selection operation of a user" includes:
acquiring a target line segment type according to the selection operation of a user for the target graphic identifier;
after the user selects the target graphic identifier from the graphic identifiers according to the requirement, the type of the target line segment can be determined according to the target graphic identifier selected by the user. For example, after the user selects a desired target graphic identifier from a plurality of graphic identifiers displayed on the terminal interface, the line segment type corresponding to the target graphic identifier may be used as the target line segment type.
102. And determining a line segment starting point and a line segment end point according to the sliding operation of the user.
The positioning of the starting point and the ending point of the line segment can be realized through the sliding operation of a user. For example, in the embodiment of the present application, after the user slides on the screen according to the desired position of the line segment, the start point and the end point of the line segment can be determined by the position of the contact point during the sliding operation of the user.
In this embodiment of the present application, the line segment starting point and the line segment ending point may be determined according to the touch time of each touch point, that is, optionally, in some embodiments of the present application, the step "determining the line segment starting point and the line segment ending point according to the sliding operation of the user" includes:
recording the touch time of each contact in the sliding operation process of a user;
taking the contact point with the minimum touch time as a starting point of the line segment;
and taking the touch point with the largest touch time as the line segment terminal point.
The touch time reflects the contact time of a user with each contact in the interface, wherein the contact time of each contact in the sliding operation process is in sequence, the contact with the previous touch time often meets the requirement of the user on the starting point of the line segment, and similarly, the contact with the later touch time meets the requirement of the user on the ending point of the line segment.
The touch point with the minimum touch time is used as the starting point of the line segment, and the touch point with the later touch time is used as the ending point of the line segment, so that the use habit of the user is better met.
In the embodiment of the present application, the starting point and the ending point of the line segment function to determine a line segment according to two position points, and therefore, in the embodiment of the present application, the starting point of the line segment may also be understood as the ending point of the line segment, and similarly, the ending point of the line segment may also be understood as the starting point of the line segment.
In the embodiment of the present application, since the touch time of the user for the touch point in the sliding operation process is continuously increased, the touch point with the later touch time may be used as the line segment end point. For example, after the user performs a sliding operation on the interface, if the touch point with the later touch time is taken as the line segment end point, there is an inaccurate condition, and therefore, in this embodiment of the present application, the line segment end point may be determined according to the interval of the touch times, for example, a difference value between adjacent touch times may be calculated, and whether the line segment end point is a touch point with the earlier touch time or a touch point with the later touch time is determined according to the difference value, that is, optionally, in some embodiments of the present application, the step "take the touch point with the largest touch time as the line segment end point" includes:
and when the difference value of the adjacent touch time is larger than a preset threshold value, taking the touch point with the previous touch time as the segment terminal point.
If the difference between the adjacent touch times is larger, it indicates that the time difference between the touch time of the next touch point and the touch time of the previous touch point is larger, and the touch time of the next touch point and the touch time of the previous touch point are more consistent with the re-touch with the interface after the user finishes the sliding operation.
Correspondingly, when the difference between the adjacent touch times is within the preset threshold, the touch point with the later touch time may still be used as the segment end point, for example, the user slides the finger slowly and slides continuously, in view of this situation, the touch point with the largest touch time may be used as the segment end point, or, when the user separates from the interface and then touches the interface quickly, in view of this situation, it may be considered that the user is unsatisfied with the position of the segment end point, and needs to adjust the segment end point, therefore, when the difference between the time when the user touches the interface again and the time when the user separates the finger from the interface last time is within the preset threshold, the touch point with the later touch time may be used as the segment end point.
In this embodiment of the present application, after the user selects the graphic identifier corresponding to the line segment type, a drawing interface may be provided for the user, so that the user can slide the drawing line in the drawing interface, that is, optionally, in some embodiments of the present application, the step "determining the starting point and the ending point of the line segment according to the sliding operation of the user" includes:
after the selection operation is completed, providing a target drawing interface for the user;
and determining a line segment starting point and a line segment end point according to the sliding operation of the user in the target drawing interface.
The drawing interface is provided, so that a user can conveniently perform finger sliding operation in the drawing interface, and further line segments are drawn and presented.
103. And drawing a target line segment according to the type of the target line segment, the starting point of the line segment and the end point of the line segment.
A line segment can be determined according to the type of the line segment, the starting point of the line segment and the end point of the line segment, so that the line segment can be drawn according to the type of the line segment, the starting point of the line segment and the end point of the line segment.
In this embodiment of the present application, for the drawing of a line segment, a manner of splicing a plurality of line segments may be adopted to implement the drawing of a final line segment, for example, by splicing a plurality of line segments back and forth, that is, optionally, in some embodiments of the present application, the step "drawing a target line segment according to the type of the target line segment, the starting point of the line segment, and the ending point of the line segment" includes:
determining a reference line segment according to the type of the target line segment, and determining the reference length of the reference line segment according to preset parameters;
determining a target line segment distance according to the line segment starting point and the line segment end point;
determining the number of reference line segments according to the target line segment distance and the reference length;
and splicing the reference line segments with the reference line segment number to obtain a target line segment.
In this embodiment, the reference line segment is a component of the target line segment, for example, in this embodiment, when the target line segment is a solid line, the reference line segment is also a solid line, and when the target line segment is a dotted line, the reference line segment may be a segment formed by splicing the solid line and a white line. And the target line segment is drawn by splicing a plurality of sections of reference line segments.
In the embodiment of the present application, the reference length of the reference line segment may be determined according to a setting of a user, for example, the user sets a parameter of the reference line segment according to a requirement, and sets a parameter such as a length, a width, and the like of the reference line segment.
The number of reference line segments required for drawing the line segment can be calculated through the reference length of the reference line segment and the distance of the target line segment, and the drawing of the target line segment is realized through the splicing of the reference line segments of the reference line segment number, for example, when the distance of the target line segment is 10cm and the reference length of the reference line segment is 1cm, the target line segment can be obtained through the splicing of ten reference line segments.
In the line segment drawing process, the reference line segments may be spliced according to the deviation angle between the line segment start point and the line segment end point, that is, optionally, in some embodiments of the present application, the step "splicing the reference line segments of the reference line segment number to obtain the target line segment" includes:
determining a line segment offset angle according to the line segment starting point and the line segment end point;
and splicing the reference line segments with the reference line segment quantity according to the line segment deviation angle to obtain a target line segment.
The line segment can be drawn by calculating the offset angle of the line segment according to the line segment starting point and the line segment end point and splicing a plurality of reference line segments according to the line segment offset angle.
In this embodiment, the target line segment type may include a dotted line type, and therefore, the target line segment may include a target dotted line, and correspondingly, for the dotted line, the reference line segment may include a half-round solid line and a half-round blank line, where the half-round solid line and the half-round blank line are spliced back and forth to form the reference line segment.
In some embodiments of the present application, the step "splicing the reference line segments of the reference line segments to obtain the target line segment" includes:
and splicing the reference line segments with the reference line segment number to obtain a target dotted line.
And the drawing of the dotted line is realized by splicing the reference line segments formed by splicing the half-wheel solid lines and the half-wheel blank lines in the front and back manner.
In the process of drawing the target line segment, the offset angle of each reference line segment can be adjusted to be the line segment offset angle, so that the target line segment can be accurately drawn.
In this embodiment of the present application, when the user slides in the interface, the line segment may be dynamically drawn along with the movement of the user's finger, that is, optionally, in some embodiments of the present application, the step "drawing the target line segment according to the target line segment type, the line segment start point, and the line segment end point" includes:
and when the line segment end point is updated, drawing a target line segment according to the type of the target line segment, the line segment start point and the updated line segment end point.
The position of the line segment end point is continuously updated along with the sliding of a user in the terminal interface, wherein the target line segment is respectively constructed through the dynamically changed line segment end point, so that the terminal interface can present a situation that the line segment continuously changes along with the movement of a user finger.
The method and the device for drawing the line segment comprise the steps of obtaining the line segment type according to selection operation of a user, determining a line segment starting point and a line segment ending point according to sliding operation of the user, and drawing the line segment according to the line segment type, the line segment starting point and the line segment ending point. The line segment can be drawn according to the line segment type, the line segment starting point and the line segment terminal point through the determination of the line segment starting point and the line segment terminal point after the user selects the line segment type and the sliding operation. For example, when the user selects the dotted line type, the dotted line can be drawn according to the dotted line type, the line segment starting point and the line segment ending point. The line segment drawing function is provided, so that the office function of the product is improved, and the convenience is improved.
Referring to fig. 3, fig. 3 is a schematic flow chart illustrating a user operation and a line segment drawing according to an embodiment of the present application, where the flow specifically includes:
111. selecting a line segment type by a user through a graphic identifier provided on the terminal equipment;
112. after the type of the online segment is determined, the terminal equipment provides a drawing interface for a user;
113. in a drawing interface, a user presses a finger and records to obtain a line segment starting point;
114. acquiring a segment end point along with the movement of the finger of the user, and calculating a segment offset angle according to the segment start point and the segment end point;
115. and drawing the line segment according to the line segment type, the line segment starting point, the line segment end point and the line segment offset angle.
The terminal device provides the graphic identification for the user and provides the drawing interface for the user after the user selects the graphic identification, so that the user can draw the line segment through the drawing interface.
The positioning of the line segment end point and the line segment starting point is realized through the sliding of the finger of a user in the drawing interface, and the line segment can be drawn according to the line segment type, the line segment starting point and the line segment end point.
In the embodiment of the application, the line segment deviation angle is calculated through the line segment starting point and the line segment end point, so that the line segment can be drawn according to the line segment deviation angle, and the accuracy of line segment drawing is improved.
Referring to fig. 4, fig. 4 is a schematic flow chart of drawing a dotted line according to an embodiment of the present application, where the specific flow of drawing the dotted line includes:
121. selecting a dotted line (including selecting a dotted line type through a graphic identifier of an interface) by a user, determining a reference line segment according to the dotted line, and setting parameters of the reference line segment according to the user to obtain the reference length of the reference line segment;
122. pressing a finger in a drawing interface by a user to obtain a segment starting point;
123. obtaining a line segment terminal point along with the sliding of the finger of the user in the drawing interface, and obtaining a line segment offset angle according to the line segment starting point and the line segment terminal point;
124. obtaining a line segment distance according to the line segment starting point and the line segment end point, and obtaining the number of reference line segments according to the line segment distance and the reference length;
125. judging whether the number of the reference line segments is greater than a preset threshold value, and executing a step 126 when the number of the reference line segments is greater than the preset threshold value; when the number of the reference line segments is smaller than the preset threshold, executing step 127;
126. splicing the reference line segments with the reference line segment number to draw a dotted line;
127. re-determining the line segment end point and the line segment offset angle according to the movement of the finger of the user, and re-drawing the dotted line according to the new line segment end point and the line segment offset angle;
128. and (6) ending.
When the user selects the dotted line, the user is indicated to desire to draw the dotted line, and correspondingly, the corresponding reference line segment can be determined according to the dotted line, wherein the determination of the starting point, the ending point and the deviation angle of the line segment is realized according to the sliding of the finger of the user in the drawing interface, and the dotted line is further drawn according to the starting point, the ending point, the deviation angle and the reference line segment.
The position of the line segment end point is continuously changed along with the continuous movement of the finger of the user, correspondingly, the drawing of the dotted line with the continuously changed offset angle can be realized according to the dynamically changed line segment end point and the corresponding line segment offset angle until the user stops the movement of the finger, and the final positioning and drawing of the dotted line are completed.
In the embodiment of the present application, by splicing a reference line segment, i.e., a line segment, with a line segment spliced by a solid line and a margin line, a solid line can be drawn to a dotted line.
In the embodiment of the present application, the dotted lines are obtained by splicing the reference line segments, and the line segment offset angle of each reference line segment is also consistent with the line segment offset angle of the final dotted line in the process of drawing the dotted lines, so the offset angle of the dotted line can be calculated according to the offset angle of each reference line segment.
In the embodiment of the present application, the offset angle of the reference line segment may be calculated by coordinate values of any two different points in the reference line segment, for example, by calculating arctangent values of the two points, the line segment offset angle of the reference line segment is obtained according to the arctangent values.
In the embodiment of the present application, when a finger of a user slides on a drawing interface, a distance between a line segment start point and a line segment end point can be obtained according to coordinates of the line segment start point and the line segment end point, and a number requirement of reference line segments can be obtained through an operation of the distance and a reference length of a reference line segment.
In the embodiment of the present application, the length of the dotted line to be drawn may be determined by determining whether the number of the reference line segments is greater than a preset threshold, for example, when the preset threshold is zero, and when the number of the reference line segments is less than zero, it indicates that the length of the dotted line to be drawn is less than the reference length, it may be understood that the length of the dotted line to be drawn is short, and when the number of the reference line segments is greater than zero, it indicates that the dotted line needs to be drawn by splicing at least one reference line segment.
In the embodiment of the present application, when the number of the reference line segments is smaller than the preset threshold, it indicates that the line segment end point of the dotted line to be drawn is not finally determined, so that the reference line segments can be spliced after the fingers of the user move further, that is, the line segment end point is further determined, that is, when the number of the reference line segments is smaller than the preset threshold, the calculation of the offset angle of the dotted line segments is performed first, and the dotted line is not specifically drawn, thereby saving the complexity of the operation of drawing the dotted line.
In the embodiment of the present application, for the drawing of a line segment, it may be understood that contacts (e.g., pixels on an electronic screen) on a connection line formed by a line segment offset angle are sequentially connected, for example, for a line segment (e.g., a horizontal line segment) with a zero line segment offset angle, an abscissa value of a next contact is a sum of an abscissa value of a previous contact and a line segment width, and an ordinate of a next contact is an ordinate of a previous contact, the positioning of each contact may be achieved by determining coordinates of each contact, and then the line segment may be drawn by connecting each contact through coordinates, where for a line segment in a non-horizontal direction, coordinates of the next contact may be calculated through the line segment offset angle and the coordinate value of the previous contact.
In the embodiment of the present application, for the drawing of a line segment in an electronic whiteboard, the line segment may be drawn by adjusting the pixel values of corresponding touch points, for example, a plurality of pixel points on the line segment are determined according to a starting point and an ending point of the line segment, and the line segment may be drawn by uniformly adjusting the pixel values of the plurality of pixel points, for example, in a reference line segment splicing process, the pixel values of corresponding pixel points may be uniformly adjusted according to the length of each reference line segment, so as to draw the line segment in the electronic whiteboard, where parameters such as the color and thickness of the line segment may be determined according to user predefinition.
In the embodiment of the present application, for the drawing of the dotted line, the characteristic of the dotted line may also be embodied in a manner of appending a reference line segment to the end of the line segment, for example, when the dotted line is spliced after the drawing, and the end of the dotted line is a half round of blank line, the characteristic that the last part of the original dotted line is the blank line may be embodied in a manner of splicing a reference line segment at the end of the dotted line again, so as to avoid that the user cannot visually observe the last blank line of the original dotted line. In the embodiment of the application, the half-wheel solid line can be spliced again only at the tail of the original dotted line, so that the number of spliced line segments is reduced, and the drawing complexity is reduced.
