Detailed Description
Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
It should be understood that the described embodiments are only some embodiments of the invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In a first aspect, embodiments of the present invention provide a method for drawing a curve, which can set a curvature of the curve more accurately.
As shown in fig. 2, a method for drawing a curve according to the present invention may include:
step 101, receiving an initial value input by a user through operating an interactive control, wherein the initial value linearly changes within a range of the interactive control according to the operation of the user on the interactive control, and a terminal value with a smaller range is greater than or equal to 0;
in this step, when the user operates the interactive control, the initial value linearly changes within the range of the interactive control according to the operating characteristics of the user on the interactive control, for example:
the interactive control may be a sliding control, and the sliding control may be a dragging bar (seekbar) as shown in fig. 1, where the dragging bar includes a progress bar and a slider, and the initial value linearly changes within a range of the progress bar according to a sliding length of the slider from the starting point in a process of dragging the slider along the progress bar by a user; i.e. the initial value, is equal to the value indicated by the position of the slider on the progress bar. For example: the range of the dragging bar is 0-1, the first moment of the sliding block is located at the starting point of the progress bar, the initial value is equal to 0 at the first moment, the length between the second moment of the sliding block and the starting point is one fourth of the length of the whole progress bar, the initial value is equal to 0.25 at the second moment, the third moment of the sliding block is located in the middle of the sliding block, and the initial value is equal to 0.5 at the third moment.
The interactive control can also be a long-press control, and the initial value linearly changes within the range of the long-press control according to the pressing time of the long-press control by the user; in this embodiment, the pressing time of the user may be accumulated, that is, when the user presses next time, the time of the previous pressing is taken as a starting point when the initial value corresponding to the pressing time of the user does not exceed the range. Of course, the pressing time of the user may not be accumulated, and in this case, the pressing time starts to be 0 every time the user presses.
The interactive control can also be a rotary control, and the initial value linearly changes within the measuring range of the rotary control according to the rotation angle of the user to the rotary control. In this embodiment, optionally, the rotation control may rotate clockwise or counterclockwise, so that the user can conveniently adjust the initial value repeatedly.
The interactive control can also be a click control, and the initial value linearly changes within the range of the click control according to the number of times of clicking the click control by the user; for example, the click control shown in fig. 3, the range of the click control may be 0 to positive infinity, the initial value may be equal to the number of clicks of the "+" symbol by the user, where the initial value is equal to 0 when the user does not click the "+" symbol, is equal to 1 when the user clicks the "+" symbol for the first time, and is equal to N when the user clicks the "+" symbol for the nth time, where N is a positive integer; as shown in fig. 3, the click control may further include a "-" symbol, and at this time, the number of times that the user clicks the click control is equal to the difference between the number of times that the user clicks the "+" symbol and the number of times that the user clicks the "-" symbol, so that the initial value may be linearly increased or decreased, which is convenient for the user to repeatedly adjust the initial value.
In this embodiment, the interactive control may be one of the above-mentioned sliding control, long-press control, spin control, and click control, may also be a combination of two or more of the above-mentioned sliding control, long-press control, spin control, and click control, and may also be other types of controls, which is not limited in this embodiment. The end point value of the interaction control with the smaller measuring range is greater than or equal to 0, for example: the range can be 0-1 mm, 0.6-1 mm, 10-1000 mm and the like, and can be set according to actual needs in practical application, and the range is not limited in the embodiment.
In an alternative embodiment of the invention, the smaller end point value of the range of the measuring range is greater than 0.
In this embodiment, since the initial value linearly increases from 0 in the measurement range when the end point value of the small measurement range is equal to 0, the radius of the circle whose radius is equal to the initial value also increases from 0, the circle expands very slowly before increasing (i.e. the speed of the circle that grows to the size desired by the user is very slow), and the curvature (degree of curvature) is very large, in some cases where curves with very large curvature are not needed, the increase is useless for the user, and the time for the user to draw the target curve is wasted, thereby reducing the user experience; therefore, in some application occasions without curves with large curvature, the end point value with the small range can be set to be a value larger than 0, so that the operation time of a user can be saved, and the user experience is improved.
In addition, under the condition that the initial value is linearly increased from 0 in the measuring range, a circle with the initial value as the radius occupies a certain measuring range in the process of being increased to the size expected by a user, so that the measuring range occupied by the other part of the initial value which is really useful for the user is smaller; therefore, setting the end point value of the small range to a value greater than 0 can increase the range occupied by the initial value really useful to the user, thereby enabling the user to set the curvature of the curve more accurately.
For example, the interactive control is a dragging bar, the dragging bar comprises a slider and a progress bar, the original measuring range of the dragging bar is 0-10 mm, and the radius range of circles used by users is 6-9 mm; in this case, when the user draws a curve each time, the user can draw a curve with a curvature close to the target curvature of the user only by dragging the slider by approximately 60% of the length of the progress bar. By the method provided by the embodiment, the range of the dragging bar can be set to be 5-10 mm, and at this time, under the condition that the length of the progress bar is not changed, a user can draw a satisfactory curve only after dragging the slider by 10% of the length of the progress bar.
And after the user drags the slider to the vicinity of the target position, the user often needs to adjust the slider back and forth to select the most satisfactory curve, and at this time, under the condition that the length of the progress bar is unchanged and the distance for the user to slide the slider is the same, the change amount of the initial value set by the dragging bar with the length range of 5-10 mm is smaller than the change amount of the initial value set by the dragging bar with the length range of 0-10 mm, which means that the user can more accurately set the curvature of the curve by the dragging bar with the length range of 5-10 mm compared with the dragging bar with the length range of 0-10 mm.
Step 102, when the initial value is located in a first interval of the range, performing a first adjustment on the initial value to obtain an adjustment value, wherein when the initial value increases in the first interval, the adjustment value increases with the increase of the initial value, and the increase of the adjustment value is smaller than the increase of the initial value;
in this step, any two initial values in the first interval are taken, and the difference between two adjustment values corresponding to the two initial values is smaller than the difference between the two initial values. This means that, compared to the prior art method in which the initial value is directly used as the radius of the target circle, the radius increase speed of the circle with the adjustment value as the radius is reduced under the condition that the operation characteristics of the user on the interactive control are the same. Therefore, when the user operates the interactive control in the first interval, the curvature of the curve can be set more accurately.
Since the curvature of the circle directly using the initial value as the radius changes faster in the first half of the range and slower in the second half when the initial value linearly increases in the range, in an optional implementation manner of this embodiment, the first interval may be located in the first half or the middle of the range, so that the curvature of the curve drawn in the subsequent step changes more uniformly in the entire range.
Of course, in some applications where a curve with no need for a large degree of curvature is desired, the first interval may also be located in the middle-second half of the range. For example, as shown in the coordinate system shown in fig. 4, the horizontal axis represents the range of the interactive control, and the range of the range is 0-1 mm; the vertical axis represents the target radius in the subsequent step; the first interval is positioned in the middle and the rear half of the measuring range, and the initial value positioned in the first interval is sleeved with a formula 1- (1-x)3Then (x represents an initial value), obtaining an adjustment value; the straight line in the coordinate system represents the initial value and the curve represents the adjustment value. As can be seen from fig. 4, in the first interval, when the operation characteristics of the interactive control by the user are the same, the increase of the adjustment value is smaller than the increase of the initial value, so that when the user operates the interactive control in the first interval, the adjustment value is used as the target radius, and the curvature of the curve can be set more accurately.
Optionally, the ratio of the first interval in the measuring range is greater than a preset threshold.
In this embodiment, the larger the proportion of the first interval in the measuring range is, the wider the range in which the curvature can be accurately adjusted by the user is, and the better the user experience is. The preset threshold value can be 0.3, 0.5, 0.6, 0.8, 1 and the like, and can also be other values between 0 and 1.
Optionally, in the above embodiment, the first interval may be the same as the range of the measuring range. At this moment, when the user operates in the whole range of the interactive control, the curvature of the curve can be set more accurately.
Optionally, the range of the interactive control may further include a second interval, and when the initial value is located in the second interval of the range, the initial value is second adjusted to obtain an adjustment value, where when the initial value increases in the second interval, the adjustment value increases with the increase of the initial value, and an increase of the adjustment value is greater than an increase of the initial value.
In this embodiment, any two initial values in the second interval are taken, and the difference between the two adjustment values corresponding to the two initial values is greater than the difference between the two initial values. This means that, compared to the prior art method in which the initial value is directly used as the radius of the circle in the subsequent step, the increase speed of the radius of the circle with the adjustment value as the radius is increased under the condition that the operation characteristics of the user on the interactive control are the same. In this way, when the user operates the interactive control in the second interval, the target circle generated in the subsequent step can grow faster.
As shown in fig. 4, as an optional implementation manner of the foregoing embodiment, the endpoint value with the larger second interval is equal to the endpoint value with the smaller first interval, and the adjustment value corresponding to the initial value in the first interval is greater than or equal to the adjustment value corresponding to the initial value in the second interval. In this case, when the second interval and the first interval constitute a continuous interval and the initial value linearly increases in the continuous interval, the adjustment value increases as the initial value increases. Therefore, in some application occasions without curves with large curvature, the target circle can be quickly unfolded into a circle with a size expected by a user, and then the curvature of the target circle is accurately adjusted in the first interval, so that the user experience is improved.
As another optional implementation manner of the foregoing embodiment, the end point value with the smaller second interval is equal to the end point value with the larger first interval, and the adjustment value corresponding to the initial value in the first interval is smaller than or equal to the adjustment value corresponding to the initial value in the second interval. In this case, the first interval and the second interval constitute a continuous interval, and when the initial value linearly increases in the continuous interval, the adjustment value increases as the initial value increases. Therefore, when the value of the initial value is large, the curvature change of the circle with the initial value as the radius is not obvious, and therefore, the method adopted by the embodiment can accelerate the curvature change of the target circle generated in the subsequent steps when the user operates at the rear section of the interactive control, and the user experience is improved.
Optionally, as shown in fig. 5 (a straight line in the figure represents an initial value, and a curve represents an adjustment value), the two embodiments may also be combined, so that when the initial value linearly increases in the range of the interactive control, the adjustment value that changes with the initial value first increases rapidly, then increases slowly, and finally increases rapidly.
Step 103, drawing a target circle by taking the adjustment value as a target radius;
in this embodiment, in the process that the adjustment value changes with the initial value, the target circle drawn with the adjustment value as the target radius also changes dynamically with the adjustment value. Alternatively, the target circles may be expanded with the center of the circle as a base point (i.e., the centers of the target circles coincide) or may be expanded with a certain point on the circumference as a base point, for example, as shown in fig. 1, the lowest end point on the circumference is expanded as a base point. Of course, the expansion can be performed in other manners, which is not limited in this embodiment.
Optionally, the drawing a target circle by using the adjustment value as a target radius may include: scaling the adjustment value according to a linear scaling coefficient to obtain a target radius; and drawing a target circle according to the target radius.
In this embodiment, when the adjustment value obtained in step 102 is smaller and does not match the size of the electronic device, a linear scaling coefficient larger than 1 may be set, and the adjustment value and the linear scaling coefficient are multiplied to obtain a target radius suitable for the size of the electronic device. For the same reason, when the adjustment value obtained in step 102 is larger, a linear scaling coefficient smaller than 1 may be set, and the adjustment value and the linear scaling coefficient are multiplied to obtain the target radius.
And 104, cutting the target circle by using the cutting frame to generate a target curve.
In this step, the trimming frame may be specified by a user, or may be generated according to a preset rule, for example, as shown in fig. 6, in an optional implementation manner of this embodiment, the target curve may be used as an arrangement path of a text in the text box, so that the whole text in the text box has a special bending effect; at this time, when the user inputs the text box, a cutting box adapted to the text box may be generated.
In the above embodiment, the user may input the text box before step 101, in which case, the size of the trimming box may be the same as the text box, and the arrangement position may coincide with the text box. In this way, as shown in fig. 1, when the target circle is drawn in step 102, the target circle may be drawn with the midpoint of the lower frame of the trimming frame as the lower endpoint of the target circle. And after the target circle is generated, cutting the target circle by using the cutting frame, and taking a curve positioned in the cutting frame as a target curve.
After the target curve is generated, the target curve is used as a layout path, and texts in the text box are uniformly arranged along the layout path, so that the texts in the text box have a special bending effect on the whole. Optionally, when the target curve is used as a layout path of a text, the target curve may be set to be transparent, so that the target curve does not affect the display effect of the text.
Of course, when the target curve is applied to other situations, the trimming frame may also be generated according to other manners, and after the trimming frame is generated, the user may also perform operations such as scaling, moving, rotating, and the like on the trimming frame, which is not limited in this embodiment; in the same way, the generation sequence between the trimming frame and the target circle is not limited in this embodiment, and may be set according to actual needs.
Optionally, the range of the interactive control may be dynamically changed along with the size of the trimming frame. For example: the end point value with the smaller measuring range is positively correlated with the width and/or height of the cutting frame; thus, when the cropping frame is enlarged, the smaller end point value of the interactive control is enlarged, so that a target circle with an initial radius positively correlated with the smaller end point value is adapted to the size of the cropping frame; in the same way, the end point value with the larger measuring range can also be positively correlated with the width and/or the height of the cutting frame, so that when the cutting frame becomes large, the end point value with the larger interaction control also becomes large, and the maximum radius and the target circle with the positive correlation of the end point value are adapted to the size of the cutting frame.
In the method for drawing a curve provided by this embodiment, an initial value input by a user through operating an interactive control is received, where the initial value linearly changes within a range of the interactive control according to the operation of the user on the interactive control, and a terminal value of the interactive control with a smaller range is greater than or equal to 0; when the initial value is located in a first interval of the range, performing first adjustment on the initial value to obtain an adjustment value, wherein when the initial value is increased in the first interval, the adjustment value is increased along with the increase of the initial value, and the increase of the adjustment value is smaller than that of the initial value; drawing a target circle by taking the adjustment value as a target radius; and cutting the target circle by using the cutting frame to generate a target curve. In this way, compared with the method in the prior art in which the initial value is directly used as the radius of the target circle, when the user operates the interactive control in the first interval under the condition that the operating characteristics of the user on the interactive control are the same, the curvature of the curve can be set more accurately by using the adjustment value as the radius of the target circle.
