In order to avoid the defect that the method for realizing the animation effect in the related technology is complex, the method for processing the animation is provided, after the initial value of the dotted line attribute of the object is determined, the dotted line attribute value of the object is adjusted successively according to the determined initial value of the dotted line attribute and a preset adjustment strategy, after each adjustment, the object is redrawn according to the adjusted dotted line attribute value, and because the objects drawn each time have differences gradually, the animation effect can be realized, so that the animation effect can be realized only by adjusting the dotted line attribute value, and the realization is easy.
As shown in fig. 1A, fig. 1A is a flowchart of an embodiment of an animation processing method of the present application, including the following steps:
in step 101, an initial value of a dashed line attribute of an object is determined, where the object is a graph composed of at least one line, and the dashed line attribute includes a real line segment length attribute and a space length attribute between two solid line segments.
In step 102, the dashed line attribute value of the object is adjusted successively according to the determined dashed line attribute initial value and a preset adjustment strategy, and after each adjustment, the object is redrawn according to the adjusted dashed line attribute value.
The application can be applied to electronic equipment with drawing tools. The electronic device may be a handheld electronic device or other electronic device. For example, it may be a mobile phone, or a slightly smaller portable device such as a wristwatch device, pendant device, or other wearable or miniaturized device, but also a tablet computer, notebook computer, desktop computer, television, computer integrated into a computer display, or other electronic equipment. In the present application, the drawing tool is a drawing tool supporting setting of a dotted line style.
In step 101, the object may be an object drawn in real time by a drawing tool or may be a previously drawn object. For example, the object may be rendered before determining the initial value of the dashed attribute of the object. For another example, a rendered object may be obtained before determining the initial value of the dashed attribute of the object.
The object is a graph formed by at least one line, namely the object is formed by the lines, and at least one line is arranged in the lines forming the graph. The lines constituting the pattern may be either solid lines or broken lines. As shown in fig. 1B, fig. 1B is a schematic diagram of an object shown in the present application. In the schematic diagram, the object may be a graph composed of one solid line, a graph composed of a plurality of broken lines, or a graph composed of a plurality of solid lines.
The dashed lines are broken lines drawn as short lines. The dashed line has a dashed line attribute that includes a solid line end length attribute and a space length attribute between two solid line segments. The space length attribute between two solid line segments may also be referred to as a null line length attribute. In the dashed lines, the different dashed lines are distinguished by the attribute values in the dashed line attributes. In an example, the real-line-segment length attribute value in the dotted-line attribute may be the number of pixels in the real line segment, and the interval-length attribute value in the dotted-line attribute may be the number of interval pixels between two solid-line segments.
The method comprises the steps of firstly determining an initial value of a dotted line attribute of an object. There are many ways to determine the initial value of the dashed attribute of the object, and the present disclosure illustrates several of these ways.
In an alternative implementation, the current dotted-line attribute value of the object is directly determined as the initial value of the dotted-line attribute of the object.
In the case that the line composing the object is a dotted line, the object has a dotted line attribute value, and the dotted line attribute value is directly determined as the initial value of the dotted line attribute of the object, that is, the current state of the object is directly used as the initial state of the adjustment.
In another optional implementation manner, the initial value of the dotted-line attribute of the object is set according to the received attribute setting instruction.
Wherein the attribute setting instruction is an instruction to set a dotted attribute value. For example, the attribute setting instruction may be a setting instruction directly triggered by the user. For another example, the attribute setting instruction may be a setting instruction that is triggered in the case where the animation processing condition is satisfied.
In one example, the attribute setting instructions may indicate both that attribute values need to be set and how to set the attribute values.
For example, an attribute setting instruction is received, and the initial value of the dotted-line attribute of the object is set according to a setting target value carried in the attribute setting instruction.
The set target value may be an attribute value input by a user, and the initial value of the dotted-line attribute of the object is set according to the attribute value input by the user, so that controllability of the initial value of the dotted-line attribute is achieved.
In addition, the attribute setting instruction may indicate how to set the attribute value in another manner, for example, the attribute setting instruction may also carry an identifier indicating an initial value of the dotted-line attribute, and the initial value of the dotted-line attribute of the object is set according to the identifier.
In another example, an attribute setting instruction is received, and an initial value of the dotted-line attribute of the object is set according to a preset setting target value.
In this example, at least one setting target value may be set in advance, and the initial value of the dotted-line attribute of the object is set directly according to the preset setting target value when the attribute setting instruction is received.
Therefore, the initial value of the dotted line attribute of the object can be set according to the preset set target value, user input is not needed, and user experience is improved.
It can be understood that, according to the received attribute setting instruction, after the initial value of the dotted-line attribute of the object is set, the object may be redrawn.
Based on the above embodiments, the present application separately introduces the cases where the lines constituting the object are broken lines and solid lines.
For the case where the line constituting the object is a dotted line, the object currently has a dotted line attribute value, but in order to achieve a certain animation effect, the dotted line attribute value of the object may be changed according to the animation effect that needs to be achieved. For example, to achieve the effect of gradually displaying the object, the dotted-line attribute value of the object may be reset to be set to the dotted-line attribute initial value, where the interval-length attribute initial value is greater than the real-line-segment-length attribute initial value. For another example, to achieve the effect of gradually disappearing the object, the dashed attribute value of the object may be reset and set to the dashed attribute initial value, where the interval length attribute initial value in the dashed attribute initial value is smaller than the real line segment length attribute initial value.
The difference value between the initial value of the interval length attribute and the initial value of the real line segment length attribute is related to the animation display effect. For example, if the effect of gradually displaying the object is an animation display effect from nothing, the interval length attribute initial value is set to a value much larger than the real line length attribute initial value, for example, the real line length attribute initial value may be 0, and the interval length attribute initial value may be 1000. For another example, when the effect of gradually displaying the object is an animation display effect from a hidden display to a clear display, the interval length attribute initial value is set to a value slightly larger than the real line length attribute initial value, for example, the real line length attribute initial value may be 1, and the interval length attribute initial value may be 20.
In an example, the difference between the initial value of the interval length attribute and the initial value of the real-line length attribute may be a difference defined by the animation effect displayed by the user as needed, or a difference determined by the machine according to the input animation effect, and is not limited specifically.
In the case where the line constituting the object is a solid line, the object may have a dotted-line attribute, but the dotted-line attribute has no effective value, and based on this, it is necessary to set an initial value of the dotted-line attribute of the object so that the solid line constituting the object is changed to a dotted line. In one example, the initial value of the dotted-line attribute of the object may be set according to the received attribute setting instruction. The above examples have been introduced, and are not described in detail herein.
Regarding step 102, the dashed attribute value of the object may be adjusted successively according to the determined initial value of the dashed attribute and a preset adjustment policy, and after each adjustment, the object may be redrawn according to the adjusted dashed attribute value.
The preset adjusting strategy is a preset strategy for adjusting the dotted line attribute value of the object so as to enable the object to have an animation effect. For example, the dotted-line attribute value of the object may be adjusted successively according to a preset adjustment amplitude value. The adjustment amplitude value of each adjustment can be the same or different, and the adjustment amplitude value can be determined according to the animation effect, or can be an amplitude value generated randomly each time. The adjustment frequency may also be set in a preset adjustment strategy. Since the adjustment is performed one by one, and the object is redrawn according to the adjusted dotted-line attribute value after each adjustment, the object drawn each time may be different, and thus an animation effect can be achieved.
The successive adjustment of the dotted line attribute value of the object may be performed by successively adjusting the real line length attribute of the object, by successively adjusting the interval length attribute value of the object, by successively adjusting the real line length attribute and the interval length attribute value of the object at the same time, or by adjusting the real line length attribute of the object at one time and the interval length attribute value of the object at the next time during the adjustment, and the adjustment is performed cyclically in sequence.
In an alternative implementation, in a case where the animation effect of the object is an effect of gradually displaying the object, an interval length attribute initial value of the broken line attribute initial values is larger than a real line segment length attribute initial value.
The step of successively adjusting the dotted line attribute value of the object according to the determined dotted line attribute initial value and a preset adjustment strategy at least comprises one of the following steps:
successively increasing the real line segment length attribute value in the dotted line attribute value of the object according to a first preset amplitude value by taking the determined real line segment length attribute initial value as a starting point;
and gradually reducing the interval length attribute value in the dotted line attribute value of the object according to a second preset amplitude value by taking the determined interval length attribute initial value as a starting point.
In order to achieve the effect of gradually displaying the object, of the broken-line attribute initial values, the interval-length attribute initial value may be set larger than the real-line-segment-length attribute initial value.
In one example, after determining the initial value of the dashed-line attribute, the real-line-length attribute value of the dashed-line attribute values of the object may be successively increased by a first preset amplitude value with the determined initial value of the real-line-length attribute as a starting point, so as to gradually reduce the difference between the real-line-length attribute value and the interval-length attribute value. The successively increasing of the real-line segment length attribute value in the dashed-line attribute value of the object may be increasing a first preset amplitude value every time adjustment is performed according to a preset adjustment frequency, with the determined real-line segment length attribute initial value as a starting point.
Wherein, the reduction range can be set according to the animation effect. The first preset amplitude value increased in each adjustment may be the same or different.
Assuming that the initial value of the dotted line attribute is set to [0,1000], at this time, the object is invisible, in each adjustment, the real line segment length attribute value in the dotted line attribute value of the object is increased by a first preset amplitude value of 5, the dotted line attribute value after the first adjustment is [5, 1000], the object is drawn according to the adjusted dotted line attribute value, the dotted line attribute value after the second adjustment is [10, 1000], the object is drawn according to the adjusted dotted line attribute value, and so on, and the animation effect of realizing the object can be obtained.
Therefore, in this embodiment, the difference between the real-line length attribute value and the interval length attribute value can be gradually reduced by gradually increasing the real-line length attribute value, so as to gradually display the animation effect of the object.
After the initial value of the dotted line attribute is determined, the determined initial value of the interval length attribute may also be used as a starting point, and the interval length attribute value in the dotted line attribute value of the object is gradually reduced according to a second preset amplitude value, so as to gradually reduce the difference between the real line segment length attribute value and the interval length attribute value. The step of successively decreasing the interval length attribute value in the dotted line attribute value of the object may be to subtract a second preset amplitude value every time of adjustment according to a preset adjustment frequency, with the determined interval length attribute initial value as a starting point.
In each adjustment, the reduced second preset amplitude value may be the same or different. To finally be able to display the object, the real line segment length attribute initial value is not equal to 0.
Assuming that the initial value of the dotted line attribute is set to [20,1000], because the difference between the real line segment length attribute value and the interval length attribute value is too large, the object is invisible, in each adjustment, the interval length attribute value in the object dotted line attribute value is reduced by a second preset amplitude value of 2, the dotted line attribute value after the first adjustment is [10, 998], the object is drawn according to the adjusted dotted line attribute value, the dotted line attribute value after the second adjustment is [10, 996], the object is drawn according to the adjusted dotted line attribute value, and so on, so that the animation effect of realizing the object can be obtained.
Therefore, in this embodiment, the difference between the real-line segment length attribute value and the interval length attribute value can be gradually reduced by gradually reducing the interval length attribute value, so as to gradually display the animation effect of the object.
In an example, after determining the initial value of the dashed-line attribute, the determined initial value of the real-line-segment length attribute may be used as a starting point, and the real-line-segment length attribute value in the dashed-line attribute values of the object may be successively increased according to a first preset amplitude value; and simultaneously, the determined interval length attribute initial value is used as a starting point, and the interval length attribute value in the dotted line attribute value of the object is gradually reduced according to a second preset amplitude value, so that the difference value between the real line segment length attribute value and the interval length attribute value is gradually reduced.
Wherein, the reduction range can be set according to the animation effect. The first preset amplitude value may be the same or different in each adjustment, and the second preset amplitude value may be the same or different.
Assuming that the initial value of the dotted line attribute is set to [0,1000], in each adjustment, the real line segment length attribute value in the dotted line attribute value of the object is increased by a first preset amplitude value 1, and the interval length attribute value in the dotted line attribute value of the object is decreased by a second preset amplitude value 5, the dotted line attribute value after the first adjustment is [1, 995], and the object is drawn according to the adjusted dotted line attribute value, the dotted line attribute value after the second adjustment is [2, 990], and the object is drawn according to the adjusted dotted line attribute value, and so on, so that the animation effect for realizing the object can be obtained.
Therefore, in this embodiment, the difference between the real-line length attribute value and the interval length attribute value can be gradually reduced by gradually increasing the real-line length attribute value and decreasing the interval length attribute value, so as to gradually display the animation effect of the object.
It can be understood that the present application may also at least increase the real-line length attribute value in the dashed attribute values of the objects or decrease the interval length attribute value in the dashed attribute values of the objects in each adjustment, thereby achieving an animation effect of gradually displaying the objects.
In another alternative implementation, in a case where the animation effect of the object is an effect of fading away the object, an interval length attribute initial value of the broken line attribute initial values is smaller than a real line segment length attribute initial value.
The step of successively adjusting the dotted line attribute value of the object according to the determined dotted line attribute initial value and a preset adjustment strategy at least comprises one of the following steps:
successively reducing the real line segment length attribute value in the dotted line attribute value of the object according to a third preset amplitude value by taking the determined real line segment length attribute initial value as a starting point;
and gradually increasing the interval length attribute value in the dotted line attribute value of the object according to a fourth preset amplitude value by taking the determined interval length attribute initial value as a starting point.
In order to achieve the effect of fading out the object, of the broken-line attribute initial values, the interval-length attribute initial value may be set smaller than the real-line-segment-length attribute initial value.
In one example, after determining the initial value of the dashed-line attribute, the real-line-length attribute value in the dashed-line attribute values of the object may be successively decreased by a third preset amplitude value with the determined initial value of the real-line-length attribute as a starting point, so as to gradually increase the difference between the real-line-length attribute value and the interval-length attribute value.
Wherein the increase amplitude can be set according to animation effect. The third preset amplitude value reduced in each adjustment may be the same or different.
Therefore, in this embodiment, the difference between the real-line length attribute value and the interval length attribute value can be gradually increased by gradually decreasing the real-line length attribute value, so as to achieve an animation effect of gradually disappearing the object.
In one example, after determining the initial value of the interval length attribute, the interval length attribute value in the dashed line attribute values of the object may be successively increased by a fourth preset amplitude value with the determined initial value of the interval length attribute as a starting point, so as to gradually increase the difference between the real line segment length attribute value and the interval length attribute value.
Wherein the increase amplitude can be set according to animation effect. The fourth preset amplitude value increased in each adjustment may be the same or different.
Therefore, in this embodiment, the difference between the real-line segment length attribute value and the interval length attribute value can be gradually increased by gradually increasing the intermediate interval length attribute value, so as to achieve an animation effect of gradually disappearing the object.
In an example, after determining the initial value of the dashed-line attribute, the determined initial value of the real-line-segment length attribute may be used as a starting point, and the real-line-segment length attribute value in the dashed-line attribute values of the object may be successively reduced according to a third preset amplitude value; and simultaneously, the determined interval length attribute initial value is used as a starting point, and the interval length attribute value in the dotted line attribute value of the object is gradually increased according to a fourth preset amplitude value, so that the difference value between the real line segment length attribute value and the interval length attribute value is gradually increased.
Wherein the increase amplitude can be set according to animation effect. The third preset amplitude value may be the same or different in each adjustment, and the fourth preset amplitude value may be the same or different.
As can be seen, this embodiment may implement an animation effect of gradually disappearing the object by gradually decreasing the real-line-segment-length attribute value among the dotted-line attribute values of the object and gradually increasing the interval-length attribute value among the dotted-line attribute values of the object.
It can be understood that, the present application may further at least decrease the real-line length attribute value in the dashed attribute values of the object or increase the interval length attribute value in the dashed attribute values of the object in each adjustment, thereby achieving an animation effect of gradually disappearing the object.
In an alternative implementation, the gradual display and gradual fade-out animation effects may exist simultaneously in one animation.
In one example, in a preset adjustment strategy, whether to switch from the current animation effect to another animation effect may be determined according to an adjustment time of the animation effect. For example, the determined initial value of the real-line-segment length attribute is used as a starting point, and the real-line-segment length attribute value in the dotted-line attribute value of the object is gradually increased according to a first preset amplitude value; meanwhile, the determined interval length attribute initial value is used as a starting point, and the interval length attribute value in the dotted line attribute value of the object is gradually reduced according to a second preset amplitude value; and when the adjusting time reaches the first set time, taking the adjusted dotted line attribute value as a starting point, successively reducing the real line segment length attribute value in the dotted line attribute value of the object according to a third preset amplitude value, simultaneously successively increasing the interval length attribute value in the dotted line attribute value of the object according to a fourth preset amplitude value, and when the adjusting time reaches the second set time, ending the adjusting operation of the dotted line attribute value and the drawing operation of the object.
Therefore, whether the adjustment method is switched or not is determined by adjusting the time, so that different animation effects can be realized.
In one example, in a preset adjustment strategy, whether to switch from the current animation effect to another animation effect may be determined according to a dotted attribute value of the object. In the adjusting process, when the adjusted dotted line attribute value reaches the set dotted line attribute value, the current animation effect can be switched to other animation effects. For example, the determined initial value of the real-line-segment length attribute is used as a starting point, and the real-line-segment length attribute value in the dotted-line attribute value of the object is gradually increased according to a first preset amplitude value; and when the real-line-segment-length attribute value reaches the first set real-line-segment-length attribute value, successively reducing the real-line-segment-length attribute value in the dotted-line attribute value of the object by taking the adjusted dotted-line attribute value as a starting point according to a third preset amplitude value, and when the real-line-segment-length attribute value reaches the second set real-line-segment-length attribute value, ending the adjustment operation of the dotted-line attribute value and the drawing operation of the object.
Therefore, whether the adjustment method is switched or not is determined by the dotted line attribute value of the object, so that different animation effects can be realized.
In the preset adjustment strategy, an adjustment ending strategy is not required to be set, so that the object is always in the adjustment process.
In an optional implementation manner, in order to avoid resource waste caused by constant adjustment, an adjustment ending policy may be set in the preset adjustment policy.
In one example, when the adjusted dotted-line attribute value reaches a preset dotted-line attribute end value, the adjustment operation of the dotted-line attribute value and the drawing operation of the object are ended.
For example, when the difference between the real-line-segment-length attribute value and the interval-length attribute value is gradually reduced by gradually increasing the real-line-segment-length attribute value, if the initial value of the dotted-line attribute is set to [0,1000], the end value of the dotted-line attribute may be [1000,1000], and when the real-line-segment-length attribute value is increased to 1000, no adjustment is performed, that is, the adjustment operation of the dotted-line attribute value and the drawing operation of the object are ended, thereby avoiding resource waste caused by continuous operation.
Therefore, by setting the end value of the dotted line attribute, when the adjusted dotted line attribute value reaches the preset end value of the dotted line attribute, the adjustment operation of the dotted line attribute value and the drawing operation of the object are ended, thereby avoiding resource waste caused by continuous operation.
In another example, when the time to adjust the dotted-line attribute value of the object reaches the set end time, the adjustment operation of the dotted-line attribute value and the drawing operation of the object are ended.
Therefore, by setting the end time, when the time of the dotted line attribute value of the adjustment object reaches the set end time, the adjustment operation of the dotted line attribute value and the drawing operation of the object are ended, thereby avoiding resource waste caused by continuous operation.
The application lists an application scenario for explanation.
As shown in fig. 1C, fig. 1C is a schematic diagram of an application example of the animation processing method shown in the present application. In this example, a trajectory line supported by Canvas may be drawn, the dashed attribute of the trajectory line is set to [0,1000], a completely empty trajectory line may be obtained, and then the real line length attribute value (i.e., the first parameter) of the trajectory line is adjusted up frame by frame, so that the animation effect as shown in the figure may be obtained. It can be understood that, for convenience of illustration, the drawing is not redrawn at the original position, but the drawn graphics are sequentially displayed on the same page, and in the actual operation process, the drawing application can be repeatedly drawn at the same position, so that the animation effect can be seen.
