实施例二 Embodiment 2
参见图2，本实施例提供一种基于手绘视频的GIF文件生成装置，包括：Referring to FIG. 2, the present embodiment provides a device for generating a GIF file based on a hand-drawn video, including:
读取模块1，用于读取手绘视频项目中的场景动画；The reading module 1 is used to read the scene animation in the hand-painted video project;
计算模块2，用于计算所述场景动画的动画时长和所述场景动画之间的间隔； Calculation module 2, for calculating the animation duration of the scene animation and the interval between the scene animation;
填充模块3，用于根据所述动画时长向所述场景动画填充动画帧，根据所述间隔的数量填充间隔帧。Filling module 3, configured to fill animation frames to the scene animation according to the animation duration, and fill interval frames according to the number of intervals.
需要说明的是，参见图3，手绘视频项目是指为了生成手绘视频文件(例如，MP4格式文件)而创建的项目，项目组成形式为项目配置文件和对应的资源文件。其中，配置文件中包含了多个场景，每个场景下包括多个动画。具体的，可以用场景页的形式进行说明，每个场景页中包含动画元素的动画信息，资源文件以场景页为单位保存了对应的资源文件。It should be noted that, referring to FIG. 3 , a hand-drawn video project refers to a project created to generate a hand-drawn video file (eg, MP4 format file), and the project consists of a project configuration file and a corresponding resource file. Among them, the configuration file contains multiple scenes, and each scene includes multiple animations. Specifically, the description can be made in the form of scene pages, each scene page contains animation information of animation elements, and the resource file saves the corresponding resource file in units of scene pages.
还需要说明的是，每个场景动画具有时长，每个场景动画之间也具有时长，场景动画的时长以及场景动画之间的时长可以为默认值，也可以为用户指定值。因为GIF导出时需要对应的画面区域和时长，如果用户做了对应的指定，可以依据用户的指定，若用户未指定，则使用当前手绘视频项目的默认数据。It should also be noted that each scene animation has a duration, and each scene animation also has a duration. The duration of the scene animation and the duration between the scene animations may be default values or values specified by the user. Because the corresponding screen area and duration are required when GIF is exported, if the user makes the corresponding designation, it can be based on the user's designation. If the user does not designate it, the default data of the current hand-drawn video project is used.
还需要说明的是，动画帧和间隔帧都是一种图像帧。图像帧是指GIF文件的组成部分，除文件头外，还包括图像数据和控制数据。It should also be noted that both the animation frame and the interval frame are a kind of image frame. Image frame refers to the component of GIF file, which includes image data and control data in addition to the file header.
图像数据指的是像素组成，也即当前帧的图像。Image data refers to the pixel composition, that is, the image of the current frame.
控制数据指的是当前帧相对于上一帧的延迟时长。Control data refers to the delay time of the current frame relative to the previous frame.
如果每一帧的延迟时长都是相等的，可以简单理解为有固定等长的帧率；如果每帧的延迟不等，则理解为非等长帧率，这样的好处，是在某些画面保持一段时间无变化的情况下，可以节约帧数，减少文件体积和绘制性能消耗。If the delay time of each frame is equal, it can be simply understood as having a fixed frame rate of equal length; if the delay of each frame is unequal, it is understood as an unequal frame rate. The advantage of this is that in some pictures If there is no change for a period of time, the number of frames can be saved, file size and drawing performance consumption can be reduced.
还需要说明的是，还可以计算场景动画的分辨率，该分辨率是指动画场景的尺寸。分辨率可以默认是场景动画的完整尺寸，也可以是用户指定的场景动画的局部尺寸。在基于用户指定分辨率时，可以不但满足用户对场景动画的制作需求，而且可以减小帧数和动画体积。It should also be noted that the resolution of the scene animation can also be calculated, and the resolution refers to the size of the animation scene. The resolution can default to the full size of the scene animation, or it can be a user-specified partial size of the scene animation. When the resolution is specified by the user, it can not only meet the user's production requirements for scene animation, but also reduce the number of frames and animation volume.
还需要说明的是，还可以读取用户指定的透明度要求，若指定保留透明度，在处理后续数据时会把动画背景做透明通道处理，以减小帧数和动画体积。It should also be noted that the transparency requirements specified by the user can also be read. If the transparency is specified to be retained, the animation background will be processed as a transparent channel when processing subsequent data to reduce the number of frames and animation volume.
还需要说明的是，对动画部分***动画帧形成动画，对间隔部分***间隔帧连续动画。间隔帧作用在于间隔相邻动画，能够有效减小帧数和动画体积，降低绘制性能消耗，有利于视频文件的使用和传播。It should also be noted that the animation frame is inserted into the animation part to form an animation, and the interval frame is inserted into the interval part to form a continuous animation. The function of interval frames is to separate adjacent animations, which can effectively reduce the number of frames and animation volume, reduce the consumption of drawing performance, and is conducive to the use and dissemination of video files.
还需要说明的是，根据间隔的数量填充间隔帧的步骤包括：根据每个间隔的起点和终点，计算所述间隔的数量，填充所述间隔帧。其中，通过间隔起点和终点的统计，可以精确计算得到间隔数量，从而确保间隔内都能填充间隔帧，能够从整体上有效减小帧数和动画体积，降低绘制性能消耗，有利于视频文件的使用和传播。It should also be noted that the step of filling the interval frames according to the number of intervals includes: calculating the number of the intervals according to the start point and the end point of each interval, and filling the interval frames. Among them, through the statistics of the start and end points of the interval, the number of intervals can be accurately calculated, so as to ensure that the interval frames can be filled in the interval, which can effectively reduce the number of frames and animation volume as a whole, reduce the consumption of drawing performance, and is conducive to the improvement of video files. use and dissemination.
还需要说明的是，动画时长为默认时长或用户指定时长。其中，动画时长提供默认时长或用户指定时长的选项，可以在默认时长情况下预设适当的动画体积，也可以在用户指定时长情况下满足用户对动画体积的个性化需求。It should also be noted that the animation duration is a default duration or a user-specified duration. Among them, the animation duration provides the option of a default duration or a user-specified duration. An appropriate animation volume can be preset under the default duration, or the user's personalized needs for the animation volume can be met under the user-specified duration.

S32、判断所述场景动画是否为动态动画；S32, determine whether the scene animation is a dynamic animation;
S33、如果所述场景动画为动态动画，则以所述动态动画开始前的最后一帧图像作为填充背景，在所述动态动画每一帧中计算动画区域，以填充所述动画帧到计算得到的动画区域。S33, if the scene animation is a dynamic animation, use the last frame of the image before the dynamic animation starts as the filling background, and calculate the animation area in each frame of the dynamic animation to fill the animation frame until the calculation is obtained. animation area.

31、第一填充单元，用于如果场景动画为手绘动画，则以手绘动画开始前的最后一帧图像作为填充背景，以填充动画帧到图像指定区域。31. The first filling unit is used for filling the animation frame to the designated area of the image by using the last frame of image before the start of the hand-drawn animation as the filling background if the scene animation is a hand-drawn animation.
32、动态动画判断单元，用于判断场景动画是否为动态动画；32. A dynamic animation judgment unit, used for judging whether the scene animation is a dynamic animation;
33、第二填充单元，用于如果场景动画为动态动画，则以动态动画开始前的最后一帧图像作为填充背景，在动态动画每一帧中计算动画区域，以填充动画帧到图像指定区域。33. The second filling unit is used for if the scene animation is a dynamic animation, the last frame of the image before the start of the dynamic animation is used as the filling background, and the animation area is calculated in each frame of the dynamic animation to fill the animation frame to the designated area of the image .
需要说明的是，手绘动画是一种位置不变，而动画以手绘形式逐渐出现的动画。动态动画是一种位置变化的动画，如移动、旋转、缩放等。It should be noted that the hand-drawn animation is an animation in which the position does not change, and the animation gradually appears in the form of hand-drawn. Dynamic animation is an animation of position changes, such as moving, rotating, scaling, etc.
还需要说明的是：对场景动画进行类型区分，在场景动画为手绘动画的情况下，以手绘动画开始前的最后一帧图像作为填充背景，以填充动画帧到图像指定区域，可以将动画帧填充到填充背景的固定区域，形成对填充背景固定区域的充分调取使用，避免大量填充前的区域计算，节约计算资源。It should also be noted that: to distinguish the type of scene animation, if the scene animation is a hand-drawn animation, the last frame of the image before the start of the hand-drawn animation is used as the filling background to fill the animation frame to the designated area of the image, and the animation frame can be Fill to the fixed area of the filled background to form a full call and use of the fixed area of the filled background, avoid a large number of area calculations before filling, and save computing resources.
另外，对填充背景固定区域的使用也减小了动画体积，降低绘制性能消耗。In addition, the use of filling the fixed area of the background also reduces the animation volume and reduces the drawing performance consumption.
还需要说明的是，对场景动画进行类型区分，在场景动画为手绘动画时进行固定区域填充，在场景动画为动态动画时进行动态区域填充，形成对填充背景固定区域的充分调取使用，避免大量填充前的区域计算，节约计算资源。It should also be noted that the type of scene animation is distinguished. When the scene animation is a hand-drawn animation, the fixed area is filled, and when the scene animation is a dynamic animation, the dynamic area is filled, so as to fully call and use the fixed area of the filled background to avoid The area calculation before a large number of filling saves computing resources.
另外，对填充背景固定区域的使用也减小了动画体积，降低绘制 性能消耗，对填充背景动态区域的使用，使得动画开始时的完整动画得以保留，每一帧动画的动画区域得以动态更新。In addition, the use of the fixed area of the filled background also reduces the animation volume and the consumption of drawing performance. The use of the dynamic area of the filled background allows the complete animation at the beginning of the animation to be preserved, and the animation area of each frame of animation can be dynamically updated.
