具体实施方式
为使本公开实施例的目的、技术方案和优点更加清楚，下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
如图1所示，在实际应用中，当用户需要对当前视频添加文本时，需要预先确定当前帧视频中需要添加文本的文本添加位置(视频内容中的虚框)，进而再在键盘提供的输入框中输入待输入文本。当待输入文本输入完成后，在文本添加位置显示该待输入文本的渲染结果。例如：如图2所示，以待输入文本为“#打卡”为例，当“#打卡”在键盘提供的 输入框中输入完成，则在文本添加位置上显示“#打卡”对应的渲染结果。
由于待输入文本的输入位置和渲染结果的显示位置是不同的控件提供的，且显示位置也存在较大差异，因此，采用该种方式进行文本编辑，不利于用户快速确定当前的渲染结果是否满足用户的文本编辑意图。
基于此，本公开实施例提供了一种文本显示方法，能够用户在输入目标文本的指定位置编辑上，直接查看到目标文本渲染后的结果，以便用户快速确定当前在指定编辑位置上显示的对齐后渲染结果是否满足自身需求，从而有助于增强视频编辑软件执行文本编辑的交互能力，使显示目标文本渲染后的结果的方式更直观且友好。
根据本公开实施例，提供了一种文本显示方法实施例，需要说明的是，在附图的流程图示出的步骤可以在诸如一组计算机可执行指令的计算机系统中执行，并且，虽然在流程图中示出了逻辑顺序，但是在某些情况下，可以以不同于此处的顺序执行所示出或描述的步骤。
在本实施例中提供了一种文本显示方法，可用于上述的电子设备，例如，电脑，移动终端等等，图3是根据本公开实施例的文本显示方法的流程图，如图3所示，该流程包括如下步骤：
步骤S301，获取多帧视频图像。
多帧视频图像中包括待进行文本编辑的目标帧视频图像。多帧视频图像可以是组成视频的全部帧视频图像，也可以是根据用户需求截取的部分帧视频图像。
多帧视频图像对应的视频来自使用摄像设备(例如：摄像机、智能手机、监控摄像头等)实时录制的场景。该视频可以是从本地数据库中获取得到的，也可以是从云端数据库中下载得到的。在此对待识别视频的获取方式并不做任何限定，具体根据实际需求进行设置即可。
步骤S302，从目标帧视频图像的指定编辑位置上获取目标文本，并将目标文本显示在指定编辑位置上。
指定编辑位置可以理解为是被允许可以进行文本编辑的位置，该指定编辑位置可以是用户指定位置，也可以是预设的默认位置。目标文本可以理解为是用户需要添加在目标帧视频图像上的文本。
当在目标帧视频图像上的指定编辑位置上获取到目标文本，则表征用户在指定编辑位置上输入了目标文本，因此，为便于用户明确当前在指定编辑位置上输入的内容，则将目标文本显示在指定编辑位置上，以便用户能够直观地查看当前输入的目标文本，以当目标文本输入错误时，可以及时调整，得到正确的目标文本。
步骤S303，渲染目标文本，得到渲染结果。
为使目标文本的显示更美观，则对当前获取的目标文本进行渲染，进而得到渲染结果。其中，对目标文本进行渲染的内容包括但不限于：字体、字号、颜色、对齐方式、阴影和 描边等效果。其中，渲染后渲染结果可以为静态的图片或动态的动画效果，具体取决于用户的选择，在此不进行限定。
步骤S304，将渲染结果与目标文本对齐，并将对齐后的渲染结果显示在指定编辑位置上。
由于渲染后的渲染结果可能与目标文本之间的差异较大，因此，为便于用户能够更直观的查看目标文本渲染后的显示结果，则建立渲染结果与目标文本之间的对应关系，以将渲染结果能够与目标文本对齐，进而保障对齐后的渲染结果可以直接在指定编辑位置上进行显示，便于用户可以更直观的确认当前渲染效果是否满足自身的需求，使显示目标文本渲染后的结果的方式更友好，从而有助于用户快速完成文本编辑。
本实施例提供的文本显示方法，在从多帧视频图像中确定待进行文本编辑的目标帧视频图像后，在目标帧视频图像中需要进行文本编辑的指定编辑位置上，获取并显示目标文本，进而对该目标文本进行渲染，得到渲染结果。为便于用户能够直观的从指定位置编辑上查看到目标文本渲染后的结果，则将渲染结果与目标文本对齐，进而将对齐后的渲染结果显示在指定编辑位置上，以便用户快速确定当前在指定编辑位置上显示的对齐后渲染结果是否满足自身需求，从而有助于增强视频编辑软件执行文本编辑的交互能力，使显示目标文本渲染后的结果的方式更友好，有利于提升用户的使用体验。
在一些可选的实施场景中，通过上述文本显示方法显示目标文本的渲染显示结果的过程可以如图4至图6所示。其中，如图4所示，目标帧视频图像中的虚框即为指定编辑位置。如图5所示，在用户选中指定编辑位置后，可以在待输入文本上面输入目标文本(“#打卡”)，进而在“#打卡”输入完成后，显示在该指定编辑位置上。以渲染效果是将“#打卡”加粗显示为例，则将对齐后的渲染结果显示指定编辑位置上的示意图即可如图6所示。其中，与“#打卡”叠加显示的加粗的“#打卡”是经过对齐后的渲染结果，可以将其作为目标文本的渲染显示结果。
在本实施例中提供了一种文本显示方法，可用于上述的电子设备，例如，电脑，移动终端等等，图7是根据本公开实施例的文本显示方法的流程图，如图7所示，该流程包括如下步骤：
步骤S701，获取多帧视频图像。
步骤S702，从目标帧视频图像的指定编辑位置上获取目标文本，并将目标文本显示在指定编辑位置上。
步骤S703，渲染目标文本，得到渲染结果。
步骤S704，将渲染结果与目标文本对齐，并将对齐后的渲染结果显示在指定编辑位置上。
具体地，上述步骤S704包括：
步骤S7041，根据目标文本的当前字号，确定第一显示窗口显示当前字号与第二显示 窗口之间显示当前字号的显示比值。
第一显示窗口为显示多帧视频图像的窗口，第二显示窗口为显示渲染结果的窗口。由于渲染结果和目标文本分别采用不同的窗口进行显示，且不同窗口在显示文本时可能存在差异，因此，为便于将渲染结果与目标文本进行针对性对齐，则在确定目标文本当前字号的情况下，确定第一显示窗口显示当前字号与第二显示窗口之间显示当前字号的显示比值，以便通过该显示比值可以确保在第二显示窗口显示的对齐后的渲染结果的字号与该当前字号一致。
在一可选地实施场景中，在当前字号确定的情况下，显示比值可以采用下述方式计算：
目标文本用于在第一显示窗口显示的当前字号(fontSize)的单位为磅(pt)，将其转换像素的表达式如下：systemSize*ScreenScale，其中，systemSize是以磅为单位的字号大小，ScreenDPI是第一显示窗口每英寸的像素密度。
第二显示窗口对应的像素转换表达式如下：fontSize*300/72.0，其中，300表示第二显示窗口每英寸的像素密度，72.0是1英寸中的磅数。
为将渲染结果与目标文本对齐，则建立如下关系式：
fontSize*300/72.0＝systemSize*ScreenScale；
fontSize＝systemSize*ScreenScale*72.0/300；
fontSize＝systemSize*(Player2Width/(Player1Width*ScreenScale))*ScreenScale*72.0/300；
最终得到的显示比值rate＝Player2Width/player1Width)*(72.0/300.0)。
其中，Player2Width为第二显示窗口的显示宽度。Player1Width为第一显示窗口的显示宽度。在一示例中，Player2Width可以为预设的固定值，例如：720.0。
步骤S7042，基于显示比值，调节渲染结果，得到对齐后的渲染结果。
基于显示比值，可以明确渲染结果的调节方向，进而可以针对性对齐，得到对齐后的渲染结果，从而后续进行显示时，可以保障对齐后的渲染结果的可读性不会受到影响，有利于增强目标文本的渲染显示结果的可视化效果，便于提升用户的使用体验。
在一可选的实施方式中，上述步骤S7042包括：
步骤a1，根据第一显示窗口按照当前字号显示的目标文本，确定文本配置参数对应的第一数值。
文本配置参数可以理解为是在当前字号下，通过第一显示窗口下显示目标文本的配置参数。文本配置参数包括但不限于以下参数：字体大小、文本宽度、背景圆角、字间距、行间距、阴影宽度等。为便于明确调节方向，则先确定在第一显示窗口显示目标文本时，该文本配置参数对应的第一数值。
步骤a2，基于显示比值以及第一数值，确定文本配置参数在第二显示窗口下的第二数值。
基于显示比值以及第一数值，可以得到适用于第二显示窗口的调整后的数值，进而可 以确保文本在不同的显示窗口上保持一致的配置效果，从而可以提供统一和可读性良好的用户体验。
在一可选地实施场景中，通过第一数值确定第二数值的计算过程可以如下表1所示：
表1
其中，文本编辑组件为支持用户在第一显示窗口内输入目标文本的组件。
步骤a3，将渲染结果的文本配置参数按照第二数值进行调节，得到对齐后的渲染结果。
为使渲染结果的显示字号与当前字号相同，则将渲染结果的文本配置参数按照第二数值进行针对性调节，进而得到能够与目标文本保持一致的对齐后的渲染结果。
在一些可选地实施方式中，若文本配置参数为最大显示宽度，则上述步骤a3包括：
步骤a31，确定目标文本在第一显示窗口下的第一显示行数；
步骤a32，确定渲染结果在第二显示结果下的第二显示行数；
步骤a33，若第二显示行数大于第一显示行数，则在目标文本中添加换行符，以将第一显示行数变为第二显示行数。
具体的，根据第一显示窗口的最大显示宽度，确定当前采用第一显示窗口显示目标文本时的第一显示行数。根据第二显示窗口的最大显示宽度，确定对齐后的渲染结果在第二显示结果下的第二显示行数。为避免出现渲染后的第二显示行数与第一显示行数不一致而影响用户视觉体验的情况发生，则将第二显示行数与第一显示行数进行对比。若第二显示行数大于第一显示行数，则在目标文本中添加换行符，以将第一显示行数变为第二显示行数，进而保障对齐后的渲染结果与目标文本显示的行数相同。
步骤S7043，将对齐后的渲染结果显示在指定编辑位置上。
本实施例提供的文本显示方法，将渲染结果与目标文本进行对齐，进而在指定编辑位 置上显示对齐后的渲染结果，可以保障对齐后的渲染结果的可读性不会受到影响，进而有利于增强目标文本的渲染显示结果的可视化效果，便于提升用户的使用体验。
在本实施例中提供了一种文本显示方法，可用于上述的电子设备，例如，电脑，移动终端等等，图8是根据本公开实施例的文本显示方法的流程图，如图8所示，该流程包括如下步骤：
步骤S801，获取多帧视频图像。
步骤S802，从目标帧视频图像的指定编辑位置上获取目标文本，并将目标文本显示在指定编辑位置上。
步骤S803，渲染目标文本，得到渲染结果。
步骤S804，将渲染结果与目标文本对齐，并将对齐后的渲染结果显示在指定编辑位置上。
步骤S805，若目标帧视频图像为连续的多帧图像，则在多帧图像播放的过程中，响应对对齐后的渲染结果执行的位置移动指令，追踪对齐后的渲染结果的移动轨迹，并基于多帧图像的当前播放帧率，确定对齐后的渲染结果的位置刷新速率。
在预览对齐后的渲染结果在目标帧视频图像中的显示情况，则播放多帧图像。但在播放多帧图像的过程中，若接收到用户对对齐后的渲染结果触发的位置移动指令，则追踪对齐后的渲染结果的移动轨迹，以确定对齐后的渲染结果在每一帧图像上对应显示的目标编辑位置。
为便于对齐后的渲染结果显示效果更友好，则基于多帧图像的当前播放帧率，确定对齐后的渲染结果的位置刷新速率，以便在移动对齐后的渲染结果的过程中，对齐后的渲染结果能够跟随位置的移动而进行相应显示，进而有助于增强用户的使用体验。
具体的，上述步骤S805包括：
步骤b1，将当前播放帧率切换成目标播放帧率，并基于目标播放帧率确定对齐后的渲染结果的第二位置刷新速率。
目标播放帧率高于当前播放帧率。为提高的对齐后的渲染结果的拖动流畅度，则将当前播放帧率切换成目标播放帧率，进而基于目标播放帧率确定对齐后的渲染结果的第二位置刷新速率，能够保障对齐效果更佳。例如：若当前播放帧率为30帧/秒，则可以将目标播放帧率调节为60帧/秒。
在一些可选的实施方式中，上述步骤S805还包括：
步骤b2，响应对齐后的渲染结果停止移动，将目标播放帧率恢复成当前播放帧率。
由于调节目标播放帧率的目的是保障对齐后的渲染结果能够跟随用户手势的移动而对齐显示，便于提升用户的预览体验，而并非是针对多帧图像的播放速度进行调节，因此，在用户停止对对齐后的渲染结果的移动之后，将目标播放帧率恢复成当前播放帧率。
步骤S806，按照位置刷新速率，将对齐后的渲染结果显示在多帧图像中每一帧图像的 目标编辑位置上。
按照位置刷新速率，在每一帧图像的目标编辑位置上显示对应的对齐后的渲染结果，能够保障对齐后的渲染结果在多帧图像之间可以保持一致，进而实现视觉上的连贯性，从而可以提高视觉效果、增强用户体验。
本实施例提供的文本显示方法，能够丰富对视频进行文本编辑的功能多样性，进而不仅可以提高视觉效果，还可以增强用户体验。
在一可选的实施方式中，为便于用户能够清晰的查看对齐后的渲染效果，则将指定编辑位置上显示的目标文本隐藏。例如：结合图5所示的目标文本，则显示的时候如图9所示。
在一可选的实施场景中，第一显示窗口可以是由电子设备当前操作系统的第一引擎提供的，第二显示窗口是由第二引擎提供的。其中，第一引擎可以理解为是嵌入在当前操作系统中，用于执行文本编辑任务的引擎。即，当用户需要输入目标文本时，调用第一引擎，以使用户可以通过第一引擎提供的文本编辑组件输入目标文本。第二引擎可以理解为是用于执行文本渲染任务的引擎。当需要渲染目标文本时，第二引擎从第一引擎中获取待进行文本渲染的目标文本，并通过第二引擎提供的文本渲染组件对目标文本进行渲染，得到渲染结果。在一示例中，如图10所示，在对目标帧视频图像执行文本编辑的过程中，第二引擎位于第一引擎下方，进而便于将渲染结果能够更好的与用户输入的目标文本对齐。
基于相同构思，本公开还提供一种视频编辑软件的组件框架，如图11所示，当用户在目标帧视频图像的指定编辑位置上输入目标文本时，禁用第二引擎提供的文本渲染组件，显示第一引擎提供的文本编辑组件，以便用户在该文本编辑组件上进行输入和显示目标文本。当目标文本输入完成后，自动隐藏该文本编辑组件，启动第二引擎对目标文本进行渲染，进而通过文本对齐的方式，将对齐后的渲染结果显示在输入目标文本的位置(指定编辑位置)上，从而利用视觉差达到让视频编辑软件可以对文本编辑和高级显示效果同时支持的目的。
在本实施例中还提供了一种文本显示装置，该装置用于实现上述实施例及优选实施方式，已经进行过说明的不再赘述。如以下所使用的，术语“模块”可以实现预定功能的软件和/或硬件的组合。尽管以下实施例所描述的装置较佳地以软件来实现，但是硬件，或者软件和硬件的组合的实现也是可能并被构想的。
