技术领域
本申请涉及计算机技术领域，尤其涉及一种显示窗口的创建方法、装置及电子设备。
背景技术
电视墙是指由至少一块显示器组成的一整面显示墙。通常电视墙上可创建至少一个显示窗口，由每个显示窗口显示各自的视频。

其中，电视墙上包括多个接口，每个接口与解码设备的解码输出口相连，用于接收解码设备发送的解码后的视频流。电视墙按照电视墙上的接口将电视墙预先划分为至少一个物理输出区域，不同物理输出区域对应不同的接口。现有的方式在部署完显示窗口后，控制电视墙显示时，显示窗口会出现窗口黑边。
发明内容

参见图1，图1是本申请一示例性实施例示出的一种电视墙控制组网图，该组网至少包括：管理平台、解码设备和电视墙。
上述管理平台，用于管理电视墙，比如在电视墙预部署显示窗口。用户可以通过管理平台实现对电视墙的控制。
解码设备，解码设备与电视墙相连，用于将待传输给电视墙的视频数据进行解码，并将解码后的视频数据发送给电视墙，在电视墙的窗口中进行显示。
电视墙，是由至少一块显示器组成的一整面显示墙。电视墙上包括多个接口，电视墙上的接口与解码设备的解码输出口相连，用于接收解码设备发送的解码后的视频流。按照电视墙上的接口，电视墙被预先划分为至少一个物理输出区域，不同物理输出区域对应不同的接口。此外，电视墙还预先部署了至少一个用于播放视频的显示窗口。显示窗口要依据物理输出区域进行创建，以使得解码输出口输出的解码后的数据会在该物理输出区域中部署的显示窗口中显示，并且创建的显示窗口不会产生窗口黑边。
在介绍本申请提供的方法之前，先对本申请涉及的几个概念进行介绍。
1)物理输出区域
按照电视墙上的接口，电视墙被预先划分为至少一个物理输出区域，每个物理输出区域对应的接口与解码设备的一个解码输出口相连。
如图2所示，假设电视墙包括4个接口，这4个接口分别连接了解码设备上的解码输出口A、解码输出口B、解码输出口C和解码输出口D。电视墙被预先划分出口了4个物理输出区域，分别是与解码输出口A对应的物理输出区域A、与解码输出口B对应的物理输出区域B、与解码输出口C对应的物理输出区域C、与解码输出口D对应的物理输出区域D。
2)虚拟输出区域
虚拟输出区域与物理输出区域一一对应，物理输出区域是指电视墙上真实的被划分出的输出区域。多个虚拟输出区域可以组成虚拟输出区域阵列。而虚拟输出区域是管理平台上用于描述物理输出区域的信息。比如，电视墙上划分出的物理输出区域有16个，排布方式为4*4，则管理平台上维护了与各物理输出区域对应的虚拟输出区域，虚拟输出区域也有16个，排布方式也为4*4，且这16个虚拟输出区域组成一个虚拟输出区域阵列。
例如，虚拟输出区域的区域坐标可以是物理输出区域在电视墙坐标系中真实的区域坐标，也可以是物理输出区域在电视墙坐标系中真实的区域坐标映射到管理平台坐标系下所产生的坐标。这里只是对虚拟输出区域进行示例性地说明，不对其进行具体地限定。
3)显示窗口
显示窗口用于播放视频数据。显示窗口的创建数量由用户进行设定，本申请所要实现的目的就是在物理输出区域上自动创建显示窗口阵列，以使得创建出的每个显示窗口不产生窗口黑边。
例如，如图3所示，假设物理输出区域为2*2，显示窗口阵列为5*5，则在物理输出区域上创建出的显示窗口阵列如图3所示。其中，虚线框表示物理输出区域，实线框表示显示窗口。
4)显示窗口的窗口黑边产生原因
当显示窗口的第一边界、与该第一边界所在的物理输出区域或虚拟输出区域中对应该第一边界的第二边界之间的边界距离在该第一边界对应的预设范围内，则显示窗口会出现黑边。
如图4所示，比如显示窗口的右边界与物理输出区域的右边界的距离在显示窗口的右边界对应的(0，L1)的范围内，则显示窗口出现黑边。
再比如，显示窗口的下边界与物理输出区域的下边界的距离在显示窗口的下边界对应的(0，L2)的范围内，则显示窗口出现黑边。再比如，以LED显示墙为例，可以将L1*L2理解为最小显示像素，当显示窗口垂直于L1的边缘与物理输出区域垂直于L1的边缘之间的距离小于L1，和/或显示窗口垂直于L2的边缘与物理输出区域垂直于L2的边缘之间的距离小于L2时，解码设备无法有效驱动 以在最小显示像素内进行显示，从而导致显示窗口出现黑边。
当显示窗口的右边界与物理输出区域的右边界(和/或左边界)的距离不在显示窗口的右边界对应的预设范围内、显示窗口的左边界与物理输出区域的左边界(和/或右边界)的距离不在显示窗口的左边界对应的预设范围内、显示窗口的上边界与物理输出区域的上边界(和/或下边界)的距离不在显示窗口的上边界对应的预设范围内、显示窗口的下边界与物理输出区域的下边界(和/或上边界)的距离不在显示窗口的下边界对应的预设范围内时，显示窗口不会出现窗口黑边。
其中，需要说明的是，显示窗口上、下边界对应的预设范围可以是相同的范围，也可以是不同的范围。显示窗口左、右边界对应的预设范围可以相同的范围、也可以是不同的范围。这里只是示例性地说明，不对其进行具体地限定。
需要说明的是，若显示窗口的窗口区域与目标虚拟输出区域的坐标信息是电视墙坐标系下的坐标信息，则上述第一边界和第二边界之间的边界距离，预设范围均是电视墙坐标系下的信息。
若窗口区域与目标虚拟输出区域的坐标信息是管理平台坐标系下的坐标信息，则上述第一边界和第二边界之间的边界距离，预设范围均是管理平台坐标系下的信息。下文不再赘述。
本申请旨在提出一种显示窗口创建方法，管理平台确定初始窗口区域。然后管理平台从所述电视墙已被划分的多个虚拟输出区域中确定与所述初始窗口区域具有交集的至少一个目标虚拟输出区域。管理平台依据所述初始窗口区域和所述目标虚拟输出区域上相对应的边界之间的距离调整所述初始窗口区域，以控制所述电视墙依据调整后的初始窗口区域创建的目标显示窗口在显示视频时不产生窗口黑边。
管理平台在创建显示窗口时，会确定出初始窗口区域，并依据初始窗口区域和与该初始窗口区域具有交集的目标虚拟输出区域上相对应的边界之间的距离调整所述初始窗口区域，以使得基于调整后的初始窗口区域创建出的显示窗口不会产生窗口黑边。
参见图5，图5是本申请一示例性实施例示出的一种显示窗口创建方法的流程图，该方法可应用在图1所示的管理平台上，可包括如下所示步骤。
步骤501：管理平台确定待创建的目标显示窗口的初始窗口区域。
在本申请中，由于管理平台用于管理电视墙，所以管理平台上维护有电视墙的尺寸信息，以及电视墙上被划分出的各物理输出区域的相关信息。其中，物理输出区域的相关信息包括：物理输出区域尺寸、物理输出区域标识、以及物理输出区域位置信息等，这里只是对物理输出区域的相关信息进行示例性地说明，不对其进行具体地限定。
由于管理平台上维护了物理输出区域的相关信息，所以管理平台可以得到与各物理输出区域对应的虚拟输出区域。
需要说明的是，管理平台上维护的电视墙的尺寸信息，以及各虚拟输出区域的尺寸信息可以是电视墙以及物理输出区域在电视墙坐标系下的真实尺寸信息，也可以是电视墙以及物理输出区域在电视墙坐标系下的真实尺寸信息在管理平台坐标系下映射出的尺寸信息，这里只是示例性地说明，不对其进行具体地限定。
在本申请中，管理平台被预先配置了需要创建的指定显示窗口阵列的相关信息。比如，该相关信息包括：指定显示窗口阵列中的显示窗口数量以及排布方式(比如管理平台预先被配置了要创建M*N的显示窗口阵列)，以及各显示窗口的标识信息(比如管理平台还维护了这M*N个待创建的显示窗口的编号等信息)。这里只是示例性地说明，不对其进行具体地限定。
其中，上述指定显示窗口阵列是由至少一个显示窗口构成的。比如，当显示窗口为1个时，指定显示窗口阵列包括一个显示窗口；当显示窗口为多个(比如显示窗口数量为M*N)时，指定显示窗口阵列由多个显示窗口按照M行N列的次序排列形成。
管理平台可控制电视墙在物理输出区域上创建出指定显示窗口阵列，使得指定显示窗口阵列中的每个显示窗口不产生窗口黑边。
下面从步骤501的触发条件和步骤501的实现方法来对步骤501进行详细地说明。
1)步骤501的触发条件
在本申请中，一般情况下，除指定显示窗口阵列中的最后一个显示窗口、和/或指定显示窗口阵 列中的一行中的最后一个显示窗口、和/或指定显示窗口阵列中的一列中的最后一个显示窗口以外的其他显示窗口，均可按照步骤501至步骤503进行创建。由于在显示窗口的创建过程中，管理平台会对显示窗口的初始窗口区域的边界进行调整，并且后一个显示窗口的窗口区域是基于已确定的显示窗口区域确定的，这就会使得在确定指定显示窗口阵列中的最后一个显示窗口区域，和/或在确定指定显示窗口阵列中的一行中的最后一个显示窗口区域，和/或在确定指定显示窗口阵列中的一列中的一列最后一个显示窗口区域时，由于电视墙的剩余窗口创建区域不满足预设的窗口创建条件，致使指定显示窗口阵列中的、和/或指定显示窗口阵列中一行中的、和/或指定显示窗口阵列中的一列中的最后一个显示窗口无法创建。
因此，在一种可选的实现方式中，管理平台可检测所述目标显示窗口是否是所述指定窗口阵列中的最后一个显示窗口、和/或所述目标显示窗口是否是所述指定窗口阵列中一行的最后一个显示窗口、和/或所述目标显示窗口是否是所述指定窗口阵列中一列的最后一个显示窗口。
可选的，在检测时，管理平台可基于当前待创建的目标显示窗口的编号确定当前是否创建指定窗口阵列中的最后一个显示窗口。例如，管理平台预先给指定窗口阵列中的待创建的显示窗口进行了编号，若当前待创建的目标显示窗口的编号是最后一个编号，则确定当前待创建的目标显示窗口是指定显示窗口阵列中的最后一个显示窗口。
当然，管理平台也可以依据已调整了的初始窗口区域的显示窗口的数量和显示窗口阵列中的显示窗口数量来确定当前目标显示窗口是否是指定窗口阵列中最后一个显示窗口，这里只是示例性地说明，不对其进行具体地限定。在本申请中，已调整了的初始窗口区域的显示窗口也被称为已确定的显示窗口。
当然，管理平台也可以基于本平台维护的目标显示窗口的编号，确定目标显示窗口是否为一行中的最后一个显示窗口，或者一列中的最后一个显示窗口。
比如，要创建3*4个显示窗口，则这12个显示窗口按照从左至右，从上至下的顺序依次编号为1、2、3、4、5、6、7、8、9、10、11、12。其中，编号4为第一行最后一个显示窗口，编号9是第一列最后一个显示窗口。
当管理平台要确定编号为4的显示窗口的初始窗口区域时，管理平台基于编号4，确定该显示窗口为第一行最后一个显示窗口。
当管理平台要确定编号为9的显示窗口的初始窗口区域时，管理平台基于编号9，确定该显示窗口为第一列最后一个显示窗口。
当然，管理平台也可依据已确定的显示窗口的数量和显示窗口阵列中的显示窗口数量，来确定目标显示窗口是否为一行中的最后一个显示窗口，或者一列中的最后一个显示窗口，这里只是示例性地说明，不对其进行具体地限定。
在所述目标显示窗口是指定显示窗口阵列中的最后一个显示窗口、和/或所述目标显示窗口是所述指定窗口阵列中一行的最后一个显示窗口、和/或所述目标显示窗口是所述指定窗口阵列中一列的最后一个显示窗口，则在确定电视墙的剩余窗口创建区域满足预设的窗口创建条件的情况下，管理平台执行所述确定待创建的目标显示窗口的初始窗口区域的步骤，即基于步骤501至步骤503来实现与该初始窗口区域对应的目标显示窗口的创建。
在所述目标显示窗口非所述指定窗口阵列中的最后一个显示窗口、和/或所述目标显示窗口非所述指定窗口阵列中一行的最后一个显示窗口、和/或所述目标显示窗口非所述指定窗口阵列中一列的最后一个显示窗口时，执行所述确定待创建的目标显示窗口的初始窗口区域的步骤，即基于步骤501至步骤503来实现与该初始窗口区域对应的目标显示窗口的创建。
其中，该预设的窗口创建条件包括：所述剩余窗口创建区域满足所述电视墙所支持的最小显示窗口的创建；和/或；所述剩余窗口创建区域的宽度大于待确定的初始窗口区域的左边界或右边界对应的预设范围的最大值、且所述剩余窗口创建区域的高度大于所述待确定的初始窗口区域的上边界或下边界对应的预设范围的最大值。
下面对“所述剩余窗口创建区域满足所述电视墙所支持的最小显示窗口的创建”进行举例说明。
假设电视墙所支持的最小显示窗口的尺寸为a*b，当剩余窗口创建区域的长与宽之积小于a*b时，则表明剩余窗口创建区域不满足所述电视墙所支持的最小显示窗口的创建。若当剩余窗口创建 区域的长与宽之积大于或等于a*b，则表明剩余窗口创建区域满足所述电视墙所支持的最小显示窗口的创建。
下面对“所述剩余窗口创建区域的宽度大于待确定的初始窗口区域的左边界或右边界对应的预设范围的最大值、且所述剩余窗口创建区域的高度大于所述待确定的初始窗口区域的上边界或下边界对应的预设范围的最大值”。
比如，假设显示窗口区域左右边界与物理输出区域的左右边界的边界距离在(0，L1)的范围内，会产生黑边；显示窗口区域上下边界与物理输出区域的上下边界的边界距离在(0，L2)的范围内，会产生黑边。在一实施例中，如果出现下述情况的至少之一：显示窗口区域左边界与物理输出区域的左边界或右边界的边界距离在(0，L1)的范围内，显示窗口区域右边界与物理输出区域的左边界或右边界的边界距离在(0，L1)的范围内，显示窗口区域上边界与物理输出区域的上边界或下边界的边界距离在(0，L2)的范围内，显示窗口区域下边界与物理输出区域的上边界或下边界的边界距离在(0，L2)的范围内，则会产生黑边。
若剩余窗口创建区域的宽度若小于L1和/或剩余窗口创建区域的高度小于L2，则表示剩余窗口创建区域的宽度和/或高度小于预设范围的最大值，则进一步表明剩余窗口创建区域不满足预设的窗口创建条件。
若剩余窗口创建区域的宽度若大于或等于L1且剩余窗口创建区域的高度大于或等于L2，则表示剩余窗口创建区域的宽度和/或高度大于或等于预设范围的最大值，则进一步表明剩余窗口创建区域满足预设的窗口创建条件。
此外，在本申请实施例中，在确定目标显示窗口是指定窗口阵列中最后一个显示窗口、和/或指定窗口阵列一行中最后一个显示窗口、和/或指定窗口阵列一列中最后一个显示窗口的情况下，若管理平台确定电视墙的剩余窗口创建区域不满足预设的窗口创建条件时，管理平台可发出告警信息，以提示无法创建指定窗口阵列中最后一个显示窗口、和/或无法创建指定窗口阵列一行中最后一个显示窗口、和/或无法创建指定窗口阵列一列中最后一个显示窗口。
2)步骤501的实现方式
在一种可选的实现方式中，在待创建的目标显示窗口为指定窗口阵列中的第一个显示窗口的情况下，管理平台可依据预设点在所述电视墙坐标系中的坐标，确定所述初始窗口区域。
其中，若管理平台坐标系与电视墙坐标系相同时，管理平台可直接依据预设点在电视墙坐标系中的坐标，确定所述初始窗口区域。
若管理平台坐标系与电视墙坐标系不同，且管理平台坐标系是由电视墙坐标系映射得来的，则管理平台可将预设点在所述电视墙坐标系中的坐标，转换为预设点在管理平台坐标系下的坐标，然后基于转换后的预设点的坐标，确定所述初始窗口区域。这里只是示例性地说明，不对其进行具体地限定。
其中，管理平台可基于当前待创建的目标显示窗口的编号来确定目标显示窗口是否为第一个显示窗口，或者依据已确定的显示窗口的数量来确定目标显示窗口是否为第一个显示窗口，这里只是示例性地说明，不对其进行具体地限定。
例如，假设在管理平台坐标系下，电视墙的左上角顶点作为原点，电视墙的上边界所在的线作为横坐标，电视墙右边界所在的线作为纵坐标。
假设在管理平台坐标系下，电视墙的左上角顶点的坐标为(0，0)、左下角顶点的坐标为(0，y 1)、右下角顶点的坐标为(x 1，y 1)、右上角顶点的坐标为(x 1，0)。
假设需要创建的显示窗口阵列为M*N。
假设在管理平台坐标系下，预设点为P 0，P 0的坐标为(x 0，y 0)。
管理平台可依据预设点，确定第一个显示窗口的初始窗口区域。比如，在管理平台坐标系下，管理平台可以以预设点P 0作为第一个显示窗口的初始窗口区域的左上角的坐标。第一个显示窗口区域的左下角作为(x 0，y 0+第一个显示窗口的高度)、第一显示窗口区域的右上角坐标为(x 0+第一个显示窗口的宽度，y 0)、第一显示窗口区域的右下角坐标为(x 0+第一个显示窗口的宽度，y 0+第一个显示窗口的高度)。
其中，第一个显示窗口的高度和宽度可以是管理平台自动计算，比如假设管理平台要建立M*N的显示窗口阵列，则管理平台要建立M行，每行N个显示窗口，所以每个显示窗口的宽度为x 1/N，高度为y 1/M。
此外，在本申请实施例中，每个显示窗口的宽度和高度还可以是由用户自行设定。
需要说明的是，管理平台上维护或者确定出的与坐标相关的信息(比如管理平台上确定出的窗口区域、维护的虚拟输出区域、计算出的第一边界和第二边界的距离、以及预设范围、预设点等)都是基于管理平台坐标系来确定的。而管理平台坐标系可以与电视墙坐标系相同，也可以是由电视墙坐标系映射得到的。下文不在赘述。
在另一种可选的实现方式中，在目标显示窗口为指定窗口阵列中的非第一个显示窗口的情况下，管理平台依据指定窗口阵列已确定的显示窗口对应的窗口区域，确定所述初始窗口区域。
在本申请实施例中，管理平台可检测当前待创建的目标显示窗口是否是当前行中的第一个显示窗口，所述当前行为指定窗口阵列中除第一行外的其他行。
在本申请实施例中，管理平台可以依据目标显示窗口的编号来确定该目标显示窗口是否是所述窗口阵列中除第一行外的其他行中的第一个显示窗口。比如，要创建3*4个显示窗口，则这12个显示窗口按照从左至右，从上至下的顺序依次编号为1、2、3、4、5、6、7、8、9、10、11、12。其中，编号5为第二行第一个显示窗口，编号9是第三行第一个显示窗口。
假设目标显示窗口为编号为5，则表明该目标显示窗口为第二行第一个目标显示窗口。
当然，管理平台还可以依据已确定的显示窗口的数量来确定该目标显示窗口是否是所述窗口阵列中除第一行外的其他行中的第一个显示窗口。比如，管理平台要创建3*4的显示窗口阵列，管理平台已成功调整了4个显示窗口的初始窗口区域，即管理平台已确定了4个显示窗口，当前待确定的目标显示窗口的初始窗口区域是第5个显示窗口的初始窗口区域，则可确定该目标显示窗口为第二行第一个显示窗口。
这里只是示例性地说明，不对其进行具体地限定。
在目标显示窗口为指定窗口阵列中当前行的第一个显示窗口的情况下，管理平台依据最新已确定的行中显示窗口对应的窗口区域，确定所述初始窗口区域。
其中，最新已确定的行是指除当前行外的最新已调整了初始窗口区域的行。
比如指定显示窗口阵列的显示窗口是按照从上到下，从左到右的顺序排列的，假设当前待创建的目标显示窗口是按照从上到下的方向的第二行的第一个显示窗口，则最新已确定的行是指定窗口阵列中按照从上到下的方向的第一行。
再比如，指定显示窗口阵列的显示窗口是按照从下到上，从左到右的顺序排列的，假设当前待创建的目标显示窗口是按照从上到下的方向的第三行的第一个显示窗口，则最新已确定的行是指定窗口阵列中按照从上到下的方向的第四行。
此外，在目标显示窗口为指定窗口阵列中当前行的第一个显示窗口的情况下，在依据最新已确定的行中显示窗口对应的窗口区域，确定所述初始窗口区域时，管理平台可依据最新已确定的行中的任意的显示窗口(比如第一个显示窗口，第二个显示窗口等)对应的窗口区域，确定所述初始窗口区域。
在一实施例中，在目标显示窗口为指定窗口阵列中当前行的第一个显示窗口的情况下，管理平台可依据最新已确定的行中的第一个显示窗口对应的窗口区域，确定所述初始窗口区域。
例如，如图3所示，假设待创建的目标显示窗口是第二行的第一个显示窗口，则管理平台可以依据第一行的第一个显示窗口的窗口区域，确定出第二行第一个显示窗口的初始窗口区域。
例如，管理平台可依据第一行的第一个显示窗口区域的左下角顶点作为第二行的第一个显示窗口的初始窗口区域的左上角顶点，再依据第二行的第一个显示窗口区域的宽和高，确定出第二行的第一个显示窗口的初始窗口区域的其他三个顶点坐标，确定方式如上文确定第一个显示窗口的初始窗口区域所示，这里不再赘述。
在所述目标显示窗口为当前行的非第一个显示窗口的情况下，管理平台可依据当前行中最新已确定的显示窗口，确定所述初始窗口区域。
例如，如图3所示，假设当前待创建的目标显示窗口是第二行的第二个显示窗口，则管理平台可以依据最新已确定的第二行的第一个显示窗口，确定出第二行第二个显示窗口的初始窗口区域。
比如，管理平台可依据第二行的第一个显示窗口的调整后的初始窗口区域的右上角顶点作为第二行的第二个显示窗口的初始窗口区域的左上角顶点，再依据第二行的第二个显示窗口区域的宽和高，确定出第二行的第二个显示窗口的初始窗口区域的其他三个顶点坐标，确定方式如上文确定第一个显示窗口的初始窗口区域所示，这里不再赘述。
步骤502：管理平台从与所述电视墙已被划分的多个物理输出区域对应的多个虚拟输出区域中确定与所述初始窗口区域具有交集的至少一个目标虚拟输出区域；所述多个物理输出区域与所述电视墙连接的解码设备上用于传输解码后视频流的输出口对应。
在实现时，管理平台可在所有虚拟输出区域中，确定出与初始窗口区域具有交集的至少一个虚拟输出区域，这里为了方便叙述，将与该初始窗口区域具有交集的至少一个虚拟输出区域称为目标虚拟输出区域。
例如，如图6A所示，在图6A所示的情况下，初始窗口区域在虚拟输出区域1中，虚拟输出区域1为目标虚拟输出区域。
例如，如图6B所示，在图6B所示的情况下，由于初始窗口区域与虚拟输出区域1和虚拟输出区域2均有交集，所以虚拟输出区域1和虚拟输出区域2都是目标虚拟输出区域。
步骤503：管理平台依据所述初始窗口区域和所述至少一个目标虚拟输出区域上相对应的边界之间的距离调整所述初始窗口区域，并将调整后的初始窗口区域发送给所述电视墙，以使所述电视墙依据调整后的初始窗口区域创建的目标显示窗口不产生窗口黑边。
在实现时，管理平台可确定目标边界对，所述目标边界对包括：位于初始窗口区域的第一边界，以及第一边界所在的目标虚拟输出区域中平行于所述第一边界的第二边界、所述第一边界和第二边界之间的距离在该第一边界对应的预设范围内。然后，管理平台可调整目标边界对中的第一边界，以使得所述调整后的第一边界与第二边界之间的距离不在该预设范围内；其中，所述预设范围表示黑边产生的范围。
在实现时，管理平台可以在确定出一个目标边界对后，就对该目标边界对的第一边界进行调整。然后再确定另一个目标边界对，再对另一个目标边界对中的第一边界进行调整。一个示例中，管理平台可以在确定出第一个目标边界对后，对该目标边界对的第一边界进行调整时，保持初始窗口区域大小不变，即需要将初始窗口区域的其余边界随第一边界的调整而调整，然后再确定还存在另一目标边界对时，对另一目标边界对中的第一边界进行调整，其中，对后一个第一边界调整时，保持已调整完的第一边界在该第一边界的被调整方向上不动。当然，在实际应用中，管理平台也可以在确定出所有目标边界对后，依次调整确定出的目标边界对中的第一边界，调整过程中，初始窗口区域大小可以适当改变。这里只是示例性地说明，不对其进行具体地限定。
下面分别对“确定目标边界对”和“调整目标边界对中的第一边界”进行详细地介绍。
步骤5031：管理平台确定目标边界对。
下面通过步骤A1至步骤A2对步骤5031进行详细地描述。
步骤A1：管理平台确定边界对。
这里为了方便叙述，将初始窗口区域中的边界称为第一边界，将目标虚拟输出区域中的边界称为第二边界。
在确定时，针对初始窗口区域中的每一第一边界，管理平台可从该第一边界所在的目标虚拟输出区域所有边界中，获取与该第一边界所在直线平行的边界，作为第二边界，然后将第一边界和第二边界组成一个边界对。
例如，如图6A所示，若第一边界是初始窗口区域的左边界，由于第一边界在虚拟输出区域1中，则将虚拟输出区域1中的左边界和/或右边界作为第二边界，并将该第一边界和第二边界组成一个边界对。
若第一边界是初始窗口区域的右边界，由于第一边界在虚拟输出区域1中，则将虚拟输出 区域1中的左边界和/或右边界作为第二边界，并将该第一边界和第二边界组成一个边界对。
若第一边界是初始窗口区域的上边界，由于第一边界在虚拟输出区域1中，则将虚拟输出区域1中的上边界和/或下边界作为第二边界，并将该第一边界和第二边界组成一个边界对。
若第一边界是初始窗口区域的下边界，由于第一边界在虚拟输出区域1中，则将虚拟输出区域1中的上边界和/或下边界作为第二边界，并将该第一边界和第二边界组成一个边界对。
再例如，如图6B所示，若第一边界是初始窗口区域的左边界，由于第一边界在虚拟输出区域3中，则将虚拟输出区域3中的左边界和/或右边界作为第二边界，并将该第一边界和第二边界组成一个边界对。
若第一边界是初始窗口区域的右边界，由于第一边界在虚拟输出区域2中，将虚拟输出区域2中的左边界和/或右边界作为第二边界，并将该第一边界和第二边界组成一个边界对。
若第一边界是初始窗口区域的上边界，由于第一边界在虚拟输出区域2和虚拟输出区域3中，则将虚拟输出区域2中的上边界和/或下边界作为第二边界、和/或将虚拟输出区域3中的上边界和/或下边界作为第二边界，并将该第一边界和第二边界组成一个边界对。
若第一边界是初始窗口区域的下边界，由于第一边界在虚拟输出区域2和虚拟输出区域3中，则将虚拟输出区域2中的上边界和/或下边界作为第二边界、和/或将虚拟输出区域3中的上边界和/或下边界作为第二边界，并将该第一边界和第二边界组成一个边界对。
步骤A2：管理平台确定确定出的边界对是否为目标边界对。
在实现时，管理平台可检测该确定出的边界对中的第一边界和第二边界之间的距离是否在该第一边界对应的预设范围内，若该确定出的边界对中的第一边界和第二边界之间的距离在该第一边界对应的预设范围内，则将该确定出的边界对确定为目标边界对。若该确定出的边界对中的第一边界和第二边界之间的距离不在该第一边界对应的预设范围内，则将确定出的边界对确定为非目标边界对。
其中，该预设范围就是产生黑边的范围。
下面举例说明下步骤A2。
例如，假设初始窗口区域的上、下边界对应的预设范围为(0，L2)。假设初始窗口区域的左、右边界对应的预设范围为(0，L1)。
例如，如图6A所示，假设边界对1中的第一边界为初始窗口区域的右边界，第二边界为虚拟输出区域1中的右边界，则管理平台可检测初始窗口区域的右边界与虚拟输出区域1中的右边界的距离是否在(0，L1)。在图6A中，由于初始窗口区域的右边界与虚拟输出区域1中的右边界的距离在(0，L1)，则边界对1为目标边界对。
再例如，如图6A所示，边界对2中的第一边界为初始窗口区域的上边界，第二边界为虚拟输出区域1中的上边界，则管理平台可检测初始窗口区域的上边界与虚拟输出区域1中的上边界的距离是否在(0，L2)。假设，初始窗口区域的上边界与虚拟输出区域1中的上边界的距离不在(0，L2)，则边界对2不是目标边界对。
再例如，如图6B所示，假设边界对3中的第一边界为初始窗口区域的右边界，第二边界为虚拟输出区域2中的左边界，则管理平台可检测初始窗口区域的右边界与虚拟输出区域2中的左边界的距离是否在(0，L1)。由于，在本例中，初始窗口区域的右边界与虚拟输出区域2中的左边界的距离在(0，L1)，所以边界对3是目标边界对。
在本申请实施例中，对于非目标边界对(即非目标边界对中的第一边界和第二边界之间的距离不在该第一边界对应的预设范围内)，管理平台可维持该边界对中的第一边界位置不变。
对于目标边界对，管理平台可依据步骤5032对该目标边界对中的第一边界进行调整。
步骤5032：管理平台调整目标边界对中的第一边界，以使得所述第一边界与第二边界之间的距离不在该预设范围内。
在实现时，假设第一边界对应的预设范围为(0，L)。其中，该预设范围为黑边产生的范围。当该第一边界是初始窗口区域的左边界和/或右边界时，该预设范围中的L为L1，当该第一边 界是初始窗口区域的上边界和/或下边界时，该预设范围中的L为L2。其中，L1与L2可以相同，也可以不同，这里不进行具体地限定。下面通过步骤B1至步骤B2对步骤5032进行详细地说明。
步骤B1：管理平台可确定第一吸附位置和第二吸附位置。
在实现时，管理平台可将该目标边界对中的第二边界所在的位置确定为第二吸附位置，将位于该第二边界所在的目标虚拟输出区域内、与第二吸附位置的距离为L的位置确定为第一吸附位置。
例如，如图6A所示，线2所在的位置为第二吸附位置，线1所在位置为第一吸附位置。
步骤B2：管理平台可确定第一边界对应的较近吸附位置，并将第一边界调整到与之对应的较近吸附位置上。其中，较近吸附位置是第一吸附位置与第二吸附位置中距离所述第一边界较近的吸附位置。
在实现时，管理平台在第一吸附位置和第二吸附位置中，选择与该第一边界距离较近的吸附位置作为较近吸附位置。比如，若第一边界与第一吸附位置距离近，则第一吸附位置为较近吸附位置，管理平台则可将该第一边界调整到第一吸附位置上。若该第一边界与第二吸附位置距离近，则第二吸附位置为较近吸附位置，管理平台可将该第一边界调整到第二吸附位置上。
在进行第一边界与两条吸附位置距离远近比较时，管理平台可基于L、以及第一边界与第二边界的距离d来确定。
若L-d<d，则表明第一吸附位置与第一边界更近，则将第一边界调整到第一吸附位置上。若L-d≥d，则表明第二吸附位置与第一边界更近，则将第一边界调整到第二吸附位置上。
例如，如图6A所示，假设初始窗口区域对应的预设范围为(0，L1)，假设初始窗口区域的右边界与虚拟输出区域1中的右边界的边界距离小于L1，则需要调整初始窗口区域的右边界。
在调整时，管理平台可在虚拟输出区域1中确定第一吸附位置(如图6A中的线1)和第二吸附位置(如图6A中的线2)，第二吸附位置设置在虚拟输出区域1中的右边界上，第一吸附位置设置在虚拟输出区域1内且与第二边界距离为L1的位置上。
假设初始窗口区域的右边界与虚拟输出区域1中的右边界的边界距离为d。
假设L1-d<d，则表明该初始窗口区域的右边界与第一吸附位置更近，则确定第一吸附位置为较近吸附位置，则将右边界调整到第一吸附位置上。
假设，在管理平台坐标系下，目标显示窗口的初始窗口区域的左上角坐标为(x 0，y 0)，左下角作为(x 0，y 0+目标显示窗口的高度)、右上角坐标为(x 0+目标显示窗口的宽度，y 0)、右下角坐标为(x 0+目标显示窗口的宽度，y 0+目标显示窗口的高度)。
则调整后的初始窗口区域的左上角坐标为(x 0，y 0)，左下角坐标为(x 0，y 0+目标显示窗口的高度)，右上角坐标为(x 0+目标显示窗口的宽度-(L1-d)，y 0)，右下角坐标为(x 0+目标显示窗口的宽度-(L1-d)，y 0+目标显示窗口的高度)。
例如，如图6B所示，初始窗口区域右边界对应的预设范围为(0，L1)，假设一个目标边界对中的第一边界为初始窗口区域的右边界，第二边界为虚拟输出区域2中的左边界，并且初始窗口区域的右边界、与该右边界所在的虚拟输出区域2中的左边界的边界距离小于L1。
在调整初始窗口区域的右边界时，管理平台可确定虚拟输出区域2中的第一吸附位置(如图6B中的线3)和第二吸附位置(如图6B中的线2)，第二吸附位置设置在虚拟输出区域2中的左边界上，第一吸附位置设置在虚拟输出区域2内、且与第二吸附位置距离为L1的位置上。
假设目标显示窗口的初始窗口区域的右边界与虚拟输出区域2中的左边界的边界距离为d。
假设L1-d<d，则表明该目标显示窗口的初始窗口区域的右边界与第一吸附位置更近，则确定该第一吸附位置为较近吸附位置，则将右边界调整到第一吸附位置(即线3)上。
假设，在管理平台坐标系下，目标显示窗口的初始窗口区域的左上角坐标为(x 0，y 0)，左下角作为(x 0，y 0+目标显示窗口的高度)、右上角坐标为(x 0+目标显示窗口的宽度，y 0)、右下角坐标为(x 0+目标显示窗口的宽度，y 0+目标显示窗口的高度)。
则调整后的初始窗口区域的左上角坐标为(x 0，y 0)，左下角作为(x 0，y 0+目标显示窗口 的高度)，右上角坐标为(x 0+目标显示窗口的宽度+(L1-d)，y 0)，右下角坐标为(x 0+目标显示窗口的宽度+(L1-d)，y 0+目标显示窗口的高度)。
此外，在本申请中，很容易出现初始窗口区域的不同边界对应同一较近吸附位置。
比如，如图7A图所示，假设初始窗口区域的左边界与虚拟输出区域1的右边界的边界距离小于L1，且初始窗口区域的左边界与线2的距离更近，则初始窗口区域的左边界对应的较近吸附位置为线2。
初始窗口区域的右边界与虚拟输出区域2的左边界的边界距离小于L1，且目标显示窗口的初始窗口区域的右边界与线2的距离更近，则目标显示窗口的初始窗口区域的右边界对应的较近吸附位置为线2。
这样就会产生目标显示窗口的初始窗口区域的左、右边界都对应同一较近吸附位置(即线2)。
因此，为了防止将初始窗口区域的不同边界都调整到同一较近吸附位置上，在本申请实施例中，管理平台在确定出目标边界对的第一边界的较近吸附位置后，管理平台在确定另一第一边界对应的较近吸附位置与所述第一边界对应的较近吸附位置相同时，将所述第一边界调整到该较近吸附位置上。
而对于另一第一边界，管理平台可将另一第一边界调整到其他位置上。在调整时，若该初始窗口区域的宽度或者高度大于L，管理平台则依据所述初始窗口区域的宽度或高度调整所述另一第一边界；若该初始窗口区域的宽度或者高度小于或等于L，管理平台则将所述另一第一边界调整到所述另一第一边界对应的较远吸附位置；其中，所述另一第一边界对应的较远吸附位置是另一第一边界对应的第一吸附位置与另一第一边界对应的第二吸附位置中距离所述另一第一边界较远的吸附位置。以图7A为例，在确定另一第一边界对应的较近吸附位置与所述第一边界对应的较近吸附位置相同时，将所述第一边界和所述另一第一边界调整到该较近吸附位置上，假设目标显示窗口的宽度为w，先将调整后的另一第一边界向所述另一第一边界对应的较远吸附位置平移距离w，确定所述平移后的另一第一边界是否未跨越所述另一第一边界对应的较远吸附位置，响应于确定所述平移后的边界未跨越所述另一第一边界对应的较远吸附位置，则将所述平移后的另一第一边界调整到所述另一第一边界对应的较远吸附位置；响应于确定所述平移后的边界已跨越所述另一第一边界对应的较远吸附位置，则不再进行吸附。
例如，如图7A所示，假设，目标边界对中的第一边界为目标显示窗口的初始窗口区域的左边界，第二边界为虚拟输出区域1的右边界。另一第一边界为目标显示窗口的初始窗口区域的右边界，另一第二边界为虚拟输出区域2的左边界。第一边界和另一第一边界对应的预设范围均为(0，L1)。假设另一第一边界对应的第一吸附位置为线2，另一第一边界对应的第二吸附位置为线3。
在本例中，目标显示窗口的初始窗口区域的左右边界对应的较近吸附位置均为线2。
在对该目标边界对中的第一边界进行调整时，管理平台可检测另一第一边界对应的较近吸附位置与该第一边界对应的较近吸附位置是否相同，在本例中，另一第一边界(即初始窗口区域的右边界)与该第一边界(即初始窗口区域的左边界)对应的较近吸附位置均为线2，所以管理平台最终可将该第一边界(即初始窗口区域的左边界)调整到线2上。
在本例中，对于另一第一边界(即初始窗口区域的右边界)，管理平台可检测到该目标显示窗口的宽度w小于L1。则将另一第一边界(即目标显示窗口的初始窗口区域的右边界)，如图7B所示，调整到较远吸附位置上(即线3)。
又例如，如图7C所示，假设，目标边界对中的第一边界为目标显示窗口的初始窗口区域的左边界，第二边界为虚拟输出区域1的右边界。另一第一边界为目标显示窗口的初始窗口区域的右边界，另一第二边界为虚拟输出区域2的左边界。第一边界对应的预设范围为(0，L1)，另一第一边界对应的预设范围为(0，L1’)，L1小于L1’。假设另一第一边界对应的第一吸附位置为线2，另一第一边界对应的第二吸附位置为线3。
在本例中，另一第一边界(即初始窗口区域的右边界)与该第一边界(即初始窗口区域的左边界)对应的较近吸附位置均为线2，所以管理平台最终可将该第一边界(即初始窗口区域的左边界)调整到线2上。对于另一第一边界(即初始窗口区域的右边界)，管理平台可检测到该目标显示窗口的宽度w小于L1’。则将另一第一边界(即目标显示窗口的初始窗口区域的右边界)，如 图7D所示，调整到较远吸附位置上(即线3)。
再例如，如图7E所示，假设，目标边界对中的第一边界为目标显示窗口的初始窗口区域的左边界，第二边界为虚拟输出区域1的右边界。另一第一边界为目标显示窗口的初始窗口区域的右边界，另一第二边界为虚拟输出区域2的左边界。第一边界的预设范围为(0，L1)，另一第一边界的预设范围为(0，L1’)，L1大于L1’。假设另一第一边界对应的第一吸附位置为线2，另一第一边界对应的第二吸附位置为线3。
在本例中，另一第一边界(即初始窗口区域的右边界)与该第一边界(即初始窗口区域的左边界)对应的较近吸附位置均为线2，所以管理平台最终可将该第一边界(即初始窗口区域的左边界)调整到线2上。对于另一第一边界(即初始窗口区域的右边界)，管理平台可检测到该目标显示窗口的宽度w大于等于L1’。则将另一第一边界(即目标显示窗口的初始窗口区域的右边界)，如图7F所示，向右调整到距离右边界为该目标显示窗口的宽度w的位置上。
需要说明的是，在本申请中，管理平台可以在确定出第一边界和另一边界对应的较近吸附位置相同时，就直接进行上述对第一边界和另一第一边界的调整。
当然在实际应用中，管理平台也可以将所有目标边界对中的第一边界调整到对应的较近吸附位置后。管理平台再针对每一第一边界，检测另一第一边界是否与该第一边界较近吸附位置相同，若相同，则按照上述调整另一第一边界的方式重新调整另一第一边界。这里只是示例性地说明，不对其进行具体地限定。
在一个示例中，管理平台可以对每个目标边界对中的第一边界调整，以使得所述第一边界与第二边界之间的距离不在预设范围内。具体地，调整每个目标边界对中的第一边界可以包括：
针对每两对目标边界对，其中，该两对目标边界对中的第一边界与另一第一边界互为初始窗口区域的左右边界或上下边界，若第一边界对应的较近吸附位置与另一第一边界对应的较近吸附位置不同，则将该第一边界和该另一第一边界分别调整到对应的较近吸附位置上；若第一边界对应的较近吸附位置与另一第一边界对应的较近吸附位置相同，则将该第一边界调整到该较近吸附位置上，将另一第一边界按照以下调整：若该初始窗口区域的宽度或者高度大于L，依据初始窗口区域的宽度或高度调整该另一第一边界；若该初始窗口区域的宽度或者高度小于或等于L，将该另一第一边界调整到该另一第一边界对应的较远吸附位置；其中，该另一第一边界对应的较远吸附位置是该另一第一边界对应的第一吸附位置与该另一第一边界对应的第二吸附位置中距离该另一第一边界较远的吸附位置。
由于调整后的初始窗口区域和目标虚拟输出区域中相对应的边界之间的距离在预设范围内，所以可以使得电视墙基于该调整后的初始窗口区域创建出的目标显示窗口不产生窗口黑边。
在本申请中，在目标显示窗口非第一个显示窗口的情况下，由于对至少一个显示窗口的初始窗口区域的边界进行了如前述的调整，如果目标显示窗口的初始窗口区域与虚拟输出区域序列中的最后一个虚拟输出区域、和/或所述虚拟输出区域阵列中一行的最后一个虚拟输出区域、和/或所述虚拟输出区域阵列中一列的最后一个虚拟输出区域具有交集，则可能出现无法创建该显示窗口的情况。
因此，在一种可选的实现方式中，管理平台可以检测所述目标显示窗口的初始窗口区域是否与虚拟输出区域序列中的最后一个虚拟输出区域、和/或所述虚拟输出区域阵列中一行的最后一个虚拟输出区域、和/或所述虚拟输出区域阵列中一列的最后一个虚拟输出区域具有交集。
若所述目标显示窗口的初始窗口区域与由所述多个虚拟输出区域组成的虚拟输出区域阵列中每一行的最后一个虚拟输出区域、以及所述虚拟输出区域阵列中每一列的最后一个虚拟输出区域没有交集，则从所述虚拟输出区域阵列中确定与所述初始窗口区域具有交集的至少一个目标虚拟输出区域。
若所述目标显示窗口的初始窗口区域与所述虚拟输出区域阵列中任一行的最后一个虚拟输出区域、或所述虚拟输出区域阵列中任一列的最后一个虚拟输出区域具有交集，则在确定所述电视墙的剩余窗口创建区域满足预设的窗口创建条件时，依据所述初始窗口区域与所述至少一个目标虚拟输出区域上相对应的边界之间的距离调整所述初始窗口区域。其中，所述预设的窗口创建条件与前述实施例中类似，在此不再赘述。
例如，如图8所示，虚拟输出区域3是其所在虚拟输出阵列某一行中最后一个虚拟输出区 域，初始窗口区域3与虚拟输出区域3具有交集，且所述剩余窗口创建区域满足所述创建窗口的条件。所以，初始窗口区域3可以根据步骤503进行调整，即将初始窗口3的右边界调整到线2。经过调整后，接下来对初始窗口区域4进行创建。初始窗口区域4与虚拟输出区域3具有交集，然而，此时，虚拟输出区域3已是该行中最后一个，且剩余的窗口创建区域只剩下线2。因此，初始窗口区域4无法进行创建，也不能根据步骤503继续进行调整。
此外在本申请实施例中，管理平台可将调整后的初始窗口区域发送给所述电视墙，以使所述电视墙依据调整后的初始窗口区域创建的目标显示窗口不产生窗口黑边。
在一种可选的实现方式中，管理平台可以在确定了所有调整后的初始显示窗口区域时，将所有调整后的初始显示窗口区域发送给电视墙，以由电视墙依据各调整后的初始显示窗口区域创建对应的显示窗口。
当然，在实际应用中，管理平台还可在每确定一个调整后的初始显示窗口区域后，就将该调整后的初始显示窗口区域发送给电视墙，以由该电视墙依据该调整后的初始窗口区域创建的目标显示窗口不产生窗口黑边。
这里只是示例性地说明，不对其进行具体地限定。
此外，还需要说明的是，管理平台在向电视墙发送的调整后的初始显示窗口可以是调整后的初始显示窗口的窗口顶点坐标。
在管理平台坐标系与电视墙坐标系一致的情况下，管理平台可直接将调整后的初始显示窗口的窗口顶点坐标发送给电视墙。
在管理平台坐标系与电视墙坐标系不一致的情况下，由于调整后的初始显示窗口的窗口顶点坐标是在管理平台坐标系下确定的坐标，所以管理平台需要将在本平台坐标系下确定出的调整后的初始显示窗口的窗口顶点坐标，转换为在电视墙坐标系下确定出的调整后的初始显示窗口的窗口顶点坐标，然后将在电视墙坐标系下确定出的调整后的初始显示窗口的窗口顶点坐标发送给电视墙。当然，管理平台也可将在本平台坐标系下确定出的调整后的初始显示窗口的窗口顶点坐标发送给电视墙，以由电视墙在管理平台坐标系下确定出的调整后的初始显示窗口的窗口顶点坐标，转换为在电视墙坐标系下确定出的调整后的初始显示窗口的窗口顶点坐标。这里只是示例性地说明，不对其进行具体地限定。
由上述描述可知，由于管理平台在创建显示窗口时，会确定出初始窗口区域，并依据初始窗口区域和与该初始窗口区域具有交集的目标虚拟输出区域上相对应的边界之间的距离调整所述初始窗口区域，以使得基于调整后的初始窗口区域创建出的显示窗口不会产生窗口黑边。
此外，本申请还提供一种电子设备，该电子设备可以是上述管理平台，可包括：可读存储介质和处理器；
