Abstract
一种拓扑图中图形的放大方法，所述方法包括：确定拓扑图的当前时刻的放大区域；确定所述放大区域内的图形对象；在所述放大区域中确定放大基准点，放大所述放大区域内的图形对象距离所述基准点的距离，并显示放大后的所述放大区域内的图形对象；还包括一种拓扑图中图形的放大装置。
Description
本发明涉及到拓扑图的放大技术，具体涉及一种拓扑图中图形的放大方法、装置与计算机存储介质。
网络管理系统中，网络拓扑图以图形化的方式展示了网络设备之间的连接关系，使网络维护人员对设备分布和设备状态信息一目了然。
基于特定缩放比率的拓扑图，维护人员可通过为拓扑图配置的放大镜对该拓扑图的局部网络拓扑结构进行查看，这种查看方式对于拓扑结构比较简单的网络来说比较适合，而对于拓扑结构比较复杂的网络，在有限的可视空间内，在同一个放大镜中展示的部分网元设备，往往会出现设备堆叠显示的情形，进而造成设备不易被分辨，设备图标、标签、告警及运行状态等信息不易被查看。
况且传统的放大镜是将局部拓扑图中包括的网元设备及链路等图形对象均进行等比例放大，虽然多数时候能够辨清网元的位置分布，但有时放大后的图形所显示的内容会出现不同程度的失真。
发明内容
为解决现有存在的技术问题，本发明实施例的在于提供一种拓扑图中图形的放大方法、装置与计算机存储介质，可避免放大后的显示内容出现失真及设备堆叠显示，保证对拓扑图中的放大图形的清晰显示。
本发明实施例的技术方案是这样实现的：

确定拓扑图的当前时刻的放大区域；
确定所述放大区域内的图形对象；
在所述放大区域中确定放大基准点，放大所述放大区域内的图形对象距离所述基准点的距离，并显示放大后的所述放大区域内的图形对象。
上述方案中，在所述显示放大后的所述放大区域内的图形对象之后，所述方法还包括：
存储当前时刻放大区域内的图形对象。
上述方案中，在所述确定所述放大区域内的图形对象之前，所述方法还包括：
比较当前时刻所述放大区域的图形对象与存储的前一时刻的图形对象是否存在有不相同的图形对象；
比较为存在有不相同的图形对象时，所述确定所述放大区域内的图形对象，包括：
将相同的图形对象及与不同于前一时刻的图形对象一并确定为当前时刻所述放大区域内的图形对象。
上述方案中，所述确定所述放大区域内的图形对象，包括：
将所述放大区域内的网元设备的完整或部分图标、和/或网元设备之间的链路的完整或部分图标、和/或所述网元设备属性信息对应的图标、和/或网元设备之间的链路属性信息对应的图标作为所述放大区域内的图形对象。

本发明实施例提供的拓扑图中图形的放大方法、装置与计算机存储介质，所述方法包括：确定拓扑图的当前时刻的放大区域；确定所述放大区域内的图形对象；在所述放大区域中确定放大基准点，放大所述放大区域内的图形对象距离所述基准点的距离，并显示放大后的所述放大区域内的图形对象。利用本发明实施例的技术方案，在对拓扑图的局部图形进行放大时，保持了图形对象之间的相对位置不变，放大了图形对象之间的绝对距离，如此，避免了放大后的显示内容出现失真及设备堆叠，保证了对拓扑图中的局部图形的清晰显示。
图1为本发明实施例的拓扑图中图形的放大方法的流程示意图；
图2(a)～2(c)为本发明一具体实施例示意图；
图3为本发明实施例的拓扑图中图形的放大方法的一具体实现流程示意图；
图4为本发明实施例拓扑图中图形的放大装置的组成结构示意图。
本发明实施例记载了一种拓扑图中图形的放大方法，如图1所示，所述方法包括：
步骤11：确定拓扑图的当前时刻的放大区域；
本发明实施例是基于具有特定缩放比率的拓扑图而实现的。当网络维护人员想要查看拓扑图中的某一区域时，通过输入设备如鼠标对该当前区域进行点击时，网络管理系统可获取对该当前区域的点击操作，并将该当前区域作为拓扑图中的当前时刻的放大区域；这里，将该放大区域称之为放大镜的可视区，即需要放大镜进行放大的区域。
步骤12：确定所述放大区域内的图形对象；
这里，所述图形对象包括：所述放大区域内的网元设备的完整图标或其部分图标、和/或网元设备之间的链路的完整图标或其部分的图标、和/或所述网元设备属性信息对应的图标、和/或网元设备之间的链路属性信息对应的图标；其中，所述属性信息包括：网元设备的标签、告警、运行状态等；相应的，所述属性信息对应的图标包括：标签图标、告警图标、运行状态图标。
需要说明的是：将出现在可视区内的网元设备称之为第一种网元设备；因链路两端通常连接有网元设备，存在有链路出现在可视区内而链路两端的网元设备出现在可视区外这种情况，称此类网元设备为第二种网元设备；
确定第一种网元设备的图形对象包括：将该网元设备的图标、标签、告警、运行状态等作为该网元设备的图形对象；并称此时该网元设备的图
形对象为该网元设备的完整图形对象；
确定第二种网元设备的图形对象包括：将该网元设备的图标作为该网元设备的图形对象；并称此时该网元设备的图形对象为该网元设备的精简图形对象；
确定出现在可视区的链路的图形对象包括：将该链路的图标、标签、告警、运行状态等作为该网元设备的图形对象。对于链路的图形对象没有完整图形对象与精简图形对象之分。
由于第二种网元设备出现在可视区外，所以第二种网元设备的图形对象不被放大显示，而确定的目的在于方便确定与之相连接的链路的位置和走向。
这里，对于网络管理系统而言，此步骤相当于对出现在可视区内的第一种网元设备进行完整图形对象的绘制进而方便了维护人员对网元设备信息的查看；而对出现在可视区外的第二种网元设备进行精简图形对象的绘制，进而方便确定链路的位置和走向；如此便可提高网络管理系统对放大区域的图形对象的绘制速度及减少该绘制过程对网络管理系统内存资源的占用。
步骤13：在所述放大区域中确定放大基准点，放大所述放大区域内的图形对象距离所述基准点的距离，并显示放大后的所述放大区域内的图形对象。
这里，当拓扑图中的放大镜制作成圆形时，由放大镜放大显示的放大区域也为圆形，那么就可选定放大区域的中心点即放大区域的圆心为该放大区域的放大基准点；并以该放大基准点为坐标原点，建立一个坐标系，在所述坐标系中，根据放大镜的缩放比率调整当前时刻放大区域中的每一个图形对象相对于基准点的横向距离和纵向距离。例如：当前时刻放大区域内包括有网元设备D的图形对象如网元设备D的图标；在以放大基准点
为原点建立的坐标系中，网元设备D的图标距离基准点的横向距离为a、纵向距离为b(a、b均为正整数)，放大镜的缩放比例为C(C为正整数)时，经调整即放大后的网元设备D的图标距离基准点的横向距离为Ca、纵向距离为Cb。由此可见，对可视区内的每一个图形对象距离所述基准点的横纵向距离的调整，也就相当于可视区内的图形对象之间的距离被放大C倍，如此，避免了网元设备的堆叠显示；同时，本发明实施例可通过对放大镜的缩放比例参数的调整实现对放大区域内容的清晰显示。
上述说明，是以放大镜为圆形，放大区域的圆心为放大基准点为例进行的说明，此外，本发明实施例也适用于放大镜为矩形、椭圆等形状。同时，放大区域的中心点所处位置没有出现网元设备的图形对象及链路的对象；此外，放大基准点的不仅可以是放大区域的中心点，还可以是放大区域内没有图形对象的其它任何位置。
如图1所示，所述方法还包括：
存储当前时刻放大区域内的图形对象。
这里，进行存储的目的在于因为在实际应用中，维护人员将对拓扑图进行至少一次的局部图形的查看，在多次查看过程中，由于确定的放大区域不同，进而确定的放大区域内的图形对象也存在有不同；所以，本发明实施例的方法还包括：
比较当前时刻所述放大区域的图形对象与存储的前一时刻的图形对象是否存在有不相同的图形对象；比较为存在有不相同的图形对象时，所述确定所述放大区域内的图形对象，包括：将相同的图形对象及与不同于前一时刻的图形对象一并确定为所述放大区域内的图形对象；然后放大所述图形对象距离基准点的距离并显示所述图形对象。
其中，与前一时刻的放大区域内出现的图形对象相比较，对于当前时刻可视区出现的新的网元设备，如果前一时刻存储有关于该新的网元设备
的精简图形对象，则删除该精简图形对象，并确定该新的网元设备的标签、告警、运行状态等连同该新的网元设备的图标一并作为当前时刻关于该新的网元设备的完整图形对象；对于当前时刻可视区出现的新的链路，将该链路的图标、标签、告警、运行状态等作为当前时刻关于该链路的完整图形对象。对于由链路连接的位于链路两端的任意一个网元设备，如果前一时刻出现在可视区，当前时刻不在可视区则删除该网元设备的完整图形对象，仅将所述网元设备的图标作为关于该网元设备的精简图形对象；如果前一时刻不在可视区，当前时刻在可视区，则删除前一时刻的关于该网元设备的精简图形对象，将该网元设备的标签、告警、运行状态等连同该网元设备的图标一并作为关于该网元设备的完整图形对象。
对于当前时刻没有出现在可视区的网元设备，而前一时刻出现在可视区的网元设备，删除存储的前一时刻关于该网元设备的完整图形对象；如果当前时刻的可视区存在有与该网元设备连接的链路，则需要将该网元设备的图标作为关于该网元设备的精简图形对象；对于前一时刻可视区出现的与链路有关的图形对象而当前时刻可视区没有出现的与该链路有关的图形对象时，删除前一时刻存储的关于该链路的图形对象，如果由该链路连接的位于该链路两端的任一网元设备在前一时刻存在有与该网元设备有关的精简图形对象，则删除该精简图形对象。
图2(a)为一网络拓扑图，图2(b)为时刻1时放大镜对网络拓扑图的局部显示；图2(c)为时刻2时放大镜对网络拓扑图的局部显示；图3为本发明实施例的拓扑图中图形的放大方法的实现流程示意图；下面结合图2(a)～图2(c)、图3对本发明实施例的技术方案作进一步说明。
步骤301：时刻1时，获取到对当前区域(区域A)的点击时，确定区域A为放大镜的当前放大区域，如图2(b)所示；
其中，区域A内出现的第一种网元设备包括以太网交换机、本地备份
存储；出现的链路包括链路0、链路1、链路2及链路3；出现的第二种网元设备包括服务器1、服务器2及交换机。
步骤302：确定区域A内的图形对象；
这里，需将以太网交换机的图标、标签、告警及运行状态作为关于以太网交换机的图形对象；将本地备份存储的图标、标签、告警及运行状态作为关于本地备份存储的图形对象；将链路0～链路3各自的图标、标签、告警及运行状态作为对应链路的图形对象；将服务器1的图标作为服务器1图形对象；将服务器2的图标作为服务器2的图形对象；将交换机的图标作为交换机的图形对象。其中，由于篇幅的限制，图2(b)代表着告警及运行状态的图标均未示意出。
步骤303：选取区域A的中心点为放大基准点，根据放大镜的缩放比率调整图形对象相对于基准点的距离。
这里，以基准点为原点，建立一个坐标系，并在该坐标系中，放大所有图形对象距离所述基准点的横向距离与纵向距离；在放大区域内的网元设备及链路之间的连接关系及相对位置不变的基础上，依据放大镜的缩放比率，分别对与以太网交换机、本地备份存储有关的图形对象相对于基准点的横向和纵向距离进行所述缩放比率倍的放大；网元设备的图标也被放大镜放大了缩放比率倍，连接网元设备之间的链路0～链路3的图标也被放大了缩放比率倍。网元设备之间的绝对距离被放大，使得在用放大镜查看区域A内的网元设备时，不会出现网元设备堆叠的情况，而且网元设备的图标也被放大避免了内容失真显示的情况。
步骤304：存储时刻1的区域A内的图形对象。
这里，在时刻1时存储的图形对象包括：关于以太网交换机、本地备份存储、链路0、链路1、链路2及链路3的图形对象；服务器1、服务器2以及交换机的图形对象。
步骤305：时刻2时，获取到对当前区域(区域B)的点击时，确定区域B为放大镜的当前放大区域，如图2(c)所示；
其中，区域B内的出现的第一种网元设备包括以太网交换机、交换机；出现的链路包括链路2、链路3、链路4、链路5及链路6；出现的第二种网元设备包括服务器1、服务器2及存储交换机。
步骤306：比较时刻2的区域B内出现的有关网元设备及链路的图形对象与时刻1的区域A内出现的有关网元设备及链路的图像对象是否有不同，比较为有不同时，执行步骤307；否则，将时刻1时存储的图形对象作为时刻2时区域B的图形对象，继续执行步骤308；
这里，交换机为出现在区域B中新的网元设备；链路4、链路5及链路6为出现在区域B中的新的链路；本地备份存储是出现在区域A且区域B中没有出现的网元设备。
步骤307：将有关网元设备及链路的相同的图形对象与不同的图形对象一并作为时刻2时区域B内的图形对象；
具体的，删除时刻1时存储的关于链路0、1的图形对象以及本地备份存储的图形对象；保留时刻1时存储的以太网交换机图形对象作为时刻2的关于以太网交换机的图形对象；保留时刻1时存储的链路2的图形对象作为时刻2的关于链路2的图形对象；保留时刻1时存储的链路3的图形对象作为时刻2的关于链路3的图形对象；保留时刻1时存储的服务器1的图形对象作为时刻2的关于服务器1的图形对象；保留时刻1时存储的服务器2的图形对象作为时刻2的关于服务器2的图形对象；
并将交换机的图标、标签、告警及运行状态作为时刻2的关于交换机的图形对象；将链路4～链路6各自的图标、标签、告警及运行状态作为对应链路的图形对象；并将存储交换机的图标作为关于交换机的图形对象；
其中，由于篇幅的限制，图2(c)中代表告警及运行状态的图标均未
示意出。
步骤308：选取区域B的中心点为基准点，根据放大镜的缩放比率调整区域B内的图形对象相对于基准点的距离。
这里，以区域B的中心点即圆心为原点，建立一个坐标系，在该坐标系中，放大区域B的图形对象距离所述原点的横向距离与纵向距离；在区域B内的网元设备及链路之间的连接关系及相对位置不变的基础上，依据放大镜的缩放比率，分别对与太网交换机、交换机的有关的图形对象相对于基准点的横向和纵向距离进行缩放比率倍的放大；以太网交换机、交换机的图标也被放大镜放大了缩放比率倍，连接网元设备之间的链路2～链路6的图标也被放大了缩放比率倍。
步骤309：存储时刻2的区域B的图形对象，以便与后续时刻可视区的图形对象作比较。
上述实施例中，比较时刻1的区域A与时刻2的区域B出现的网元设备与链路为不同，即时刻1、2时放大区域发生了变化；当比较出时刻1、2时的放大区域内出现的网元设备与链路没有发生变化时，即时刻1、2时确定的放大区域没有发生变化时，将时刻1时存储的图形对象作为时刻2时区域B的图形对象；并在时刻2时依据放大镜的缩放比率，放大并显示时刻1时存储的图形对象距离区域B的放大基准点的距离。
同时，本发明实施例还提供了一种计算机存储介质，所述计算机存储介质中存储有计算机可执行指令，所述计算机可执行指令用于执行前述的拓扑图中图形的放大方法。
基于上述拓扑图中图形的放大方法，本发明实施例还记载了一种拓扑图中图形的放大装置，如图4所示，所述装置包括：第一确定单元41、第二单元42、第三确定单元43、放大单元44以及显示单元45；其中，

其中，所述第二确定单元42，配置为将所述放大区域内的网元设备的完整或部分图标、和/或网元设备之间的链路的完整或部分图标、和/或所述网元设备属性信息对应的图标、和/或网元设备之间的链路属性信息对应的图标作为所述放大区域内的图形对象。
这里，在实际应用中，维护人员将对拓扑图进行至少一次的局部图形的查看，在多次查看过程中，由于每一次所述第一确定单元41确定的放大区域不同，进而使得第二确定单元42确定的放大区域内的图形对象也存在有不同；所以，在每次查看完放大后的图形对象后，由存储单元46对图形对象进行存储，存储的目的在于在相邻查看次数下，该相邻查看次数下的放大区域内的图形对象可能存在有相同，也可能存在有不同。
所述装置还包括：比较单元47，配置为比较当前时刻所述放大区域的图形对象与存储的前一时刻的图形对象是否存在有不相同的图形对象；比较为存在有不相同的图形对象时，触发所述第二确定单元42；
相应的，所述第二确定单元42，配置为将相同的图形对象及与不同于前一时刻的图形对象一并确定为所述放大区域内的图形对象；
所述第三确定单元43，配置为确定放大区域的中心点为所述放大区域的放大区域；

坐标系，根据设置的缩放比率调整所述放大区域内的图形对象相对于基准点的横向和纵向距离；
所述显示单元45，配置为显示放大后的所述放大区域内的图形对象。
具体的，所述第二确定单元42对于当前时刻可视区出现的新的网元设备，如果前一时刻存储有关于该新的网元设备的精简图形对象，则删除该精简图形对象，并确定该新的网元设备的标签、告警、运行状态等连同该新的网元设备的图标一并作为当前时刻关于该新的网元设备的完整图形对象；对于当前时刻可视区出现的新的链路，所述第二确定单元42将该链路的图标、标签、告警、运行状态等作为当前时刻关于该链路的完整图形对象。对于由链路连接的位于链路两端的任意一个网元设备，如果前一时刻出现在可视区，当前时刻不在可视区则删除该网元设备的完整图形对象，所述第二确定单元42仅将所述网元设备的图标作为关于该网元设备的精简图形对象；如果前一时刻不在可视区，当前时刻在可视区，则所述第二确定单元42删除前一时刻的关于该网元设备的精简图形对象，将该网元设备的标签、告警、运行状态等连同该网元设备的图标一并作为关于该网元设备的完整图形对象。
对于当前时刻没有出现在可视区的网元设备，而前一时刻出现在可视区的网元设备，所述第二确定单元42删除存储的前一时刻关于该网元设备的完整图形对象；如果当前时刻的可视区存在有与该网元设备连接的链路，所述第二确定单元42将该网元设备的图标作为关于该网元设备的精简图形对象；对于前一时刻可视区出现的与链路有关的图形对象而当前时刻可视区没有出现的与该链路有关的图形对象时，所述第二确定单元42删除前一时刻存储的关于该链路的图形对象；如果由该链路连接的位于该链路两端的任一网元设备在前一时刻存在有与该网元设备有关的精简图形对象，则删除该精简图形对象。
在本实施例中，所涉及到的完整图形对象、精简图形对象、第一种网元设备、第二种网元设备等概念请参见前述方法中的说明，这里不再赘述。
下面结合图2(a)～2(c)对本发明实施例作进一步说明。

本发明实施例提供的拓扑图中图形的放大方法、装置及计算机存储介质，确定拓扑图的当前时刻的放大区域；确定所述放大区域内的图形对象；在所述放大区域中确定放大基准点，放大所述放大区域内的图形对象距离所述基准点的距离，并显示放大后的所述放大区域内的图形对象。利用本发明实施例的技术方案，在对拓扑图的局部图形进行放大时，保持了图形对象之间的相对位置不变，放大了图形对象之间的绝对距离，如此，避免了放大后的显示内容出现失真及设备堆叠显示，保证了对拓扑图中的局部图形的清晰显示。
