Description
本发明涉及计算机软件技术领域，特别是涉及一种绘制图形的方法和系统。
绘图软件在绘制图形时，一般会给定一些使得图形之间能够连接的绘图方法，使所绘图形严格满足一定的精度要求。
在现有方案中，在绘制线条时，一般采用的方案是，当要绘制相互靠近或者有接触的图形时，例如两根相衔接的线，则放大界面，确保两线衔接完全，绘制完后，为了能有一个更宽广的视野，又需要缩小界面；该方案中，用户需要不断的手动操作，来完成界面的放大、缩小操作，使得操作繁琐、不够方便；为了解决手动操作的问题，出现了自动吸附方案，即当线相接近时，线的端点便相吸附，虽然不用频繁进行手动操作，但用户无法绘制相接近而不相吸附的线，而且，当期望从某根线段上某点开始绘制新的线段时，此时，该方案无法确保其准确性，导致绘制效果较差。
发明内容
基于此，有必要针对上述操作繁琐、绘制效果较差的问题，提供一种绘制图形的方法和系统。
一种绘制图形的方法，包括如下步骤：
在绘制图形过程中，获取绘制操作点当前的位置信息；
根据所述位置信息获取所述操作点预设范围内的图像；
将所述图像发送至预设的图像显示装置上，并通过所述图像显示装置进行预设比例的放大显示；
根据图像显示装置显示的图像进行图形绘制。
一种绘制图形的系统，包括：
位置获取模块，用于在绘制图形过程中，获取绘制操作点当前的位置信息；
图像获取模块，用于根据所述位置信息获取所述操作点预设范围内的图像；
放大显示模块，用于将所述图像发送至预设的图像显示装置上，并通过所述图像显示装置进行预设比例的放大显示；
图形绘制模块，用于根据图像显示装置显示的图像进行图形绘制。
上述绘制图形的方法和系统，可以实时获取绘制操作点当前的位置信息，并根据所述位置信息获取操作点预设范围内的图像，将获取到的图形发送至预设的图像显示装置上，并通过所述图像显示装置进行预设比例的放大显示，从而使得用户可以根据放大的图像来进行绘制图形。本发明方案是对绘制操作点预设范围内的图像进行放大，不是对整个界面都进行放大，不需要再从整个放大的绘图界面定位实时的操作点，可以直接定位到正在绘图的小区域内，不影响图形绘制过程，提高效率，并且能够确保绘制的准确性。
图1为一个实施例的绘制图形的方法流程图；
图2为一个实施例的放大显示操作示意图；
图3为一个实施例的绘制图形的系统结构示意图。
下面结合附图对本发明的绘制图形的方法和系统的具体实施方式作详细描述。
参考图1所示，图1为一个实施例的绘制图形的方法流程图，包括如下步骤：
S110：在绘制图形过程中，获取绘制操作点当前的位置信息。
在本步骤中，可以在绘制图形过程中，通过获取绘制操作点当前的位置信息，其中，所述操作点可以为鼠标点、光标点或者是触摸点等；位置信息可以包括操作点在绘图界面中所处的直角坐标系的坐标值。
在一个实施例中，在步骤S110之前，还可以包括：
S100：在绘图软件启动时，启动所述图像显示装置和监视器；其中，所述
监视器用于侦听绘制图形的输入操作信息；另外，也可以在接收到设定的开启指令输入时，启动所述图像显示装置和监视器。
在上述实施例的方案中，所述监视器用于侦听绘制图形的输入操作信息，如侦听系统信息，以获取人体输入设备输入事件(消息)；图像显示装置和监视器可以根据需要决定是否启动，可以设置图像显示装置和监视器在绘图软件启动时自动启动，也可以设置为默认不自启动模式，在接收到相应的启动指令时，才开启图像显示装置和监视器。可以通过设置在绘图界面上对应的启动按钮、鼠标的右击或键盘上，利用预先设定的快捷键操作来输入启动指令。
S120：根据所述位置信息获取所述操作点预设范围内的图像。
在本步骤中，可以通过截图方式来获取操作点一定范围内的图像，预设范围大小可以根据需要预先设定，例如，以操作点为中心选取一合适范围，一般情况下，该范围选取综合考虑足够大以能够显示足够的信息，但又要限定一定大小以不至于影响绘制界面上其他部分显示的内容。
在一个实施例中，步骤S120的根据所述位置信息获取所述操作点预设范围内的图像的过程可以包括：通过系统应用程序接口调用系统截图工具，利用所述系统截图工具截取所述操作点预设范围内的图像。
例如，在Windows、Linux、Unix等多种操作系统下，直接调用系统自带的截图工具，这些截图工具稳定性非常好，并且可以很方便的通过相应的系统应用程序接口进行调用。
在另一个实施例中，步骤S120的根据所述位置信息获取所述操作点预设范围内的图像的过程，也可以通过第三方截图控件调用第三方截图工具，利用所述第三方截图工具截取所述操作点预设范围内的图像。即调用系统上安装的第三方截图工具来进行图像的截取。
作为一个实施例，所述的预设范围可以为以绘制操作点为中心的设定半径的圆形，对设定半径的圆形进行设定比例压缩的椭圆形、设定面积的四边形或多边形等。
进一步的，可以根据用户的需要预先设定预设范围的形状，在绘图过程中进行调用。并且还可以进一步设置下拉菜单及选择按钮，使得用户可以通过点
击菜单上的预设范围形状按钮来打开下拉菜单，在下拉菜单里中选择所需的形状；也可以设置通过鼠标快捷键对预设的范围形状进行选择和切换。
S130：将所述图像发送至预设的图像显示装置上，并通过所述图像显示装置进行预设比例的放大显示。
在本步骤中，可以首先顶层设置一个显示的窗口，构建一个具有设定比例放大显示的图像显示装置，将前面步骤S20中截图的图像发送至图像显示装置上进行相应比例的放大，然后显示在界面上，这样，用户就可以根据放大显示的图像，来对相应位置进行精确的图形绘制，并且不会影响到绘制界面其它部分图形的显示。
在一个实施例中，本发明绘制图形的方法还可以包括：获取用户输入的比例调整值，根据所述比例调整值对图像显示装置的显示比例进行调整。
上述实施例，在对于精确度要求较高的绘图情况下，可以适当增大放大比例，从而可以使得显示更加细腻；此外，对于用户输入的比例调整值的方式，可以设置放大比例值输入框或者滑动条，这样用户可以手动输入放大比例值或者滑动改变图像显示装置的显示比例。
在一个实施例中，对于图像显示装置的设置位置，一般可以设置在操作点的上、下、左、右或左上、左下、右上、右下等方位；考虑到操作点位置处于界面边缘处时，此时可以考虑将放大后的图像调整到其他位置显示，而不至于超出界面。
在一个实施例中，在步骤S130的将所述图像发送至预设的显示装置上的步骤之前还可以包括：判断所述绘制操作点预设范围内是否存在已绘制的图形，若存在，则启动图像显示装置，然后再将所述图像发送至所述图像显示装置上。
上述实施例的方案，考虑到并非每个位置都是需要进行放大显示，因此，本申请在此设置了一种判断手段，在进行绘制图形时，如果绘制过程中周围并没有已绘制好的图形，说明没有与其他图形有影响，而当出现有已绘制好的图形时，例如有两根相衔接的线时，就启动图像显示装置来放大显示截取的图像；另外，在绘制一段图形后，如果周围又出现没有已绘制好的其他图形，此时又可以关闭图像显示装置，以减少对绘制界面的影响。
S140：根据图像显示装置显示的图像进行图形绘制。
在本步骤中，用户可以根据放大后的图像来指导图形的绘制，能很方便的进行图形的精确绘制，可以解决诸如图形之间的精确连接或非常接近但不相连等的精确绘制情况。
在一个实施例中，本发明绘制图形的方法还可以包括：获取用户输入的分辨率调整值，根据所述分辨率调整值调整所述图像显示装置的分辨率。
上述实施例的方案，设置了图像显示装置的分辨率调整功能，可以通过用户输入相应分辨率调整值，根据该分辨率调整值来调整图像显示装置大小的方式实现。例如，可以根据显示屏、绘图界面的尺寸调整需要获取的以操作点为中心的区域范围，也可以通过设置区域范围的相应参数，如半径、面积等来调整区域范围的大小。
基于上述实施例的技术方案，放大后的图像为操作点附近范围的局部放大，因此，不需要再从整个放大的绘图界面定位实时的绘图操作点，可以直接定位到正在绘图的小区域内，不影响图形绘制过程，提高效率，并且能够确保绘制的准确性。
下面阐述基于本发明技术的一应用实例，参考图2所示，图2为一个实施例的放大显示操作示意图。以绘制“C”、“V”、“T”三个字母为例，在绘制“C”、“V”和“T”的上部分“—”时，绘制操作点预设范围没有已绘制的其他图形，则可以不对其范围内的图像进行放大；
接下来绘制字母“T”的下半部分即竖线(虚线部分)时，通过对图像检测，可以得到绘制操作点预设范围存在已绘制“T”的上部分“—”图形，获取预设范围内图像进行放大，从而方便用户实时绘制的图形与已绘制的图形进行连接、靠近等需要精确的操作。
通过上述有选择性的进行图像的放大显示，既可以节约系统资源，也可以在满足精确绘图的条件下，尽可能少的显示放大的图像，避免分散用户绘制时的注意力，提高绘图效率。
综合上述实施例的技术方案，在绘制图形时具有如下明显优点：
第一、对绘制操作点预设范围内的图像进行局部放大，不需要再从整个放
大的绘图界面定位实时的操作点，可以直接定位到正在绘图的小区域内，不影响图形绘制过程，提高效率，并且能够确保绘制的准确性。
第二，有选择性的对绘制操作点的图像进行放大，既可以节约系统资源，也可以在满足精确绘图的条件下，尽可能少的显示放大的图像，避免分散绘制时的注意力，提高绘图效率。
第三、充分考虑了绘图操作的实际情况，能够在绘图过程中对显示范围、显示形状、显示位置、显示分辨率进行随时调整，使得绘图过程、绘图界面更友好、更人性化。
