企业官网建设流程全解析

目标：显示当前页面的所有颜色数量

结果：

一、控件设置

1、CogToolBlock

因为图片不只有一张，并且保险丝的数量和位置也不确定，所以需要编写脚本，通过CogPMAlignTool定位，然后将定位的XY坐标传输给CogCompositeColorMatchTool，最后通过脚本，遍历出所有的保险丝位置，然后判断颜色

外部只写一个控件，就是CogToolBlock

接下来进入CogToolBlock，开始配置其他控件

所有控件：

2、CogImageCovertTool

因为CogPMAlignTool只能处理灰度图，所以通过CogImageCovertTool转换为灰度图后，再将转换后的图传入CogPMAlignTool，进行位置判断。直接连线即可，不需要打开，自动转换

3、CogPMAlignTool

双击进入此控件

4、CogCompositeColorMatchTool

双击进入控件

二、代码设置

1、基础配置

Region.(Cognex.VisionPro.CogRectangleAffine).CenterX
Region.(Cognex.VisionPro.CogRectangleAffine).CenterY
Region.(Cognex.VisionPro.CogRectangleAffine).Rotation
上面这三个仅作演示，不需要连接或添加终端，使用默认的CogCompositeColorMatchTool1工具即可

2、代码
