问题描述

如何使其变为粗体"并更改颜色?有人可以帮助我吗?我尝试了很多次，但仍然无法正常工作.

 Core.putText(mRgba, "Result : " +
            	contours.size(), new org.opencv.core.Point(0, 300),
            	Core.FONT_HERSHEY_SIMPLEX, 2.6f, new Scalar(255, 255, 0))

解决方案

阅读文档:两者都有参数.

public static void putText(Mat img,
    java.lang.String text,
    Point org,
    int fontFace,
    double fontScale,
    Scalar color,
    int thickness)

然后:

Core.putText(mRgba, 
    "Result : " + contours.size(),         
    new org.opencv.core.Point(0, 300),    
    Core.FONT_HERSHEY_SIMPLEX,         
    2.6f,                             
    new Scalar(255, 255, 0), // color in BGR format, you should change this one
    2 // thickness (can be used to achieve bold)
)

How to make it "Bold" and change color ? somebody can help me ? I try many times but still not working.

Core.putText(mRgba, "Result : " +
            	contours.size(), new org.opencv.core.Point(0, 300),
            	Core.FONT_HERSHEY_SIMPLEX, 2.6f, new Scalar(255, 255, 0))

解决方案

Read the documentation: you have parameters for both of them.

public static void putText(Mat img,
    java.lang.String text,
    Point org,
    int fontFace,
    double fontScale,
    Scalar color,
    int thickness)

Then:

Core.putText(mRgba, 
    "Result : " + contours.size(),         
    new org.opencv.core.Point(0, 300),    
    Core.FONT_HERSHEY_SIMPLEX,         
    2.6f,                             
    new Scalar(255, 255, 0), // color in BGR format, you should change this one
    2 // thickness (can be used to achieve bold)
)
