在HDevelop中

dev_update_off()

read_image (Image, 'D:/bb/tu/1.jpg')
rgb1_to_gray(Image,Image1)
*将RGB图像转换为灰度图像

gray_erosion_rect (Image1, ImageMin, 5, 5)
*图像腐蚀-->效果：增加暗部，减少亮部
*参数1：灰度值图像
*参数2：输出图像
*参数3和参数4：结构元的宽和高


get_image_size (Image1, Width, Height)
dev_open_window(10,10,Width, Height,'black',WindowHandle)
dev_display(Image1)
dev_open_window(10,100,Width, Height,'black',WindowHandle1)
dev_display(ImageMin)

 

 

 

在QtCreator中

    Rgb1ToGray(ho_Image, &ho_Image1);
    //将RGB图像转换为灰度图像

    GrayErosionRect(ho_Image1, &ho_ImageMin, 5, 5);
    //图像腐蚀-->效果：增加暗部，减少亮部
    //参数1：灰度值图像
    //参数2：输出图像
    //参数3和参数4：结构元的宽和高


    GetImageSize(ho_Image1, &hv_Width, &hv_Height);
