Halcon基础-判断图像是黑白还是彩色图像-count_channels

算子	count_channels
算子原型	count_channels(MultiChannelImage : : : Channels)
算子参数	MultiChannelImage ：要判断的图像 Channels：图像的通道数，通过此参数判断是黑白还是彩色

Halcon举例：

read_image (Vessel, 'vessel')
count_channels (Vessel, Channels)

C++举例：

Hobject img;
HTuple channels;
read_image(&img,"img");
count_channels(g_currentImg, &channels);

if (1 == channels[0].I())		//单通道黑白
{
}
else if (3 == channels[0].I())	//三通道彩色
{
}
