代码说明：

图像格式转换的源码，用于图像不同格式的转换，如转换公式为Gray(i,j)=0.11*R(i,j)+0.59*G(i,j)+0.3*B(i,j)，其中Gray(i,j)为转换后的黑白图像在（i,j）点处的灰度值，其中绿色所占的比重最大，所以转换时可以直接使用G值。 -The source image format converter for conversion of images in different formats, such as the conversion formula for the Gray (i, j) = 0.11* R (i, j)+ 0.59* G (i, j)+ 0.3* B ( i, j), which Gray (i, j) for the converted black and white images in the (i, j) point of the gray value, of which the largest share in the green, so conversion can be directly used when the G value.
