Function opencv::cudaimgproc::swap_channels

pub fn swap_channels(
    image: &mut dyn ToInputOutputArray, 
    dst_order: &[i32; 4], 
    stream: &mut Stream
) -> Result<()>

Exchanges the color channels of an image in-place.

Parameters

• image: Source image. Supports only CV_8UC4 type.
• dstOrder: Integer array describing how channel values are permutated. The n-th entry of the array contains the number of the channel that is stored in the n-th channel of the output image. E.g. Given an RGBA image, aDstOrder = [3,2,1,0] converts this to ABGR channel order.
• stream: Stream for the asynchronous version.

The methods support arbitrary permutations of the original channels, including replication.

C++ default parameters

• stream: Stream::Null()
