public CudaImage(int rows, int cols, bool continuous)

Parameters

rows int

The number of rows (height)

cols int

The number of columns (width)

continuous bool

Indicates if the data should be continuous

Methods

Clone(Stream)

Create a clone of this CudaImage

public CudaImage<TColor, TDepth> Clone(Stream stream)

Parameters

stream Stream

Use a Stream to call the function asynchronously (non-blocking) or null to call the function synchronously (blocking).

Returns

CudaImage<TColor, TDepth>

A clone of this CudaImage

Col(int)

Returns a CudaImage corresponding to the ith column of the CudaImage. The data is shared with the current Image.

public CudaImage<TColor, TDepth> Col(int i)

Parameters

i int

The column to be extracted

Returns

CudaImage<TColor, TDepth>

The ith column of the CudaImage

Remarks

The parent CudaImage should never be released before the returned CudaImage that represent the subregion

ColRange(int, int)

Returns a CudaImage corresponding to the [start end) columns of the CudaImage. The data is shared with the current Image.

public CudaImage<TColor, TDepth> ColRange(int start, int end)

Parameters

start int

The inclusive stating column to be extracted

end int

The exclusive ending column to be extracted

Returns

CudaImage<TColor, TDepth>

The [start end) columns of the CudaImage

Remarks

The parent CudaImage should never be released before the returned CudaImage that represent the subregion

ConvertFrom<TSrcColor, TSrcDepth>(CudaImage<TSrcColor, TSrcDepth>)

Convert the source image to the current image, if the size are different, the current image will be a resized version of the srcImage.

public void ConvertFrom<TSrcColor, TSrcDepth>(CudaImage<TSrcColor, TSrcDepth> srcImage) where TSrcColor : struct, IColor where TSrcDepth : new()

Parameters
