Methods

DangerousGetRowSpan(int)

Gets the representation of the pixels as a ReadOnlySpan<T> of contiguous memory at row rowIndex beginning from the first pixel on that row.

WARNING: Disposing or leaking the underlying IndexedImageFrame<TPixel> while still working with it's Span<T> might lead to memory corruption.

public ReadOnlySpan<byte> DangerousGetRowSpan(int rowIndex)

Parameters

rowIndex int

The row index in the pixel buffer.

Returns

ReadOnlySpan<byte>

The pixel row as a ReadOnlySpan<T>.

Dispose()

public void Dispose()

GetWritablePixelRowSpanUnsafe(int)

Gets the representation of the pixels as a Span<T> of contiguous memory at row rowIndex beginning from the first pixel on that row.

Note: Values written to this span are not sanitized against the palette length. Care should be taken during assignment to prevent out-of-bounds errors.

public Span<byte> GetWritablePixelRowSpanUnsafe(int rowIndex)

Parameters

rowIndex int

The row index in the pixel buffer.

Returns

Span<byte>

The pixel row as a Span<T>.
