Syntax

public sealed class IndexedImageFrame<TPixel> : IDisposable where TPixel : unmanaged, IPixel<TPixel>

Type Parameters

Name	Description
TPixel	The pixel format.

Constructors

IndexedImageFrame(Configuration, int, int, ReadOnlyMemory<TPixel>)

Initializes a new instance of the IndexedImageFrame<TPixel> class.

Declaration

public IndexedImageFrame(Configuration configuration, int width, int height, ReadOnlyMemory<TPixel> palette)

Parameters

Type	Name	Description
Configuration	configuration	The configuration which allows altering default behaviour or extending the library.
int	width	The frame width.
int	height	The frame height.
ReadOnlyMemory<TPixel>	palette	The color palette.

Properties

Configuration

Gets the configuration which allows altering default behaviour or extending the library.

Declaration

public Configuration Configuration { get; }

Property Value

Type	Description
Configuration

Height

Gets the height of this IndexedImageFrame<TPixel>.

Declaration

public int Height { get; }

Property Value

Type	Description
int

Palette

Gets the color palette of this IndexedImageFrame<TPixel>.

Declaration

public ReadOnlyMemory<TPixel> Palette { get; }

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.

Declaration

public ReadOnlySpan<byte> DangerousGetRowSpan(int rowIndex)

Parameters

Type	Name	Description
int	rowIndex	The row index in the pixel buffer.

Returns

Type	Description
ReadOnlySpan<byte>	The pixel row as a ReadOnlySpan<T>.

Dispose()

Performs application-defined tasks associated with freeing, releasing, or resetting unmanaged resources.

Declaration

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.

Declaration

public Span<byte> GetWritablePixelRowSpanUnsafe(int rowIndex)

Parameters

Type	Name	Description
int	rowIndex	The row index in the pixel buffer.

Returns

Type	Description
Span<byte>	The pixel row as a Span<T>.
