Examples

// A PDF that names its own color space wants the codestream's components as stored.
using Raster components = Raster.Load(jpxStream, options: new Jpeg2000ReaderOptions { Components = Jpeg2000Components.Raw });

// A quick preview of a layered file: only its first quality layer, chroma repeated as OpenJPEG does.
using Raster preview = Raster.Load("photo.jp2", options: new Jpeg2000ReaderOptions { MaxQualityLayers = 1, FastUpsampling = true });

Properties

Components

Gets what the pixels are: Color (the default) applies palettes, channel definitions and color spaces; Raw returns the codestream's components as stored, for a PDF that names its own color space.

public Jpeg2000Components Components { get; init; }

Property Value

Jpeg2000Components

FastUpsampling

Gets whether subsampled chroma is repeated over the pixels it covers, as OpenJPEG does, instead of interpolated at its siting (the default).

public bool FastUpsampling { get; init; }

Property Value

bool

MaxQualityLayers

Gets how many quality layers to decode, for a quick preview of a layered file, or null (the default) for all of them.

public int? MaxQualityLayers { get; init; }

Property Value

int?
