Examples

// JPEG-LS (.jls) is lossless or near-lossless; WithExtendedFormats() registers it too.
EgamiContext context = EgamiContext.Default.WithJpegLs();
using Raster duck = Raster.Load("duck.png", context);
duck.Save("duck.jls");

// Load gives the natural pixel type: Gray8 or Gray16, GrayAlpha, Rgb or Rgba, 8 or 16 bits as stored.
using Raster back = Raster.Load("duck.jls", context);
if (back.Metadata.FormatDetails is JpegLsDetails jls)
{
    Console.WriteLine($"NEAR {jls.Near}, {jls.Interleave}, {jls.BitsPerSample} bits, {jls.Components} components, {jls.ColorTransform}");
}

Properties

BitsPerSample

Gets or sets the bits of a stored sample, 2 to 16. Fewer than 8 or 16 are scaled to the pixel's full range on load.

public int BitsPerSample { get; set; }

Property Value

int

ColorTransform

Gets or sets the colour transform the file was coded with.

public JpegLsColorTransform ColorTransform { get; set; }

Property Value

JpegLsColorTransform

Components

Gets or sets the number of components the file stores.

public int Components { get; set; }

Property Value

int

Interleave

Gets or sets how the components were interleaved.

public JpegLsInterleave Interleave { get; set; }

Property Value

JpegLsInterleave

Near

Gets or sets the largest error of a sample: 0 when the file is lossless. The writer writes it back unless Near says otherwise.

public int Near { get; set; }

Property Value

int

Palettized

Gets or sets whether the samples were indices into a mapping table (a palette) that gave the pixels.

public bool Palettized { get; set; }

Property Value

bool

Methods

Copy()

Returns a deep copy.

public override FormatDetails Copy()

Returns

FormatDetails

The copy.
