Syntax

public class EncodedImageData

Constructors

EncodedImageData(Byte[], Byte[], Int32, Int32, Int32, String, String[])

Create an image descriptor from encoded bytes with an optional alpha channel matching size/bits/filters.

Declaration
public EncodedImageData(byte[] data, byte[] alphaChannel, int bitsPerComponent, int width, int height, string colorSpace, string[] filters)
Parameters
System.Byte[] data

The data.
System.Byte[] alphaChannel

The alpha channel data. This data should be encoded with same bitsPerComponent, width, height and filters as the image data. The colorspace of the alpha channel is not related to the colorspace of the image data and the alpha data colorspace is always DeviceGray.
System.Int32 bitsPerComponent

The bits per component.
System.Int32 width

The width.
System.Int32 height

The height.
System.String colorSpace

The color space.
System.String[] filters

The filters.

EncodedImageData(Byte[], Int32, Int32, Int32, String, String[])

Create an image descriptor from encoded bytes without an alpha channel.

Declaration
public EncodedImageData(byte[] data, int bitsPerComponent, int width, int height, string colorSpace, string[] filters)
Parameters
System.Byte[] data

The data.
System.Int32 bitsPerComponent

The bits per component.
System.Int32 width

The width.
System.Int32 height

The height.
System.String colorSpace

The color space.
System.String[] filters

The filters.
