Constructors

public JpegFrameEncode(nint nativePtr)

Parameters

nativePtr nint

Methods

GetAcHuffmanTable(int, int, out JpegAcHuffmanTable)

Retrieves a copy of the AC Huffman table for the specified scan and table.

public void GetAcHuffmanTable(int scanIndex, int tableIndex, out JpegAcHuffmanTable acHuffmanTableRef)

Parameters

scanIndex int

The zero-based index of the scan for which data is retrieved.

tableIndex int

The index of the AC Huffman table to retrieve.

acHuffmanTableRef JpegAcHuffmanTable

A reference that receives the table data. This parameter must not be null.

GetDcHuffmanTable(int, int, out JpegDeviceContextHuffmanTable)

Retrieves a copy of the DC Huffman table for the specified scan and table.

public void GetDcHuffmanTable(int scanIndex, int tableIndex, out JpegDeviceContextHuffmanTable dcHuffmanTableRef)

Parameters

scanIndex int

The zero-based index of the scan for which data is retrieved.

tableIndex int

The index of the DC Huffman table to retrieve.

dcHuffmanTableRef JpegDeviceContextHuffmanTable

A reference that receives the table data. This parameter must not be null.

GetQuantizationTable(int, int, out JpegQuantizationTable)

Retrieves a copy of the quantization table.

public void GetQuantizationTable(int scanIndex, int tableIndex, out JpegQuantizationTable quantizationTableRef)

Parameters

scanIndex int

The zero-based index of the scan for which data is retrieved.

tableIndex int

The index of the quantization table to retrieve.

quantizationTableRef JpegQuantizationTable

A reference that receives the table data. This parameter must not be null.

WriteScan(int, byte[])

Writes scan data to a JPEG frame.

public void WriteScan(int scanData, byte[] scanDataRef)

Parameters

scanData int

The size of the data in the pbScanData parameter.

scanDataRef byte[]

The scan data to write.

Remarks

WriteScan may be called multiple times. Each call appends the scan data specified to any previous scan data. Complete the scan by calling IWICBitmapFrameEncode::Commit.

Any calls to set encoder parameters or image metadata that will appear before the scan data in the resulting JPEG file must be completed before the first call to this method. This includes calls to IWICBitmapFrameEncode::SetColorContexts , IWICBitmapFrameEncode::SetPalette, IWICBitmapFrameEncode::SetPixelFormat, IWICBitmapFrameEncode::SetResolution, and IWICBitmapFrameEncode::SetThumbnail. IWICBitmapFrameEncode::SetSize is required as it has no default value for encoded image size.
