Member Function Documentation

virtual bool16 IJPEGImageWriteOptions::GetCustomHuff ( ) const

pure virtual

Retrieve the huffman encoding setting.

virtual JPEGEncoding IJPEGImageWriteOptions::GetEncoding ( ) const

pure virtual

Get counterpart to SetEncoding

virtual JPEGQuality IJPEGImageWriteOptions::GetJPEGQuality ( ) const

pure virtual

Get counterpart to SetJPEGQuality

virtual JPEGScanTabGroup IJPEGImageWriteOptions::GetScanTabGroup ( ) const

pure virtual

Obsolete

virtual void IJPEGImageWriteOptions::SetCustomHuff ( bool16 custom )

pure virtual

Set whether or not to use huffman encoding.

Parameters

custom - IN: Use huffman encoding?

virtual void IJPEGImageWriteOptions::SetEncoding ( JPEGEncoding encoding )

pure virtual

Set the encoding scheme

Parameters

encoding - IN: jpeg encoding scheme.

virtual void IJPEGImageWriteOptions::SetJPEGQuality ( JPEGQuality quality )

pure virtual

Set the compression quality. Has nothing to do with resolution or image quality.

Parameters

quality - IN: compression quality.

virtual void IJPEGImageWriteOptions::SetScanTabGroup ( JPEGScanTabGroup group )

pure virtual

Obsolete. You can safely ignore this method as the encoder does not actually use it.
