nn::jpeg::CTR::EncoderOption Enumerated Type

enum EncoderOption;

Value	Description
JPEG_ENCODER_OPTION_NONE
JPEG_ENCODER_OPTION_OMIT_APP1
JPEG_ENCODER_OPTION_OMIT_DHT

Options used when encoding.

The default value is JPEG_ENCODER_OPTION_NONE (0).

You can specify values that are the bitwise OR of these constants by using JpegMpEncoder::SetOption.

• JPEG_ENCODER_OPTION_NONE
  Equal to 0, you can clear options by specifying this option.

• JPEG_ENCODER_OPTION_OMIT_APP1
  If thumbnails are not attached, APP1 is not recorded. (If thumbnails are to be attached, APP1 is recorded regardless of the options specified.)

• JPEG_ENCODER_OPTION_OMIT_DHT
  DHT (Huffman table) is not recorded.
  If you are decoding JPEG data for which DHT data is not recorded, you must specify JPEG_DECODER_OPTION_ENABLE_DEFAULT_DHT usingJpegMpDecoder::SetOption. Furthermore, decoding may not be possible when using a JPEG decoder other than the JpegMpDecoder class.

The return value of JpegMpEncoder::GetOption is the bitwise OR of these constants.
