`nn::jpeg::CTR` Namespace

Description

The CTR JPEG namespace.
(This namespace can also be written without the "::CTR" portion.)

Classes

`nn::jpeg::CTR::JpegMpDecoder`	This class performs JPEG decoding.
`nn::jpeg::CTR::JpegMpEncoder`	This class performs JPEG encoding.

Structures

`nn::jpeg::CTR::MpIndex`	Structure holding the MP Index IFD in a format easily processed by the library. The MP Index IFD is included in the data stored in MP format.
`nn::jpeg::CTR::MpEntry`	Structure holding an MP entry in a format easily processed by the library. MP entries are included in the data stored in MP format.
`nn::jpeg::CTR::Rational`	`RATIONAL` (unsigned rational number) data type, used for members of the MP Attribute IFD and GPS IFD.
`nn::jpeg::CTR::Srational`	`SRATIONAL` (signed rational number) data type, used for members of the MP Attribute IFD and GPS IFD.
`nn::jpeg::CTR::MpAttribute`	Structure holding the MP Attribute IFD in a format easily processed by the library. The MP Attribute IFD is included in the data stored in MP format.
`nn::jpeg::CTR::MpRegionsToBuildJpegData`	Structure holding the region information (pointer and byte count) for rebuilding JPEG data.

Enumerated Types

	`PixelSampling`	Enumerated type indicating the output format when encoding.
	`PixelFormat`	Enumerated type indicating the pixel format.
	`MpTypeFlag`	Flag(s) included in the MP type information.
	`MpTypeDataFormat`	Data format included in the MP type information.
	`MpTypeCode`	Type code included in the MP type information.

Constants

	`DEFAULT_THUMBNAIL_WIDTH`	Default thumbnail image width, in pixels.
	`DEFAULT_THUMBNAIL_HEIGHT`	Default thumbnail image height, in pixels.
	`DATE_TIME_SIZE`	Number of bytes in the buffer that stores date and time information. This constant is a string with the format "`YYYY:MM:DD HH:MM:DD`" terminated with `0x00`, for a total of 20 characters.
	`IMAGE_UID_SIZE`	The size in bytes of a JPEG unique image ID. This is the number of bytes in one element of the MP format's individual unique image ID list.
	`MP_ENTRY_SIZE`	The number of bytes in one element of an MP-format MP entry. This is not the number of bytes in the `MpEntry` structure.
	`MIN_DECODER_SHRINK_LEVEL`	Minimum value that can be specified for the shrink level when shrink decoding.
	`MAX_DECODER_SHRINK_LEVEL`	Maximum value that can be specified for the shrink level when shrink decoding.
	`TWL_PHOTO_MAKER_NOTE_SIZE`	The number of bytes in a MakerNote for the Nintendo DSi Camera application.
	`MAX_DECODER_OUTPUT_BUFFER_WIDTH`	Maximum value (number of pixels) that can be specified for the output image buffer width when decoding.
	`MAX_ENCODER_INPUT_BUFFER_WIDTH`	Maximum value (number of pixels) that can be specified for the input image buffer width when encoding.
	`DEFAULT_THUMBNAIL_PIXEL_SAMPLING`	Default thumbnail output format.
