IIMGDEC_Params Struct Reference
[XDM IIMGDEC Image Decoder Interface]

#include <iimgdec.h>

Detailed Description

Defines the creation time parameters for all IIMGDEC instance objects.

Remarks:
The application should set the parameters to 0 to use the algorithm's default values.

This structure may be extended by individual codec implementations allowing customization with vendor specific parameters. The presence of vendor specific extensions will be detected by the value of the size parameter.

The size field must be correctly set by the caller.


Data Fields

XDAS_Int32 size
XDAS_Int32 maxHeight
XDAS_Int32 maxWidth
XDAS_Int32 maxScans
XDAS_Int32 dataEndianness
XDAS_Int32 forceChromaFormat

Field Documentation

XDAS_Int32 IIMGDEC_Params::size

Size of this structure in bytes. Because this structure can be extended, this field must be correctly set by the caller.

XDAS_Int32 IIMGDEC_Params::maxHeight

Maximum image height.

XDAS_Int32 IIMGDEC_Params::maxWidth

Maximum image width.

XDAS_Int32 IIMGDEC_Params::maxScans

Maximum number of scans.

XDAS_Int32 IIMGDEC_Params::dataEndianness

Endianness of output data.

See also:
XDM_DataFormat

XDAS_Int32 IIMGDEC_Params::forceChromaFormat

Chroma formats.

Remarks:
This enumeration data type should not be used for storage, but rather only for its constant values.

This enumeration defines a base set of values. Algorithms which require proprietary enumeration values may define them - much like extended fields in base structures. These extended enums should be between XDM_CUSTOMENUMBASE and 0x7FFF.
