Typedef Documentation

typedef struct IIMGENC_Obj IIMGENC_Obj

This must be the first field of all IIMGENC instance objects.

typedef struct IIMGENC_Obj* IIMGENC_Handle

Opaque handle to an IIMGENC objects.

typedef struct IIMGENC_Params IIMGENC_Params

Defines the creation time parameters for all IIMGENC 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 implementation allowing customization with vendor specific parameters. The size field must be correctly set by the caller.

typedef struct IIMGENC_DynamicParams IIMGENC_DynamicParams

This structure defines the codec parameters that can be modified after creation via control() calls. Remarks: It is not necessary that given implementation support all dynamic parameters to be configurable at run time. If a particular algorithm does not support run-time updates to a parameter that the application is attempting to change at runtime, it may indicate this as an error. The size field must be correctly set by the caller.

typedef struct IIMGENC_InArgs IIMGENC_InArgs

Defines the input arguments for all IIMGENC instance process function. Remarks: This structure may be extended by individual codec implementation allowing customization with vendor specific parameters. The size field must be correctly set by the caller.

typedef struct IIMGENC_Status IIMGENC_Status

Defines instance status parameters (read-only). Remarks: This structure may be extended by individual codec implementation allowing customization with vendor specific parameters. The size field must be correctly set by the caller.

typedef struct IIMGENC_OutArgs IIMGENC_OutArgs

Defines the run time output arguments for all IIMGENC instance objects. Remarks: This structure may be extended by individual codec implementations allowing customization with vendor specific parameters. The size field must be correctly set by the caller.

typedef IALG_Cmd IIMGENC_Cmd

Defines the control commands for the IIMGENC module. Remarks: This ID can be extended in IMOD interface for additional controls. See also: XDM_CmdId

typedef struct IIMGENC_Fxns IIMGENC_Fxns

Defines all of the operations on IIMGENC objects.
