In This Topic

This function computes the forward Discrete Sine Transform (DST) of the input HIGCOMPLEXOBJ data.

Declaration:

	Copy Code
AT_ERRCOUNT ACCUAPI IG_FIP_DST_forward( HIGCOMPLEXOBJ hIGComplexObj, LPHIGCOMPLEXOBJ lphIGComplexObjOut );

Arguments:

Name	Type	Description
hIGComplexObj	HIGCOMPLEXOBJ	HIGCOMPLEXOBJ handle of data to be processed.
lphIGComplexObjOut	LPHIGCOMPLEXOBJ	HIGCOMPLEXOBJ handle of result data.

Return Value:

Returns the number of ImageGear errors that occurred during this function call.

Supported Raster Image Formats:

All pixel formats supported by HIGCOMPLEXOBJ object. See IG_FIP_co_obj_create.

Example:

	Copy Code
HIGCOMPLEXOBJ hIGComplexObj; /* HIGCOMPLEXOBJ handle of input image / HIGCOMPLEXOBJ hIGComplexObjOut; / HIGCOMPLEXOBJ handle of output image */ ... IG_FIP_DST_forward(hIGComplexObj, &hIGComplexObjOut); ...

Copy Code

HIGCOMPLEXOBJ hIGComplexObj;     /* HIGCOMPLEXOBJ handle of input image */
HIGCOMPLEXOBJ hIGComplexObjOut; /* HIGCOMPLEXOBJ handle of output image */
...
IG_FIP_DST_forward(hIGComplexObj, &hIGComplexObjOut);
