|
|---|---|
AT_ERRCOUNT ACCUAPI IG_FIP_DCT_inverse_to_image(
HIGCOMPLEXOBJ hIGComplexObj,
LPHIGEAR lphIGear
);
|
|
Arguments:
| Name | Type | Description |
| hIGComplexObj | HIGCOMPLEXOBJ | HIGCOMPLEXOBJ handle of data to be processed. |
| lphIGear | LPHIGEAR | HIGEAR handle of result image. |
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.
 |
Pixel format of the output image is Grayscale – 8 or 16 bpp. |
Sample:
FreqIP
Example:
| Copy Code |
|
|---|---|
HIGCOMPLEXOBJ hIGComplexObj; /* HIGCOMPLEXOBJ handle of input data */ HIGEAR hIGear; /* HIGEAR handle of output image */ ... IG_FIP_DCT_inverse_to_image(hIGComplexObj, &hIGear); ... |
|
Remarks:
The difference between this function and IG_FIP_DCT_inverse() is that this function returns a HIGEAR as the result, using the default conversion type IG_FIPDATA_CONV_TYPE_REAL.
