IGFreqIPCtl Control
| ImageGear Professional v18.2 > API Reference Guide > FreqIP Component API Reference > FreqIP Component Objects > IGFreqIPCtl Control |
The Frequency Domain Image Processing component. The instance of IGFreqIPCtl should be either added to the form during design time, or created dynamically during run time. This object has no visible representation on screen and provides access to frequency domain functionalities.
IIGFreqIPCtl extends IIGFreqIP
