FTARRAY (original) (raw)

Summary

The FTARRAY structure contains information about the complex 2D array that will hold the frequency components of the image.

Syntax

Members

uStructSize

FTARRAY structure size. Should be set to sizeof(FTARRAY).

uWidth

2D array width in pixels.

uHeight

2D array height in pixels.

acxData

The 2D data array. Note that, although only one element is declared in the array, the array contains uWidth * uHeight elements. The frequency component for the pixel (row, col) is acxData[row * uWidth + col].

Usage

• LBitmap::AllocFTArray
• LBitmap::DFT
• LBitmap::FFT
• LBitmap::FreeFTArray
• LBitmap::FrqFilter
• LBitmap::FrqFilterMask
• LBitmap::FTDisplay
