void CCamTile::CalcDiffValue ( const uchar * src )
 

Calculate absolute value of difference.

Assuming 'src' refers to a Delta panel, calculate the sum of the absolute difference.

void CCamTile::CalculateForward ( uchar * dst,
uchar * src )
 

Perform forward DCT calculation.

Parameters:
dst   Destination buffer; uses out_offsets
src   Source buffer; used in_offsets

void CCamTile::CalculateInverse ( uchar * dst,
uchar * src )
 

Perform inverse DCT calculation.

Parameters:
dst   Destination buffer; uses in_offsets
src   Source buffer; used out_offsets

Performs reverse DCT operation; note that the in/out_offsets are also swapped.

void CCamTile::ClearInTile ( uchar * dst )
 

Clear tile.

This sets the 64 pixels of the input tile to a value of 128.

void CCamTile::ClearOutTile ( uchar * dst )
 

Clear tile.

This sets the 64 pixels of the output tile to a value of 128.

int CCamTile::CompareTile ( const void * t1,
const void * t2 ) [static]
 

void CCamTile::CopyTile ( uchar * dst,
const uchar * src )
