Function Documentation

void CxImage::AddAveragingCont ( RGBQUAD const &  color,
float const   surf,
float &  rr,
float &  gg,
float &  bb,
float &  aa 
) [protected, inherited]

Helper function for GetAreaColorInterpolated. Adds 'surf' portion of image pixel with color 'color' to (rr,gg,bb,aa).

void CxImage::bihtoh ( BITMAPINFOHEADER *  bih  )  [protected, inherited]

void CxImage::Bitfield2RGB ( BYTE *  src,
DWORD  redmask,
DWORD  greenmask,
DWORD  bluemask,
BYTE  bpp 
) [protected, inherited]

turns a 16 or 32 bit bitfield image into a RGB image

BYTE CxImage::BlindAlphaGet ( const long  x,
const long  y 
) [protected, inherited]

Get alpha value without boundscheck (a bit faster). Pixel must be inside the image.

***bd*** 2.2004

RGBQUAD CxImage::BlindGetPixelColor ( const long  x,
const long  y,
bool  bGetAlpha = true 
) [protected, inherited]

This is (a bit) faster version of GetPixelColor. It tests bounds only in debug mode (_DEBUG defined).

It is an error to request out-of-borders pixel with this method. In DEBUG mode an exception will be thrown, and data will be violated in non-DEBUG mode.

BYTE CxImage::BlindGetPixelIndex ( const long  x,
const long  y 
) [protected, inherited]

void * CxImage::BlindGetPixelPointer ( const long  x,
const long  y 
) [protected, inherited]

Returns pointer to pixel. Currently implemented only for truecolor images.

Parameters:
x,y - coordinates
Returns:
pointer to first byte of pixel data

***bd*** 2.2004

BYTE CxImage::BlindSelectionGet ( const long  x,
const long  y 
) [protected, inherited]

Gets the Selection level for a single pixel "blind" version assumes that (x,y) is inside to the image.

bool CxImage::BlindSelectionIsInside ( long  x,
long  y 
) [protected, inherited]

Checks if the coordinates are inside the selection. "blind" version assumes that (x,y) is inside to the image.

void CxImage::BlindSetPixelColor ( long  x,
long  y,
RGBQUAD  c,
bool  bSetAlpha = false 
) [protected, inherited]

void CxImage::BlindSetPixelIndex ( long  x,
long  y,
BYTE  i 
) [protected, inherited]

void CxImage::blur_line ( float *  ctable,
float *  cmatrix,
int  cmatrix_length,
BYTE *  cur_col,
BYTE *  dest_col,
int  y,
long  bytes 
) [protected, inherited]

this function is written as if it is blurring a column at a time, even though it can operate on rows, too. There is no difference in the processing of the lines, at least to the blur_line function.

void CxImage::blur_text ( BYTE  threshold,
BYTE  decay,
BYTE  max_depth,
CxImage iSrc,
CxImage iDst,
BYTE  bytes 
) [protected, inherited]

Author:

int CxImage::CompareColors ( const void *  elem1,
const void *  elem2 
) [static, protected, inherited]

Returns:
lightness difference between elem1 and elem2

void CxImage::CopyInfo ( const CxImage src  )  [protected, inherited]

Copies the image attributes from an existing image.

bool CxImage::DFT ( int  dir,
long  m,
double *  x1,
double *  y1,
double *  x2,
double *  y2 
) [protected, inherited]

Direct fourier transform o(n)=n^2 Written by Paul Bourke, July 1998

bool CxImage::EncodeSafeCheck ( CxFile hFile  )  [protected, inherited]

bool CxImage::FFT ( int  dir,
int  m,
double *  x,
double *  y 
) [protected, inherited]

This computes an in-place complex-to-complex FFT x and y are the real and imaginary arrays of n=2^m points. o(n)=n*log2(n) dir = 1 gives forward transform dir = -1 gives reverse transform Written by Paul Bourke, July 1998 FFT algorithm by Cooley and Tukey, 1965

int CxImage::gen_convolve_matrix ( float  radius,
float **  cmatrix_p 
) [protected, inherited]

generates a 1-D convolution matrix to be used for each pass of a two-pass gaussian blur. Returns the length of the matrix.

Author:
[nipper]

float * CxImage::gen_lookup_table ( float *  cmatrix,
int  cmatrix_length 
) [protected, inherited]

generates a lookup table for every possible product of 0-255 and each value in the convolution matrix. The returned array is indexed first by matrix position, then by input multiplicand (?) value.

void CxImage::Ghost ( const CxImage from  )  [protected, inherited]

(this) points to the same pDib owned by (*from), the image remains in (*from) but (this) has the access to the pixels. Use carefully !!!

float CxImage::HueToRGB ( float  n1,
float  n2,
float  hue 
) [static, protected, inherited]

bool CxImage::IsPowerof2 ( long  x  )  [protected, inherited]

void CxImage::RGBtoBGR ( BYTE *  buffer,
int  length 
) [protected, inherited]

swaps the blue and red components (for RGB images)

Parameters:
buffer : pointer to the pixels
length : number of bytes to swap. lenght may not exceed the scan line.

void CxImage::SelectionSet ( const long  x,
const long  y,
const BYTE  level 
) [protected, inherited]

Sets the Selection level for a single pixel internal use only: doesn't set SelectionBox. Use SelectionAddPixel

void CxImage::Startup ( DWORD  imagetype = 0  )  [protected, inherited]

Initialize the internal structures
