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.
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.

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

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

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.

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.

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.
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 !!!
