Function Documentation

unsigned short PN::ImageTool::blendPixel16 ( unsigned short  nSrc,
unsigned short  nDst,
int  nOpacity 
)
inline

Blends a single pixel in 16-bits RGB565 format.

Definition at line 73 of file ImageTool.h.

void PN::ImageTool::convertPixel16To24 ( unsigned short  nPixel,
unsigned char &  nRed,
unsigned char &  nGreen,
unsigned char &  nBlue 
)
inline

Converts a single pixel from 16-bits (565) RGB to 24-bits RGB.

Definition at line 64 of file ImageTool.h.

unsigned short PN::ImageTool::convertPixel24To16 ( int  nRed,
int  nGreen,
int  nBlue 
)
inline

Converts a single pixel from 24-bits RGB to 16-bits (565) RGB.

Definition at line 57 of file ImageTool.h.

void PN::ImageTool::convertPixelDataFrom16BitRGBTo24BitBGR ( unsigned char *  nDestData,
const unsigned short *  nPixelData,
unsigned int  nWidth,
unsigned int  nHeight 
)

Definition at line 49 of file ImageTool.cpp.

void PN::ImageTool::flipImageY ( unsigned char *  nDstBuffer,
unsigned const char *  nSrcBuffer,
int  nWidth,
int  nHeight,
int  nPixelSize 
)

Flips an image in Y-direction.

This method does simple scanline copying and can therefore flip any pixel buffer. nPixelSize is the number of bytes per pixel.

Definition at line 65 of file ImageTool.cpp.

bool PN::ImageTool::saveAsTGA ( Image nImage,
const char *  nFileName 
)

Save an Image into a TGA file.

The TGA file is always 24-bits and uncompressed.

Definition at line 96 of file ImageTool.cpp.
