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.

Save an Image into a TGA file.

The TGA file is always 24-bits and uncompressed.
