Functions
int	JKQTPGetColorChannel (QRgb rgb, int ch)
	retrieve an R/G/B/Alpha (ch == 0/1/2/3) value from the `QRgb` value rgb
template<class T>
void	JKQTPImagePlot_array2RGBimage (const T *dbl_in, int width, int height, QImage &img, int channel, double minColor, double maxColor, JKQTPRGBMathImageRGBMode rgbMode=JKQTPRGBMathImageModeRGBMode, bool logScale=false, double logBase=10.0)
	convert a 2D image (as 1D array) into a QImage and puts the image values into one color channel (set by channel).The other color channels are not changed! So a repeated call to this function for the SAME QImage will result in a step-by-step buildup of an image.
template<class T>
QVector< double >	JKQTPImagePlot_arrayToDVector (const T *input, int N)
	returns a vector containing all elements of the given array as doubles
QVector< double >	JKQTPImagePlot_BarrayToDVector (const bool *input, int N)
	returns a vector containing all elements of the given boolean array as doubles (true=1, false=0)
template<class T>
double	JKQTPImagePlot_getImageMax (const T *dbl, int width, int height)
	fin the maximum pixel value in the given image dbl with width width and height height
template<class T>
double	JKQTPImagePlot_getImageMin (const T *dbl, int width, int height)
	fin the minimum pixel value in the given image dbl with width width and height height
void JKQTCOMMON_LIB_EXPORT	JKQTPModifyImage (QImage &img, JKQTPMathImageModifierMode modifierMode, const void *dataModifier, JKQTPMathImageDataType datatypeModifier, int Nx, int Ny, double internalModifierMin, double internalModifierMax)
	modify the given image img, using modifier image dataModifier (of type datatypeModifier and size Nx * Ny), using values in the range internalModifierMin ... internalModifierMax )
void	JKQTPSetColorChannel (QRgb &rgb, int ch, int val)
	set the R/G/B/Alpha (ch == 0/1/2/3) value in the `QRgb` value rgb to val (0..255!)
QString JKQTCOMMON_LIB_EXPORT	ModifierModeToString (const JKQTPMathImageModifierMode &mode)
	convert a string to a ModifierMode
JKQTPMathImageModifierMode JKQTCOMMON_LIB_EXPORT	StringToModifierMode (const QString &mode)
	convert a ModifierMode to a string

retrieve an R/G/B/Alpha (ch == 0/1/2/3) value from the QRgb value rgb

◆ JKQTPImagePlot_array2RGBimage()

template<class T>

void JKQTPImagePlot_array2RGBimage	(	const T *	dbl_in,
		int	width,
		int	height,
		QImage &	img,
		int	channel,
		double	minColor,
		double	maxColor,
		JKQTPRGBMathImageRGBMode	rgbMode = JKQTPRGBMathImageModeRGBMode,
		bool	logScale = false,
		double	logBase = 10.0 )

inline

convert a 2D image (as 1D array) into a QImage and puts the image values into one color channel (set by channel).The other color channels are not changed! So a repeated call to this function for the SAME QImage will result in a step-by-step buildup of an image.

Note: All calls (except channel>=3, i.e. alpha) set alpha to 255. Only the call with channel==3 (alpha) sets alpha to the desired value. Calls with channel==4 (saturation), channel==5 (value) leave alpha as it is.

◆ JKQTPImagePlot_arrayToDVector()

template<class T>

QVector< double > JKQTPImagePlot_arrayToDVector	(	const T *	input,
		int	N )

inline

returns a vector containing all elements of the given array as doubles

◆ JKQTPImagePlot_BarrayToDVector()

QVector< double > JKQTPImagePlot_BarrayToDVector	(	const bool *	input,
		int	N )

inline

returns a vector containing all elements of the given boolean array as doubles (true=1, false=0)

◆ JKQTPImagePlot_getImageMax()

template<class T>

double JKQTPImagePlot_getImageMax	(	const T *	dbl,
		int	width,
		int	height )

inline

fin the maximum pixel value in the given image dbl with width width and height height

◆ JKQTPImagePlot_getImageMin()

template<class T>

double JKQTPImagePlot_getImageMin	(	const T *	dbl,
		int	width,
		int	height )

inline

fin the minimum pixel value in the given image dbl with width width and height height

◆ JKQTPModifyImage()

void JKQTCOMMON_LIB_EXPORT JKQTPModifyImage	(	QImage &	img,
		JKQTPMathImageModifierMode	modifierMode,
		const void *	dataModifier,
		JKQTPMathImageDataType	datatypeModifier,
		int	Nx,
		int	Ny,
		double	internalModifierMin,
		double	internalModifierMax )

modify the given image img, using modifier image dataModifier (of type datatypeModifier and size Nx * Ny), using values in the range internalModifierMin ... internalModifierMax )

◆ JKQTPSetColorChannel()

void JKQTPSetColorChannel	(	QRgb &	rgb,
		int	ch,
		int	val )

inline

set the R/G/B/Alpha (ch == 0/1/2/3) value in the QRgb value rgb to val (0..255!)

◆ ModifierModeToString()

QString JKQTCOMMON_LIB_EXPORT ModifierModeToString ( const JKQTPMathImageModifierMode & mode )

convert a string to a ModifierMode

◆ StringToModifierMode()

JKQTPMathImageModifierMode JKQTCOMMON_LIB_EXPORT StringToModifierMode ( const QString & mode )

convert a ModifierMode to a string
