Function Documentation

gridToESRIRaster() [1/2]

template<class T >

QString gridToESRIRaster

(

const Grid< T > &

grid

)

gridToESRIRaster() [2/2]

template<class T >

QString gridToESRIRaster	(	const Grid< T > &	grid,
		QString(*)(const T &value)	valueFunction
	)

gridToImage()

QImage gridToImage	(	const FloatGrid &	grid,
		bool	black_white = false,
		double	min_value = 0.,
		double	max_value = 1.,
		bool	reverse = false
	)

creates and return a QImage from Grid-Data.

Parameters

black_white	true: max_value = white, min_value = black, false: color-mode: uses a HSV-color model from blue (min_value) to red (max_value), default: color mode (false)
min_value,max_value	min/max bounds for color calcuations. values outside bounds are limited to these values. defaults: min=0, max=1
reverse	if true, color ramps are inversed (to: min_value = white (black and white mode) or red (color mode). default = false.

Returns

a QImage with the Grids size of pixels. Pixel coordinates relate to the index values of the grid.

gridToString() [1/3]

QString gridToString	(	const FloatGrid &	grid,
		const QChar	sep = QChar(';'),
		const int	newline_after = -1
	)

dumps a FloatGrid to a String.

rows will be y-lines, columns x-values. (see grid.cpp)

gridToString() [2/3]

template<class T >

QString gridToString	(	const Grid< T > &	grid,
		const QChar	sep = QChar(';'),
		const int	newline_after = -1
	)

template version for non-float grids (see also version for FloatGrid)

Parameters

sep	string separator
newline_after	if <>-1 a newline is added after every 'newline_after' data values

gridToString() [3/3]

template<class T >

QString gridToString	(	const Grid< T > &	grid,
		QString(*)(const T &value)	valueFunction,
		const QChar	sep = QChar(';'),
		const int	newline_after = -1
	)

template version for non-float grids (see also version for FloatGrid)

Parameters

valueFunction	pointer to a function with the signature: QString func(const T&) : this should return a QString
sep	string separator
newline_after	if <>-1 a newline is added after every 'newline_after' data values

loadGridFromImage()

bool loadGridFromImage	(	const QString &	fileName,
		FloatGrid &	rGrid
	)

load into 'rGrid' the content of the image pointed at by 'fileName'.

Pixels are converted to grey-scale and then transformend to a value ranging from 0..1 (black..white).

modelToWorld()

void modelToWorld	(	const Vector3D &	From,
		Vector3D &	To
	)
