Member Function Documentation

convertDistanceToPixels()

double QgsProfileGenerationContext::convertDistanceToPixels	(	double	size,
		Qgis::RenderUnit	unit
	)		const

Converts a distance size from the specified units to pixels.

Definition at line 94 of file qgsabstractprofilegenerator.cpp.

distanceRange()

QgsDoubleRange QgsProfileGenerationContext::distanceRange ( ) const

inline

Returns the range of distances to include in the generation.

Distances outside this range may be excluded from the generation (if it results in faster profile generation).

See also

setDistanceRange()

Definition at line 330 of file qgsabstractprofilegenerator.h.

dpi()

double QgsProfileGenerationContext::dpi ( ) const

inline

Returns the DPI (dots per inch) for the profie, to be used in size conversions.

See also

setDpi()

Definition at line 371 of file qgsabstractprofilegenerator.h.

elevationRange()

QgsDoubleRange QgsProfileGenerationContext::elevationRange ( ) const

inline

Returns the range of elevations to include in the generation.

Elevations outside this range may be excluded from the generation (if it results in faster profile generation).

See also

setElevationRange()

Definition at line 348 of file qgsabstractprofilegenerator.h.

mapUnitsPerDistancePixel()

double QgsProfileGenerationContext::mapUnitsPerDistancePixel ( ) const

inline

Returns the number of map units per pixel in the distance dimension.

See also

setMapUnitsPerDistancePixel()

Definition at line 314 of file qgsabstractprofilegenerator.h.

maximumErrorMapUnits()

double QgsProfileGenerationContext::maximumErrorMapUnits ( ) const

inline

Returns the maximum allowed error in the generated result, in profile curve map units.

By default this is NaN, which indicates that the profile should be generated in the highest precision possible. Larger values will result in a faster profile to generate.

setMaximumErrorMapUnits()

Definition at line 297 of file qgsabstractprofilegenerator.h.

operator!=()

bool QgsProfileGenerationContext::operator!=

(

const QgsProfileGenerationContext &

other

)

const

Definition at line 141 of file qgsabstractprofilegenerator.cpp.

operator==()

bool QgsProfileGenerationContext::operator==

(

const QgsProfileGenerationContext &

other

)

const

Definition at line 132 of file qgsabstractprofilegenerator.cpp.

setDistanceRange()

void QgsProfileGenerationContext::setDistanceRange ( const QgsDoubleRange &  range )

inline

Sets the range of distances to include in the generation.

Distances outside this range may be excluded from the generation (if it results in faster profile generation).

See also

distanceRange()

Definition at line 339 of file qgsabstractprofilegenerator.h.

setDpi()

void QgsProfileGenerationContext::setDpi ( double  dpi )

inline

Sets the dpi (dots per inch) for the profie, to be used in size conversions.

See also

dpi()

Definition at line 364 of file qgsabstractprofilegenerator.h.

setElevationRange()

void QgsProfileGenerationContext::setElevationRange ( const QgsDoubleRange &  range )

inline

Sets the range of elevations to include in the generation.

Elevations outside this range may be excluded from the generation (if it results in faster profile generation).

See also

elevationRange()

Definition at line 357 of file qgsabstractprofilegenerator.h.

setMapUnitsPerDistancePixel()

void QgsProfileGenerationContext::setMapUnitsPerDistancePixel ( double  units )

inline

Sets the number of map units per pixel in the distance dimension.

See also

mapUnitsPerDistancePixel()

Definition at line 321 of file qgsabstractprofilegenerator.h.

setMaximumErrorMapUnits()

void QgsProfileGenerationContext::setMaximumErrorMapUnits ( double  error )

inline

Sets the maximum allowed error in the generated result, in profile curve map units.

By default this is NaN, which indicates that the profile should be generated in the highest precision possible. Larger values will result in a faster profile to generate.

maximumErrorMapUnits()
