default

Constructor for QgsCubicRasterResampler.

Member Function Documentation

clone()

QgsCubicRasterResampler * QgsCubicRasterResampler::clone ( ) const

overridevirtual

Gets a deep copy of this object.

Needs to be reimplemented by subclasses. Ownership is transferred to the caller.

Implements QgsRasterResampler.

Definition at line 23 of file qgscubicrasterresampler.cpp.

resample()

Q_NOWARN_DEPRECATED_PUSH void QgsCubicRasterResampler::resample ( const QImage &  srcImage, QImage &  dstImage  )

overridevirtual

Resamples a source image to a destination image.

The size of the passed destination image should be respected during the resampling process.

Deprecated:

since QGIS 3.10.1, use the more efficient QgsRasterResamplerV2 interface instead.

Implements QgsRasterResampler.

Definition at line 34 of file qgscubicrasterresampler.cpp.

resampleV2()

QImage QgsCubicRasterResampler::resampleV2 ( const QImage &  source, const QSize &  size  )

overridevirtual

Resamples a source image to the specified size.

Returns the resampled image, or a null QImage if the resampling fails.

Implements QgsRasterResamplerV2.

Definition at line 28 of file qgscubicrasterresampler.cpp.

tileBufferPixels()

int QgsCubicRasterResampler::tileBufferPixels ( ) const

overridevirtual

Returns the optional tile buffer size in pixels.

This represents the size to buffer individual resampled tile requests prior to resampling, in order to avoid rendering artifacts at the edges of raster tile boundaries.

Since

QGIS 3.10.1

Reimplemented from QgsRasterResampler.

Definition at line 45 of file qgscubicrasterresampler.cpp.

type()

Q_NOWARN_DEPRECATED_POP QString QgsCubicRasterResampler::type ( ) const

overridevirtual

Gets a descriptive type identifier for this raster resampler.

Needs to be implemented by subclasses.

Implements QgsRasterResampler.

Definition at line 40 of file qgscubicrasterresampler.cpp.
