Member Function Documentation

clone()

ImagePixelData::Ptr juce::SubsectionPixelData::clone ( )

overridevirtual

Creates a copy of this image.

Implements juce::ImagePixelData.

Definition at line 182 of file juce_Image.cpp.

createLowLevelContext()

std::unique_ptr< LowLevelGraphicsContext > juce::SubsectionPixelData::createLowLevelContext ( )

overridevirtual

Creates a context that will draw into this image.

Implements juce::ImagePixelData.

Definition at line 166 of file juce_Image.cpp.

createType()

std::unique_ptr< ImageType > juce::SubsectionPixelData::createType ( ) const

overridevirtual

Creates an instance of the type of this image.

Implements juce::ImagePixelData.

Definition at line 197 of file juce_Image.cpp.

getSharedCount()

int juce::SubsectionPixelData::getSharedCount ( ) const

overridevirtualnoexcept

Returns the number of Image objects which are currently referring to the same internal shared image data.

This is different to the reference count as an instance of ImagePixelData can internally depend on another ImagePixelData via it's member variables.

Reimplemented from juce::ImagePixelData.

Definition at line 200 of file juce_Image.cpp.

initialiseBitmapData()

void juce::SubsectionPixelData::initialiseBitmapData ( Image::BitmapData &  , int  x, int  y, Image::BitmapData::ReadWriteMode    )

overridevirtual

Initialises a BitmapData object.

Implements juce::ImagePixelData.

Definition at line 174 of file juce_Image.cpp.
