Detailed Description

A bitmap that owns its data.

Constructor & Destructor Documentation

◆ Bitmap() [1/5]

CartoTypeCore::Bitmap::Bitmap	(	BitmapType	aType,
		int32_t	aWidth,
		int32_t	aHeight,
		int32_t	aRowBytes = `0`,
		std::shared_ptr< CartoTypeCore::Palette >	aPalette = `nullptr`
	)

Creates a bitmap that owns its data. If aRowBytes is less than the minimum possible set the number of bytes per row to the minimum possible.

◆ Bitmap() [2/5]

CartoTypeCore::Bitmap::Bitmap ( InputStream & aInputStream )

explicit

Creates a bitmap from a stream, starting at the current position. Supported source bitmap types: PNG and JPEG.

◆ Bitmap() [3/5]

CartoTypeCore::Bitmap::Bitmap ( const Bitmap & aOther )

Creates a Bitmap by copying a Bitmap.

◆ Bitmap() [4/5]

CartoTypeCore::Bitmap::Bitmap ( Bitmap && aOther )

noexcept

Creates a Bitmap by moving data from another Bitmap.

◆ Bitmap() [5/5]

CartoTypeCore::Bitmap::Bitmap ( const BitmapView & aOther )

Creates a Bitmap by copying a BitmapView.

Member Function Documentation

◆ DetachData()

std::vector< uint8_t > CartoTypeCore::Bitmap::DetachData ( )

inline

Detaches the data, transferring ownership to the caller.

◆ operator=() [1/2]

Bitmap & CartoTypeCore::Bitmap::operator= ( Bitmap && aOther )

The move assignment operator.

◆ operator=() [2/2]

Bitmap & CartoTypeCore::Bitmap::operator= ( const BitmapView & aOther )

The assignment operator.

◆ Read()

Bitmap CartoTypeCore::Bitmap::Read	(	Result &	aError,
		InputStream &	aInput
	)

static

Reads a bitmap that was written by BitmapView::Write
