Detailed Description

Bitmap provider returning always stored bitmap.

Stored bitmap can be changed only copying the bitmap from another bitmap provider using CopyFrom method. This object will be used to manage threading barrier for object supplier chain.

Member Function Documentation

◆ CopyFrom()

bool iipr::CBitmapProviderCacheComp::CopyFrom	(	const IChangeable &	object,
		CompatibilityMode	mode = CM_WITHOUT_REFS )

override

◆ GetBitmap()

const iimg::IBitmap * iipr::CBitmapProviderCacheComp::GetBitmap ( ) const

overridevirtual

Get access to produced bitmap object.

Returns: pointer to bitmap instance if this bitmap is accessible, or nullptr.

Implements iimg::IBitmapProvider.

◆ GetCalibration()

const i2d::ICalibration2d * iipr::CBitmapProviderCacheComp::GetCalibration ( ) const

overridevirtual

Get access to transformation object, which transforms a local logical coordinate system to global one.

Returns: Pointer to transformation if it is accessible, or nullptr.

Implements i2d::ICalibration2dProvider.

◆ ResetData()

bool iipr::CBitmapProviderCacheComp::ResetData ( CompatibilityMode mode = CM_WITHOUT_REFS )

overridevirtual

Reset data to its default state.

Default implementation in istd::IChangeable does nothing. You may check, if this functionality is supported over GetSupportedOperations().

Returns: true if the operation was successful, and false otherwise.

Reimplemented from istd::IChangeable.
