Member Function Documentation

void KDcrawIface::KDcraw::cancel ( )

To cancel 'decodeHalfRAWImage' and 'decodeRAWImage' methods running in a separate thread.

Definition at line 73 of file kdcraw.cpp.

bool KDcrawIface::KDcraw::checkToCancelWaitingData ( )

protectedvirtual

Re-implement this method to control the cancelisation of loop witch wait data from RAW decoding process with your proper environment.

By default, this method check if m_cancel is true.

Definition at line 484 of file kdcraw.cpp.

bool KDcrawIface::KDcraw::decodeHalfRAWImage	(	const QString &	filePath,
		const RawDecodingSettings &	rawDecodingSettings,
		QByteArray &	imageData,
		int &	width,
		int &	height,
		int &	rgbmax
	)

Extract a small size of decode RAW data from 'filePath' picture file using 'rawDecodingSettings' settings.

This is a cancelable method which require a class instance to run because RAW pictures decoding can take a while.

This method return:

- A byte array container 'imageData' with picture data. Pixels order is RGB.
  Color depth can be 8 or 16. In 8 bits you can access to color component
  using (uchar*), in 16 bits using (ushort*).

- Size size of image in number of pixels ('width' and 'height').
- The max average of RGB components from decoded picture.
- 'false' is returned if decoding failed, else 'true'.

	)

Extract a full size of RAW data from 'filePath' picture file using 'rawDecodingSettings' settings.

This is a cancelable method which require a class instance to run because RAW pictures decoding can take a while.
