Detailed Description

Class for loading volume meta data (VolumeMetaData) as well as the raw volume data itself.

This uses a simple custom format for metadata, which is built on the Qt .ini file functionality provided by the QSettings class. Look at the example volumes to see the format, it is pretty straightforward. The loader supports reading gzipped volumes, through the gzip-library provided by Qt.

bool VolumeLoader::getMetadata	(	const QFile &	metadataFile,
		VolumeMetaData &	metadata
	)		const

Reads the metadata of a file.

Parameters

metadataFile	The file which contains the metadata.
metadata	The structure in which to store the return value

Returns

true if loading ok, false if error

QByteArray VolumeLoader::readVolume

(

const VolumeMetaData &

d

)

const

Reads the volume represented by this metadata.

Can handle gzipped data files.
