Constructor & Destructor Documentation

GraphicDescriptor::GraphicDescriptor ( const GraphicDescriptor &  )

privatedelete

GraphicDescriptor::GraphicDescriptor

(

const INetURLObject &

rPath

)

Ctor to set a filename.

Detect() must be called to identify the file If the file has no unique header (Mtf's), the format is determined from the extension

Definition at line 31 of file graphicfilter2.cxx.

References CreateStream(), ImpConstruct(), NONE, and READ.

GraphicDescriptor::GraphicDescriptor	(	SvStream &	rInStream,
		const OUString *	pPath
	)

Ctor using a stream.

Detect() must be called to identify the file As some formats (Mtf's) do not have a unique header, it makes sense to supply the file name (incl. ext.), so that the format can be derived from the extension

Definition at line 39 of file graphicfilter2.cxx.

References aPathExt, INetURLObject::GetFileExtension(), and ImpConstruct().

GraphicDescriptor::~GraphicDescriptor

(

Definition at line 52 of file graphicfilter2.cxx.

References bOwnStream, and pFileStm.

Member Function Documentation

bool GraphicDescriptor::Detect

(

bool

bExtendedInfo = false

)

starts the detection

if bExtendedInfo == true the file header is used to derive as many properties as possible (size, color, etc.)
