Detailed Description

Creates 2D structure diagrams of molecular graphs in the PostScript (PS) [WPS] format.

PSMolecularGraphWriter uses Vis::StructureView2D for the creation of 2D structure diagrams. All control-parameters and properties provided for the customization of Vis::StructureView2D are also supported by PSMolecularGraphWriter.

Constructor & Destructor Documentation

◆ PSMolecularGraphWriter()

CDPL::Vis::PSMolecularGraphWriter::PSMolecularGraphWriter ( std::ostream & os )

Constructs a PSMolecularGraphWriter instance that will write the image data to the output stream os.

Parameters

os	The output stream to write to.

Note: To ensure the validity of the written data, it is recommended to open the output stream in binary mode.

Member Function Documentation

◆ write()

Base::DataWriter<Chem::MolecularGraph>& CDPL::Vis::PSMolecularGraphWriter::write ( const Chem::MolecularGraph & molgraph )

virtual

Creates and outputs the 2D structure diagram of the molecular graph molgraph.

Parameters

molgraph The molecular graph for which to output the 2D structure diagram.

Returns: A reference to itself.

Implements CDPL::Base::DataWriter< Chem::MolecularGraph >.

◆ operator const void *()

CDPL::Vis::PSMolecularGraphWriter::operator const void * ( ) const

virtual

Returns a pointer whose value indicates the error state of the writer.

The operator allows to write expressions like:

if (writer) { ...

if (writer.write(...)) { ...

Returns: A non-null pointer if the writer is in a good state, a null pointer otherwise.

Note: The returned pointer is not meant to be dereferenced, it is just a state indicator.

See also: operator!()

Implements CDPL::Base::DataWriter< Chem::MolecularGraph >.

◆ operator!()

bool CDPL::Vis::PSMolecularGraphWriter::operator! ( ) const

virtual

Tells whether the writer is in a bad state.

The operator allows to write expressions like:

if (!writer) { ...

if (!writer.write(...)) { ...

Returns: false if the writer is in a good state, and true otherwise.

See also: operator const void*()

Implements CDPL::Base::DataWriter< Chem::MolecularGraph >.
