Detailed Description

Set options for reader/writer modules.

The class is used in a twofold way.

1. In combination with reader modules the class is used
   • to pass hints to the reading module, whether the input is binary and what byte ordering the binary data has
   • to retrieve information about the file contents after succesful reading.
2. In combination with write modules the class gives directions to the writer module, whether to
   • use binary mode or not and what byte order to use
   • store one of the standard properties.

The option are defined in Options::Flag as bit values and stored in an int value as a bitset.

Member Enumeration Documentation

Flag

enum OpenMesh::IO::Options::Flag

Definitions of Options for reading and writing.

The options can be or'ed.

Enumerator
Default	No options.
Binary	Set binary mode for r/w.
MSB	Assume big endian byte ordering.
LSB	Assume little endian byte ordering.
Swap	Swap byte order in binary mode.
VertexNormal	Has (r) / store (w) vertex normals.
VertexColor	Has (r) / store (w) vertex colors.
VertexTexCoord	Has (r) / store (w) texture coordinates.
EdgeColor	Has (r) / store (w) edge colors.
FaceNormal	Has (r) / store (w) face normals.
FaceColor	Has (r) / store (w) face colors.
FaceTexCoord	Has (r) / store (w) face texture coordinates.
ColorAlpha	Has (r) / store (w) alpha values for colors.
ColorFloat	Has (r) / store (w) float values for colors (currently only implemented for PLY and OFF files)
Custom	Has (r) custom properties (currently only implemented in PLY Reader ASCII version)
Status	Has (r) / store (w) status properties.
TexCoordST	Write texture coordinates as ST instead of UV.
