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.

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)
