4.5.1 Data readers

The specific formats which are supported within Khoros 2.0:

A number of public domain utilities are available; for example the PBM Plus utilities could be used for importing data into a pnm format which can then be read by all Khoros operators.

4.5.2 Tools for importing data

Khoros has a different view on data import. In general, data access is performed through data services using one of the Khoros data models. Data services transparently supports a number of file formats. When a file is opened, data services checks the file to determine if it is one of the supported file formats. If it is, then the data contained in the file will be made available through the various segments in the data model. Applications which use data services can simply open up a file, and if the file is one of the supported formats, it will be able to access it. while most file formats can be automatically understood by Khoros operators, some file formats may need extra information to be imported correctly. The following routines are available for importing ASCII and raw data.

kimportasc: this routine allows you read an ASCII file into the Khoros 2.0 VIFF format, while specifying the size, data type, and index order of the ASCII data. Support for skipping points in the ASCII data is also provided. Simplified versions of this routine which read ASCII data into each of the polymorphic data segments are also available.
kimportraw: this routine allows you to specify details of the raw data format (such as what machine the data was created on) and import the data file into a Khoros 2.0 VIFF file.
kformats: this routine allows you to convert a file stored in any of the supported file formats to any of the other supported file formats.
