What's New in IDL 6.4: New Features in IDL 6.4 |
|
The following enhancements have been made to IDL's file-access capabilities in the IDL 6.4 release:
IDL now supports transparency for GIF files through new keywords to both READ_GIF and WRITE_GIF. For more information, see IDL Routine Enhancements.
IDL now supports local colormaps for GIF files that contain multiple images.
The Open Geospatial Consortium (OGC) is an open-standards organization devoted to developing standards that govern web-based delivery of geospatial data including geographical information systems (GIS) data combined with location, elevation or other types of structure data. This release of IDL features two new network objects, IDLnetOGCWMS and IDLnetOGCWCS, that let you access Web Map Service servers and Web Coverage Service servers respectively. For more information, see New IDL Object Classes.
The Init, Load, and Save methods to the IDLffXMLDOMDocument object now support reading and writing XML data from and to IDL string variables, avoiding the need for file input/output.
Similarly, the ParseFile method to the IDLffXMLSAX object allows XML data to be read from a string variable or a remote URL.
For more information, see IDL Object Method Enhancements.
