◆ allocate()

bool ossimNitfTileSource::allocate ( )

Allocates everything for current entry.

This is called on an open() or a entry change to an already open nitf file.

This does not allocate buffers and tiles to keep open and setCurrentEntry times to a minimum. Buffers are allocated on first grab of pixel data by allocatBuffers method.

Returns: True on success, false on error.
