Convert a raster object to a TIN object.

Flags: TIN_ComputeStatistics Compute standard statistics for triangles and edges TIN_Optimize flags Do TIN optimization

NOTE: If there are no nodes in output TIN because of the data or optimization settings, the return code will be EUserCancel.

Parameters:
fhandle  Input file handle
inode  Raster inode
Filename  Output filename
TINinfo  Output object header
ZTolerance  Approximation accuracy
MaxNodes  Maximum number of nodes allowed in output TIN
deltaz  TIN optimization: elevation tolerance
shortedge  TIN optimization: min. edge lenght between 2 nodes that have elevation difference less than deltaz tolerance
longedge  TIN optimization: maximim allowed edge length
flags  flags
