int  ofhandle,
RVCRASTINFO *  RastInfo,
MIUNICODE *  Query,
DOUBLE  Direction,
int  AlongLineMethod,
int  AcrossLineMethod,
UINT32  flags
) 
 

Surface fit line vector data using Bidirectional method.

NOTE: This algrorithm is designed for geophysical line survey data. This algorithm makes sense for a vector object that contains a set of near parallel 3D lines. Do not use this algorithm unless you know why you are doing that!

How it works: 1. Algorithm estimates a dominant direction of the lines in the input vector object or uses a user supplied direction (set SURFACEFIT_UseDirection flag). 2. The output raster will be oriented in such way that input vector lines will run approx. vertically. 3. Algortihm does surface fitting along lines using AlongLineMethod. All pixels that are covered by input lines will have an output value assigned after this step is complete. 4. Algorithm does surface fitting accross input lines (along output raster lines) using AcrossLineMethod.

AlongLineMethod:

  • INTERPOLATE_SplineLinear - linear interpolation
  • INTERPOLATE_SplineCubic - uses cubic BSpline
  • INTERPOLATE_SplineQuad - uses quadratic BSpline
  • INTERPOLATE_SplineBezier - uses Bezier spline
AcrossLineMethod:
  • INTERPOLATE_SplineLinear - linear interpolation
  • INTERPOLATE_SplineCubic - uses cubic BSpline
  • INTERPOLATE_SplineQuad - uses quadratic BSpline
  • INTERPOLATE_SplineBezier - uses Bezier spline
Valid flags:
  • SURFACEFIT_AutoRescale - automatically rescale data to fit into output raster data type.
  • SURFACEFIT_UseDirection - use user supplied direction
Parameters:
vfhandle  Input vector file handle, returned by MfOpenFile()
inode  Input vector inode
ofhandle  Output file handle, returned by MfOpenFile()
RastInfo  Output raster header, fill out .name,.desc,.numbits,.datatype,.numlins,.numcols NOTE: Actual number if lines and columns in the output will be different and depends on data orientation
Query  NULL or standard TNTmips query string for selecting vector lines, use NULL to select all lines
Direction  If SURFACEFIT_UseDirection flag is set, this value is used as a primary direction of the surface fitting (radians)
AlongLineMethod  Surface fitting method to use along the lines
AcrossLineMethod  Surface fitting method to use across the lines

Copy an object and possibly subobjects, filter.

Flags:

  • COPYRVC_SubObjects Copy subobjects under object
  • COPYRVC_RasterLinks Transfer raster links instead of copying the raster
  • COPYRVC_DBaseLinks Transfer dbase links instead of copying the dbase
  • COPYRVC_RVCLinks Copy RVC object links instead of the objects themselves
  • COPYRVC_ObjectLinks (COPYRVC_RasterLinks | COPYRVC_DBaseLinks)
  • COPYRVC_AllLinks (COPYRVC_ObjectLinks | COPYRVC_RVCLinks)
NOTE: This function will call MfUpdateFile() to update the file's contents.
Parameters:
sfhandle  File handle for source file
sinode  Inode number for source object to copy
dfhandle  File handle for destination file
dpinode  Parent inode of resulting object
destinode  Destination object inode returned (NULL if not needed)
filt  Filter function to designate what to copy (NULL if not needed)
filtdata  User data passed to the filter function (NULL if not needed)
flags  COPYRVC_... flags

Copy an object.

NOTE: This function will call MfUpdateFile() to update the file's contents.

Parameters:
sfhandle  File handle for source file
sinode  Inode number for source object to copy
dfhandle  File handle for destination file
dpinode  Parent inode of resulting object
destinode  Destination object inode returned (NULL if not needed)
flags  COPYRVC_... flags

MfFiltFuncProto  FiltFunc,

UINT32  flags
) 
 

Copy subobjects selected by a filter from one parent to another.

Only the first level of subobjects (objects immediately under source parent) will be filtered. See MfCopyObject for description of MfFiltFuncProto.

Parameters:
sfhandle  File handle for source file
spinode  Inode number for parent for subobjects to copy
dfhandle  File handle for destination file
dpinode  Parent inode of resulting object
FiltFunc  Pointer to filter function. Return !0 to copy object
FiltData  "Hook" data to pass to filter function
flags  COPYRVC_... flags
