Titolo: VETTORIZZATORE AIUTO

Saluti,
ho un programma per vettorizzare le mappe catastali dal nome GTX RASTERCAD
5.0 il quale oltre a vettorizzare le mappe (trasformare un immagine in linee
per autocad) ha l'opzione di portare in scala l'oggetto vetorizzato tramite
il comando gWarp.
Il problema che ti pongo e come si fa ad eseguire tale operazione (premetto
che il programma è in inglese) perché non riesco a decifrare i passi
descritti nel manuale.
Se sai l'inglese o  usi un programma analogo al mio dai un occhiata al testo
allegato sotto a questo messaggio dove è descritto in inglese il comando
gWarp
Spero che tu abbia piacere ti darmi una mano
Abbreviation: GW
Availability: GTXRaster CAD, GTXRaster R2V, GTXRaster CAD PLUS
Function:
gWARP corrects distortion in a raster image by stretching the image data
between source and destination points.
Options:
The Image Warp dialog establishes warp source and destination point pairs.
These point pairs define the way the image is to be stretched.
Add Point Pairs creates one pair at a time.
Generate Grid creates a lower left corner, an upper right corner, and
intermediate grid points.
Instructions:
Warping requires the definition of source and destination point pairs.  When
CMDDIA is set to 1, the Image Warp dialog allows the creation of individual
point pairs or an entire array of them.  When CMDDIA is set to 0, a series
of prompts gathers the same information.
Add Point Pairs
The Add Point Pairs button lets you add individual pairs of source and
destination points.
Source point on the drawing (1):
1. Type or select a point on the image representing a known coordinate.
Warp point (#.###,#.###):
2. Type or select the real location to which the source point is to be
warped or displaced.
Source point on the drawing (2):
3. Enter another source point or press [RETURN] to go back to the Image Warp
dialog.
The specified points appear in the Coordinate List Table.
Generate Grid
The Generate Grid button lets you create a rectangular grid of destination p
oints and then for each point, enter the source points. This is backwards
from the prompts for Add Point Pairs, but it provides a convenient way of
generating a list of known real coordinates and then provide the location of
each of those features in the raster image.
Select base point of grid:
1. This point may be the lower left corner of the image, or one corner of a
grid of known coordinates.
Select opposite corner of grid:
2. Select the corner opposite the base point.  This defines the total area
the grid will occupy.
Select first corner for cell size:
3. Select one corner to define the cell size.  This might be the same point
as the base point.
Select opposite corner for cell size:
4. Select the other corner of the cell to define its overall size.  The grid
will fill up with cells whose size is defined by the first and opposite
corners.
For each grid point generated by steps 1-4, the following prompt will
appear:
New source point on the drawing (#.###,#.###):
5. A line will be rubber-banding from one of the grid points.  Select the
raster point nearby that is supposed to be representing this real point in
space.
When all the grid (destination) points have prompted for their respective
source points, the Image Warp dialog will re-appear showing the entire list
of point pairs in the Coordinate List Table.
Save List
The Save List button saves the list of point pairs in an ASCI text file.
The default filename is warp.txt.
Delete Point Pair
Deletes the selected point pair in the Coordinate List Table.
Modify Point Pair
Re-enters the selected point pair in the Coordinate List Table.
Clear All Points
Erases ALL point pairs in the Coordinate List Table.
Prompt Instructions
When CMDDIA = 0, the following prompts are issued instead of command
dialogs:
Enter number of warp points:
1. Enter the number of warp points for gWARP to create.
Source point on the drawing (1):
2. Select or enter the coordinates of the first source point.  This will be
the location in the raster image that will be stretched to a new
(destination) position.
Warp Point (#.###,#.###):
3. A rubber-banding line will stretch from the source point to the cursor.
Select or enter the coordinates of the destination point.  This will be the
location to which the source point is to be stretched.
Source point on the drawing (2):
4. Continue entering source and destination point pairs until all the warp
points are done.
Now warping image
The image is warped.
