Rescaling 2-Dimensional Diagrams

RockPlot2D | Utilities | Rescale
or
RockWorks | Graphics | 2D Tools | Rescale

This program is used to rescale X,Y location coordinates in a graphic image using either of these methods:

• Using new origin coordinates and scaling multipliers. (Coordinates may be rescaled differently in the X and the Y directions.)
• Using new coordinates entered for one or more boundary edges.

• Input File (Graphics menu only): Click to the right to browse for the existing Rw2D file to be rescaled.

  • Type of Rescaling: Choose one of the following, and establish the necessary settings:
    • Origin & Scale: Use this method if you want to shift the coordinates of an existing map or diagram by assigning the plot file a new "origin" (southwest corner X,Y coordinates). This method also permits you to rescale the axes using a constant value, such as to divide the range of each axis by a factor of 100. You can set the origin and rescaling factors independently for each axis.
      • X-Origin: Type in the coordinate to become the new minimum X in the rescaled image. You can set this to 0 or to any arbitrary value, or you can type in the existing minimum X coordinate if known.
      • X-Scalar: All x-coordinates will be multiplied by this number. To increase the X-axis dimensions, use a number greater than 1 (e.g. 2.0 will double the dimension). To reduce the extent of the X-axis, use a number less than 1 (e.g. 0.5 will decrease the dimension by 2x).

      • Y-Origin: Type in the coordinate to become the new minimum Y in the rescaled image. You can set this to any real number value, or you can type in the existing minimum Y coordinate if known.
      • Y-Scalar: All y-coordinates will be divided by this number. See the information above for X-Scalar.
        
    • Min/Max Coordinates: Use this method to simply define new coordinates for one or more axes.
      • Minimum Easting: Type in the coordinates to represent the west or left side of the map or diagram.
      • Minimum Northing: Type in the coordinate to represent the south or bottom edge of the map or diagram.
      • Maximum Easting: Type in the coordinate to represent the east or right edge of the map or diagram.
      • Maximum Northing: Type in the coordinate to represent the north or top edge of the map or diagram.
      • 
        
• Output Options
  • Save Output File: Check this to assign a name for the map in advance, rather than displaying it as Untitled.
    • Automatic: Choose this option to have RockWorks assign the name automatically. It will use the name of the current program plus a numeric suffix, plus the ".Rw2D" file name extension.
    • Manual: Choose this option to type in a name of your own for this file.
  • Display Output: Check this option to have the resulting map displayed in RockPlot2D once it is created.

Step-by-Step Summary

1. If necessary, open the map or diagram to be rescaled (see Opening Plot Files) or click in the current RockPlot2D window containing that image and select the RockPlot2D Utilities | Rescale menu command.
   - OR -
   Select the RockWorks | Graphics | 2D Tools | Rescale menu option.
2. Enter the input and output file names and select the desired rescaling option, as described above.
3. Click the Process button to continue.

The program will shift and/or rescale the map as requested.

Tips

• If you need to know the existing coordinate range of any RockPlot2D image, select the View | Set Diagram Extents option.
