initTransform

public AffineTransform initTransform(int width,
                                     int height,
                                     double x0,
                                     double x1,
                                     double y0,
                                     double y1)

Initializes an affine transform for Cartesian coordinates from a TIN to pixel coordinates for rendering an image.

Parameters:

width - the width of the output image

height - the height of the output image

x0 - the x coordinate of the left side of the data area

x1 - the x coordinate of the right side of the data area

y0 - the y coordinate of the lower side of the data area

y1 - the y coordinate of the upper side of the data area

Returns:

if successful, a valid instance.

drawTin

public static void drawTin(org.tinfour.common.IIncrementalTin tin,
                           int width,

                           File file)
                    throws IOException

Provides a convenience method for rendering a TIN and writing the results to an image file

Parameters:

tin - a valid TIN.

width - the width of the output image

height - the height of the output image

file - the file for output

Throws:

IOException - in the event of an unsuccessful write operation
