public interface FormattedTransforming
extends CoordinateTransforming

Allows the retrieval of formatted description of the user space coordinates. This is useful for adding labels to drawings. In most cases, this will only work for two-dimensional user spaces with a more or less direct mapping of screen coordinates to user space coordinates.

Method Summary

Format	estimateX(double sx) From the step-size in user space, estimate a format.
Format	estimateY(double sy) From the step-size in user space, estimate a format.
List	formatUserCoordinates(Point2D norm) Formats all user-space coordinates and returns them as a list.
String	formatUserSpaceX(Point2D norm) Formats the x-coordinate in user space given a pixel in normalized screen coordinates.
String	formatUserSpaceY(Point2D norm) Formats the y-coordinate in user space given a pixel in normalized screen coordinates.
Format	getFormatUserX() For direct access this method retrieves the formatting instance used to fromat the user-space x coordinate.
Format	getFormatUserY() For direct access this method retrieves the formatting instance used to fromat the user-space x coordinate.
void	useEstimatedFormats(Rectangle2D view, int nx, int ny) Asks the transform to recalculate its x/y axis formatter for user space, giving the new view and the number of points in the axis.
