| BifocalDistortion | | public class BifocalDistortion extends Distortion (Code) | |
Computes a bifocal distortion of space, magnifying a focus region of space
and uniformly demagnifying the rest of the space. The affect is akin to
passing a magnifying glass over the data.

| Constructor Summary | |
| public | BifocalDistortion()
Create a new BifocalDistortion with default range and magnification. | | public | BifocalDistortion(double range, double mag)
Create a new BifocalDistortion with the specified range and
magnification. | | public | BifocalDistortion(double xrange, double xmag, double yrange, double ymag)
Create a new BifocalDistortion with the specified range and
magnification along both axes.
NOTE:if the range value times the magnification
value is greater than 1, the resulting distortion can exceed the
display bounds.
Parameters:
xrange - the range around the focus that should be magnified alongthe x direction. |
| BifocalDistortion | | public BifocalDistortion()(Code) | | Create a new BifocalDistortion with default range and magnification.
|
| BifocalDistortion | | public BifocalDistortion(double range, double mag)(Code) | | Create a new BifocalDistortion with the specified range and
magnification. The same range and magnification is used for both
axes.
NOTE:if the range value times the magnification
value is greater than 1, the resulting distortion can exceed the
display bounds.
Parameters:
range - the range around the focus that should be magnified. Thisspecifies the size of the magnified focus region, and should be in therange of 0 to 1, 0 being no magnification range and 1 being the wholedisplay.
Parameters:
mag - how much magnification should be used in the focal area |
| BifocalDistortion | | public BifocalDistortion(double xrange, double xmag, double yrange, double ymag)(Code) | | Create a new BifocalDistortion with the specified range and
magnification along both axes.
NOTE:if the range value times the magnification
value is greater than 1, the resulting distortion can exceed the
display bounds.
Parameters:
xrange - the range around the focus that should be magnified alongthe x direction. This specifies the horizontal size of the magnified focus region, and should be a value between 0 and 1, 0 indicating nofocus region and 1 indicating the whole display.
Parameters:
xmag - how much magnification along the x direction should be usedin the focal area
Parameters:
yrange - the range around the focus that should be magnified alongthe y direction. This specifies the vertical size of the magnified focus region, and should be a value between 0 and 1, 0 indicating nofocus region and 1 indicating the whole display.
Parameters:
ymag - how much magnification along the y direction should be usedin the focal area |
