Method Detail

getYFlipTransform

public static java.awt.geom.AffineTransform getYFlipTransform(int height)

This returns an affine transform which will flip the vertical axis around. (NOTE: that this transform should be pre-concatenated with the existing one!) The returned transform will maintain the centerpoint of the window and flip the direction of the y-axis.

Parameters:

height - Description of Parameter

Returns:

The YFlipTransform value

getCCWRotateTransform

public static java.awt.geom.AffineTransform getCCWRotateTransform(int width,
                                                                  int height)

This returns an affine transform which will rotate the contents of the window by 90 degrees. (NOTE: that this transform should be pre-concatenated with the existing one!) The returned transform will rotate the contents of the window by 90 degrees while keeping the centerpoint the same. The x and y-scaling will be adjusted to keep the same area visible.

Parameters:

width - Description of Parameter

height - Description of Parameter

Returns:

The CCWRotateTransform value

getCWRotateTransform

public static java.awt.geom.AffineTransform getCWRotateTransform(int width,
                                                                 int height)

This returns an affine transform which will rotate the contents of the window by -90 degrees. (NOTE: that this transform should be pre-concatenated with the existing one!) The returned transform will rotate the contents of the window by -90 degrees while keeping the centerpoint the same. The x and y-scaling will be adjusted to keep the same area visible.

Parameters:

width - Description of Parameter

height - Description of Parameter

Returns:

The CWRotateTransform value
