- public class FITSImageDataOrigin
- extends ImageDataOrigin
an ImageDataOrigin with constructors set for the FITS convention.
FITS images place the data origin at the bottom left corner and
increasing to upward and to the right. The world coordinate associated
with the pixel is considered to be at the pixel's center.
Given that the internal data is public, there is nothing stopping the
user from altering the specification to a non-FITS convention.
-
FITSImageDataOrigin()
- create a FITSImageDataOrigin object with default values (height = 0).
-
FITSImageDataOrigin(int)
- create a FITSImageDataOrigin object with xsize = ysize = 1.
-
FITSImageDataOrigin(int, int, double, double)
- create a fully specified FITSImageDataOrigin object.
FITSImageDataOrigin
public FITSImageDataOrigin(int width,
int height,
double xsize,
double ysize)
- create a fully specified FITSImageDataOrigin object. Positive values
for xsize and ysize indicate that the axes increase to the right and
upward, respectively.
FITSImageDataOrigin
public FITSImageDataOrigin(int height)
- create a FITSImageDataOrigin object with xsize = ysize = 1. Note
that the width is not needed to use the data conversion methods.
FITSImageDataOrigin
public FITSImageDataOrigin()
- create a FITSImageDataOrigin object with default values (height = 0).
Note that height will need to be set in order to use getDataPixel()
and getDisplayPixel();
