IJ and macros/Java code

[Sebastian B=?UTF-8?Q?=C3=B6ckmann?=]

Hello,

I've the following problem:
If I use the code

IJ.run(imp, "Rotate... ", "angle=45 grid=3 interpolation=Bilinear enlarge");

... in my Java application, then the program does not show the rotated image and the program seems to be crashed somehow. So I tried to rebuild the code:

ip.setInterpolationMethod(ip.BILINEAR);
ip.rotate(45);

But how do I rebuild the "enlarge" parameter to show the image properly?

Best regards
Sebastian

Hello Sebastian,

try to use Rotator instead of ip.rotate().

You have to 'show' the image. Here is an example script, created using the command recorder, that rotates the blobs sample image 45 degrees:

  imp = IJ.openImage("http://imagej.nih.gov/ij/images/blobs.gif");
  IJ.run(imp, "Rotate... ", "angle=45 interpolation=Bilinear enlarge");
  imp.show();
