> Dear TransformJ users,
>
> TransformJ 4.0.0 is now available (
>
http://www.imagescience.org/meijering/software/transformj/) for ImageJ
> users and will soon also appear in the Fiji distribution.
>
> It is a long-awaited major update. So long, in fact, that in the meantime
> many of you probably got used to the shortcomings of the package and found
> ways to work around them. Needless to say these work-arounds will no longer
> work with the new version, so you may need to update your code/macros a bit.
>
> Apart from some cosmetic changes the most important fundamental change is
> that the Affine and Rotate plugins are now able to properly work with image
> stacks having anisotropic voxels. This means you no longer need to first
> resample your data to isotropic voxels (if this was part of your pipeline
> you will need to remove that step). The plugins offer the possibility to
> either sample the transformed image on the same grid (same anisotropy) as
> the input image (this is the default mode) or to resample the stack
> isotropically while transforming (an option to be selected by the user).
>
> Even though this means TransformJ now finally works the way it should have
> from the beginning, perhaps some of you would like to keep the old behavior
> of the plugins. This is possible. The only thing you need to do then is
> temporarily set the voxel width/height/depth to 1.0 (which is what
> TransformJ has been assuming all along previously), then perform the
> transformation, and afterwards put these properties back to their old
> values.
>
> For consistency with the Affine plugin (the most generic plugin of the
> package), two other changes were introduced. First, the Scale plugin by
> default no longer rescales the voxel properties in order to retain the
> physical image dimensions, but this is now an option (to be selected by the
> user). Second, the Translate plugin now assumes the translation distances
> to be in physical units (determined by the voxel properties), but an option
> has been added (to be selected by the user) to take these distances as
> voxel units.

> Have fun transforming your data!
