Description
Affine class lacks many useful methods such as multiply, premultiply and similar. JavaFX developer has to implement his own operations on Affine matrices or use 3rd party library while internally used Affine3D has all the necessary operations.

The API added by changeset 9d384fe5774f.

Passing to CCR for Lombard. This is an essential API for most of the complex graphical applications. Without it users are forced to awkwardly workaround lack of transform operations by converting all the transforms back an forth to some other libraries.

I would really like to have this in 2.2, but it is a lot of API that needs to be carefully designed and that will probably need an huge amount of optimization code for its performance to be reasonable. I'm sorry but we are not able to make this happen for this release.
17-05-2012
We are now past feature freeze for 2.2, and this was never on the list of 2.2 features, so as far as I am concerned the target release is correct.
16-05-2012
Is the fix version correct? Is this only targeted at lombard? I think this should be 2.2

Affine class should contain methods for altering the matrix in place (inverse(), concatenate(Transform), setTransform(Transform), ..). The methods that return a new instance (getInverseTransform(), getConcatenation(), ...) should be present on Transform class. Affine should also contain methods for setting it (and/or factory methods for creating it) to a specific simple transformation, that could be used similarly to the factory methods on Transform class, but returning the Affine class. Also convenient methods as concatenateWithRotation may be useful. We definitely should have Point3D transform(Point3D) on Transform class. Consider other possible arguments as bounds etc.

You could do this with Java3D, and I think they their API was interesting.

I recently experimented a bit with the graphic features of JavaFX (Shapes, Group-Nodes and Transforms). One thing I very quickly stumbled over is the missing support for any kind of mathematical operations on (Affine) transforms. You can neither get at the matrix elements of a Scale, Translate, etc. (because these Affine transforms are not even a sub-class of Affine) nor could you perform any operations on them like for example combining two transforms into one or applying the transform or its inverse to a point. Sometimes even the documentation is wrong (see for example Scale: The description of the matrix completely ignores the pivot element which is an integral part of this class.) I really wonder how you can write any sophisticated graphics program without support for such kind of operations. Is there any magic way around this, which I don't know or has just nobody ever tried to do that? Further comments can be found in the thread "JavaFX and (Affine)Transforms" on the openjfx-dev@openjdk.java.net mailing list.

Affine transform is also an important part of Geographic Information Systems (GIS). Some implementations make an extensive use of java.awt.geom.AffineTransform and can not yet switch to the JavaFX transform classes in their current form. Almost every methods in the Java2D AffineTransform class are valuable, with special emphasis on: * transform(double[], int, double[], int, int) * transform(float[], int, float[], int, int) * transform(float[], int, double[], int, int) * transform(double[], int, float[], int, int) * concatenate(AffineTransform) * preConcatenate(AffineTransform) * getMatrix(double[]) * getScaleX(), getScaleY(), getShearX(), etc. * inverse(); Notes: Java2D AffineTransform is modifiable, while JavaFX transform classes seem to be immutable. Immutable transforms with 'concatenate' and similar methods returning new instances are fine. Transform methods working at arbitrary indexes of existing arrays are essential. GIS are typically transforming million of coordinates in their own geometry structures, not only for display purpose. We only need 'float[]' and 'double[]' array types (no need for 'int[]' for example). The 'double[]' type is essential - map projections in float precision have unacceptable errors. For example longitude/latitude angles in decimal degrees have a precision of approximatively one meter when using type 'float', while a centimeter accuracy is often required. The 'transform' methods mixing the arrays of 'float' and 'double' types in their signature are important. They are used in the following scenario, where to source of step 1 and and target of step 3 are arrays of type 'float[]', but the intermediate map projection must be performed in 'double' precision: 1. First, an affine transform for applying axis reordering, unit conversion, prime meridian rotation. The source array for this step may be 'float' or 'double', but the destination array must be 'double'. 2. Then the map projection is applied on the result of step 1 above. This projection must be performed on array of type 'double', otherwise errors are too high. 3. Finally, an affine transform is applied on the result of step 2 above, for applying scale factor, easting, northing, unit conversion and axis reordering. The source array for this step is always 'double', but the destination array may be 'double' or 'float'. In summary, the current Java2D AffineTransform API is excellent in my opinion. Having equivalent functionalities in JavaFX would be nice (hardware acceleration would be wonderful), eventually as immutable classes.
