java - What is the correct way to convert a Shape to a Rectangle2D.Double? -

-

I need to change a rectangle2D.Double (rotate). However, I do not need to attract the shape, I need to keep the changing rectangle in the form of an object so that I can use the .intersects () and other methods. This is the current way I am changing it 

  Personal Rectangle 2D Double Transform (Rectangle2D.Double rect) {// change a new AffineTransform transform = new AffineTransform (); // Apply conversion changes. Rotate (Math.Tudian (Theta), rect.x + rect.width / 2, rect.y + rect.height / 2); // Find the resulting size s = transform.createTransformedShape (hitbox); // Final rectangular rectangle return //? }

Now, someone can think that the following will work 

  Rectangle2D.Double newRect = new Rectangle2D.Double (); NewRect.setFrame (transform.createTransformedShape (Rect) .getBounds2D ());

However, when it is drawn, it does not seem that it can rotate in any way, rather in large quantities (140x larger).

is: How can I get it size , the way in which it is dragged, correctly changes to a correct form, a rectangle2D.Double ?

If this is not possible then what is a good option which is still .intersects () and similar methods?

rectangle 2D is axis-axis that can not be turned on instead Try using a Path2D is a good creator what you really want: 

  Personal Path 2D Double Transform (Rectangle 2D Double Rect) {AffineTransform transform = new AffineTransform (); Double Angle = Math Triadian (theta); Transform.rotate (angle, rect.x + rect.width / 2, rect.y + rect.height / 2); Return the new path 2D. Double (Rect, Transform); }

Also keep in mind that your toRadians (toRadians (theta)) is very suspicious and makes your angle too small.

java - Gradle dependencies: compile project by relative path -

Is it possible to specify a dependency on another gradeal project in the granular (in android studios) outside the current project limits? For example, with a relative path like this: dependence {collection project ('../../ stdlib / dagger'}} MyApp (path / user / foo / workspace / mypad) The app (Path / User / Foo / Workspace / MyPass / App) And I have an Android Library Project with 3 subdomules: stdlib (path is / user / foo / Utilities (Path / User / Foo / Workspace / Stadlib / Utilis) http (Path / User / Foo / Workspace / Stadlib / HT) / Li> What I have to do is compile the Dagger, Util, http module in the MyApp project. The Stidelib Library module under heavy development And MyApp will grow in the form of Growth, so I do not want to push them into a Mewen repository. I am a little change. is likely to add another Gredle projects in some way? I will push the study library into the Maven repository after the source is in search of a temp...
