RendererUtilities (Geotools modules 31-SNAPSHOT API)

- RendererUtilities

```
public final class RendererUtilities
extends Object
```
This is a reduced copy of RenderUtilities found in the render module, to avoid adding a dependency on it while using only a few methods

Method Summary

All Methods Static Methods Concrete Methods
Modifier and Type	Method	Description
`static Envelope`	`createMapEnvelope(Rectangle paintArea, AffineTransform worldToScreen)`	Creates the map's bounding box in real world coordinates.

- Method Detail
  - worldToScreenTransform
```
public static AffineTransform worldToScreenTransform(ReferencedEnvelope mapExtent,
                                                     Rectangle paintArea)
```
    Sets up the affine transform
    NOTE It is worth to note that here we do not take into account the half a pixel translation stated by ogc for coverages bounds. One reason is that WMS 1.1.1 does not follow it!!!
    
    Parameters:
    
    mapExtent - the map extent
    
    paintArea - the size of the rendering output area
    
    Returns:
    
    a transform that maps from real world coordinates to the screen
  - createMapEnvelope
```
public static Envelope createMapEnvelope(Rectangle paintArea,
                                         AffineTransform worldToScreen)
                                  throws NoninvertibleTransformException
```
    Creates the map's bounding box in real world coordinates.
    
    Parameters:
    
    worldToScreen - a transform which converts World coordinates to screen pixel coordinates. No assumptions are done on axis order as this is assumed to be pre-calculated. The affine transform may specify an rotation, in case the envelope will encompass the complete (rotated) world polygon.
    
    paintArea - the size of the rendering output area
    
    Returns:
    
    the envelope in world coordinates corresponding to the screen rectangle.
    
    Throws:
    
    NoninvertibleTransformException
