PDFPatternSpace

java.lang.Object
- java.awt.color.ColorSpace
- - com.inductiveautomation.rm.pdf.reader.PDFPatternSpace

All Implemented Interfaces:

java.io.Serializable
```
public class PDFPatternSpace
extends java.awt.color.ColorSpace
```
The Pattern colorspace is a special colorspace where shadings and tiling patterns can be declared. PDF treats this like other colorspaces, but it is not a full colorspace as far as awt is concerned. Awt colorspaces are expected to be able to convert colors between each other, but this doesn't make sense for patterns or shadings. The conversion methods just generate errors, so if the colorspace is ever used in a strange place (like an image) it will generate an exception, and we don't need to always be checking to see if a particular colorspace is appropriate for the given operation.
To draw in a pattern colorspace, you can ask the colorspace for a Paint object. Classes which implement the java.awt.Paint interface can be created for all the different shading types, as well as for tiling patterns.
