RMImageReader

- com.inductiveautomation.rm.graphics.RMImageReader

All Implemented Interfaces:

RMImageData.ImageReader
```
public class RMImageReader
extends java.lang.Object
implements RMImageData.ImageReader
```
Uses ImageIO or JAI to read an image, its basic info and its decoded bytes. The reader tries to provide basic info without loading the entire image file into memory. Decoded bytes are only needed by things like PDF and Flash writers.
