[udig-devel] feedback on grid coverage renderer support on trunk

[Jody Garnett]

Thanks to both Simone and Jesse for help ...

It seems that a few wrinkles are left:
#1 grid coverage renderer will only work if another renderer has caused 
JAI to load jpeg support first ... if not the following error occurs:
> Caused by: java.lang.IllegalArgumentException: ImageRead: No 
> OperationDescriptor is registered in the current operation registry 
> under this name.
>     at javax.media.jai.JAI.createNS(JAI.java:1074)

 #2 geotiff has changed it's contract with applications:

I can confirm that JAI does work - In my world wind tile accessor I make 
direct use of JAI like this:
To repeat this error vanishes after something else smacks JAI once - 
something else looks like this (from world wind tile accessor):
> ImageReader jpeg = 
> ImageIO.getImageReadersByFormatName("jpeg").next();                       
>  
> jpeg.setInput( input, true );                        
> return jpeg.read(0,null);
Simone I have committed a refresh of the tile code onto geotools trunk 
for you to look at and or/review.
