[udig-devel] [solved] raster's data recovery

[ragga doll]

Thanks, I have done ! Also uDig didn't want to render my raster because he have not got enough memory. Now, with this code and -Xmx250m directive, it's work fine.

GridCoverageFactory fact = new GridCoverageFactory(); 
Map map = (Map) ApplicationGIS.getActiveMap() ;
Layer l = (Layer) map.getMapLayers().get(0) ;
int tabValue[] = null ;
File file = new File(l.getID().getFile());
BufferedImage buffer = ImageIO.read(file);
Envelope envelope = l.getBounds(null, l.getCRS()) ;    
GridCoverage2D grid = fact.create("name", buffer, envelope) ;
Point2D.Double pixel = new Point2D.Double(-60.740 , -7.109);
tabValue = grid.evaluate(pixel, tabValue) ;
String msg = "begin";
for(int i = 0 ; i < tabValue.length ; i++)
    msg += "\n*" + tabValue[i] ;
System.out.println(msg + "\nend");
