Corrupt images using Export to Image Wizard
-------------------------------------------

                 Key: UDIG-1443
                 URL: http://jira.codehaus.org/browse/UDIG-1443
             Project: uDIG
          Issue Type: Bug
          Components: image
    Affects Versions: UDIG 1.2.M0
            Reporter: Jody Garnett
            Assignee: Jesse Eichar


The Export Map to Image wizard got a couple of fixes for the uDig 1.1.0 stream; when I went to update the code on trunk I found that structure of the code was different - rather than a single ImageExportPage.write(BufferedIMage,File) method that does everything ...
there are a bunch of Helper Classes.

I have ported the solution (namely skipping over ImageWriters that are not "standard") to the WorldImageExportFormat utility class.
{code}
//ImageIO.write(image, getName(), destination);
    	ImageOutputStream stream = null;
        try {
            destination.delete();
            stream = ImageIO.createImageOutputStream(destination);
        } catch (IOException e) {
            throw new IIOException("Can't create output stream!", e);
        }
    	try {
            ImageWriter writer = null;
            ImageTypeSpecifier type = ImageTypeSpecifier.createFromRenderedImage(image);
            Iterator<ImageWriter> iter = ImageIO.getImageWriters(type, formatName);
            while (iter.hasNext()) {
                writer = (ImageWriter) iter.next();
                String description = writer.getOriginatingProvider().getDescription(null);
                if( !description.contains("Standard") ){
                    break;
                }
            }
            if (writer == null) {
                throw new IOException("Could not find writer for this image in " + formatName);
            }
            writer.setOutput(stream);
            try {
                writer.write(image);
            } finally {
                writer.dispose();
                stream.flush();
            }
        } finally {
            stream.close();
        }
{code}
