Inverting an image

[Jonathan Perel]

Here's a ScriptMaster module to color invert an image from a container field. The containerField input should be a text field with the name of the container field. You might need to increase your java memory size if you try to use this with a large image (http://docs.360works.com/index.php/Heapspace_Out_of_Memory_Error)

//Invert Image (containerField)
import javax.imageio.ImageIO;
import java.awt.image.BufferedImage;
import java.awt.image.RescaleOp;

InputStream input;

try{
 input = fmpro.getContainerStream(containerField);
}
catch(e){
 throw new RuntimeException( e );
 return false;
}

BufferedImage img = ImageIO.read(input);
RescaleOp op = new RescaleOp(-1.0f, 255f, null);
BufferedImage negative = op.filter(img, null);

return negative;

This code inverts an image in a container field within FileMaker. No need to export it, invert it, and re-import it.

So that means in the image inverting process, the resolution will not be reduced right? cuz some method will decode image, invert it and re-encode it.
