Hi im not really sure how to explain this problem but i want to be able to grab pixels from a rectangle region on a screen at position x1,y1 and x2,y2 and copy those exact pixels onto a form... hard to explain I think


Here is a basic image example

It would look like that..where the red rectanagle region is copied into the form as the image shows.. does anyone know how I could do this?

You can get a picture of the entire desktop then only get the select area and save that image. Cant code atm so this is the only bit I can help.

Check out the class "Robot" in the "java.awt" package. Can do exactly what you want. Click.

But your screen is not transparent. What do you mean exactly? Do you want to add an alpha channel? Simply convert it.

Code

public static BufferedImage convert(final BufferedImage image, final int type) {
   final int width = image.getWidth();
   final int height = image.getHeight();
   final BufferedImage newImage = new BufferedImage(width, height, type);
   final Graphics2D g = newImage.createGraphics();

   g.drawImage(image, 0, 0, null);
   g.dispose();

   return newImage;
}

Then call it like this:

Code

final BufferedImage alphaImage = convert(screenImage, BufferedImage.TYPE_INT_ARGB);
