To try to code graphics without doing this is about as useful as groping about in the dark. But groping about in the dark is so much fun ;-) ;-) Oh wait, we're talking about programming here :( db

That black part is part of your image. The condition for using the code in my reply above was that the image has an alpha channel. Your image has no alpha channel . Use one of either TYPE_INT_ARGB, TYPE_4BYTE_ABGR, TYPE_INT_ARGB_PRE, TYPE_4BYTE_ABGR_PRE, or GraphicsConfiguration#createCompatibleImage(int width, int height, Transparency.BITMASK)

Cut polygon from image

I have just used wikipedia to see what the hell now "rhetorical" means and I can say only: no, no, no, it is not rhetorical, please answer my post! :) Let me try to make it more simple: I have 2 images (BufferedImage) and both images have colored content and black areas. I'd like to join those 2 images into 1 image (draw one over the other) and to make black areas disappear, because where first image has black area where the...

Then you need to go back and read the tutorial on graphics, post some code--a short working model showing your problem. When you make a GUI and use a JPanel to show your image, you override the paintComponent to show the image, it will not affect your layout.

Check out Area. Create an Area for you whole area and an Area for your cutout, and use Area. subtract(? check out the API)
You can then set this as the graphics clipping and voila

You should use one of the rotation
if text orientation should be from up to down of rotated page use the first approach
if (orientation == ORIENTATION_DOWN_UP) {
g2d.rotate( -Math.PI / 2, 0, 0);
g2d.translate( -w, 0);
}
else {
g2d.rotate(Math.PI / 2, 0, 0);
g2d.translate(0, -h);
}

Use a JPanel and layout manager and you'll need another JPanel too. To do this right, you need to use components for each result you want shown and it is possible by using the appropriate layout.
You can do all of this in just the JFrame using absolute layout, but I do not recommend it.

To begin with, you don't paint 'on' a Graphics2D object, you paint with a Graphice object on a painting surface which is usually some subclass of Component.
If you're using AffineTransform, read the API for createTransformedShape.

1. Do you claim to be running that uncompilable code?
2. Do custom painting in an extended JPanel or JCOmponent, not in a top level window.
3. Performing Custom Painting

I don't get the desired results.
Perhaps you'd like to tell us what results you do get? Also, why construct a FileInputStream when there is a form of createFont that accepts a File?
And please correct your indenting, it's very difficult to follow code with mismatching indents and outdents. And posting meaningless IDE-generated comments, and that too wrongly located, is yet another ...

Graphics Addressing Remapping Table? (GART) or Golden Valley Agricultural Research Trust (GART) or German American Research Trust (GART). Perhaps you could explain what it is that you want. If it's the remapping table, then please explain a bit about what you want to do with it, because as far as I can see, it's not going to have any bearing on Java programming.
