I am just trying to rotate a JPG file by 90 degrees. However my code outputs image ( BufferedImage ) that is completely black. Here's the way to reproduce: (Download 3.jpg here ) private static BufferedImage transform(BufferedImage originalImage) { BufferedImage newImage = null; AffineTransform tx = new AffineTransform(); tx.rotate(Math.PI / 2, originalImage.getWidth() / 2, originalImage.getHeight() / 2); AffineTransformOp op = new AffineTransformOp(tx, AffineTransformOp.TYPE_BICUBIC); newImage = op.filter(originalImage, newImage); return newImage; } public static void main(String[] args)

I have trouble drawing a triangle with the draw(Graphics g) method in Java. I can draw a rectangle like so: public void draw(Graphics g) { g.setColor(colorFill); g.fillRect(p.x, p.y, width, height); g.setColor(colorBorder); g.drawRect(p.x, p.y, width, height); drawHandles(g); Where p represents "the top left corner of the shapes". How would I draw the triangle in the same manner? Could someone give me an example for a standard triangle? davidbuzatto There is not a drawTriangle method neither in Graphics nor Graphics2D. You need to do it by yourself. You can draw three lines using the drawLine

I'm currently working on the menu system for my Java game, and I wonder how I can center the text from Graphics.drawString() , so that if I want to draw a text whose center point is at X: 50 and Y: 50 , and the text is 30 pixels wide and 10 pixels tall, the text will start at X: 35 and Y: 45 . Can I determine the width of the text before I draw it? Then it would be easy maths. EDIT: I also wonder if I can get the height of the text, so that I can center it vertically too. Any help is appreciated! Daniel Kvist I used the answer on this question . The code I used looks something like this: /** *

I would like to add a feature to my application which allows the user to draw a straight line by clicking the mouse at the start location and releasing it at the end location. The line should move as the mouse moves until it is finally released; similar to the way that a line can be drawn using the Microsoft Paint application. How can implement this so that the line is repainted as it moves without repainting other things that may already be drawn in that rectangular area? Try this...Draw a red line on the screen as the mouse is moved (dragged). public static void main(String args[]) throws

I'm working with graphcis2d in Java and am currently using this to draw text into a bufferedImage Font font1 = new Font("Arial", Font.PLAIN, 120); g2d.setFont(font1); FontMetrics fm1 = g2d.getFontMetrics(font1); g2d.drawString(s[1], width/2-fm1.stringWidth(s[1])/2, height/4-70); I want to draw this text with an different color outline. GlyphVector gv = font1.createGlyphVector(g2d.getFontRenderContext(), s[1]); Shape shape = gv.getOutline(); g2d.setStroke(new BasicStroke(4.0f)); g2d.translate(width/2-fm1.stringWidth(s[1])/2, height/4-70); g2d.draw(shape); The problem with using this method,
