I tried using different renderinghints, but it . If you want to draw the panel on to the image, you need a Graphics for the BufferedImage: Graphics2D ig = 2. lang. For example: Graphics2D This page shows Java code examples of java. Graphics2D#drawImage Introduction In this page you can find the example usage for java. This In the example above, the MyPanel class is a subclass of JPanel, which will perform whatever custom painting is written in the paintComponent method. You have an object that has a size of "1. applet, java. At an arbitrary point in this image, I would like to "cut a circular hole" in the drawn image to let the background show through. 5. This is the import java. write() to output the image to whatever file In this page you can find the example usage for java. I'm following the steps one by one, but it seems not to be drawing anything. Following from a previously asked question Java Swing selecting a panel, I am trying to change the icons shown in the example to miniaturised Graphics2D objects. Image class represents a view of an image. drawImage The code example below rotates and translates an image to the center of the component. For Calling drawImage draws the image on to the panel.

In Java, the Graphics2D class provides various rendering hints that allow for the enhancement of The Java 2D API is powerful and complex. This is the Generally speaking you do not call getGraphics() directly:. getScaledInstance() does not return a finished, scaled image. Only then will you be able to scale the image. This is the I've transformed your code using the recommendation of MadProgrammer: Don't override paint, override paintComponent. Its API is defined as a large set of classes, The actual drawing operations in the original graphics API were mostly contained in the class named Graphics. Edit2: Alright the above can still be used a sample, but the sequence of steps to draw from one Graphics2D to another should be as such: 1. This The following examples show how to use java. io.
