Graphics 2D Shape Cutter For BufferedImages

Jul 15, 2014

I'm going to make tiles for my RPG game, instead of drawing each shape of the tile, I will just draw the full tile in a spritesheet. I will create a sprite sheet of shapes that I want to clip somehow or use to cut the original full image into the shape I want. How can I, take a Buffered Image, cut it's shape and perhaps add something, giving me a Buffered Image of a cut tile with possibly added features that I can then draw with Graphics?

Write Out Multiple BufferedImages To Single TIFF File?

May 28, 2015

I need to write out multiple BufferedImages to a single tiff file. Each image represents a seismic time slice which can be several megabytes in size.  I have used the TIFFEncodeParam.setExtraImages method and saved all my BufferedImages to a vector but my since I create so many BIs I keep running out of memory. Is there a way to create a BI, write it out to a TIFF file, then discard the BI and create the next one?

Displacing A Shape Made Of Asterisks

May 5, 2014

I'm making a program that prints arrows of varying tail length, head width, and displacement.The shape algorithms are working properly, but the displacement isn't working. The first arrow has zero displacement, and the second one is supposed to be bigger and start the print at 10 spaces right and 5 spaces down from the default, but it's not working. I tried changing the displacement settings of the first arrow, and no changes happened, so I know that the positions aren't registering properly in general. How to pass the xAdj and yAdj (displacement) values? I think I have the empty space formula set up, but it's still not running.

Driver:
public class Driver
{
//default values
public static final int Arrow_Default_xAdj = 0;
public static final int Arrow_Default_yAdj = 0;
public static final int Arrow_Default_tail = 5;
public static final int Arrow_Default_width = 5;

[code]...

Printing Asterisks Shape In Java

Mar 17, 2014

I am supposed to Write a program that prints a shape similar to the following shape. Maximize use of loops and minimize use of print statements.

.....*
....**
...***
..****
...***
....**
.....*

(without the "...")(i couldn't get it to stay in shape)

This is what i got so far:

Java Code: package assignment7;

public class Exercise3
{
public static void main (String[] args)
{
for (int count =0; count < 4; count++)
{
for (int j=0; j < count+1; j++)
[Code] ....

Tthis compiles to:

*
**
***
****
**
*

How do i center it to create the shape?

Cutting Out Specific SHAPE From IMAGE

Apr 9, 2014

I'm making my 2D Java game, in my own style, in my own way. I'm trying to make it as code efficient as possible and compact, it usually is easier to change that way. I'm going to use BufferedImage subdivision on tilesets to take out tiles that I need, rather than creating multiple images with a tile each. Now, I've made multiple water tiles, for how they would be arranged differently.

So let's say you have a single water spot, it will be circular, you have two water spots, you have a tile-thick line with circular ends like two little water spots connected, this makes the game look more advanced, better, more realistic and good in many other ways. But, I found that an avarage amount of shapes needed is 25. I thought, how could I make this more efficient?

Could it be possible to use like shape cutting tools or something that would take out a specific shape of a single water tile to leave out all the different shapes, this is a good idea because I could use these tools for all kinds of different tiles in order to make specific features. By tools I mean simple black shapes which will remove the unwanted parts of the tile to form the wanted shape.

Tetris Game - Painting A Custom Shape

Dec 10, 2014

I am currently trying to make a Tetris game, so far I've got a class drawing that extends a JPanel as my canvas, a class Square that is 1 square(20 by 20) and a class LineShape that should draw 4 squares above each other. The class Frame way below is merely to set things up.

Currently i'm able to draw objects of my class Square, so I made a class LineShape that combines both and makes a 4Square long line.

My problem is when I try to draw an object of the class LineShape, it shows nothing, removes what is already painted(the square) and gives an error message:

Exception in thread "AWT-EventQueue-0" java.lang.NullPointerException
at LineShape.<init>(Screen.java:96)
at Drawing.paint(Screen.java:79)

I put my classes together so you can copy paste and run, make a new screen to start, to see the problem occur, go to the drawing class's paint method and uncomment these lines:

// LineShape shape = new LineShape(this);
// shape.paint(g);

Below are my classes:

import javax.swing.*;
import java.awt.*;
public class Screen {
private Frame frame;
private Frame inputFrame;
private JPanel panel;

The button0 is supposed to switch the color in window1, and button1 is supposed to switch the color in window0.

Calculate Distance From Starting Point Of Any Shape

Mar 13, 2015

I need to modify the drawShape method to calculate the distance from the starting point (the diameter) of any shape regardless of how many sides I give it, but I have absolutely no clue where to begin with this. The ultimate goal of the program is to calculate the value of pi using the shape that is drawn.

Here is the code:

public class PiTurtle extends Turtle
{
private double mySize;
private int mySides;
private double diameter = 0; 
final static double startX = 590.0;
final double startY;
public PiTurtle(int nSides)

JavaFX 2.0 :: Invalid Transform On Shape After Creation

Jan 21, 2015

I am working on a UI in JavaFX and create several instances of a custom control class. The control consists of a Pane which wraps several other containers, one of which contains a Circle shape.
 
At one point, I instance this control and access the Circle shape directly. I transform it's center coordinates (which are always {0.0, 0.0} ) to Scene coordinates.  The problem is, the transformation always yields coordinates that correspond to the upper left corner of the control's root pane.
 
In other words, it's as if the Circle is positioned at the upper left corner of the custom control (when, in fact, it's positioned near the lower right corner).
 
I have other instanced controls already in the scene, and they do not have this issue - converting the Circle's coordinates to scene coordinates works as it should.
 
It seems obvious that I'm accessing the Circle too soon - that perhaps the scene graph hasn't been fully traversed for the control and the Circle's position within the control's hierarchy hasn't been updated.  I've verified that my attempt to access the Circle's center coordinates occurs after the control's initialize() method is executed, so how to ensure the control's scene graph has been fully updated before I try to manipulate the control...

Making Patterns (Diamond Shape) Using Nested Loops

Mar 23, 2015

I have to make a pattern that is of a diamond shape such as this:

Java Code:
1
1 2 3
1 2 3 4 5
1 2 3
1
mh_sh_highlight_all('java');

I wrote this (for the variable name, this is just a small part of my program and I'm trying to get the pattern right so I didn't mind my variables at the moment):

Java Code:

public class NewFile{
public static void main(String []args){
int k = 0;
for (int i=1 ; i<=5 ; i++) {
{ for (int h=2 ; h >= i ; h--)

[Code] ....

My output is the following:

Java Code:
1
123
12345
1234567
123456789
mh_sh_highlight_all('java');

I realize I should divide the code into a lower and upper triangle using two loops. However, I don't know how to break the first part. I did find the "trend" but I don't see how to implement it.

Java 2D Drawing Application - Shape Should Be Drawn As Mouse Is Dragged

Nov 4, 2014

Java 2D Drawing Application. The application will contain the following elements:

a) an Undo button to undo the last shape drawn.

b) a Clear button to clear all shapes from the drawing.

c) a combo box for selecting the shape to draw, a line, oval, or rectangle.

d) a checkbox which specifies if the shape should be filled or unfilled.

e) a checkbox to specify whether to paint using a gradient.

f) two JButtons that each show a JColorChooser dialog to allow the user to choose the first and second color in the gradient.

g) a text field for entering the Stroke width.

h) a text field for entering the Stroke dash length.

I) a checkbox for specifying whether to draw a dashed or solid line.

j) a JPanel on which the shapes are drawn.

k) a status bar JLabel at the bottom of the frame that displays the current location of the mouse on the draw panel.

If the user selects to draw with a gradient, set the Paint on the shape to be a gradient of the two colors chosen by the user. If the user does not chosen to draw with a gradient, the Paint with a solid color of the 1st Color.

Note: When dragging the mouse to create a new shape, the shape should be drawn as the mouse is dragged.

Java Code:

import java.awt.BorderLayout;
import java.awt.Color;
import java.awt.Graphics;
import java.awt.GridLayout;
import java.awt.Point;
import java.awt.TextField;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.awt.event.MouseEvent;

How To Build Graphics

Jan 5, 2014

He said that if you need something that Swing can't provide, like a bar graph, you build it. Now, being used to just writing a method that will open up a JFrame, how you would actually build graphics on your own. How in the world would that work? How would one write their own methods to make a window or to build a graph?
