Drawing a String at an angle

Hi,
I have use the Graphics class to develope a map of streets etc and I wish to place the name of the streets running parallel to the streets themselves.
The drawString method allows me to specifiy the string and start co-ordinates but can anyone tell me how I can specify the strings baseline or the start and end co-ordinates of the string in order to display the string parallel to the street.
Thanks

Assuming your using Swing and not AWT...
1. Convert your graphics object into a graphics2D object;
Graphics2D g2 = (Graphics) g;
2. use translate(x, y) to recenter your world. In general, I like to return to the center when I'm done with operations at that point
3. useGraphics2D.rotate(...) to rotate your string drawing. Always remember that strings draw from the bottom left hand corner.

Draw a string with one character in a different color

This problem sounds trivially simple, but I don't have a clue on how to implement it.
What I'm basically trying to do, is use Graphics2D.drawString() to draw a string...but I want one letter to be in a different color. Guessing from the API this could be possible with an AttributedCharacterIterator, but I don't know how to set 'color' as one of the attributes.
Does anyone with knowledge of Java 2D havy any solution for this?

How to draw 2 Strings one after the other?

Hello,
I have this code, and I would like to know how can I draw the string "s2" right after the first string "s1" on this panel, so that it comes right behind it while they're moving?
Also, how can I make some of the strings drawn clickable (Like links) so that when I press on them some action is performed?
Thanks a lot.

      frame.setSize(600,600);
}

Use g.getFontMetrics().stringWidth(s1) to get width of the s1. Add the number to the x2.
To have it clickable create Rectangle(s) for the string bounds. When user clicks use x and y position and check if the rectangle contains the point.

Graphic2D.drawString() isn't drawing my strings. Help!!

Hello everybody, thanks for looking.
I'm writing a program that creates and prints out schedules for a sports league. I am having a very annoying problem with drawString().
The incredibly annoying part of this is that one method in my object prints its strings correctly, whereas exactly the same code in another method doesn't print anything.
O.K., here's the code for calling both these methods:
drawLeagueNameWeek ( g2, leagueWeek );
drawLeagueGameList ( g2, leagueWeek );This code comes from the print method of my object, which implements Printable, and g2 is the Graphics2D object that I typecast from the Graphics object in print().
Here's the text of the first method, drawLeagueNameWeek, which works perfectly.
void drawLeagueNameWeek ( Graphics2D g2, int weekNumber )
// This method draws the name of the league and the current week
// being printed at the top of each page. It'll be nicely centered,
// as well.
String leagueNameString, leagueWeekString;
FontRenderContext leagueContext;
int fontSize;
double fontXCenter;
float xValue, yValue;
leagueNameString = printRecord.getLeagueName();
leagueNameString = leagueNameString + LEAGUE_TITLE_STRING;
// I need the plus one because of 0..n array offsets. Trust me, it's necessicary.
leagueWeekString = WEEK_TITLE_STRING + Integer.toString( weekNumber + 1 );
Font leagueFont;
// First, create the font
fontSize = (int) Math.round( divisionSize / 2 );
leagueFont = new Font ("Serif", Font.BOLD, fontSize );
g2.setFont ( leagueFont );
leagueContext = g2.getFontRenderContext();
fontXCenter = leagueFont.getStringBounds(leagueNameString, leagueContext).getWidth();
xValue = ( float ) ( myPF.getImageableX() + ( ( WIDTH / 2 ) - ( fontXCenter / 2 ) ) );
yValue = (float) ( myPF.getImageableY() + ( divisionSize ) );
System.out.println("xValue and yValue for leagueNameString" );
System.out.println("xValue -- " + xValue + ", yValue -- " + yValue );
g2.drawString ( leagueNameString, xValue, yValue );
// Having drawn the League Name, now draw the league week under it.
fontXCenter = leagueFont.getStringBounds ( leagueWeekString, leagueContext).getWidth();
xValue = ( float ) ( myPF.getImageableX() + ( ( WIDTH / 2 ) - ( fontXCenter / 2 ) ) );
yValue = ( float ) ( myPF.getImageableY() + ( 2 * divisionSize ) );
System.out.println("xValue and yValue for leagueWeekString" );
System.out.println("xValue -- " + xValue + ", yValue -- " + yValue );
g2.drawString ( leagueWeekString, xValue, yValue );
} // end of drawLeagueNameWeekThis method, as I say, draws the text that i want beautifully. It's nicely centered at the top of the page, and prints out the week number correctly.
The second method, drawLeagueGameList(), though, doesn't seem to do anything. The println statements all print, they show me the strings and ints and everything else that I want and everything seems fine.
Except the calls to g2.drawString() simply refuse to print anything. And I have no idea why.
Here's the code for that one.
void drawLeagueGameList ( Graphics2D g2, int leagueWeek )
// This method is the heart and soul of the BasicBBPrinter class.
// One thing to keep in mind, I can only print 5 games per page, so
// I need to keep track of what games to print next.
// That information in stored in the variable gameCount.

gameContext = g2.getFontRenderContext();
numberGames = printRecord.getNumberGames( leagueWeek );
// First, create the font
//          fontSize = (int) Math.round( divisionSize / 3 );
          fontSize = 30;
System.out.println("fontSize is " + fontSize );
gameFont = new Font ("Serif", Font.BOLD, fontSize );
lineSpacing = Math.round ( divisionSize / 3 );
g2.setFont( gameFont );
g2.setColor ( Color.BLACK );
pageGameCount = 0;
// Since the league title and the league week take up the top two divisions,
// I need to make sure the other games get the proper offset. Each game
// gets two divisions for space.

From the trace lines, my team strings seem to be being built perfectly, my x and y locations seem to be fine, since I'm using values less then the width and height, and the text in drawLeagueNameWeek(() works fine, but it simply refuses to print anything that's in drawLeagueGameList, even the test lines.
I even tried copying all the code from drawLeagueGameList into drawLeagueGameWeek and, while all the game week stuff printed correctly, the gameList stuff still refused to do anything.
I've been working on this for three or four days and have no idea at all what might be wrong. I figure it's something simple and stupid, but I can't seem to find it.
Any and all help is appreciated.
And if you need any more information on anything, let me know.
Thanks again.

Hi, again.
I think I managed to solve this problem with help from another friend, and I'll post it here in case somebody with a similar problem comes across my post.
I've managed to get drawString to draw the strings in drawLeagueGameList by removing the while loop from around them.
This requires that I rebuild this method as a series of if-else statements, but I'm certinally willing to do that if that's what it takes to get it to work.
I still do not know why drawString isn't working inside that loop, it might be a bug of some kind in drawString or in the Graphics2D library.
If anybody has any idea on why it didn't work in the loop, I'm still interested in hearing theories.
Thanks again for looking.

Drawing a String using Graphics Object

When I am printing a long String using the following method
String currentMessage // The size of the String is large
g.drawString(currentMessage, x, y, Graphics.BOTTOM | Graphics.HCENTER);
only the middle of the String is shown on the sreen.The first and last parts are stripped off because of the size of the screen.
Anyone knows how to specify the size of the font, or how to force the string to continue on a new line if its size is bigger than the width of the screen?
Cheers

There is not native support for line wrapping in drawString().
You can change the font by using g.setFont(),
Create your on font, and specify the font size as small.
The Font class includes a method to determine the length of a string. You can use this method to check the length of the String if the string is longer than the screen width, you can break the String into parts (substrings) and draw each of the parts.
Alternatively, you can use this line wrapping class http://hostj2me.com/appdetails.html?id=6

How find shape containing all pixels in string drawn at angle?

I've drawn a string on a JPanel at an angle using the code below. I want the mouse to turn into a hand when hovering over it but I don't know how to find the shape that an angled string comprises. (I can do it if it's written horizontally). How would I calculate that?
double theta = Math.toRadians( angle );
AffineTransform transform = AffineTransform.getRotateInstance( theta );
( ( Graphics2D ) graphics ).setTransform( transform );
graphics.drawString( text, x, y );

For the String you can create a Rectangle where the String is contained when it has no rotation. After that you can create Area (see java.awt.geom.Area) from the Rectangle and use transform() method of area to get a rotated one. Then just use contains() method.

Very Urgent - Draw a string in a rectangle with a given width

Hi
I have a jtextArea and I have set its width to a fixed value. I set the wrap line property to tru and the word wrap true so as if the word is too large it will be displayed on the next line of the jtextArea. I read a string value and give it to the JTextArea.
I want to know the height of the JTextarea after the String is wrapped in it. The string may be of a single line but after it is wrapped, in the JTextArea it may appear as multiple line. All the methods of the JTextarea tell me that the JTextarea has a string of one line and the rectangle it returns does not match the true one.
I want to know either the real values of the rectangle after the string is wrapped or the number of lines the string is divided as it appears in the textareas.
My email address is [email protected]

Help with drawing strings on JFrame?!?!

Hey guys, I'm really new to Java (just started AP Comp Sci last month), and we had a project to build a Mastermind application using numbers, which I did. However, I'm trying to learn more on my own, and was hoping to use the example code my teacher gave me to output what I want to say to a JFrame instead of just the command prompt.
Here is the code for my Mastermind class:
Code:
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
public class Mastermind extends JFrame
     public static void main(String args[])
          int master[] = new int[4];
          int win = 0;
          for(int x = 0; x<4; x++)
               master[x] = (int)(Math.random()*10);
          System.out.println();
          do {
               int guess[] = new int[4];
               int countMaster[] = new int[4];
          String numguess = JOptionPane.showInputDialog("Enter your guess (4 digits, please)");
          for (int x = 0;x<4;x++)
               guess[x] = (numguess.charAt(x)-48);
          int correctlyPlaced = 0;
          int correct = 0;
          for (int x = 0;x<4;x++)
               if(master[x] == guess[x])
                    correctlyPlaced += 1;
          for (int x = 0; x<4;x++)
                         for (int y = 0; y<4;y++)
                              if((guess[x]==master[y]) && (countMaster[y]==0)) {
                                   correct++;
                                   countMaster[y]=1;
                                   y=5;
          System.out.print("Guess:\t\t\t");
          for (int x = 0;x<4;x++) {
               System.out.print(guess[x]);
          System.out.println();
          System.out.println("Correct:\t\t"+correct);
          System.out.println("Correctly Placed:\t"+correctlyPlaced);
          if (correctlyPlaced==4) {
               win=1;
     } while(win<1);
     System.out.println("You win!");
          System.exit(0);
And here is the example code that my teacher gave me for how to draw a string on a JFrame:
Code:
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class Fonts extends JFrame {
     public Fonts()
          super("Using Fonts");
          setSize(420,125);
          show();
     public void paint(Graphics g)
          super.paint(g);
          g.setFont(new Font("Serif", Font.BOLD, 12));
          g.drawString("Serif 12 point bold.",20,50);
     public static void main(String args[])
          Fonts application = new Fonts();
          application.setDefaultCloseOperation (
               JFrame.EXIT_ON_CLOSE);
I would like to be able to put "Guess," "Correct," and "Correctly Placed," on a JFrame, with their respective variables. Any ideas? Thank you!!!

And DrClap, I get that, but I'm not sure how to put my existing code into the class file that uses the JFrame.You wouldn't put your existing code in there. Your existing code is designed to run as a console app and most of it is concerned with the machinery of getting input from the user. If you want to write it as a Swing app, then you wouldn't need any code which writes to a JFrame in the first place.
So if your goal for learning on your own is to write GUI applications instead of console applications, then go off and read the Swing tutorials. Right now you're going down the wrong road. However if you're trying to learn something else on your own (I can't tell what that might be) then explain what it is you're trying to learn.

How to find the total length of the string drawed in a rect?

Hello Everybody,
I am drawing a string in on one rect using drawInRect method. This drawInRect method gives us a return value as size of the rect. I need length of the string that is did draw in that rect, but didn't find any api to do this.
Can anyone tell me , how find the length of the string which we did draw in rect?
Any help regarding this issue , is highly appreciable.
Thanks,
Pandit

Hi Adreas,
First of all, very thanks for the response.
Actually , I am looking for other thing. Using drawInRect method I am drawing contentString in self.rect like below.
//code
[contentString drawInRect:self.rect withFont:[UIFont fontWithName:@"Verdana" size:14.0] lineBreakMode:UILineBreakModeWordWrap alignment:UITextAlignmentLeft];
//End
My contentString is much larger string, so I am not able to draw it in rect(length: 320.0 height: 460.0) completely. My rect is showing only a part of a contentString. So I need to get that part of string which did draw in the rect, so that I can process my contentString to get the remaining string to draw it a next rect.
The above code statement is returning me the CGSIZE , it is giving the size of the rect but not giving any information of the string which get draw in that rect.Do you have any idea how to do this?
Any information on this is highly appreciable.
Thanks,
Pandit

Drawing a color string with swing and Graphics2D

hi guys,
I am trying to draw a string on a JPanel, and can do so successfully with plain boring text using drawString(string, int, int). How can I change the font and color? Thanks!

Read the API for java.awt.Graphics.

Draw string in center

Hi,
I would like to draw a string into center of my own Lable component. How can I know what position of x , y ?
I'm using g.drawString(mytext, x , y ); in paintComponent() method.

I guess you could use one of these:
- Font.getStringBounds()
- TextLayout.getBounds()
- FontMetrics.getStringBounds()

Havin probs drawing a simple string

hi 2 all
i've got this simple applet,but it doesn't really what i want!i only see a gry rect!but he has to draw a string!
import java.applet.*;

import java.io.*;
import java.awt.*;
public class CCounter1 extends Applet {
Font anzeiger;
public void init() {
anzeiger=new Font("Arial",Font.BOLD,16);
public String readFile(String f) {
try {
String zahl1="";
String aLine = "";
URL source = new URL(getCodeBase(), f);
BufferedReader br =new BufferedReader(new InputStreamReader(source.openStream()));
while(null != (aLine = br.readLine()))
zahl1.concat(zahl1);
br.close();
return aLine;
catch(Exception e) {
e.printStackTrace();
return null;
public void paint(Graphics g){
setBackground(Color.gray);
g.setColor(Color.white);
setFont(anzeiger);
g.fillRect(100,100,100,100);
g.drawString(readFile("besucher.hansi"),10,20);
g.drawString("Hallo",200,200);

You set the color to white... fill the area and then paint a string (with the same white color)
first... set a color... fill it... then set another color... draw your string... done

How to draw string vertically?

Hi,
The java drawString() method draws string horizontally by default, but I want to draw the string vertically, see an example below: I want to draw the string "abcdef" as below format:
a
b
c
d
e
f
so, I thought of the AffineTransform, but I can not work it out.
Who can help me? If you have other ways, they are welcome too.
Thanks. Robin

Zooming on a large drawing

Can someboby, please, help me to manage the zooming of an area of size 30x30 pixels of a large drawing.
The drawing contains a number of shapes, but in the code that I will be posting I will be using only one shape. The drawing is made up of more than 500 shapes, reason for which has to be scaled to fit on a monitor.
What I would like to happen is : when mouse clicked anywhere on the drawing a small area of 30x30 pixels should zoom out so the label for the shape to be clear. At this zoomed stage I should also be able to click on a chosen shape and open some frame.
I will post the code I wrote bellow. Could somebody please be so kind and help me!

you probably want to do something like this.
Override your paint method in your zoom window
public void paint (Graphics g) {
Graphics2D g2 = (Graphics2D)mainPanel.getGraphics();
g2.translate(x,y); //whereever you want to start your zoom area
g2.scale (dx, dy);
}
