Please help Verticle line problem

Please help I have worked on this for hours below is my code. I need to create a face and I have a problem getting my g.drawline in the right place. I need it in the middle between the two eyes and not matter what I do it won't work. Could you help, please.
import java.awt.*;
import javax.swing.*;
public class Face extends JFrame {
     public Face(){
          super( "Face" );
          setSize( 300, 170 );
          setVisible ( true );
     public void paint ( Graphics g ){
          super.paint( g );
          g.setColor( Color.yellow );
          g.drawArc( 100, 45, 80, 80, 0, 360);
          g.setColor( Color.blue );
          g.drawArc( 120, 70, 10, 10, 0, 360);
          g.setColor( Color.blue );
          g.drawArc( 150, 70, 10, 10, 0, 360);
          g.setColor( Color.magenta );
(this is the nose)     g.drawLine ( 90, 147, 90, 180 ); THIS IS THE LINE I HAVE A PROBLEM
          g.setColor( Color.red );
          g.drawArc ( 110, 55, 60, 60, 0, -180 );
     public static void main(String args[])
          SmileyFace application = new SmileyFace();
          application.setDefaultCloseOperation(
                    JFrame.EXIT_ON_CLOSE );
I have changed the int to every possible number and it just won't work for me what am I doing wrong

try:
g.drawLine ( 140, 85, 140, 110 );
When you drew your head you specified g.drawArc( 100, 45, 80, 80, 0, 360);
What you are really saying is:
a) position the circle inside an imaginary rectangle with the top left corner at (100, 45) and make the width of the rectangle 80 and the height 80.
b) the center of this rectangle is
x = 100 + 80/2 = 140
y = 45 + 80/2 = 85
c) therefore draw a circle using (140, 85) as the center point (which is where I started your nose)
Add the following line to your program and you will see how the head fits into the rectangle:
g.drawRect(100, 45, 80, 80);
Hope my explanation helps.

Please help me line up my cells or tables

I cannot ge tthe elements on my webpage to line up I have
moved them around all to no avail the page is:
http://www.abea.cc/aboutus.html
notice the offset between the headers and the white body. Could
someone please help me I am lost. I can line them up perfectly in
my preview but always offset when I look at them online.I am using
dreamweaver cs3.

This image (and others like it) are what's messing you up:
http://www.abea.cc/images/The-Bay-Shortest-Header_10.jpg
Adjust the images to not show any of the black outside of the
white line, then you'll have an easier time adjusting the table
below it. Once you fix the image you'll have to adjust the table
structure.

Please Help! Line Length Outside of Window

I'm not stating this properly. But suddenly, my Safari windows have content which is not all contained therein. I can only read part of it. Same problem with my e-mail.
Unable to shorten length of lines in e-mail, and unable to adjust window. Have gone to Preferences/Appearance, etc.
Please tell me how to explain this problem, if I am not being clear.
Thanks for any help you can offer.

I would suggest you revisit the Universal Access to double check that you did what I suggested.
Also make sure that "Use Grayscale" is not checked in Universal Access.
Your line length problem might be caused by your changing the resolution of your monitor. What kind of monitor are you using and do you know what its advertised resolution is? Something like 1280x1024 pixels, for example.
I notice in an earlier post in another forum that you reported the following, which I will quote for the benefit of those joining this thead later:
"I'm using a MacMini OS 10.2.9. Everything was great, then on start-up all was different. My Desktop picture had disappeared, everything was in purple etc. My e-mails have long line length and I am unable to shorten. Have looked at preferences etc. and nothing helps. (I put back the desktop picture, but everything else is beyond me.)
I don't recall if I recently updated software, but suspect that is why everything is messed up.
Sorry if this has been asked before, but I'm quite frustrated. This font is not what I thought was selected, either! "
I'm a bit confused about your reporting OS 10.2.9. Is that a typo? I think Minis never shipped with anything lower than 10.3.x. Your signature reports 10.4.6.

Please help: Extra Line Space after bolded word

I am in the process of editing a book manuscript in MS Word 2010, and there is an annoying problem that I cannot solve. I have tampered with all the line spacing options, but I'm at a loss.
When I bold a word, it introduces an extra little line space before the proceeding line. When I unbold the word, the space goes away. Has anyone encountered a similar issue? And is there an easy fix?
Thanks very much,
Jon

Are you saying that the line spacing changes when you apply bold formatting? Try a different font. Or you could specify a fixed value for line spacing (choose the "Exactly" option in the Paragraph dialog box).

PLEASE HELP! Guitar line in on Audigy 2 ZS not working

i have a sound blaster audigy 2 ZS platinum pro. In every program i try to use (FL 4, reason, krystal, ...) i can not even hear my guitar when plugged in to the sound card. I have tried the obvious, making sure i'm not in digital only mode, checking the cables. Some one please help.

Does Line-In work w/ normal line sources?
You propably need a pre-amp for guitar input through Line-In port but, if the port you're using is a Hi-Z port (you find this information from Audigy User's Guide) then, it should work even w/o additional pre-amp.

Here are my last 3 duke dollars. Can someone please help me draw a line?

I have been BEATING my head on this for well over a week now. I'm new to Java2D and I cannot find even one example of this simple little thing that I am trying to do. Not one.
All I want to do is draw an image, zoom that image, then draw some lines on that image, and then zoom it and have those lines show up where they should.
For example, we have an image which has been zoomed. No lines are yet drawn on it.
A line is added.
The image is then zoomed in or out one more time.
How do we get the line to remap to the newly zoomed image?
What I am doing is:
0) Load up an image from a file.
1) Create a zoomed image by using the Image.getScaledInstance() method.
2) Create a BufferedImage with the width and height of the image AFTER the zoom has taken place.
3) Create a Graphics2D object by the createGraphics from this BufferedImage.
4) Place the image into the BufferedImage by doing a BufferedImage.drawImage
5) Select two points to be the start and end of the line.
6) Draw the line using Graphics2D.drawLine(start.x, start.y, end.x, end.y).
7) Zoom the image again (using the Image.getScaledInstance() method.
8) Create a new ImageIcon using the image from above and override its paintIcon method like this:
ImageIcon newIcon = new ImageIcon(newImage) {
public void paintIcon(Component c, Graphics g, int x, int y)
super.paintIcon(c, g, x, y);
zoom(); //<---- ZOOM call
Now in the zoom routine, what do I need to do to get the lines to draw at the proper location and size?
Remember, the points of the lines (stored in a list as home grown line objects) are in screen coordinates, not image coordinates since they are just click points
Note that when I use these points to draw a line, all is well (the line gets drawn where it should), but I have problems when I zoom the image.
Thanks!

Below is the documentation and method signature of
Graphics.drawImage(Image img, int dx1, int dy1, int dx2, int dy2, int sx1, int sy1, int sx2, int sy2, ImageObserver observer);The important thing to note is that it does scaling on the fly if the size dictated by the source co-ordinates is defferent than the size dictated by the destination co-ordinates. The source image is always left un-touched.
So basically your visual data is located in an offscreen image. You can draw a line on that. Then create a new image, get it's graphics and call drawImage(original_image, co-ordinates that cause it to scale how you like).
Then you can draw lines on the 2nd image, create a 3rd, ...etc
 * Draws as much of the specified area of the specified image as is
 * currently available, scaling it on the fly to fit inside the
 * specified area of the destination drawable surface. Transparent pixels
 * do not affect whatever pixels are already there.
 * 
 * This method returns immediately in all cases, even if the
 * image area to be drawn has not yet been scaled, dithered, and converted
 * for the current output device.
 * If the current output representation is not yet complete then
 * <code>drawImage</code> returns <code>false</code>. As more of
 * the image becomes available, the process that draws the image notifies
 * the specified image observer.
 * 
 * This method always uses the unscaled version of the image
 * to render the scaled rectangle and performs the required
 * scaling on the fly. It does not use a cached, scaled version
 * of the image for this operation. Scaling of the image from source
 * to destination is performed such that the first coordinate
 * of the source rectangle is mapped to the first coordinate of
 * the destination rectangle, and the second source coordinate is
 * mapped to the second destination coordinate. The subimage is
 * scaled and flipped as needed to preserve those mappings.
 * @param img the specified image to be drawn

Paintbrush tool reverts to color/fill none. Cannot draw/trace anything. Please help

Hello,
I am fairly new to Illustrator and need some help. I am trying to trace an image using the brush tool. I can get some lines in and for some reason the brush tool begins to revert to fill none effectively just making invisible lines. I have the parent image on its separate layer and the line art on another layer. Layers are unlocked. When I use the brush it will look as if it is deleting/erasing what is shown on both layers. The brush tool is effectively erasing what is there already instead of drawing.
I tried searching for a couple days now and the best I could find is this:
http://forums.adobe.com/message/4799313
I tried everything mentioned in the thread and it still isn't working. In fact I think the OP in that thread never really solved his issue too. I can barely even get my line art down please help! Thanks

Thanks rcraighead. I ended up just ctrl z-ing(is that even a work haha) back to a point were the brush worked. However I still dont know what happened. Thanks for your reply, if it ever happens again I will try it out.

PLEASE HELP!!!! Problem with my Huion H610n drawing tablet!!!

I recently purchased a drawing tablet which is the Huion H610N its working perfectly however when I opened photoshop cc I tried drawing in a blank canvas and Its not showing anything. I tried using the 'basic brushes' instead of my 'custom brushes' and it lets me draw and I can see it however the sensitivity is not showing when I draw using the 'basic brushes' the lines are just plain BOLD please help! I dont know why its doing this!

Try accessing the *System Preference* panel, named *Universal Access*;
then, note the choices within it include Mouse (among other) and click
on the Mouse section to check and see if _+the slider control+_ to change
the Size of the *Cursor icon* has been moved over to make it larger.
You can check/change several settings in Universal Access; also some
of these have keyboard shortcuts which may be engaged by a user,
by accident due to random use of a keyboard. Be aware of this, since
a pattern of changes when children use a computer may repeat; as
similar keyboard mistakes (or intentional odd results) use similar keys.
There are symbols representing keys used to engage Universal Access;
their icons in this control panel area of System Preferences should be-
come familiar to you, so when/if other odd visuals occur, check here.
Notice what the 'default' settings are, in the different U.A. panel areas.
This will help when you find another issue arise; a repeat is likely.
You may choose to set up a different user account in the Mac then have
it not allow full access to more than a few basic necessities, for a child.

8800, battery symbol with red line through it. Won't boot. Please help!!!

I recently bought a 8800 and when I inserted a battery, all I got was a battery symbol with a red line through it on a dim screen. I changed batteries, tried to charge it via USB and from a wall outlet to no avail. I tried cleaning the contacts and tried uploading t a new OS, but it wont recognize the phone being connected when it actually is.    I am at the end of my rope with this phone and can't figure out what else to do. Is it just gone? Please help me
Solved!
Go to Solution.

Leave the device to charge 2-3 hours, and then, still connected to the USB cable, remove the the battery from the device a few seconds and reinsert it. If it boots--leave it to charge to 100% (check Options > Status for the percentage).
If it doesn't boot--try using a wall outlet charger if you are not. If you are connected via USB to the PC, make certain that you have Desktop Manager (or the USB device drivers) installed, which you can download below.
