Width and height of display?

I was wondering... what are the actual width and height of my 14.1 iBook's screen?

14.1 inches diagonal. Try using a tape measure and measure it. I dont have a 14" i Book or I'd check for you.

Camera Image Display - changing width and height.

Ok, so I wrote this simple program, but for some reason i cant control the offsets, width and height (attributes related to the image display on front panel). When i go to MAX, i am able to change these attributes, why cant i do it in labview? Any ideas?

You need to put the width and height controls inside your loop to adjust while running.
From the image you provided, the width and height are set once outside the loop, and then you sit in the loop, so they can't be adjusted again.

How to change the width and height of the visible part of the of the report

I have define a report with paper size 'Letter', orientation 'landscape' and 30 columns. Dynamically I am changing width of columns and suppressing many columns of the report.
Mostly using first 16-20 columns and others get suppressed.
Now problem is that when navigating the report thru crystal viewer, a huge blank spaces getting display on right of the report. When we take jump to some part of report thru navigation tree, the whole report gets shifted to left and only blank part is visible and it is required to scroll left.
Even printing is not working correctly.
Is there any way to change the width and height of the visible part of the report in the viewer thru .net classes? Setting the width and height of the report in Load event handler doesn't help.
Example: CrystalReportViewer1.Width = 200; - is not helping.
Is there any other solution?
Please let me know.
Thanks

Hi Yogesh,
Your suggestion 'reportDocument.PrintOptions.PaperSize=PaperSize.PaperLedger;' along with 'PaperOrientation' setting as follow works fine. I tried to switch between Landscape and Portrait depending on report width.
reportDocument.PrintOptions.PaperOrientation = PaperOrientation.Landscape;
But problem with crystal viewer remain as it is.
While navigating report thru crystal viewer, when we take jump to some part of report thru navigation tree, the whole report gets shifted to left and it is required to scroll left.
Thanks for your very good suggestion.

How can I get the image width and height stored in database?

Hi!I write s servlet to display images store in database.but how can I get the image width and height?

Have you tryed using PJA or a similar library?
I presume you get java.lang.NoClassDefFoundError on the line :
Toolkit.getDefaultToolkit();?

Nested canvas in GridLayout can't get its width and height

Hello,
I have a class entitled DisplayCanvas, which will accept some parameters from an invocation in another class including a shape and message parameters. These parameters must be centered in the instance of DisplayCanvas.
For some reason, when I use this.getWidth() and this.getHeight() within my DisplayCanvas class, I get 0 and 0! I need the width and height in order to center the parameters the user will enter.
Why does the width and height result at 0? What can I do to get the width and height?
In my DisplayCanvas class notice the lines:
canWidth = this.getWidth();
canHeight = this.getHeight();
For some reason the result is 0 for each!

Sorry for glossing over your code sample, particularly as it looks like one of the best I've seen so far on the forums, but I'm pretty sure the answer you are looking for is as follows:
Java doesn't render a component until paint() is called so until then you are not going to have any size settings because the jvm simply doesn't know how big the visual component is. This makes sense when you think about what the jvm is doing. The layout manager controls the display of the components depending on the settings it is supplied. So until it knows how many components you want, where, what kind of spacing, etc, etc, etc, how can the size be determined.
The true cycle of events is therefore:
create an instance of DisplayCanvas,
add it to your container,
make the container visible (which renders the component),
get the size of the DisplayCanvas instance.
You are being hampered because your desired chain of events is:
create an instance of DisplayCanvas,
get the size of the DisplayCanvas instance,
add it to your container,
make the container visible.
This state of affairs is highly annoying and then leads to the next question "what do we do about that?". There is a cunning trick which is to get the jvm to render the component to an off-screen image, thus calculating the dimensions of the component so that you can do precisely the kind of enquiry on the object that you have been looking for. It should be noted that this may not be the visual size for all the reasons given above, but it is the "preferred size" for the component. Check the Swing tutorials and have a look at the section on Layout Managers for a run down on what that means.
Anyway, we can use this handy code sample to determine the preferred size for your component. Notice the call to "paint()" (normally you would never make a direct call to paint() in swing) and the "g.dispose()" to free resources:
package com.coda.swing.desktool.gui;
import java.awt.Component;
import java.awt.Dimension;
import java.awt.Graphics2D;
import java.awt.image.BufferedImage;
public class PaintUtil
     public PaintUtil()
          super();
     public static Component paintBuffer(Component comp)
          Dimension size = comp.getPreferredSize();
          comp.setSize(size);
          BufferedImage img = new BufferedImage(size.width, size.height, BufferedImage.TYPE_INT_ARGB);
          Graphics2D g2 = img.createGraphics();
          comp.paint(g2);
          g2.dispose();
          return comp;
}Before you make a call to getWidth() or getHeight() put in a call to "PaintUtil.paintBuffer(this);" and see what happens.
By the way, I can't claim credit for this code ... and I really wish I could remember where I got it from myself so I can thank them :)

Does anyone know if there is a way that I could get the width and height of an image to be displayed in a JSP.

Image has methods to get the width & height.

Fix width and height of accordion

Hi All
I am building an application using jquery accordion on region 3 of page 0. In each subregion I have a treeview and when a node is choosen shows details about this node. My issue is how to fix width and height of accordion. I tried with jquery tabs instead of accordion and I put this on region header 'style=\"overflow-x:auto;display:block;max-width:340px;min-width:340px;overflow-y:auto;max-height:450px;min-height:450px;";" ', and closing tag at region footer and it worked.
Any idea?
Thanks a lot.

Hi Jitu
Thank you for your replay but it didn't work as I need.
I made the following test. I put on region attribute \style="width:350px;". When each subregion of accordion has only a treeview, it didn't work. When I created another subregion into accordion with a simple report, it worked fine.
I don't know what is going on and also how to fix it.
Any other idea?

Sizing a scrollPane to fit its contents' width and height

Hi,
I have a MC loaded into a ScrollPane and have attempted to
detect the MC's width and height and use that to set the size of
the scrollPane per the documentation at
Adobe
Live Docs. I am probably not adapting the code correctly (well,
duh), but what I have isn't working and I don't know why. Does
anyone around here have a clue? Thanks in advance.

OK, the forum ate my code :(
Not sure how to get it to display. Feel free to close the topic as it doesn't make sense. I'll ask elsewhere.
Thanks,

How to calculate actual selection or group width and height with clipping

If a group has clipping paths then the height and visible bounds will include the dimensions of all paths selected including the clipped or hidden paths.
However, the width and height shown on the width and height of the AI detail boxes for the selection shows just the visible dimensions.
I want to retrieve the same values that is shown on the screen when a group is selected.
It is somewhat counterintuitive that the "visiblebounds" property does not show just what is visible.
I'm scaling the visible content of a selection to fit within another path but I need to be able to calculate the dimensions of the only what is visible after clipping.
What do you have to do with scripting to get these values? Go through all of the path items in a group recursively and save the min and max values of any visiblebounds for clipping paths? Any better alternatives that I don't see?
Thanks for any help!

I ended up using the visible bounds for both scale and position as I also discovered that attempting to position a group with the position method would also result in missing the mark. The top and left (x,y) bounds I calculated without the clipped dimensions needed to be used to offset the actual position where I wanted the visible paths to be displayed.
The functions I used ended up looking like so:
function GetPoints(dblInch)
     var dpi = 72;
     return dblInch * dpi;
function getRealVisibleBounds(grp) {
     var outerBounds = [];
     for(var i = grp.pageItems.length - 1; i >= 0;i--) {
          var bounds = [];
          if(grp.pageItems[i].typename == 'GroupItem') {
               bounds = getRealVisibleBounds(grp.pageItems[i]);
          else if((grp.pageItems[i].typename == 'PathItem' || grp.pageItems[i].typename == 'CompoundPathItem')
               && (grp.pageItems[i].clipping || !grp.clipped)) {
               bounds = grp.pageItems[i].visibleBounds;
          if (bounds.length > 0) {
               outerBounds = maxBounds(outerBounds,bounds);
     return (outerBounds.length == 0) ? null : outerBounds;
function positionVisible(grp,x,y)
     var bounds = getRealVisibleBounds(grp);
     var newX = GetPoints(x) + (grp.left - bounds[0]);
     var newY = GetPoints(y) + (grp.top - bounds[1]);
     grp.position = [newX,newY];
function maxBounds(ary1,ary2) {
     var res = [];
     if(ary1.length == 0)
          res = ary2;
     else if(ary2.length == 0)
          res = ary1;
     else {
          res[0] = Math.min(ary1[0],ary2[0]);
          res[1] = Math.max(ary1[1],ary2[1]);
          res[2] = Math.max(ary1[2],ary2[2]);
          res[3] = Math.min(ary1[3],ary2[3]);
     return res;
and were called like so:
var doc = app.activeDocument;
if (doc.selection.length > 0) {
     var grpOriginal = null;
     if(doc.selection.length == 1 && doc.selection[0].typename == 'GroupItem') {
          grpOriginal = doc.selection[0];
     else {
          grpOriginal = doc.groupItems.add();
     doc.selection = null;
     if(grpOriginal.layer.name != 'approval') {
          grpOriginal.move(doc.layers['approval'],ElementPlacement.PLACEATEND);
     var artBounds = getRealVisibleBounds (grpOriginal);
     var artWidth = artBounds[2] - artBounds[0];
     var artHeight = artBounds[1] - artBounds[3];
     var imprintHeight = GetPoints(0.625);       // 0.625 is new height, hardcoded for demonstration
     var imprintRatio = imprintHeight / artHeight;
     var section = doc.layers['sectionLeft'];    // section where I placed the art
     var grpArt = grpOriginal.duplicate(section,ElementPlacement.PLACEATEND);
     grpArt.resize(100.0 * imprintRatio,100.0 * imprintRatio);
     grpArt.move(section,ElementPlacement.PLACEATBEGINNING);
     grpArt.selected = true;
     positionVisible(grpArt,0.0,16.75);          // x & y hardcoded for demonstration
else {
     alert('artwork needs to be selected');
I'm new at this so are there any better options to do these things?

Getting maximum width and height of frame

In my Flash CS4 application I have a problem working out the maximum x and y coordinates of the display objects that have been created in a frame using the frame editor. This is the sequence
1. Using the frame editor on the timeline, I create a keyframe with a mixture of library symbols and text/graphics which are not symbols.
2. In AS3 I take all of the screen objects and make them children of a Sprite that I created in my AS3 script. I then delete the objects off the screen and pass the parent Sprite to a class that I use to manage the screen.
3. In the manage screen class the first thing I do is go through the child display objects to work out the maximum x and y coordinates so that I can centralise them on the screen later on.
The problem is that I'm not able to work out the maximum x & y coordinates correctly. There is no problem with the symbol objects, I just add the x and width for example, for the maximum x coordinate. But for the non symbol objects this does not work. They appear to be combined in some way and the x/y & width/height do not seem to correspond to anything in the frame editor.
Is there a writeup anywhere on how Flash manages the graphics/text obects which are not symbols and are created by the editor in keyframes on the timeline? Finding the maximum x and y coordinates of a screen full of objects should be fairly simple, but I cannot see a way of doing it at the moment.

On my JPanel I want to draw stuff, and for this I need to know the > > width and height of the JPanelIf you are drawing stuff, then you are in control off
how big you want to draw the stuff. You can make the
panel as big or small as you want and do your drawing
accordingly.But doesn't the Layoutmanager of the frame set the size of the added panel according to the rest of the layout, or am I way off here?
Do I need to setPreferredSize() or anything on thepanel before pack()?
Try it and see what happens. If you don't give the
panel a size then the pack() method basically ignores
it as you have found out.Perhaps if I gave an example, you could point me in the right direction? The code below creates a JPanel of size 200x200, and draws a ball at a random spot on the panel. But since the frame is way bigger than 200x200 the panel gets stretched by the layoutmanager (right?). So what I really want to use when I calculate the x and y position is the width and height of the panel as it is displayed in the frame.
Here goes:
import javax.swing.*;
import java.awt.*;
class MyFrame extends JFrame {
public MyFrame() {
    super("A ball");
    JPanel panel = new JPanel();
    panel.setSize(200, 200);
    int x = (int)(Math.random()*200);
    int y = (int)(Math.random()*200);
    panel.add(new Ball(x, y));    // Object Ball draws a ball at x,y
    getContentPane().add(panel, BorderLayout.CENTER);
    setSize(640, 480);
    show();
public static void main(String[] args) {
    new MyFrame();
}

How to get the width and height of the selected rectangle

Hi,
I need to get the width and height of the selected rectangle in indesign cs3 and display the values in a dialog box for user verification.

Hi Saran,
InterfacePtr<IGeometry> itemGeo ( objectUIDRef, UseDefaultIID() );
PMRect ItemCoord = itemGeo->GetStrokeBoundingBox();
PMReal width = ItemCoord->Width();
PMReal height = ItemCoord->Height();

Changing af:messages width and height

Hi gang
Does anybody have a suggestion how I can expand the default width and height of the af:messages popup under JDev 11.1.1.2.0? From what I can see there are no styles defined in the skin, no properties on the component, and the inline style width/height properties are ignored.
Your help appreciated.
Regards,
CM.

I have to agree with 9 of the 14 respondents Keyshia Cole's new nose is indeed natural looking :-)
The problem we're getting is two fold:
a) Occasionally our error messages have long words, the messages tag isn't hard wrapping, and this is resulting in a horizontal scroll bar.
b) Sometimes the number of messages displayed is greater than the vertical space, so we get a vertical scroll bar.
c) Sometimes both, which looks cr@p.
The combination can make the app less user friendly as the user has trouble assessing/reading the error messages.
While we can do some minor tweaking to minimize word length and number of error messages, the preferred method would be just to increase the size of the dialog.

How to create a map that is larger than the game in width and height?

hi,
i wounder how i can create a map(not the design) that is larger than the game in width and height, part of it will appear in the main page and anther part you can move to it after you press the arrow symbol, but the map is just one image so i want put it in line and out line the game page, and the out line part includes buttons and symbols the player can use, but it will be in line and the other part will be out line when you press the left arrow or the down arrow, how i can do that?
and is that possible to animate it so when the player press the arrow, will give it action to start the animation in one sec, i know how to animate it if that possible but i don't know which code i will use for the mouse click with the arrow symbol, and how to use the same code in the same symbol to start anther animation depending on which part of the map is on?

I don't know a lot about mask and masked layers and how to work with the normal layers beside i will use some 3D graphics but not in the background, i will explain all this to you to be more clearly.
first i am using action script 3.0
close ex,
you have 2d map"image" 900*300 pixel.
this image contains some 2d symbols when you click will go to anther normal map (anther normal layer) so they must appear.
your game 320*320 px, and the place the map will show on 300*300, and there's basics objects will be in most pages including the page that show the map so i don't know a lot about how this will work with mask layers.
so you can only see the left side of the map image and what it contains, while there's two arrows one to the left and one to the right there's three cases here,
first when it show the left side(start from x:0 to x:300), the left arrow will not active when you press and the right arrow will start an animation that make the map image move to the mid side in one sec when you press.
in mid side (start from x:301 to x:600) the same left arrow will active when you press to send you back to the left side while the same right arrow will be active to send you not to the mid side but to the right side,
when moved to the right side the same left arrow will be active to send you to the mid and the right will not active when you press and depending on that,
first how to make the large image appear with the three sides in the same place without effecting the other objects "like disappearing them" ?
and the codes i need in the same left or right arrow symbol to make different actions with the same symbol when clicked depending on which part of the map is on.

Java returning incorrect values for width and height of a Tiff image

I have some TIFF images (sorry, I cannot post them b/c of there confidential nature) that are returning the incorrect values for the width and height. I am using Image.getWidth(null) and have tried the relevant methods from BufferedImage. When I open the same files in external viewers (Irfanview, MS Office Document Imaging) they look fine and report the "correct" dimensions. When I re-save the files, my code works fine. Obviously, there is something wrong with the files, but why would the Java code fail and not the external viewers? Is there some way I can detect file problems?
Here is the code, the relevant section is in the print() routine.

Figured it out. The files have a different vertical and horizontal resolutions. In this case the horizontal resolution is 200 DPI and the vertical is 100 DPI. The imgage width and height values are based on those resolution values. I wrote a section of code to take care of the problem (at least for TIFF 6.0)
 private void setPageSize(int pageNum) throws IOException
 IIOMetadata imageMetadata = _reader.getImageMetadata(pageNum);
 //Get the IFD (Image File Directory) which is the root of all the tags
 //for this image. From here we can get all the tags in the image.
 TIFFDirectory ifd = TIFFDirectory.createFromMetadata(imageMetadata);
 double xPixles = ifd.getTIFFField(256).getAsDouble(0);
 double yPixles = ifd.getTIFFField(257).getAsDouble(0);
 double xRes = ifd.getTIFFField(282).getAsDouble(0);
 double yres = ifd.getTIFFField(283).getAsDouble(0);
 int resUnits = ifd.getTIFFField(296).getAsInt(0);
 double imageWidth = xPixles / xRes;
 double imageHeight = yPixles / yres;
 //if units are in CM convert ot inches
 if (resUnits == 3)
 imageWidth = imageWidth * 0.3937;
 imageHeight = imageHeight * 0.3937;
 //convert to pixles in 72 DPI
 imageWidth = imageWidth * 72;
 imageHeight = imageHeight * 72;
 setImgWidth((int) Math.round(imageWidth));
 setImgHeight((int) Math.round(imageHeight));
 setImgAspectRatio(imageWidth / imageHeight);
 }

What are the units of "Width" and "Height" of a Shape?

What are the units of "Width" and "Height" properties of a Shape when programming?
Something odd like points or twips or tweedles or nibbles?
http://www.ransen.com Cad and Graphics software

Width and Height are properties of type Single; they represent the dimensions of the shape in points, where 72 points = 1 inch.

Width and height of display?
