Object width and height

I realize this isn't exactly the way that Flex works, but I
need some help here:
I have a UIComponent class that has graphics drawn inside of
it (using graphics api and sprites). I need to be able to detect
the width and height of this component. Since flex doesn't count
these when i request clip.width or clip.height, I am totally stuck.
The thing I really don't get is why in FlexBuilder3 I can see
the dimensions I want right at the top of the variables list as
$width and $height, but there is no way to get to them! Argh!

I am having a similar problem, and this solution seems to not
be working.
I want to draw a box that's 10% height and 10% width of the
canvas (with a height and a width that's defined by percentages as
well) it's been drawn in. How do I do this? I can't seem to figure
out how to access these. My goal is to fill in boxWidth and
boxHeight in the code below.
My code for creating the rectangle is attached. Thanks for
any help.

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.

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 :)

Change the width and height of Landscape Layout for a report in 10G

Hi,
I'm new to reports and when i built the report in report builder 10g, the layout orientation was 'Landscape', hence I assumed that it'll be a landscape layout.
However, the width and height fields of the main section are 11 and 20 respectively. However, the height should ideally be 8.5. When i try to change it I get the following error message :
Layout canvas must remain large enough to fit layout objects.
Could you please tell me how to change the height of this landscape layout to 8.5 from 20.
The report has several main frames within a repeating frame, since the same report has to run multiple times.
Is it possible to have a repeating page across pages (crossing the horizontal margin) and hence have some of the main frames move down to the next page. I'm trying to do this to then be able to reduce the height of the main section of the report to 8.5. Its not working though because I'm getting the following error :
REP 1814 : Report cannot be formatted. Object "vertically" can never fit R_Main (the name of the repeating frame enclosing all objects)
Thanks,
Priyanka

To reduce the Hieght, first make the layout design fit into the new value..

Scripting TGetProperty width and height

Hello all,
i have a problem with the flash player in IE6 and FF2.
I have a html page with some flash movie elements on it.
I'm using SWFObject to bind the movies in.
After the onload event is fired, for each flash movie the
javascript function setCorrectSize4Flash will be called to resize
the html container element (embed, object tag) automatically by the
given width and height of the flash movie.
Therefore i'm checking if the movie is completely loaded and
if width and height is not undefined.
So if i'm getting width and height, i'm resizing the
container element to best fit in.
My problem is now, that the same movie used several times in
the same html page has every time different width and height
values. Sometimes the aspect ratio is 1:2 and sometimes it's 2:1.
Is this a problem of the flash player plugin or am i doing
something wrong.
Best regards,
bartmark

Thank you for your answer. But I don't understand:
The question is not the margin. I put in the body margin: 0; padding:0; and there is no margin.
I want to know the viewport: the width and height with the iPad in horizontal position and without the address bar.
This does not coincide with the 1024 x 768. (nor the 946 x 768 if I rest the address bar). I don't understand why
Thank you

[JS] Page item (rectangle frame) width and height

Dave, you are absolutely right (no surprise here) about always returning points. I'm not sure, but I think this may actually be an InDesign bug. At the end of the 'resolve' method the 'true' value is meant to indicate 'use ruler units', I believe. Having read the documentation, however, it does seem like certain transformation coordinate spaces functions only work in points.
To make this a more complete function, I've updated it to include a conversion to the current ruler units. I'm using the UnitValue object, and perhaps I'm misunderstanding something, but I cannot easily convert to a new UnitValue using the ruler measurements enumerations (it requires a string value to represent the target units). So I've had to include a switch function to get from the enumeration to the string value. Also, the UnitValue object does not seem to work with agates, and I haven't gone so far as to write my own conversion function for that, so the function has to exit with an alert if the user has agates as their ruler units.
If anyone can offer a more elegant way of dealing with this, it would be great. Or even better, some insight into why the resolve method does not seem to honour the ruler units. This _is_ getting a bit over-the-top for a simple width and height function. Maybe Adobe will consider just adding the property to the page item and putting us all (well, certainly me, anyway) out of our misery (I've put in a feature request).

Fullscreen published in flash - htm 100% width and height file is too big

file is 995 k and this would be my index.
When I publish on my provider the file doesn't open, probably
is too big as an index, i don't know.
Is there anyone there that could help me on that one?
Thank you

Well, firstly you have > 60 minutes of video, therefore, you should not use the 60 minute preset. Since you have 80 minutes of video, you're probably better off using the 90 minute preset.
Secondly, the presets assume that you are compressing your audio to AC3 with A.pack or Compressor 2 (depending on which version of DVDSP you're using). Uncompressed audio takes up lots of disc space and bandwidth.
Thirdly, the difference between the measured size in the Finder and the size in DVDSP is the difference between true gigabytes (how the Finder measures things) and billions of bytes (how DVDSP measures things). When you Get Info in the Finder, look at the number following the file size in GB... it's a larger number that's so many billions of bytes. This larger number should agree with the number you see in DVDSP. See the DVD FAQ for a discussion of this issue.

The line camera takes pictures of a single line over and over again as the object moves underneath it. You can build up an image of the object by stacking the lines in a larger image. If the line of the camera goes straight across the material being measured, you can measure the width with every line.
Yes, you can use a 100 meter cable with a GigE camera.
Red lighting is just the most convenient. Red is the easiest color to generate, and can easily be filtered to eliminate other light frequencies. Using colored lighting helps increase the contrast between the lighted areas and the background.
Your image indicates a max speed of 180 m/min, which would be 3 m/sec. If the camera acquires each line at 24 kHz, that is 24000 lines/sec. Divide the two to get 8000 lines/m, or 8 lines/mm. If your computer can keep up, you could make a measurement every 0.125 mm of your material. That probably isn't practical, but you should be able to make the measurements at the rate you need.
Almost forgot, the width is 1900 mm. With 4096 pixels wide, you get just over two pixels per mm. That means your measurements should be accurate to the nearest mm.

Units of parameters width and height passed in drawRect(int,int,int,int)

Units of parameters width and height passed in drawRect(int,int,int,int)

Units of parameters width and height passed in drawRect(int,int,int,int)They are just units in the User Space. Since you can change the
scale of the AffineTransform associated with your graphics object,
you can't be more specific than that.
Initially the claim is that the units are 96 per inch, but that isn't true.
For example, change the resolution of your screen and run the code
again!

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 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
Mahesh Patel

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.

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.

Finding the width and height of an image

Hi...
i have a path to an image "images/me.gif" and i'm trying to find its width and height.. am trying to use javax.swing.ImageIcon but it refuses to recognise the constructor with just the filename (string) parameter, and needs a URL to the file... anyone knows what i'm doing wrong??? is this the wrong class that i'm using...!??!?!?!?!?

String filename = "images/me.gif";
Image myImage = carregarImagem(filename);
System.out.println(myImage.getWidth(this));
System.out.println(myImage.getHeight(this));

Current page (not Document) width and height with JSX

Hi,
I am trying to create a script that saves every page of the document and add its width and height to the name.
So far I managed to get the dimensions of the document using:
app.activeDocument.pages.documentPreferences.pageWidth;
app.activeDocument.pages.documentPreferences.pageHeight;
That's ok when all the pages in the document have the same dimensions (Document Preferences).
However, when I use custom pages that does not work.
I tried the code below but does not work either.
for(i=0; i<nb;i++)
 app.activeDocument.pages[i].documentPreferences.pageWidth;
 app.activeDocument.pages[i].documentPreferences.pageHeight;
I have done some research and I don't seem to find any information regarding custom pages dimensions.
Can you please help with this?
Thanks in advance,
Isko

Main();
function Main() {
 var doc = app.activeDocument,
 pages = doc.pages,
 page, width, height;
 for (var i = 0; i < pages.length; i++) {
 page = pages[i];
 width = page.bounds[3] - page.bounds[1];
 height = page.bounds[2] - page.bounds[0];
 $.writeln("Page: " + page.name + " - " + "width = " + width + ", height = " + height);

Object width and height
