Flash Island width and height - screen resolution

Hi,
I'm wondering if anybody knows a way to determine the screen resolution used in WDA? You might wonder why do we need screen resolution when you have 100% and flow layout.. well we're using a Flash Island frontend, and you are obligated to enter a height and width for the island. We'd like to support multiple resolutions for users and we could try to bind height and width to context attributes and set these in WWDOINIT perhaps if we'd know how to determine the resolution.
Thanks in advance,
Wouter

and you are obligated to enter a height and width for the island
I'm not sure that's completely true - I have an island that we set the height for - but the width as 100% - that seems to work just fine - albeit that the size is fixed from entry into the application - resizing the window does not resize the island.
I haven't wanted an island with 100% height - but are you sure this doesn't work?
if you watch the teched virtual session [CD203: Best Practices for Designing Web Dynpro ABAP User Interfaces |http://tinyurl.com/2dcp3fv] there is looooooooooong section in there where they go on and on about 100% rendering - it's pretty obvious - but worth repeating (at least it seems so in the session) 100% is only 100% of the container that the container is embedded within.
Have a go - I'm not 100% convinced you can't have a 100% island
Cheers,
Chris

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

Hello everyone
I need some help to create a fullcreen flash animation inside
dreamweaver.
What I did was to create a html file published in flash 100%
width and height.
It worked well on my explorer browser, but the size of the
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
This is the code on Dreamweaver html

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.

I need the exact width and height of the 12" Apple Lisa screen.

Does anyone have a bezel or a whole Lisa? I need the width and height, at their widest (center measurements) for the screen opening. Thanks very much!

You might check at ifixit.com.

Obtain width and height in device central?

I'm using device Central with Flash CS5.
How do I obtain the width and height of the device being simulated?
I need to write some special code to handle screen size in device central - as my application is already able to obtain the screen dimensions when run on a real device.

I need to know if this is possible, too!
Hopefully this is working somehow.
Thanks

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 do i get the max width and height?

Hey
I want to get the max width and height, so my desktoppanes size can be set automatically.
I know i should use getBounds but i cant find a concrete example on goole, on how to use it.
Can someone point me in the right direction, with an example?

Ok, assuming you want to get the screen resolution, i.e. 1024 x 768.
You will need these imports:
import java.awt.Dimension;
import java.awt.Toolkit;and this line of code:
Dimension myScreen = Toolkit.getDefaultToolkit().getScreenSize() ;You can now use myScreen.width and myScreen.height to access the height and width of your screen's resolution. (width = 1024, height = 768 in my case)
Hope this helps,
Stern

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);
 }

SWF loader need to load 100% width and height

Hi,
 I have using dashboard in my application.In which the flex pages are loaded using SWF loader. the swf is not loading 100% when i minimize the browser. actually its loading 100% when the browser is full screen mode. suppose the browser is opened in 75% the swf also gets loaded based on the browser size. but after maxmizing the browser the SWF its not expaned to the actuall size of the browser. could you anybody help me plz..?
Thanks & Regards
Muthu

Hi,
 I have used this code to load the swf in the main application:
<mx:Canvas id="dashCanvas" creationPolicy="all" cachePolicy="on" width="100%" backgroundColor="#FFFFFF" horizontalScrollPolicy="off" verticalScrollPolicy="off" >
 <mx:SWFLoader id="dashBoard" trustContent="true" width="100%" height="100%" scaleContent="true" autoLoad="true"
source="@Embed(source='../../../../assets/appl/dashboard/dashboard.swf')" />
</mx:Canvas>
And i have set width and height as 100% in <mx:Appilcation> .
Thanks and egards

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 :)

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
Narcís

Flex 4 Premium reference to the Stage issue! width and height seem to be switched??

So I am doing a very basic resize effect with a panel, but if I want it to fill the screen, I have to switch stage.stageWidth and stage.stageHeight. I have also traced them out and they come out as switched values. Anyone else having this issue?
protected function panel1_addedToStageHandler(event:Event):void
 trace(stage.stageWidth, " " , stage.stageHeight);

Hi,
You maybe running into some sort of layout constraint also it depends on how you are initiating the animation, if you are doing it on startup you need to wait for creationComplete to ensure all your dimensions have been calculated for the browser. You shouldn't need to use stage dimensions either. The following code resizes a panel to fill the browser. (note using top/left/bottom/right is a lot smoother than width and height).

How do i resize videos from my iPhone into iMovie so that they are the correct width and height as a standard youtube is ????

Hey guys i have recorded some videos on my iphone and i have synced them to my mac.
i would now like to edit them using imovie, the only problem i have is that when i open them in imovie, quicktime, vlc etc etc, they all playback at the same width and height as the iphone screen.
now is there any way using imovie that i would be able to resize the video to make it larger so that the video is the correct height and width of a video that you would see on youtube.
If this makes sense and if there is anyway of doing please let me know as i have tried looking for a shortcut or a plug in everywhere and i just cant seem to do it.
Thanks
Sean.

you probably recorded in 'portrait' orientation instead of videos standard 'landscape' ...
as my ex-wife always and approx. 75% of all 'phone movie maker' do ...
read in iMovies Help, how to use the CROP tool.

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.
