Can I adjust pixel width and height in iPhoto?
I'm trying to find out if it's possible to adjust pixel width and height of a photo without cropping it. iPhoto Help was no help at all.
Thanks.

For uploading to a site this is the way to do it.
If you wanted to use in another application, you can drag and drop if it is supported, and then use that other application to resize. You can also set up a graphic application as an external editor.
I find it just as quick and easy to export to the desktop, then delete the photos on the desktop when I am done.

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!

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 :) -
How can I change the Width and Height of ROI ? Im attaching the VI it does the edge detection.. please help
Thankyou
Attachments:
edge.vi 95 KB
ROI.png 207 KBThe 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.

Help to edit width and height of menu?
http://www.ivoog.com/link4
How can I edit the width and height of this menu so the
background image fits? Please explain and give code if you can.
Thanks!
Here's the pictures for the menu:
http://www.pics.ivoog.com/boxs1.gif
http://www.pics.ivoog.com/boxs2.gifYour approach simply isn't going to work.
The background image is a fixed width. It will not shrink or
grow like the
text in front of it.
The background image is wider than the word "pie" but not as
wide as the
word "sigh".
So, if you add padding to the left and right of the link to
make the whole
background show behind "pie", the same padding is added to
"sigh". Now the
"sigh" link is much wider than the background image. Because
your
background image repeats, you see the left edge of the next
repeating one
behind sigh.
If you remove the padding to make it so you see just one
image behind
"sigh", now the padding around "pie" is too narrow to see the
whole
background.
You could try giving each link a class and having a separate
padding for
each word, but all that is pretty useless because different
people have
different text size settings in their browsers.
In some browsers, the words will be bigger than the
background image.
In others, the words will be small and you'll only see part
of the
background.
The free tutorial I sent you is just that, a tutorial.
You do the work, you have the copyright.
If you are not interested in that one, here's another idea.
You can use borders and simple background , like a gradient,
to make a tab
that looks just like your tab images and sizes along with
your text...no
matter how long the word is and no matter what size the text
is.
Here's the free tutorial.
You don't even have to do the whole thing, just the first
part where it
shows you how to make links that look like image buttons.

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.

Hiya.
I'm loading with SWFLoader games that where written using stage functions to get the width and height of the stage and to draw the game and calculate game movements accordinly. When I load a game using SWFLoader, the stage size changes from the stage size of the flash application that i loaded with SWFLoader to the stage size of my entire flex application with breaks the loaded flash application.
is there a way to override the stage related functions in the loaded flash application in order for them to return the proper value ?
if my flash application is width=50px height=50px and it's located at my flex stage at x=20px width=20px,
then the width and height of the stage of the flash application will return 70px.
is there a way to resolve that ?If an app has dependencies on stage size, it will not behave well as a
sub-app. -
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. -
Find new width and height of a rotated item
hi all,
I have an issue where I have a rectangle that I rotate and I need to know the new width and height of the bounding box of the rectangle when it has been rotated
example:
I have this rectangle shape
so its known width and height is 20pixels x 60pixels
now i rotate the rectangle by 90 degrees
so it looks like this
now its 60pixels x 20 pixels
but all i know is the width height is 20 x 60
how do I calculate the new width and height after rotation?
obviously a rotation of 45 degrees would mean the bounding box will not be 20 x 60 or 60 x 20 so I need to take that into consideration
thanksIf your shapes are not restricted to being rectangels, then the bounding box after rotation can't be calculate from simply the bounding box before rotation alone.
Simples counter-example:
The bounding box of those two shapes are equivalent:
{noformat}
and
{noformat}But after a 45 degree rotation, their bounding boxes are different.
For the exact way to calculate the bounding box for arbitrary shapes, you'll need to consult some geometry books (or wait and hope for a useful hint here, I can't give one). -
I cannot get DW8 to insert the width and height automatically
whern inserting an imge. Can anyone help me with it. TIAI have just discovered that if you do the insertion when Code
view and
Design view are 'in synch', i.e., neither the Property
inspector nor the CSS
panel have a "Refresh" button, the width and height will be
inserted in Code
view.

How to get width and height of a jpg file ?
Hello,
I'm trying to insert a jpg file in a blob field on my database. The problem is that I need to get the file width and height in pixels. My class does not have a graphic interface, it's a batch. Does anybody has an idea of how can I do that ?
tia.Write a jpeg decoder that can figure out how to determine the width/height of a jpeg file? Google it.
Or if you're really lazy, load each jpeg using the
Toolkit.loadImage( URL ) function and use getWidth/getHeight from there, but that's slow. -
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. -
Constraining mouse motion to specific distance (width and height)
Hi,
I want to constrain the mouse motion over a canvas by allowing it to move through specified distance (width and height).
How can i do this?
What does the translatePoint() in MouseEvent do? How do i use it?
Can someone help me with this?
Thanks
NiteenThe correct way with Pixel Bender 1.0 is indeed to pass in the width and height as parameters. There are no ramifications.

Losing width and height information of Image???
Hi,
I am losing the width and height information between converting an image to byte[] and then back to Image
public void testImageToBufferAndBack(Image takenImage){
BufferedImage bufimage = this.ImageToBufferedImage(takenImage);
System.out.println("buffimage"+bufimage.getWidth()+" "+bufimage.getHeight(null)); //works fine
ByteArrayOutputStream stream = new ByteArrayOutputStream();
try {
ImageIO.write(bufimage, "jpeg", stream);
catch (IOException ex) {
byte[] bytes = stream.toByteArray();
byte[] pictureBytes = bytes;
Image testImage = Toolkit.getDefaultToolkit().createImage(pictureBytes);;
System.out.println("tttttttteeeeeeeessssssttt "+testImage.getWidth(null)+" "+testImage.getHeight(null));
Output:
buffimage320 240
tttttttteeeeeeeessssssttt -1 -1
Could someone point me out my mistake please??Your mistake is not realizing that java.awt.Image loads images asynchronously. When Toolkit's
createImage method returns an Image, that image contains no pixel data -- as you've seen above, it doesn't
even know the size of the image! I knew this was the behaviour of the createImage method that took a URL,
but was surprised here that this is also the case with the version that takes a byte[], but undoubtably, that is
what is happening here. The way to fix this is always the same: use a MediaTracker, as my demo below
illustrates.
A couple points:
1. If you render your image in a custom component like this it will eventually appear:
g.drawImage(image, x, y, this); //for exampleThat's because Component's default behaviour as an ImageObserver (the reason for the final this)
is to continually repaint as more pixel data becomes available. This is not always the best solution -- what
if you need to know the image's dimension sooner rather than later?
2. ImageIcon can load an image for you, by using a MediaTracker behind the scenes:
Image image = ...
new ImageIcon(image);
//now image is loaded...Just be aware that if you use its constructors that don't take Image, but for example URLs
URL url = ...
Image image = new ImageIcon(url).getImage();Behind the scenes it's first getting the Image with Toolkit's getImage (not createImage). Toolkit's
getImage caches the image, which may not be what you want if you are processing many images --
why have the image loiter in memory if there is no advantage to that?

Possible to resize pic according to own width and height ratio?
Hi there
Usually when resizing (or exporting) a picture, iPhoto automatically chooses an appropriate combination of width and height for us. For example, if I wanted to reduce the width to 320 pixels, iPhoto automatically updates the height to 240, making the resized pic to be 320x240.
However, I need to resize a picture to become 300x300. How can I do that? When I type in 300 for width, iPhoto keeps automatically putting the height as 225, making the picture 300x225, but I need 300x300. Is there a way to manually choose how I want to resize the pic?
Thanks in advance.teriyip:
What you need to do before exporting is to crop to the size ratio, in this case square. Then you can put in 300 in one dimension field and the other will come in at 300 also. There's a square option in the Constrain menu.
Do you Twango?
TIP: For insurance against the iPhoto database corruption that many users have experienced I recommend making a backup copy of the Library6.iPhoto database file and keep it current. If problems crop up where iPhoto suddenly can't see any photos or thinks there are no photos in the library, replacing the working Library6.iPhoto file with the backup will often get the library back. By keeping it current I mean backup after each import and/or any serious editing or work on books, slideshows, calendars, cards, etc. That insures that if a problem pops up and you do need to replace the database file, you'll retain all those efforts. It doesn't take long to make the backup and it's good insurance.
