Image width and height

I cannot get DW8 to insert the width and height automatically
whern inserting an imge. Can anyone help me with it. TIA

I 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 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();?

The crawled property of Image width and height - is there a differnce when the image is png format?

Hi,
We are indexing file share with images and get the properties of Image Width, Image Height, Image Size (we show it as refiners in SharePoint after make it managed properties). Somehow when the picture is png format - we see only Size but not height and width.
Is that any setting that should be done in the file share (when i select an image in the windows explorer window i can see all its properties, and it seems that png files do expose the width and height properties
keren tsur

Hi Keren,
According to your description, my understanding is that when you tried to crawl file share with images, the ows_ImageWidth and ows_ImageHeight crawled property for PNG file could not be generated.
For your issue, I can reproduce your issue in my SharePoint 2013 environment. For a workaround, you can upload the PNG images into SharePoint images Library and they would work fine.

Get image width and height?

In loading an image using the File Browse capability, is there any way to obtain the height and width of the image being loaded? I want to save that along with the MIME type and file name.

Hello,
Take a look at the ORDImage object type, which you can use to obtain the properties of the image -
http://download.oracle.com/docs/cd/B28359_01/appdev.111/b28414/ch_imgref.htm
You can do much more than just accessing the properties too, such as rescaling the image, greyscaling, making a thumbnail etc.
Scott Spendolini did a good blog post on this a while back -

(by the way, doesn't this highlight a short-coming of the new forum points system? Scott does a nice long detailed blog post...I just link to it and hopefully get the points ;).

[iPhone] image width and height was exchanged after load to CALayer

I want to put an image into a CALayer's sublayer, like this:
*CALayer *parent = [CALayer layer];*
*CALayer *child = [CALayer layer];*
*[parent addSublayer:child];*
*UIImage *image = [UIImage imageWithContentsOfFile:imagePaht];*
*NSLog(@"%f-%f", image.size.width, image.size.height);*
*child.contents = [image CGImage];*
I have five images in my app to display, their sizes are (3648, 2048),(3648, 2048),(3648, 2048),(2048, 3648),(2048, 3648), but when the images are displayed, I found that the last two images were rotate 90 degree. anyone has such problem?

No - not quite the same - but about the same on iPhone 4.
My app uses ImagePicker to let the user select an image from the album or the camera roll. I picked an image (that was shot in landscape mode) from the album. The image picker showed it in portrait mode so, it was smaller in size. But when the app showed the image in different view, it was shown in original size in portrait mode - as if the image was zoomed in!
This does not happen on iPhone 3GS, though.
Any ideas?

Adobe Fireworks CS5: A way to change an existing slideshow export image width and height?

I have an existing slide show with 8 albums with numerous images in each. They have all been carefully labeled and sorted and placed.
The export image size was set, at one time, to 800 x 600 and everything displayed splendedly..
After just adding another album, all of a sudden, the images are displayed as 320 x 240. I have not idea why this is and I can't seem to figure out how to change this without creating the entire slideshow from scratch because the fields for the image size are greyed out...
Can someone please let me know where I would find this knowledge? I'm not very well versed in webdesign and only have this site and gallery using dreamwaever and fireworks through brute force...
Very appreciative of any help!

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);
 }

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));

* @return A imagem requisitada ou null caso n�o haja tal imagem na url do applet

Get image properties (width and height)

Hi there,
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.

Resize and crop images to a specific width and height

Hi,
I want to convert images to thumbnails with a 'standard' format - I need all images to have the same width and height.
So I need to resize and then crop the images. Is this possibe with JAI? Are there other libraries which can do this better?
I've read about ImageMagick - are the Java interfaces to ImageMagick good?

Images with width and height

There is a way to insert an image inside of the html code
with width and height already? I mean, now, if I want to insert an
image at the code, goes only <img src="images/test.gif" /> I
d like that if I insert an image it goes as: <img
src="images/canto_topo.gif" width="8" height="29" />
is possible in dreamwaver to do that?
Thanks!
Vismona

If you insert the image using the "Insert Image" function, DW
will
automatically insert the width and height.
Or, if you'd rather insert them the way you are, in the
Property Inspector
on the far left, click the dimensions next to the Image
field, and DW will
automatically add (or correct) the width and height.
Hope that helps,

Draw rotated image to given width and height

Problem, if an image where width and height aren't equal is rotated and drawn again, the image is not drawn (stretched) to the full width.
Below is an example to illustrate my problem. The top image is stretched to the full width, the other aint.
Example picture: http://www.google.nl/intl/nl_nl/images/logo.gif
What am I doing wrong??

Get width and height of a dynamically loaded image once it's done loading?!

hello : :
well... i'm taking my first shots at flex after programming
in flash for a year now. it's been fun and i've been picking up on
things pretty well (or so i think), but i come across something
today that i used to be able to do in my as2 programming and don't
know how to do in as3...
in flex, i'm loading an image into an image control (by using
"myImgControl.load(urlString)"). i have a "complete" parameter on
the image control that calls a function just fine after the image
is loaded, but if i try and check the hight and width of the loaded
image once it loads, it comes back as zero. how can i get the
height and width of the image after it's loaded?!
in flash/as2 i used to do this little trick/work-around i
found in a forum (kirupa.com, i think) to find out the width and
height once the loaded image listener checked the loading process
and came back "complete"... in the code below, "imgLoader" is the
movieClip the image was loaded using
imgLoaderListener.loadClip(urlString, imgLoader).
quote:
iTot = imgLoader.getBytesTotal();
iLoad = imgLoader.getBytesLoaded();
if (iLoad == iTot && iTot > 4) {
imgH = imgLoader._height;
imgW = imgLoader._width;
that all make sense?!
basically, it's as simple as this: i need to find something
similar to the above for as3 that will tell me the width and height
of a dynamically loaded image after it's done loading...
so there ya have it. i appreciate any help any of you can
throw my way! thank you so much for even reading this!

I assume you have probably already figured this out, but just
in case, there should be an event to listen for after which you can
get the height and width information successfully. I can't remember
the exact name, however. Experiment and see which one works
time-wise.

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.

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?

        ImageIO.write(original, "jpeg", out);
        byte[] bytes = out.toByteArray();
        Image image = Toolkit.getDefaultToolkit().createImage(bytes);
        displayDimensions("created image", image);
        loadImage(image, new Label()); //any component will do
        displayDimensions("loaded image", image);

            throw new RuntimeException("Unexpected", e);
        if (mt.isErrorID(0))
            throw new IOException("Error during image loading");
    static void displayDimensions(String msg, Image image) {
        System.out.println(msg + ", w=" + image.getWidth(null) + ", h=" + image.getHeight(null));
}Output:
original buffered image, w=235, h=240
created image, w=-1, h=-1
loaded image, w=235, h=240
