Help needed : getting the size of an image

Seems that my first post didn't work.. so i try another time.
I'd like to get the size (width and height) of an image file, just using the path of that file.
Does anyone knows if there is an existing class that can allow me to, or does someone knows the way i should work on it
Thanks in advance

In java.awt.Image there are getWidth() and getHeight()

Help with reducing the size of an image but keeping the quality

Hello,
I am wondering how do I resize an image but keep the quality. I am creating a folder design for work and I want to include 6 images on the back each of 156px x 118px.
The images I have are slightly different in size but for example sake one of the images that I have is 225px x 158px. The quality is very poor when I reduce the size.
I have tried changing the ppi to 72 and to 300, I have also tried resizing all in one go and in a number of goes and I have tried the bicubic sharpener but I have just had no luck with it.
I am wondering if anyone can help with this,
Thanks
Tracy

Hi Tracy,
A couple of questions:
I am creating a folder design for work...
So this is printed? How large? Pixels are not a unit-of-measure for print.
If for print, you are looking at ppi of 300 or higher AT PRINT SIZE.
So, say you want a 3in x 4in picture. That would mean your original would have to be at least 900px X 1200px. (ie 300ppi x width, 300 ppi x height)
If your original files are not at least that resolution.. . it is hard to add quality after the fact. Unless your are working with vector art.
I have tried changing the ppi to 72 and to 300, I have also tried resizing all in one go
Be sure to do that on copies of original. Keep in mind the PPI number by itself is completely meaningless. It only has use in describing a to be printed image when combined with the print size.

How to get the size of an image?

try something like:
// in case 'this' is a JComponent or something similar:
MediaTracker mt = new MediaTracker(this);
mt.addImage(myImg1, 1);
mt.addImage(myImg2, 2);
while (!(mt.checkAll(true))) {
try {
Thread.sleep(10);
} catch (InterruptedException iex) { }
// all loadedThis would load all images registered with the MediaTracker but also blocks execution of your program. You might want to start a different thread for this.

Getting the size of a jpeg image

Hello,
I'm looking for a way to get the size (height and width in
pixel) of a jpeg file before actually loading the file.
Is it possible ?
Thanx.
Vincent

This is a flaw in Pages IMHO.
As for many things the information and manipulating the properties is oblique to say the least.
You have to do what you have done or do some calculations based on size, and known resolution.
A way around might be to tag the image in the name with the actual pixel size.
I work from my images marked in folders as vLoRes, LoRes, MedRes, HiRes, vHiRes and uHiRes.
Given a basic requirement of a bare minimum 100 pixels/cm (roughly 254dpi) for commercial reproduction the images will cover (with bleed):
vLoRes = A7
LoRes = A6
MedRes = A5
HiRes = A4
vHiRes = A3
uHiRes = beyond A3
But then I happen to be very systematic in the way I work. It is a useful skill I have taught in my studios. Unfortunately many designers, and users in general, are sloppy and short sighted.

This may depend on your chosen encoding options for the Mails (MIME vs. Base64 or similar) and/or the mails being reduced in size and sliced up server side. Apple (and Google) do stuff like recompressing images when viewing mails on mobile devices from an Apple ID or Gmail account... You have to turn it off in their web frontends....

How to set the size of an image

My following code shows the original size of an image. Now i want to see different size of this image. How is this possible? I know control the size of this image after saving this image
in a file. but i want to control the size of this image without saving this image in a file? IS it possible ? Is there anybody can help me?

hi,
I have a database which contain an image. now i
want to retrieve this image & want to show this
image in my jsp page as user's defined size. I have
following code. My following code shows the original
size of an image. Now i want to see different size
of this image. How is this possible? I know control
the size of this image after saving this image
n a file. but i want to control the size of this
image without saving this image in a file? IS it
possible ? Is there anybody can help me?This has nothing to do with JDBC; you can only store and retrieve the image you have and there's no image manipulation functions in JDBC (nor should there be).
I can see 2 options:
1) serve the image file as is, but in the jsp that writes the html that contains the "<img>" tag that gets it, use the "height" and/or the "width" to scale the suppied image to presentation size you want.
2) find some image manipulation code that will convert the image into the size you want
Option 1 will work well if the problem you have is merely refining the image size for presentation. Option 2 is your only coice if it's the image files size itself you really want to change, not just it's appearance on a page.

How to decrease the size of an image (CS5)?

I need help with how to reduce the size of an image to fit various smaller sizes. E.g. 135 x 380mm, 254 x254mm etc mounted/matted. Therefore, the image must be made smaller than these sizes without losing quality and any part of the image. I am unable to crop to achieve these sizes since I need the full image. These photos were taken by using a Canon D450 camera and in both RAW & JPEG.
Your help is much appreciated.

You may want to use Image > Image size... and dial in the sizes you want.
Set your units to mm in the dialog. Turn off resample and you can adjust the final print size.
What I am showing you is called "scaling", changing the print size without throwing out pixels as resample would do. Your image is intact. This is from CS6, but it should be about the same in CS5.

How can I get the resolution of an image file in JSP?

how can I get the resolution of an image file like jpg,gif,png in JSP ?

Hii,
If by the resolution, u mean size..this is how u can come to know....
String add = "path/to/some.jpeg";
javax.swing.ImageIcon chain = new javax.swing.ImageIcon(add);
int height = chain.getIconHeight();
int width = chain.getIconWidth();
Hope that helps.

When I try to print a photo downloaded from Facebook in iPhoto, I can't get the size I specify to print correctly. Example: 5x7 prints smaller than 5x7. What do I do to solve this problem?

When I try to print a photo downloaded from Facebook in iPhoto, I can't get the size I specify to print correctly. Example: 5x7 prints smaller than 5x7. What do I do to solve this problem?

Those pixel dimemsions have aspect ratios that are not the same as a 5 x7 print:
1360 x 1360 = 1.0
790 x 640 = 1.23
2048 x 1366 = 1.5
An 7 x 5 image = 1.4.
So you'll need to crop the images to 5 x 7 before printing. The first two images are a little light in the pixels to produce a high resolution 5 x 7 print.

here i need the size of noextensionarray array List
I've used method get_size() for the calculation of niextensionarray List in above class which is marked as bold.
since I've allocate memory to the array above the hdrFileFileter() so now the array list is showing the zero size of arraylist.
PLS. help me to get the size of arraylist noextensionarray.

Hello all,
the code contain two classes
1. hdrFileFilter: used to filter out files containing the extension .hdr and those files that haVE the same name as the header file has but with no extension.
files that have no extension are stored in the arraylist "noextensionarray".
2. Reference Class: this class is using the files that are stroed in the array List "Noextensionarray" one by one. for this I required the size of arraylist. I'm using the size of array through function get_size it gives the size=0;this function is defined in class hdrfilefilter.although it is diaplaying the name which are stored in arraylist on commad prompt.
I appricate all the comments given regarding the solution of the problem.

How to get the size of the cuurrent illustration

Sorry, I made a mistake before this one. The questios is this: can anybody tell me how can I get the size of the current illustration, (as oposed to the page size) in points. Something like 120 points wide and 87 points High?. What function do I need to call?

From AI Function reference (included with CS2 SDK):
AIDocumentSetup setup;

I'm making a widget that gets the filename of an image on a website and it changes the value of some parts of the widget if the filename has a certain name. The only problem is that I don't know how to get the name of this image in the widget. Could somebody please help me?

If I understand well, I think that the XMLHttpRequest object may help you. Please check the following link:

Also, if you can program in Perl (or some other scripting language), you can use an external script to read the filename and send it to your Widget.
