How can I comparing image at a specific display size?

Respected sir/madam,
I want to compare two images with their pixel values.But actually images are around 600MB size.
Is it possible to check images with some temporary width,height like 100*100 or etc.
Regards,
M.Suresh Kumar

As you ask the question right now, you are talking about scaling down the images to 100*100 which would be "not a good idea" - I assume that's not what is on your mind at all.
Are you perhaps thinking about comparing the images not as a whole in one go, but in stead cutting them up on smaller pieces of 100*100 pixels and comparing those?

How can i compare the contents of two folders ?

how can i compare the contents of two folders and find out which files are in one but not in the other?? Knowing how to do this would be the best thing ever, especially when dealing with a large number of files. Often, for instance, I'm dealing with a large number of images, processing them, and saving the retouched ones to a new folder, and need to check that they are all there. If there are say three files missing in the second folder (out of say a hundred in total) being able to automate the process of elimination would be very useful. Please help!!!

I really wish I knew the answer to this. I work between two macs, a G5 and MacBook Pro when I'm on the go. Each time I move from one to the other I have to copy all my files to the computer I'm going to work on, so I end up with the same files being duplicated. It's not a problem if it's not much data but in my case the it can be to 30GB, mostly graphics files, photoshop, motion, final cut pro, etc.
There's has got to be a way automator can make a comparison between two folders to sort out what's changed and what's remained the same. It would be nice also if this feature could be done globally on the hard disk using spotlight's technology to stop files being duplicated in places you didn't even know about and taking up valuable disk space. I'm not sure how this could be done.
Any bright ideas Apple?

How can I import image sequences into Fireworks???

I quote:
Not specifically "import" but you can open a series of images as an animation. This will place each image in its own state, suitable for creating an animation.
Choose File > Open

Mysql datetime datatype, from that datetime how can i compar only time part

Hello i have database table in mysql, there is Datetime datatype column, from that datetime how can i compare only time part .....??
Thanks in advance...

Note you can't simply just compare time via equality however.
Timestamp resolution is to the second or even milli-second. No user wants to match a time to an exact millisecond.
What they want is something like a match by hour - for example returning the number of transactions that happened from 1pm to 2pm. Even that isn't completely correct because then you need to consider whether 1pm and/or 2pm is inclusive or exclusive. Normally one end will be inclusive and the other exclusive.
So first you need to define what the period is.
Then construct the range.
Then pass the range and, as already mentioned, use specific functions to handle the extraction of the time.

How can I assign image file name from Main() class

I am trying to create library class which will be accessed and used by different applications (with different image files to be assigned). So, what image file to call should be determined by and in the Main class.
Here is the Main class
import org.me.lib.MyJNIWindowClass;
public class Main {
public Main() {
public static void main(String[] args) {
MyJNIWindowClass mw = new MyJNIWindowClass();
mw.s = "clock.gif";
And here is the library class
package org.me.lib;
public class MyJNIWindowClass {
public String s;
ImageIcon image = new ImageIcon("C:/Documents and Settings/Administrator/Desktop/" + s);
public MyJNIWindowClass() {
JLabel jl = new JLabel(image);
JFrame jf = new JFrame();
jf.add(jl);
jf.setVisible(true);
jf.pack();
I do understand that when I am making reference from main() method to MyJNIWindowClass() s first initialized to null and that is why clock could not be seen but how can I assign image file name from Main() class for library class without creating reference to Main() from MyJNIWindowClass()? As I said, I want this library class being accessed from different applications (means different Main() classes).
Thank you.

Your problem is one of timing. Consider this simple example.
public class Example {
    public String s;
    private String message = "Hello, " + s;
    public String toString() {
        return message;
    public static void main(String[] args) {
        Example ex = new Example();
        ex.s = "world";
        System.out.println(ex.toString());
}When this code is executed, the following happens in order:
1. new Example() is executed, causing an object to constructed. In particular:
2. field s is given value null (since no value is explicitly assigned.
3. field message is given value "Hello, null"
4. Back in method main, field s is now given value "world", but that
doesn't change message.
5. Finally, "Hello, null" is output.
The following fixes the above example:
public class Example {
    private String message;
    public Example(String name) {
        message = "Hello, " + name;
    public String toString() {
        return message;
    public static void main(String[] args) {
        Example ex = new Example("world");
        System.out.println(ex.toString());
}

How can I compare the actual and expected values in Unit testing when they are XML files?

I have created a unit test for a method in VS 2008. My expected value and actual value are XMLs. Therefore though the output is same as I expect it gives an error as I am doing string comparison now. How can I compare these 2 XMLs in expected output and
actual output format in Unit Testing?
mayooran99

In unit test, when you want to validate XML files, you feed them into the class / struct that you want to feed the XML into and compare the values there (You don't just feed it in XMLReader and feed it line by line, right? But if it really is, that's how
you should also test it in unit tests).
In short, how you'd use the XML in your code, that's how you should test it in unit test.

My Itunes Library and iPhone have fallen out of sync on music over the yearsare - how can I compare my itunes library with my Iphone to see what songs are missing from my library so I can then bring my Library up to date

Hello Solid Buck,
Thank you so much for providing the details about the duplicate song issue you are experiencing. It sounds like you would like to remove the duplicate songs that will not play on your iPhone, but when you connect it to iTunes, iTunes only shows you one copy of the song on your iPhone.
In this situation, I recommend deleting the individual songs that do not play directly from your iPhone. I found the steps to do this on page 61 of the iPhone User Guide (http://manuals.info.apple.com/en_US/iphone_user_guide.pdf):
Delete a song from iPhone: In Songs, swipe the song, then tap Delete.
Thank you for using Apple Support Communities.
Best,
Sheila M.

How can I use Automator to extract specific Data from the text files and either create a new text file or excel file with the info? I have looked all over but can't find a solution. If anyone could please help I would be eternally grateful!!! If there is another, better solution than automator, please let me know!
Example of File Contents:

Is this possible? I can't imagine having to go through each and every file one by one. Please help!!!

You may try the following AppleScript script. It will ask you to choose a root folder where to start searching for *.map files and then create a CSV file named "out.csv" on desktop which you may import to Excel.
set f to (choose folder with prompt "Choose the root folder to start searching")'s POSIX path
if f ends with "/" then set f to f's text 1 thru -2
do shell script "/usr/bin/perl -CSDA -w <<'EOF' - " & f's quoted form & " > ~/Desktop/out.csv
use strict;
use open IN => ':crlf';
chdir $ARGV[0] or die qq($!);
local $/ = qq(\\0);
my @ff = map {chomp; $_} qx(find . -type f -iname '*.map' -print0);
local $/ = qq(\\n);

Photoshop is not a format. It's an application.
What you are looking at are not true JPEGs, just iPhoto's "tease" representations of the hidden images it swallowed, as explained above.

In iPhoto, how can I export images with the metadata - including the title and caption information - intact as part of the image?
