How search for a string or image inside an image?

Here's what I want to do:
1. The user has an image that they don't know if they or someone else applied some modification to (either drawing some text on it or an image)
2. The program can look and see if he text is drawn at a specific size, font, style, location, angle and alpha on the image (or an image done much the same way on top)
How would I do this? Is it possible to look for that pattern without the original, unmarked image? (So you couldn't compare it and see if the pixels in that location differ the right way)
Is this even possible in Java? Where do i start?

>
The second way (with no original image to compare to) might be impossible.>No, no. That is what the scrying is for, just scan (or grab an image via a webcam) the crystal ball for an image to work with, then proceed with the strategy you outlined for comparing 2 images. ;-)
As far as image filters that compare one image with another, you might first look to a video processing tool such as AviSynth. It is a script based video editing tool (that can work equally well with static images), that provides a whole heap of image operations that allow easy comparison of images. I mention it because I am guessing you will see an image operation that works for your purposes, and can then research the filter type for how to go about implementing it in Java.
For (vague) example, one image subtracts the other, with a 'minimum threshold' set to account for the slight changes that might occur between PNG and JPEG - if there are no changes, the resulting image should be 'black'.

How do i search for a string in a txt file using java??

How do i search for a string in a txt file using java??
could you please help thanks
J

Regular expressinos work just fine, especially when
searching for patterns. But they seem to be impying
it's a specific group of characters they're looking
for, and indexOf() is much faster than a regex.If he's reading from a file, the I/O time will likely swamp any performance hit that regex introduces. I think contains() (or indexOf() if he's not on 5.0 yet) is preferable to regex just because it's simpler. (And in the case of contains(), the name makes for a very clear, direct mapping between your intent and the code that realizes it.)

How to search for a string in ALL Function Modules source code

Hello,
I want to search for the string "HELLO" in all FUNCTION MODULES source code(FM, no reports/programs).
Is this possible? How?

How can I search for a string like a partial IP address in the global search

When searching for a string like "10.255." the global search finds messages containing "255" or "10" and both.
This happens no matter whether quotation is used or not.
When quotation is used it probably will match on the given order as well, but beeing in the timezone '+0100' the string "10" is always found first (in the email headers...).
Is there a way to tell the global search not to use '.' or any other character as whitespace?

Searching for a string in an excel file and return true if found.

How can I search for a string in an excel file and return true if found, its location and also a value.

The problem with searching an excel file is that it contains a header. It would be easiest if you just read the file into a LabVIEW array and search the array. This way you can also get the index and the value of the location.

Search for broken links to images

Is there an efficient way to search for broken links to
images?

Hi there
I'm not sure if you are meaning to ask about links inside
topics that point to images that you are popping up or linking to
outright or if instead, you mean that some of the images that are
supposed to be displayed inside topics are maybe missing and you
wish to know about them.
One easy way to spot a missing image reference is by using
the Project Manager. Not sure if you are using RoboHelp 7, 8 or
older here, but if on 7 or 8 look in the Project Manager pod.
Otherwise it will be found on the left panel of the application.
Expand the Images pseudo folder and quickly scan the list of images
and expand sub folders inside. Any missing image should be listed
with a red x to indicate the status. You may then examine the image
properties to see which topic(s) is/are still referencing it.
Cheers... Rick

Search for a String in a list of files

Could anyone please send me a java sample code which searches for a string from a list of files and returns me the filename and the line in which the Search String was found ?
Thanks in advance
RR

Simple solution would be -
1. Traverse a directory for each file.
2. Read each file using Buffered Reader.
3. Use readLine() method to read a line.
4. Use String.indexOf to see if the data which you are looking for is there in the line or not.
5. If its there then store the line number and file name.
6. When the loop will end you will have list of file name and line number where the data which you are looking for is present.

Search for a String within a document (Word, txt, doc) using JSP, JAVA

Hi
I have created a little application that uses combination of JSP and HTML. Users of this application can upload documents which are then stored on the server. I need to develop functionality where I can allows users to search for a string within a document. More precisely, user would type in some string in a text box and application will search all uploaded documents for that string and return the downloadable links to those documents that contains that string. I have never done this before. I was wondering if someone could get me started on this or point me to some thread where this idea is already discussed. Any Jave code exists for searching through documents??
Thanks for your help

Search for a string in SAP Script

Hello Experts,
Is there a way to search for a string in all Z SAP scripts, like ABAP source scan?
Regards,
Hari.

Try using function module "READ_FORM" (you will have to write a simple z-program to find all SAPscripts in your system then use this function module to search the SAPScript Forms for a particular string).
All you have to do is supply the "FORM" name and it will return all of the Pages, Paragraphs, and Texts etc....
More specifically, try looping at the "FORM_LINES" internal table result and you will see the SAPScript text there....
Have fun !

Is Safari Find function flexible? (Search for inner strings of characters?)

I'm running 10.6.8 with Safari Version 5.1.7 (6534.57.2). I see that when you search a web page using the Safari Find function, you can only search for the beginnings of words, not for character strings within the words. Is it possible to expand the Find function's capability to search for inner strings of characters?

use command F or the edit menus to make the page search box visible - click the magnify/arrow icon at the left side of it - choose "contains" or "starts with".

How to search for particular string in array?

I am struggling to figure out how to search array contents for a string and then delete the entry from the array if it is found.
The code for a program that allows the user to enter up to 20 inventory items (tools) is posted below; I apologize in advance for it as I am also not having much success grasping the concept of OOP and I am certain it is does not conform although it all compiles.
Anyway, if you can provide some assistance as to how to go about searching the array I would be most grateful. Many thanks in advance..

Ok, so you have an array of Strings. And if the string you are searching for is in the array, you need to remove it from the array.
Is that right?
Can you use an ArrayList<String> instead of a String[ ]?
To find it, you would just do:
for (String item : myArray){
   if (item.equals(searchString){
      // remove the element. Not trivial for arrays, very easy for ArrayList
}Heck, with an arraylist you might be able to do the following:
arrayList.remove(arrayList.indexOf(searchString));[edit]
the above assumes you are using 1.5
uses generics and for each loop
[edit2]
and kinda won't work it you have to use an array since you will need the array index to be able to remove it. See the previous post for that, then set the value in that array index to null.

How to: Search for a string in entire movie project?

I used a copyrighted name a few different places as I was creating a very long and complex game. I have since removed it from the game where it was previously showing up but when I search the exe, it's still there in a few places. Is there a way to search the entire movie project and all content, all scripts for a particular string? For instance "Microsoft".
If so, I cannot find a way and could use some direction, even if it's an xtra I need to install that adds this capability.
Thanks!!!!!

Scripts are easy. You open any script window and hit Ctrl + F and enter your search term in the Find box, ensuring the "All Casts" radio button is checked.
For text and field members you'll need to write a script that does the search for you. If you were clearer about what you want to happen when you find your search term in a text member then someon could help you with how to perform this. I know there is already code posted to the forum somewhere about how to examine every member of every castLib checking the member type - which would be a very good place to start.

How to search for a string in a DefaultListModel

I have a list of names stored in a DefaultListModel and would like to know how i can search for a particular name
i assume i would have to use the method below but not sure of how to implement it
so basically i would have a texfield where a user can type in a name to find in the list
public int indexOf(Object elem)
Searches for the first occurence of the given argument.
Parameters:
elem - an object.
or i might be wrong
Any ideas of how to write this mechanism
Can anyone please help on this

The DefaultListModel uses a Collection of some sort (Vector at present) to store data. You can get this data in two ways:
   DefaultListModel model = (DefaultListModel)list.getModel();
    Enumeration e = model.elements();
    while(e.hasMoreElements()) {
      if (e.nextElement().equals(elem)) return;
    }or
    Object[] array = model.toArray();
    for (int i = 0; i < array.length; i++) {
      if (array.equals(elem)) return;

How to search for exact string?

Is there any way to search for the text string exactly as I enter it? Like 'exact search' in the OSS notes?
For example, I'm trying to find the forum posts regarding the Excel 2007 file format XLSX. By XLSX the search finds hundreds of entries, but most of them are not even close. For example, this was one of the top results: /thread/1078918 [original link is broken]
Why is it getting picked up when 'xlsx' doesn't even appear there? We are frequently complaining about the users who don't use search before posting, but, frankly, if it works like this, I can't blame them...

"Why is it getting picked up"
I regularly use this to (re)find threads where I remembered a specific comment or even spelling mistake.
Perhaps a better option in your case would be to use an AND between individual terms.
I generally tend to edit the search string parameters directly, as it seems to cache previous results and do a search within a search. That might be an option for you as well though.

How can i search for multiple file names (images) in bridge?

Hello everyone!
Does anyone know how to search for multiple file names in bridge?
That is to copy & paste something like this: _MG_2152, _MG_2177, _MG_2194, _MG_2195, _MG_2202, _MG_2212, _MG_2219, _MG_2261, _MG_2362, _MG_2401
Not using several criterias in the search box that is. That takes too long.
