i want to read text in an image how to do that...
Thanks
What you’re asking about is called OCR, and it isn’t as simple as you might think. Luckily, there is at least one open-source effort to do it.
You need an OCR library, see this question for further information. For a more specific answer, you might want to post a more specific question.

The question I am asking is a little bit abstract, so I will try to make it more clear. There are websites where you sign up and get a signature in the format of an image. It has a general format, say a few boxes that are empty, and a logo in the middle. Now, say you gain the "Overachiever" badge, which looks like a pen. You signature is then updated, automatically, to include that pen badge in one of the blank boxes. I am completely clueless as to how to do this, and in what language to do this is, so can anyone help? I have been thinking about PHP as an option, but I do not know if that would work. Any suggestions?
You can do this with PHP (imagecreate) and for the updates in your images you can use cronjobs.
Is this for a forum? Depending on the platform, I know some hosts already have "addon's" that provide similar functionality to what you're after. (Karma addons etc.)
Maybe one of these will help? phpBB has some stuff like that.

If you can execute an external process, you can do this using Image Magick.
As like my other questions I tried to search for this. But I didn't get anything.
Maybe my path is wrong. Please direct me.
Here is my Question : I have a UITextView. In that I am going to add Numbers, Names and contacts.
I want to show each number separately as MessageComPoser did.
Does anybody know how to make this?
If my question is not worthy, give me the correct answer then downvote.
(For my questions somebody downvoted without even giving any answer!!)
There is no way to do this using apple's native framework, they didn't provided any controls for doing the same.
You can use the TTMssageRecipientField provided by Three20 framework.
I found the Answer. I don't want to use Three20 library since it is Very difficult to use in my project.
So i Found Awesome Link. That gives me the answer.
I used this Code It May HelpFull To many users, specially for those who Upvoted This question.
Exellent Code
I am working on an app with have requirement to give "Droste Effects" on image.i did search on Google more but not find programming solution for this effects.the effect example in there below.

http://www.pmavridis.com/iDroste/iDroste.html
Please provide me suggestion or any tutorials link. How i will do that task?.Thanks in advance.
The Droste effect is a trick made with some intense mathematics and a recursive function. Please read http://www.josleys.com/article_show.php?id=82. If you don't know about recursion please read up http://en.wikipedia.org/wiki/Recursion. Since your request is very specific I doubt there will be many people who happen to have a Droste effect code written in the iphone programming langauge, but the links above should help you understand the math behind creating your own. Good luck.
Is there any particular way to integrate Captch code validation in iPhone application?
is this possible to create captcha? (with or without web-service / any API)
If any kind of external library or any source is required to be imported, then also please let me know.
Any kind of link or source code is available then please suggest me.
Also suggest from where to start to do this, if possible.
Thanks in advance.
I know you probably don't want to hear this, but why do you need captcha on iPhone? It's completely useless since there are no bots or something.
But if you really need it then make some image with white background and then use this code
http://iphonesdksnippets.com/post/2009/05/05/Add-text-to-image-%28UIImage%29.aspx
to add text to the image... once you'll have this, then just check if the entered string is equal to the randomly generated one on the image and you are good to go.
I didn't find any libraries which could be used as a captcha, so I think this is probably the best solution right now.

I had asked a question earlier How to Searching String from PDF using iphone sdk?
I got a answer but that wasn't I was looking for. I am not sure to ask something similar as new question or not.
I am using ios4.2.
I am working on a application which display PDF. I am using Quartz 2D for that. I have gone through apple documentation and googleing of around 4 days I didn't find any thing that suits to me in this case. There are lots of question related to this and almost all answers are redirecting to either
Random Ideas or
FastKit.
Random Ideas don't explain how to highlight a text within the pdf. and FastKit has implementation but no Explaination too. I don't want to use fastkit because It shows its logo. can any one please give me any link which has some libraries or apis or any thing for highlighting text in PDF while I am using Quartz 2D.
Any help will be appreciated.
Thanks In Advance.
