I want to use GtkImageView in my application, but i can't find some examples of code with using gtkimageview anywhere. Where can i see the sample?
Thank you.
There's no GtjImageView in GTK+, I guess you meant GtkIconView. There are two examples for the latter in gtk-demo program that comes with GTK+ itself.

I am new to iOS development and apologies for a basic question. I am trying to convert an image to grayscaled and threshold it using openCV in iOS. So far, I have imported and setup the framework on xcode. What I am trying to do now is to implement the following features:

at 0:24 and 0:53
I tried to follow the tutorial which points to the above youtube video :
http://docs.opencv.org/doc/tutorials/ios/image_manipulation/image_manipulation.html
and wasn't sure where to paste the above code and in which file?
Many thanks.
Kind Regards.
These are helper methods and best written in a separate file. Quite simply,
http://answers.oreilly.com/topic/631-how-to-get-c-and-objective-c-to-play-nicely-in-xcode/
Put all that image manipulation code in say ImageManipulationHelper.mm and create a header file for the same
Create a nice little category for UIImage.
http://developer.apple.com/library/mac/#documentation/Cocoa/Conceptual/ProgrammingWithObjectiveC/CustomizingExistingClasses/CustomizingExistingClasses.html
which can call these methods in turn to create any image manipulation you might want.
Easy does it. And yeah, read up a bit more on using C++ in objectiveC, if you get into trouble and also about categories. They are some of the niftier features of objectivec
I achieved the same,using the help of this awesome link
Let me know if you need any further help.
Cheers!!
Edit :
Check this out ImageFiltering
i was wondering about where Zends functionality comes from when inside of a controller i call
$this->getRequest()->isPost()
It works, but i do not find where this "isPost()" function comes from.
I just noticed it because i don't have intellisense for that.
Question is:
Is this merely some fallback function that "newbie users" use apart from a better alternative?
Or is it perfectly valid using it?
Thanks :)
It is the official way to go, you can use it. Check the source code of Zend_Controller_Request_Http::isPost() to see what it really is doing, if you'd like :)
I just wrote my first nodejs program using the node-mongodb-native driver. I used the documentation code from the github page, i.e.:
var mongodb = require("mongodb"),
mongoserver = new mongodb.Server('localhost', 6574),
dbConnector = new mongodb.Db('test', mongoserver);
dbConnector.open(function(err, db){
if(err)
console.log('oh shit! connector.open error!');
else{
...
However, upon looking at some example code on the github page, I discovered that the set up code looks very different from what I used. Does anybody know if there's any real difference between the different methods? I'm completely new to all this stuff and can't really tell if there's any reason to use one over the other. The code I wrote seems to run fine, but if the creator of the driver is using different code, I figured it would be worth checking if there are any reasons for that.
Thanks in advance for any replies!

Hi I'm the creator and no there is no particular reason you can't use your style. As when it comes to docs I usually tell people to start with the integration tests as there are many examples on how to do stuff. Unfortunately due to having a fulltime job the docs are not kept up to date at the pace I would like to.
I'm hoping to do something with that come late september but right now I'm trying to just get the driver up to the expected features of mongodb including making it work with 1.9.X and higher.
I'll accept any docs pull requests happily as the more the community help me the more it helps itself :)
i am trying to use the goTo function to switch between different divs.
but in the function goTo(id,animation)
it is not going to that id.
Can anyone please help me with this problem.
Thanks,
Devan
This is difficult to diagnose without looking at your code. I have a few ideas, but it would be best if you were to share the problematic section of your code for others to investigate.
A few questions/ideas:
1) Check to ensure you have not used the same div ID more than once.
2) Have you been able to successfully use the goTo function at all?
3) Can you create a basic HTML page that uses this function successfully?
4) What version of jQTouch are you using? Does the goTo function work once, and then freeze every time afterwards? I reported a bug regarding this behavior a while ago. Not sure if it's been resolved yet, but you could see if an older version of jQTouch might help.
Again, without examples of your code... I'm taking wild guesses. Consider sharing the problematic section and someone might be able to pinpoint the issue.
Don't put animation, without animation worked for me...
eg..
jQT.goTo('#rest');
is there any complete source code available for developing a image editing,paintng application in iphone???if anyone knows plese help me
thankzz

Berkeley had a hw assignment. Students submitted them via wiki so maybe look at those?

There is an application named TouchPainter and its source code is available. It contains drawing, color blending, Undo/Redo (Amazing..!!), Save/Open drawings..
Note : It may require very deep level knowledge of Objective C. The whole application's source code is explained in this book "Apress.Pro.Objective-C.Design.Patterns.for.iOS.Mar.2010" available and source code is also available here :

I hope it will be helpful to you.. :) Good luck..
