Hello I have added the whole library to my project with this line "">" the problem is that is a heavy library and the page takes long time to initiate. I just need two features which are math.std (standard deviation) and math.median (average) so docent make scene to upload the whole thing.
I dont know how to make the customization to use those features, I will be very to receive some help
Maybe this page in the docs helps?

I'm taking a beginning mobile development class, and my professor wants me to jump right in and help him with an app of his written in Objective-C, and I have 3 months. I have taken a few other CS classes so far, but no next to nothing about mobile app development.
This app is basically a songbook that holds many PDF files of music scores. The first (of multiple things) that he wants me to add is the ability for a user to annotate the music score with highlighter, pen, and eraser. Since there are many music scores, I would need to have the app save these annotations for each score, and allow editing by the user later if needed (i.e. allow the user to go back and erase stuff and add more annotations to a given score).
I'm in the planning phase and I'm trying to figure out the best way to do this. I was thinking of having the annotations occur on a second view layer, and then saving that layer as an image so that it can be overlaid back onto the music notes sheet at any time (for the user to view). My concern is, would the user be able to re-annotate this layer once it has been saved as an image (i.e. erase and add more annotations, then save it again)?
Or what's the best way to go about this? I would really appreciate any advice because I am in over my head!
Well This is very broad question to answer it but let me help you with some links and you will need to go through that like.
It will help you to start your requirements into app.
There are many 3rd party frameworks are there for PDF annotations:
PSPDFKit (Paid)
FastPDFKit
Poppler (OpenSource)
There are some SO Questions links which also helps you for PDF annotation
Add Annotation to PDF
Annotation on an PDF
Programmatically add annotations on PDF
Some Github Links
LazyPDF
Note: LazyPDFKit - (No longer maintained - Use the source code to fix
the bugs)
Hope this will helps you in your research.
I've created a core mechanic of my game and want to create a level editor for it. my game is not a tile-based one, so my needs are quite specific. Game is written using Swift and Cocos2d-swift, but i dont think i can figure something out with Sprite Builder.
What you can advice me? Can I for example create a level editor with c# and then use it from swift code?
And what data structure is the best?
I mean is it possible to serialize classes on desktop Swift application and then just load them on ios from file or I'll need to use json/xml?
It might be an old question but I ended up with using a .Net powered solution. I choosed as It has all controls that you need for creating a rich user interface and also, it has a lot of built-in and third party solutions for serializing levels in any way you want. And the c# syntax is very similar to the Swift one.
The only problem is that you might run windows to work with it.
My game in development also needed a non-tile level editor. A few months ago I took some time to make my choice.
Since my project still uses cocos2d 2.x, I don't use the whole new 3.x and SB system. After some investigation I found out that it would be too time consuming to adjust my whole project to the new system and adjusting SB to my needs, mainly because my game engine has been in development for quite some time and is close to finished. Further more, I couldn't find the right information to actually make it work for my game (it needed some odd level architecture I guess).
Finally, I didn't find any other good alternative so I decided to create my own level editor. In this way I had full control and I knew exactly how everything worked which was a huge advantage for me.
Right now my level editor has been finished for some time and works like a charm. I still think in my situation I made the right choice. Also because I learned a lot this way, building everything from the ground up. Having said that, for my next game I will probably go with the main stream and use SB from the start. Also for you I advice you to still check out SB and take some time for it before making an alternative choice...
I'll explain how I did mine. Disclaimer: it has some oddity's which only worked in my situation, but hopefully it helps a bit with choosing your own way to go, that's the goal I'm aiming at...
I used:
max/msp
Although it's developed to make music and audio based software, I used max/msp because it's very easy and fast for creating visual and interface based software as well.
More importend: I happened to be very experienced in it, which shortened the development time tremendously.
javascript
Inside the max/msp patch is a javascript file running. This file is like a bridge between the interface and the visual representation of the level being edited, and the database in which the level
is saved in. 70% of the editor development went into this file I think.
sqlite
All the data is written in a sqlite database. Again, this has been mainly the choice because it saved a great amount of development time in my case. I could have used xml files for instance, but my game was already using a sqlite database and because of this I felt comfortable using it, I had no experience in xml. Also all the code was already in place for a big part, which speeded up the whole proces a lot.
I'm very happy with the end result. It does everything I need, it's easy too use and since I made everything myself from the ground up I know exactly how every works.
Good luck with you choices.
I was wondering so long that how can people analyze the trait of each file extension (of course open it in notepad is not readable)
For example, I want to write a program that can read everything from .fla file like timeline, movie clips, position of each MCs or all the motion tween values. And get the image embeded in it. (I'm planning to use flash as IDE for another project.)
(The reason that I tried to read proprietary format is I want to utilize their awesome editor. What I actually want to do is, I want to make an iOS game with cocos2d. There is a code to move things around in cocos2d but there is no decent editor. So I'd like to use Flash as an editor, then convert the motion to objective-C cocos2D code by reading the .fla file.)
If you would like to be able to import timeline animation from flash into cocos2d, this tool might help. More information in this thread.
The grapefrukt-exporter might also help as it can export keyframe data, and various other formats for animation.
Instead of creating the tool yourself, it might be much easier (and time saving) to use one of these and integrate it into your workflow :)
Finally, if none of the above works, how about just exporting the flash animation as an animated GIF or a movie file?
Im assuming you want to write a decompiler, this is possible and there are several available on the internet, price varies.
It is not possible for flash to achieve this, Most programs, software are built on a native language such as C, Native meaning it can independly run in its own with out initially setting up an invironment to support it.
Flash is not independent enough to be available to have this much power.
Try looking at c++ or C# as this would be possible, also these languages are a lot more powerful.
There seems to be a lot of conflicting information out there. It might be that support has increased recently, or changes to adobe.com/air have made some information difficult to find - but I can't track down a definitive list of things to avoid.
I know that actionscript won't run in loaded SWFs, I know that some people say that filters and blendmodes and halo components won't work. I've also read many posts saying they will (at least that blendmodes will, and that halo will run, but slowly so still use spark)
I have a large amount of AS3 code to plan for upgrading to work on iOS, but at the moment I have no idea what things will break (or what things will break when those things have been fixed!)
Is there a list of unsupported APIs, or iOS dos and don'ts?
Thanks
:S
First, yes. Externally loaded SWF's will not run. You can however embed SWF's/SWC's into your project and include them inside of your package.
As far as Flex components, stay away from Halo. You should use Flex 4.6 and stick to components with mobile skins. I recommend downloading Tour de Flex http://www.adobe.com/devnet/flex/tourdeflex.html to get an idea of whats available.
As far as blend modes go, I'm not really sure. I haven't used them in mobile yet. However filters are supported but they are expensive. For drop shadows on rectangles there is something called RectangularDropShadow. This is actually a component and therefor less expensive. However it can only be used on rectangular groups.
You should have access all of the AIR API's. You will however be restricted when using some of File related classes since I don't believe you can leave your Appliaction Storage Directory.
One big performance tip I can give is to use AS3 over MXML whenever possible, ESPECIALLY when creating item renderers. Use BitmapImage over Image whenever possible, again especially in item renderers. Use cacheAsBitmap whenever you have images that don't change often. And stay away from any Flex component that doesn't have a mobile skin.

I need a help to develop a small application on Augmented Reality.I have spend almost a week trying but with no proper solution.Tried some sample code but still not successful.
I have seen many videos and want to develop something like that.
for example my code should detect only square or any particular shape.And then after detecting the square and another Image should appear on the screen.
Please help me out.
This stuff is hard, but most new cool things are until they are no longer cool or new.
You can play with AR Toolkit until you are familiar with the functionality and then attempt to dive into the setting and mess with those, then maybe look at the source.
