In my IOS App I want to Convert GIF to MOV/Video.
I don't Know Where To start.
I researched much and finally I know is I have to use ImageMagic API for this But don't Know How to Apply It.
Is there any other way except using ImageMagick???
Please Guide me In this Case That how to do so. Thanks in Advance.
You can Get sequence of images from that GIF. And then you need to convert those all into .png and then you can play that frames as mov.
That's the nice solution. For both steps libraries and tutorials are available

I'm trying to write an app that recognize a logo saved in app bundle and readed as UIImage. I have did a search before make this question, the only free solution seems to be OpenCv. I have tried it in a demo i had download from toptal_logo_detector . The demo works and i can find my logo everywhere i place it. Anyway the camera is very slow, too slow to use it in a real app. Maybe there's a way to optimize it, but my question is another.
I have to recognize a vector logo (always the same logo) centered in a white background ,something like this wifi logo:
My only solution is the complex OpenCV? There's a free and simpler way to achive the result: YES here there's your logo/No there isn't ?
I found this tutorial (with project download) that does what you want using OpenCV
How do I use animated PNG in Delphi?
If you are still searching for a solution then you can take a look
here where I've found this library that can solve your trouble.
With this complete library you can open APNG file then get number of frames etc...
I have got one image like this
to only black and white colored image.
And I come across this ImageMagick resource
Does this can be used to generate black and white image from the above given image?
Does it is good to use this one?
If it is good one then does there is any documentation or tutorial on "How to use?".
UPDATE
SO GOT THE BEST SOLUTION FROM #ale0xB's SUGGESTION.
No third party api is required for doing this as apple's COREIMAGE.FRAMEWORK is the best for doing what I want to do. It's filters are working like charm :)
Thanks for the suggestion :)
I use this image filter. And it is great in speed and provides great output :)
Why would you want to use imageMagick instead of the standard Core Image to produce black and White images? I haven't used it before, but I doubt it's gonna give a much better performance than the native framework when it's just about creating a filter.
Since iOS 6 you have it really easy, have a look: Core Image filters, specially to CIColorMonochrome, which is the one you may be interested in.
If you're playing with images in your app, this is definitely worth checking: Core Image Programming Guide
Does any one know of such library? I want to play with this functionality on an iPhone but dont want to write the code from scratch. PanoramaGL doesn't help as it only deals with displaying the panorama rather than building it.
Hope to hear from u soon

Depending on how complex a job you want to do the Opencv library has a panorama stitching module. Opencv now runs on iOS, see iPhone and OpenCV
see a Panoramic it opensource help you.
Not sure if this is helpful, but there is actually already a panoramic camera coded into iOS. you have to edit a plist file on a jailbroken device to enable it, though.
Is it possible to save a .fla file as an animated gif from an actionscripted animation? I know you can do it from a tweened animation quite easily, but haven't been able to figure out a way to do it from a scripted one.
I am not 100% sure I understand your question.
If you want to write an actionscript animation to a file from the Flash IDE, you can try quicktime(.mov) by choosing:
File > Export Movie and choosing QuickTime as the output format. This will allow you save the rendering of your actionscript to a file. A handy video by Lee Brimlow is available here.
I don't think it's possible to save a gif from the IDE for actionscript, but if GIF is a must you can try rendering with actionscript into an array of BitmapData objects that you would feed to a GIFEncoder.
Have a look at this fun and easy to use GIF Encoder by Thibault Imbert. I found it really easy to get started with.
Have fun!
