Is there a possibility to identify if an image (coming out of the photo library in iOS) is an animated GIF or just a normal photo? I want to show also GIFs inside my app (built with appcelerator titanium), but I need to identify if it's an animated picture first. That's related to the fact that the normal ImageView is not able to show animated GIFs, as far as I know - but there are tweaks to show a GIF, nevertheless I need to know that it has to be rendered in this special way instead of using a normal imageView.
Can I read this information somehow out of the image metadata?
Check this repository. There is a module for Appcelerator.

I am currently creating a web app that will allow users to upload their highlights / clips from Overwatch and I wanted to use JavaScript to detect what character they were playing as.
I currently have it taking a still from the video that they upload, but wanted to use JavaScript to detect the image at the bottom left of the screen and get a result for which character it is:
I am unaware of any libraries that can do this while not over complicating my needs. Furthermore if I was to use an AI library such as tensor (which im not even sure if it would work), would I be able to use the training data if I bundled it as an app for the app store?
If the image in the bottom left is the same, you can accomplish this using canvas.
You would need to chop the whole image down to just the avatar, and then compare the avatar to ones on file.
The comparison would require the base64 of the image, and compare those bases. If they are the same, voila!
I would like to make an image viewer that can display multiple images in a document format. Basically my web application server right now is sending me an array of base64 png files that I need to display in a viewer that looks like a document. A good example for my requirements would be the following picture:
Also I should be able to animate the pages by rotating them, moving the page from one place to another or deleting a page by either clicking on the thumbnail or scrolling through the page and performing the necessary action. Currently my frontend imageviewer looks like this:
Which is mostly for testing purpose but I would prefer it looks more like the first example Image. Is there any library that can help me with this or any suggestion on how to start about it. Any advice would be grateful!.
Thank you!
I have been going through a few SO questions and getting bits and pieces from it, but the solution is not fully apparent. What I have is a Django web server and in my model for posts I have an ImageField. I have then created my form and that renders fine.
I can use the input tag just fine, and it will upload to the server and location saves to the database. The problem comes when I take an image on an iOS device in portrait and view it on another platform e.g. Android, Desktop, the image will be rotated.
Now I have found out that when you take an image on iOS it will keep the resolution as landscape and put into the EXIF data the orientation of the image to make it portrait.
So finally my question is, what is the best approach to this issue. The options I have seen as are:
In the webpage where the upload occurs, transform the image and reset the orientation then upload to the server.
Upload as is, and in my view do the transform/reset before the save.
Again upload as is, and I render the image in the view detail post and fix it there.
I will also at some point also be creating some thumbnails and smaller instances of the image. Only thing my javascript skills are not the greatest!
Thanks
For working with images python has some good packages.
Pillow :
You can use it from this link:
https://pillow.readthedocs.io/en/4.1.x/
or Easy thumbnails for Django (it is easy version and based on Pillow)
https://pypi.python.org/pypi/easy-thumbnails
I want an image slider similar to what is shown in the link below.
http://blog.dreamcss.com/wp-content/uploads/example/
I have customized the script to my needs but I'm not able to find a way to change the image transition effect, rather than moving image from right to left I want image to dissolve & show other image that would make this script really code. I am open to new jQuery based Image Effect Slider/Gallery With similar look. This is the client's request so the design will remain same.
I would appreciate if i can change the image effect or if some one can provide me link for similar image slider.
I have to use this with ASP.Net and possible modify this script to integrated with database using c#
Thanks in Advance..
I use Flex slider http://flex.madebymufffin.com/ , it is very customisable and lightweight and should do what you want
Take a look at these Javascript Image and Photo Galleries. I would recommend using the existing APIs provided by these script libraries using JSON to pass data to the client from the server as opposed to modifying the script -- keeps it simple.
Alternatively, you could look at some of the stuff on CodePlex: Image Gallery if you wanted a server control to use with your solution.
how can I change the way an image loads on a web page? I presume using javascript to do this. I'm looking for a way to have the picture load at a lower resolution and then get "sharper". As appose to loading downward, if that makes sense. Facebook does this with their "theater" picture pop-up window.
This is actually due to the way that the image is encoded, namely images that are interlaced will have this effect.

Check to see if your image editing utility has this feature, applications such as photoshop definitely will but something as simple as paint won't.
Sounds to me a lot like progressive loading in jpg images. That's something you have to adjust while creating the image. I'm only familiar with the gimp, there you have to check a checkbox while exporting to jpg. Check out this screenshot.
Another way to achieve this is to initially point the images on the webpage to smaller images and then do some stuff with some jQuery plugin. I'm not sure right now but I think there was one called jQuery.lazyload or sth. like that.
Hope it helps you!
To do this you don't need javascript. It is actually part of how you saved your image. You should make your image with progressive option. It adds a little weight on the image, but it will show parts of image as it is loading.
To do this on Photoshop:
Open your images file
Choose File
Choose Save for Web... option.
On the opened Dialog select jpg
On the upper right corner there are few options. Check 'Progressive' option
You are done!
Now replace your image and all the browser will show that image as they are loading it.
