Image Filtering

So it seems to be a lot of image filtering collections popping up lately to add to NYXImagesKit née NYXImagesUtilities we mentioned before, let’s list them here for handy reference shall we?

XBImageFilters: OpenGL ES 2-based image filters for iOS

XBImageFilters allows you to obtain filtered versions of any image or from the camera in realtime. It uses OpenGL ES 2 to filter the images through fragment shaders you write yourself so you can filter your images in whatever way you want and it is super fast…

Introducing the GPUImage framework

I’d like to introduce a new open source framework that I’ve written, called GPUImage. The GPUImage framework is a BSD-licensed iOS library (for which the source code can be found on Github) that lets you apply GPU-accelerated filters and other effects to images, live camera video, and movies. In comparison to Core Image (part of iOS 5.0), GPUImage allows you to write your own custom filters, supports deployment to iOS 4.0, and has a slightly simpler interface….

Native iOS Image Filter Library Based On Filtrr.JS For Easy Photo Filters

Based on a popular open source javascript project also known as Filtrr this library provides many different filters that can be easily customized with methods allowing for easy changing of the brightness, contrast, saturation and tint of the image. Also provided are basic scaling and cropping methods to make things easier…

And to finish off, this isn’t a filter exactly but it probably complements nicely what you’re filtering:

Library For Creating Framed, Shadowed, Stacked Images Automatically For A Real Photo Look

…  To give an image that “real photo” look that you’ve likely seen in many different apps (and all over the web too).

This library allows you to create a similar effect, and also allows you to stack the images. This is typically done with Photoshop or some other image editor.

What I like about this library is that it automatically adjusts the frame size, and aspect ratio so you can just shove in your images, and it will automatically adjust the size of the frame, and shadow size…

That should give you a big leg up on just about any image manipulation needs!
