Everyone wants filters. But if you want to add filters to your app today, you have to research image processing libraries, design filters in Photoshop, attempt to translate them into code and build a filter picker and other controls from scratch.

The FilterKit Picker

• Here’s how it works:

• Add the FilterKit library to your app.

• Pass an image from the iOS camera or photo library to the Filter Picker View Controller, where users can browse and apply filters.

• Get back the processed image.

• You can customize FilterKit by:

• Choosing from a thumbnail-style or our original carousel-style filter picker (shown here).

• Choosing which filters to offer from our collection of presets, or find and share more filters online.

The FilterKit Builder

• Designing multi-step filters can be tedious. Image processing frameworks like GPUImage let you adjust parameters one step at a time, but the best filters involve multiple steps.

• The FilterKit Builder offers a visual interface for creating multi-step filter “recipes.”

• You can visually adjust each parameter to your liking, then export your filter recipe as a new class that can be added to your app.

The FilterKit Gallery

• You can also share your filter recipes with others by uploading them to the FilterKit GitHub repository and adding a link and thumbnail to the FilterKit Gallery.

• The FilterKit Gallery makes it easy to find and share great filters, so no developer has to create “that toy camera effect” again from scratch ever again.
