API Reference
The following list provides an overview of the key classes and methods available in PHImageKit:
- PHImageKit
The main class of the library, responsible for image processing operations. Provides methods for resizing, cropping, filtering, and applying overlays to images. - PHImageProcessor
A helper class that performs the actual image processing operations. Users can create instances of this class to enable more control over the image manipulation process. - PHImageFilter
A collection of pre-built image filters that can be applied to images. Includes filters for adjusting brightness, contrast, saturation, and more. - PHImageOverlay
Allows users to add custom overlays, such as text or graphics, to images. Provides methods for positioning, resizing, and adjusting opacity of the overlay elements.
Usage Examples
In this section, we will explore a few usage examples to showcase the capabilities of PHImageKit.
Example 1: Resizing an Image
To resize an image using PHImageKit, you can use the following code snippet:
let resizableImage = PHImageKit.resizeImage(image, targetSize: CGSize(width: 200, height: 200))
The above code resizes the image
to a target size of 200×200 pixels.
Example 2: Applying a Filter
To apply a filter to an image, use the applyFilter(_:)
method. Below is an example of using the PHImageFilter.sepia
filter:
let filteredImage = PHImageKit.applyFilter(image, filter: PHImageFilter.sepia)
By calling the above code, the image
will have the Sepia filter applied.
Example 3: Adding an Overlay
Adding an overlay to an image is straightforward with PHImageKit. The following code snippet demonstrates how to add a text overlay:
let overlay = PHImageOverlay(text: "Sample Overlay", font: UIFont.systemFont(ofSize: 24), color: .white)
let imageWithOverlay = PHImageKit.addOverlay(image, overlay: overlay, position: CGPoint(x: 20, y: 20))
This code adds a white text overlay saying “Sample Overlay” to the top-left corner of the image
.
Conclusion
Congratulations! You are now equipped with the knowledge to get started with PHImageKit, an incredibly powerful library for image processing on iOS. By following the installation instructions, referring to the API reference, and exploring the provided usage examples, you will be able to leverage PHImageKit’s features effectively in your projects. Happy coding!
