generators-watermark-engine

To add a watermark to images and video in Swift, you build a configurable rendering pipeline. This engine generates text, image logo, and attributed overlays using CoreGraphics, supporting configurable positioning, opacity, scale, and padding across iOS and macOS.

Yes, you can create a tiled watermark pattern for freemium protection in SwiftUI. The engine generates a tiled overlay option alongside a live SwiftUI preview, enabling rapid iteration of branding and attribution across your content.

Yes, the watermarking pipeline supports paywall-aware removal flows. It generates an optional configuration to hide watermarks automatically when a user has an active subscription or purchase, facilitating freemium app monetization.

The best way to scale watermarks based on image size in iOS is using size-based watermark scaling. The engine applies dynamic scaling logic during CoreGraphics rendering to ensure overlays match the target dimensions proportionally.

Yes, you need Swift 5.9 or later to use this CoreGraphics rendering pipeline for video overlays. The engine satisfies Swift 5.9+ requirements to ensure compatibility with modular content models and modern iOS/macOS targets.

Using a modular content model for text and image overlays in macOS separates rendering logic from data inputs. This approach manages text, image, and attributed watermarks distinctly, streamlining configuration for positioning, opacity, and padding.
