APNGKit Files

Add

• Add maxRenderSize parameter to all APNGImage initializers. When set, the compositing canvas and cached frames are downsampled to fit within the given size, significantly reducing memory usage for oversized APNGs. The image's logical size and layout behavior are unchanged. #151 @plateaukao #152 @onevcat

Fix

• Integralize the render-space rectangle in APNGDecoder.renderRect(_:) to prevent fractional coordinates from causing CGImage.cropping(to:) to return nil during .previous disposal, and to avoid 1px gaps between partial-frame regions. #152
• Fix the Demo app's Frames overlay to use proportional coordinates, so the frame-region highlight stays correctly aligned when maxRenderSize downsampling is active. #152

Note

• Update CI to macos-26 runner, actions v4, Ruby 3.3, and Xcode 26.5 toolchain. #152
