The document discusses vector and bitmap images on iOS, highlighting the benefits of vector images such as resolution independence and smaller app sizes. It also mentions various tools and frameworks for working with vector assets, including PaintCode, PDFImage, and SVGKit, noting their features and limitations. Ultimately, it emphasizes the importance of choosing the right implementation details for asset management in app development.
Vector Assets on iOS
- 1. Vector Assets on iOS
- 2. Bitmap Images • Coloured squares in a grid make up an image • Pixels • Fixed size, determined by number of pixels • Resolution dependent • Scaling is undesirable
- 4. Vector Images • Mathematical shapes • Resolution independent • Scales beautifully
- 6. Vector Images on iOS • Promises smaller app size • Streamlined workflow for designers • More flexible • Not currently popular
- 7. Technologies • Asset Catalogs • Open-source frameworks • PaintCode
- 8. Asset Catalogs • Supports Vector assets in PDF format • Generates bitmaps at build time • Still copies the PDFs into your app
- 9. SVGKit • Open-source iOS framework • SVG format • Too buggy
- 10. PDFImage • Open-source iOS framework • Same format as Asset Catalog • Renders at run-time • No unnecessary assets • Supports animation
- 11. PaintCode $99.99 • Commercial graphics tool and code generator • Supports many formats, ton of extra features • Renders at run-time • Real-time code generation. No assets at all? • Supports animation, dynamic colours, dynamic shapes, parametric drawing via variables and expressions
- 12. Vector Assets on iOS • Implementation details are important. • Asset Catalog probably not what you want. • PDFImage works as advertised, but is 3rd party. • PaintCode is awesome, worth it if you go beyond just plain vector images.
