🚀 Getting Started Issues
Q: Installation fails with module errors
A: Ensure you're using Go 1.18+ and run go mod tidy after installation.
Q: Fonts not loading properly
A: Check font file paths and ensure TTF/OTF files are accessible. Use absolute paths for reliability.
Q: Images appear blurry
A: Use high DPI settings with dc.SetDPI(144) for crisp output on high-resolution displays.
⚡ Performance Optimization
Q: Slow rendering performance
A: Enable SIMD optimizations with dc.SetSIMDEnabled(true) and use memory pooling.
Q: High memory usage
A: Enable memory pooling with dc.SetMemoryPooling(true) and clear caches periodically.
Q: Large file sizes
A: Adjust JPEG quality settings and use appropriate image formats (PNG for graphics, JPEG for photos).
