Features

• Decoding images
  • PNGs (grayscale, RGB, indexed colors) with and without alpha channels
  • JPEGs (grayscale, RGB, CMYK)
  • TIFFs
• Decoding GIFs
• Rendering SVGs
• Rendering vector fonts
• Image manipulation functions (crop , rotate , composite, …)
• Color manipulation functions (invert , hueShift, …)
• Color information functions (averageColor , dominantColor, …)
• Encoding images as PNGs , JPEGs and GIFs
