- Encodes images supports all color modes (true color, grayscale and indexed) and transparency for all these color modes. The best color mode will be chosen automatically, based on the amount of used colors.
- R/W access to the image’s pixels.
- R/W access to all image metadata that is stored in chunks.
- Memory efficient (uses a Fixnum, i.e. 4 or 8 bytes of memory per pixel, depending on the hardware)
