Vector / Raster Images

• SVG file format

Color

• RGB values in [0,1]

  black = (0,0,0), white = (1,1,1), red = (1,0,0) etc → forms a color space!

• LDR storage

  8 bits / color channel (0 to 255) → most used, sufficient if it is implemented right! BUT if we modify images, we would want more precision hence, 16bits.

  16 bits / color channel (0 to 65536)

• HDR storage

  16-bit float (half)

  32-bit float

Raster Image Storage

• Interleaved Storage

  

• Separate Channels
