Getting started

• Type.t: Defines the type of an image: u8, u16, f32, f64, i32 or i64

• Color.t: Defines the color of an image: gray, rgb, rgba, xyz and yuv

  • It's possible to extend the color type by implementing COLOR
• Image.t: Image type
• Kernel.t: Convolution kernels
• Transform.t: Image transformations

• Expr.t: Expression combinator

  • Building blocks for image processing filters

• Filter.t: Executable image filter

  • Makes Expr.t executable

There is a corresponding file for each of these types in src/.
