Image writing

buffer simply is an alias to a bigarray with c_layout. Two kind of pixel buffers are manipulated:

  • int8 for images with 8-bit channels
  • float32 for images with floating point channels

Content of an image with c channels of width w and height h is represented as a contiguous sequence of items such that:

  • channels are interleaved
  • each pixel is made of c items
  • each line is made of w pixels
  • image is made of h lines
type 'kind buffer = ('a, 'b, Bigarray.c_layout) Bigarray.Array1.t constraint 'kind = ('a, 'b) Bigarray.kind
type float32 = (float, Bigarray.float32_elt) Bigarray.kind
