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

type int8 = (int, Bigarray.int8_unsigned_elt) Bigarray.kind
