Module Stb_image_writeSource

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

Sourcetype float32 = (float, Stdlib.Bigarray.float32_elt) Stdlib.Bigarray.kind
