This library can write colored images which use floating point values into
OpenEXR (v2) high-dynamic-range file format.
Supported features:
scanline format
compression (ZIPS, ZIP)
pixel format (RGB float32)
Usage
Modify project’s stack.yaml by adding path to openexr-write package.
packages:
- '.'
- path/openexr-write
An image can be written by calling writeFile function. For example,
following code stores a compressed image consisting of one red pixel.
module Main where
import qualified Data.Vector as V
import qualified Graphics.OpenEXR as EXR
main :: IO ()
main = do
let image = EXR.ImageRGBF 1 1 (V.fromList [EXR.PixelRGBF 1.0 0.0 0.0])
EXR.writeFile "image.exr" image EXR.ZipCompression
