Metadata for Radiance HDR image
Fields§
§width: u32
Width of decoded image. It could be either scanline length, or scanline count, depending on image orientation.
height: u32
Height of decoded image. It depends on orientation too.
orientation: ((i8, i8), (i8, i8))
Orientation matrix. For standard orientation it is ((1,0),(0,1)) - left to right, top to bottom. First pair tells how resulting pixel coordinates change along a scanline. Second pair tells how they change from one scanline to the next.
exposure: Option<f32>
Divide color values by exposure to get to get physical radiance in watts/steradian/m2
Image may not contain physical data, even if this field is set.
color_correction: Option<(f32, f32, f32)>
Divide color values by corresponding tuple member (r, g, b) to get to get physical radiance in watts/steradian/m2
Image may not contain physical data, even if this field is set.
pixel_aspect_ratio: Option<f32>
Pixel height divided by pixel width
custom_attributes: Vec<(String, String)>
All lines contained in image header are put here. Ordering of lines is preserved. Lines in the form “key=value” are represented as (“key”, “value”). All other lines are (“”, “line”)
