Enum openexr::header::LineOrder

#[repr(u32)]
pub enum LineOrder {
    INCREASING_Y,
    DECREASING_Y,
    RANDOM_Y,
}

Defines the line order of a scanline image.

For scanline images, only INCREASING_Y and DECREASING_Y are valid values:

• INCREASING_Y: scanline 0 is the first scanline in the file, and scanlines are written and read in that order.

• DECREASING_Y: scanline 0 is the last scanline in the file, and scanlines are written and read in that order.

In both cases, scanlines are written to and read from files in the order they are stored on disk, and any FrameBuffer you pass is interpretted that way as well.

For tiled images, all values are valid, but they have different meanings:

• INCREASING_Y: the tiles are stored in a particular order. See OpenEXR's [ImfTiledOutputFile.h] (https://github.com/openexr/openexr/blob/develop/OpenEXR/IlmImf/ImfTiledOutputFile.h) header for specifics.

• DECREASING_Y: the tiles are stored in a different particular order. See OpenEXR's [ImfTiledOutputFile.h] (https://github.com/openexr/openexr/blob/develop/OpenEXR/IlmImf/ImfTiledOutputFile.h) header for specifics.

• RANDOM_Y: the tiles are stored in the order written.

For tiled files, RANDOM_Y is probably a good choice, as it gives you control over the tile layout and doesn't require the OpenEXR library to do any buffering.
