Struct EfViewOrigin 

#[repr(C)]
pub struct EfViewOrigin {
    pub parent_width: u64,
    pub parent_height: u64,
    pub parent_row_stride: u64,
    pub x: u64,
    pub y: u64,
    pub has_origin: u32,
}

Parent-region snapshot for a tensor that is a view/batch sub-region.

The scalar block ef_tensor_view_origin fills, the same shape as ef_tensor_plane and ef_tensor_image_desc_view – one library reading a tensor it did not mint. has_origin is a presence flag rather than a sentinel value because every field is a legitimate 0 for a view pinned at the parent’s top-left corner; the other fields are meaningful only when it is non-zero. Mirrors edgefirst_tensor::ViewOrigin.

Fields

parent_width: u64

Logical width of the root parent image, in pixels.

parent_height: u64

Logical height of the root parent image, in pixels.

parent_row_stride: u64

The parent’s row stride in bytes.

x: u64

This view’s top-left x origin within the root parent, in pixels.

y: u64

This view’s top-left y origin within the root parent, in pixels.

has_origin: u32

Non-zero when this tensor is a view/batch sub-region; 0 for a whole tensor, in which case the other fields are all zero and unused.
