Struct EncodeRoiRegion 

pub struct EncodeRoiRegion {
    pub component: u16,
    pub x: u32,
    pub y: u32,
    pub width: u32,
    pub height: u32,
    pub shift: u8,
}

Rectangular region-of-interest request for JPEG 2000 maxshift encoding.

The rectangle is expressed in full-resolution reference-grid pixels. For sampled components, the encoder maps the rectangle to that component’s SIZ grid before selecting wavelet coefficients. All regions for the same component must use the same non-zero shift, because JPEG 2000 RGN stores one maxshift value per component.

Fields

component: u16

Component index to which the ROI applies.

x: u32

Left edge in reference-grid pixels.

y: u32

Top edge in reference-grid pixels.

width: u32

Width in reference-grid pixels.

height: u32

Height in reference-grid pixels.

shift: u8

Maxshift value to write in the component’s RGN marker.
