Struct BlobInfo

pub struct BlobInfo {
    pub version: u32,
    pub data_type: u32,
    pub depth: u32,
    pub width: u32,
    pub height: u32,
    pub bands: u32,
    pub valid_pixel_count: u32,
    pub blob_size: u32,
    pub masks: u32,
    pub uses_nodata: u32,
}

Metadata extracted from a LERC blob using lerc_getBlobInfo.

This structure provides information about the dimensions, data type, and encoding details of the compressed raster data, without fully decoding the blob.

Fields

version: u32

Codec version used to create the blob.

data_type: u32

Encoded data type (see LERC C API DataType enum).

depth: u32

Number of values per pixel (aka depth or dimensionality).

width: u32

Width of the image in pixels (columns).

height: u32

Height of the image in pixels (rows).

bands: u32

Number of bands (layers) per pixel.

valid_pixel_count: u32

Number of valid pixels in the first band (others may differ if multiple masks).

blob_size: u32

Size of the compressed blob in bytes.

masks: u32

Number of validity masks:

• 0: all pixels valid
• 1: same mask for all bands
• nBands: per-band masks

uses_nodata: u32

Indicates how many bands use a no-data value (only applies if depth > 1).
