#[repr(C)]
pub struct charls_jpegls_pc_parameters {
    pub maximum_sample_value: i32,

}

Defines the JPEG-LS preset coding parameters as defined in ISO/IEC 14495-1, C.2.4.1.1. JPEG-LS defines a default set of parameters, but custom parameters can be used. When used these parameters are written into the encoded bit stream as they are needed for the decoding process.

Fields

maximum_sample_value: i32

Maximum possible value for any image sample in a scan. This must be greater than or equal to the actual maximum value for the components in a scan.

threshold1: i32

First quantization threshold value for the local gradients.

threshold2: i32

Second quantization threshold value for the local gradients.

threshold3: i32

Third quantization threshold value for the local gradients.

reset_value: i32

Value at which the counters A, B, and N are halved.
