Function convert_to

pub fn convert_to(
    src: &impl GMatTraitConst,
    rdepth: i32,
    alpha: f64,
    beta: f64,
) -> Result<GMat>

Converts a matrix to another data depth with optional scaling.

The method converts source pixel values to the target data depth. saturate_cast<> is applied at the end to avoid possible overflows:

Output matrix must be of the same size as input one.

Note: Function textual ID is “org.opencv.core.transform.convertTo”

Parameters

• src: input matrix to be converted from.
• rdepth: desired output matrix depth or, rather, the depth since the number of channels are the same as the input has; if rdepth is negative, the output matrix will have the same depth as the input.
• alpha: optional scale factor.
• beta: optional delta added to the scaled values.

C++ default parameters

• alpha: 1
• beta: 0
