Use after await initOpenCV(). See the initialization and named imports guide.

ARGUMENTSsrc, rdepth, alpha, beta

FUNCTIONgapi_convertTo

RETURN TYPEGMat

Call structure. A void return can still write to destination arguments. The parameter descriptions define inputs, outputs and ownership.

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:

m(x,y) = saturate \_ cast<rType>( \alpha (*this)(x,y) +  \beta )

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

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

gapi_convertTo(src: GMat, rdepth: number, alpha: number, beta: number): GMat;

3 available overloads

gapi_convertTo(src: GMat, rdepth: number): GMat;

gapi_convertTo(src: GMat, rdepth: number, alpha: number): GMat;

gapi_convertTo(src: GMat, rdepth: number, alpha: number, beta: number): GMat;

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.

Returns

The GMat result. Release returned native handles with using or delete(), including handles nested in results.
