Function:Resize

Re-sizes input image to fit into the output image size.

Function

CuviStatus resize(const CuviImage& src, CuviImage& dst, CuviInterpolationType inter = CUVI_INTER_LINEAR, const CuviStream& stream = CuviStream());

Parameters

Name	Type	Description
src	const CuviImage&	Input Image
dst	CuviImage&	Output Image
inter	CuviInterpolationType	Type of interpolation to use for re-sizing. Supports: CUVI_INTER_NN CUVI_INTER_LINEAR CUVI_INTER_CUBIC
stream	const CuviStream&	GPU stream ID for execution

Image Type Support

Input	Output
8uC1	8uC1

Samples

Input Image (Width = W, Height = H)	Resized Image (width =0.78625*W, height= 0.78625*H)
Input Image (Width = W, Height = H)	Resized Image (width = 1.2*W, height= 1.75*H)

Example

CuviImage gimg = cuvi::io::loadImage(path); const Cuvi32f xScale = 0.5f, yScale = 0.7f; const Cuvi32s newWidth = static_cast<Cuvi32s>(gimg.width() * xScale); const Cuvi32s newHeight = static_cast<Cuvi32s>(gimg.height() * yScale); CuviImage gout(newWidth,newHeight,gimg.type()); //Re-sizing input image to fit output container using bicubic interpolation cuvi::geometryTransforms::resize(gimg,gout, CUVI_INTER_CUBIC);
