Function Documentation

void Resize	(	const QVImage< uChar > &	src,
		QVImage< uChar > &	dest,
		int	interpolation = IPPI_INTER_LINEAR
	)

Changes an image size.This function copies the content of the ROI in the source image, to the ROI of the destination image, adjusting it's original size to make it fit in the destination size It has the effect of resizing the original image, to fit the destination image, if both ROI's hold the whole of their respective images.

• IPPI_INTER_NN. Nearest neighbor interpolation
• IPPI_INTER_LINEAR. Linear interpolation
• IPPI_INTER_CUBIC. Cubic interpolation
• IPPI_INTER_SUPER. Supersampling interpolation, cannot be applied for image enlarging
• IPPI_INTER_LANCZOS. Interpolation with Lanczos window.
