cvResize...

Resize

Resizes image

void cvResize( const CvArr* src, CvArr* dst, int interpolation=CV_INTER_LINEAR );

src
Source image.
dst
Destination image.
interpolation
Interpolation method:

* CV_INTER_NN - nearest-neigbor interpolation,
* CV_INTER_LINEAR - bilinear interpolation (used by default)
* CV_INTER_AREA - resampling using pixel area relation. It is preferred method for image decimation that gives moire-free results. In case of zooming it is similar to CV_INTER_NN method.
* CV_INTER_CUBIC - bicubic interpolation.

The function cvResize resizes image src so that it fits exactly to dst. If ROI is set, the function consideres the ROI as supported as usual.
