Declaration
function resize(dst: TIEVisionImage; interpolation: TIEVisionInterpolation = ievLINEAR): TIEVisionImage; overload; safecall;
function resize(newWidth: int32_t; newHeight: int32_t; interpolation: TIEVisionInterpolation = ievLINEAR): TIEVisionImage; overload; safecall;
Description
Resizes (resamples) current image to the specified size, using an interpolation filter.
First overload stores the resized image in the specified destination object. Uses destination size as resize parameters. Source image remains untouched. Returns the destination object.
Second overload resizes the image inplace, returning itself.
Note: You can use
assignIEVisionImage to reflect this methods changes in the associated bitmap
| Parameter | Description |
| dst | Container for the resized image |
| interpolation | Interpolation filter |
| newWidth | New image width. If less than 0, this is auto-calculated |
| newHeight | New image height. If less than 0, this is auto-calculated |
Examples
// resizes image1 to 1000x1000, using CUBIC interpolation
image1.resize(1000, 1000, ievCUBIC);
// resizes image1 to the size of image2 (1000x1000)
image2.create(1000, 1000, ievUINT8, 3);
image1.resize(image2, ievCUBIC);
// Double size of image
ImageEnView1.IO.LoadFromFile( 'D:\im300a.jpg' );
DestIEViewer1.IEBitmap.Allocate( ImageEnView1.IEBitmap.Width * 2, ImageEnView1.IEBitmap.Height * 2 );
ImageEnView1.IEBitmap.GetIEVisionImage().resize( DestIEViewer1.IEBitmap.GetIEVisionImage(), ievCUBIC );
DestIEViewer1.Update();
