TIEVisionImage.max

Declaration

procedure max(source1: TIEVisionImage; source2: TIEVisionImage); overload; safecall;
procedure max(source1: TIEVisionImage; source2: Double); overload; safecall;

Description

Calculate the per-element maximum of two images or an image and a scalar.
Note:
◼The source images must be the same size and color depth
◼You should allocate the destination image to the same size as the source images

ImageEnView1.IO.LoadFromFile( 'D:\im300a.jpg' );
ImageEnView2.IO.LoadFromFile( 'D:\im300b.jpg' );
DestIEViewer1.IEBitmap.Allocate( ImageEnView1.IEBitmap.Width, ImageEnView1.IEBitmap.Height );  // Allocate the destination image
DestIEViewer1.IEBitmap.GetIEVisionImage().max( ImageEnView1.IEBitmap.GetIEVisionImage(), ImageEnView2.IEBitmap.GetIEVisionImage() );
DestIEViewer1.Update();

// ALTERNATIVELY...
DestIEViewer1.IO.LoadFromFile( 'D:\im300a.jpg' );
ImageEnView2.IO.LoadFromFile( 'D:\im300b.jpg' );
DestIEViewer1.IEBitmap.GetIEVisionImage().max( DestIEViewer1.IEBitmap.GetIEVisionImage(), ImageEnView2.IEBitmap.GetIEVisionImage() );
DestIEViewer1.Update();


// Load test image
ImageEnView1.IO.LoadFromFile( 'D:\TestImage.jpg' );

  

// Output the maximum of each pixel of the left and right halves of the image
bw := ImageEnView1.IEBitmap.Width;
bh := ImageEnView1.IEBitmap.Height;
bmp  := TIEBitmap.Create( ImageEnView1.IEBitmap, Rect( 0, 0, bw div 2 - 1, bh - 1 ));   // Left half
bmp2 := TIEBitmap.Create( ImageEnView1.IEBitmap, Rect( bw div 2, 0, bw - 1, bh - 1 ));  // Right half
ImageEnView1.IEBitmap.Allocate( bmp.Width, bmp.Height );
ImageEnView1.IEBitmap.GetIEVisionImage().max( bmp.GetIEVisionImage(), bmp2.GetIEVisionImage() );
ImageEnView1.Update(); // Show changes in our viewer
bmp.Free();
bmp2.Free();
