Declaration

TIEVisionImage = interface(TIEVisionBase)

Description

An interface to handle raster images (or matrices) of the type required by IEVision.
It is possible to perform basic input/output operations and several image processing tasks. You can also connect a TIEVisionImage to a TIEBitmap, sharing the same content.

To convert a TIEBitmap to a TIEVisionImage use GetIEVisionImage:

vizImage := ImageEnView1.IEBitmap.GetIEVisionImage();

To convert a TIEVisionImage to a TIEBitmap use AssignIEVisionImage:

ImageEnView1.IEBitmap.AssignIEVisionImage( vizImage );

For TBitmap you can assign it first to a TIEBitmap.

Examples

// Create empty image
image := IEVisionLib.createImage();

// Create an image from "input.jpg", resize to 100x100 and save as "output.jpg"
image := IEVisionLib.createImage('input.jpg');
image.resize(100, 100); // default interpolation = linear
image.save('output.jpg');

// Create an image of 1000x1000x24 bit
image := IEVisionLib.createImage(1000, 1000, ievUINT8, 3);

// Create an image from the TIEBitmap of a TImageEnView (sharing the content)
ImageEnView1.IEBitmap.Origin := ieboTOPLEFT;
image := IEVisionLib.createImage(ImageEnView1.IEBitmap.Width, ImageEnView1.IEBitmap.Height,
                                 ievUINT8, 3, ImageEnView1.IEBitmap.Rowlen,
                                 ImageEnView1.IEBitmap.ScanLine[0]);

// Same as previous code
image := ImageEnView1.IEBitmap.GetIEVisionImage();


var
  images: TIEVisionVectorImageRef;
  i: Integer;
  pano: TIEVisionImage;
  status: TIEVisionStitchingStatus;
begin
  images := IEVisionLib.createVectorImageRef();
  for i := 1 to 6 do
    images.push_back(IEVisionLib.createImage('image' + IntToStr( i ) + '.jpg'));
  pano := IEVisionLib.createStitcher().stitch(images, status);

  if status = ievSSOK then
    ImageEnView1.IEBitmap.AssignIEVisionImage(pano);
end;
