TImageEnMView.MultiSelectedImagesCount


Declaration

property MultiSelectedImagesCount: Integer;


Description

MultiSelectedImagesCount returns the number of selected images. Selected indexes are returned by MultiSelectedImages.

// Replace all selected images with 'new.jpg'
for i := 0 to ImageEnMView1.MultiSelectedImagesCount - 1 do
begin
  selIdx := ImageEnMView1.MultiSelectedImages[ i ];
  ImageEnMView1.SetImageFromFile( selIdx, 'new.jpg' );
end;


// Rotate selected images right (90 clockwise)
for i := 0 to ImageEnMView1.MultiSelectedImagesCount - 1 do
begin
  selIdx := ImageEnMView1.MultiSelectedImages[ i ];
  bmp := ImageEnMView1.GetTIEBitmap( selIdx );
  bmp.Rotate( 270 );
  ImageEnMView1.ReleaseBitmap( selIdx, True );
end;
ImageEnMView1.Update();


// Get filenames of all selected files
lbxFilenames.clear;
for i := 0 to ImageEnMView1.MultiSelectedImagesCount - 1 do
begin
  selIdx := ImageEnMView1.MultiSelectedImages[ i ];
  lbxFilenames.Items.Add(ImageEnMView1.ImageFileName[selIdx]);
end;


// Access files in the order that user selects them
ImageEnMView1.MultiSelectionOptions := ImageEnMView1.MultiSelectionOptions + [iemoDontSortMultiSelection];
for i := 0 to ImageEnMView1.MultiSelectedImagesCount - 1 do...
