TImageEnMView.BeginSelectImages

Declaration

procedure BeginSelectImages();

Description

Call BeginSelectImages() and EndSelectImages to select multiple images without refreshing the component's state.

Generally this will speed up the selection process.

Note: BeginSelectImages will reset the existing selection

Examples

// select the first 100 images
ImageEnMView1.BeginSelectImages();
for i := 0 to 99 do
  ImageEnMView1.SelectedImage := i;
ImageEnMView1.EndSelectImages();

// Save only checked images
wasMS := ImageEnMView1.EnableMultiSelect;
try
  ImageEnMView1.LockUpdate();
  ImageEnMView1.EnableMultiSelect := True;

  ImageEnMView1.Deselect();
  ImageEnMView1.BeginSelectImages();
  for i := 0 to ImageEnMView1.ImageCount - 1 do
    if ImageEnMView1.Checked[i] then
      ImageEnMView1.SelectedImage := i;
  ImageEnMView1.EndSelectImages();

  ImageEnMView1.MIO.SaveToFile( 'C:\Images.tiff', ioUnknown, True );

finally
  ImageEnMView1.EnableMultiSelect := wasMS;
  ImageEnMView1.UnlockUpdate();
end;
