TIEImageEffectsList.LoadFromFile

Declaration

procedure LoadFromFile(const FileName: String; Append: Boolean = False);

Description

Load a list of Image Processing effects (i.e. used to perform a set of operations upon an image).

Note:
◼LoadFromFile only works with files saved using SaveToFile
◼You do NOT need to call ImageEnView1.Update() after calling Delete(). It will update automatically

Examples

// Apply effects in a chain file to current image
if OpenDialog1.Execute() then
begin
  ImageEnView1.IEBitmap.EffectsChain.Enabled := True;
  ImageEnView1.IEBitmap.EffectsChain.LoadFromFile( OpenDialog1.FileName );
  ImageEnView1.IEBitmap.EffectsChain.Apply();
end;

// Load effects chain from file and apply the effects to a list of images
bmp := TIEBitmap.Create();
for i := 0 to ssFiles.Count - 1 do
begin
  bmp.LoadFromFile( ssFiles[i] );
  bmp.EffectsChain.Enabled := True;
  bmp.EffectsChain.LoadFromFile( 'D:\Effects.ieeff' );
  bmp.EffectsChain.Apply();
  bmp.SaveToFile( ChangeFileExt( ssFiles[i], '_convert.jpg' );
end;
bmp.Free();

// Save an effects chain to file
var
  opList: TIEImageEffectsList;
  op: TIEImageEffect;
begin
  opList := TIEImageEffectsList.Create();
  op := TIEImageEffect.Create();
  try
    // Reduce size by half
    op.Operation            := peResize;
    op.Resize_Width         := 50;
    op.Resize_Height        := 50;
    op.Resize_ByPercent     := True;
    op.Resize_QualityFilter := rfLanczos3;
    opList.Add( op );

    // Enhance contrast
    op.Operation         := peContrast;
    op.Contrast_Contrast := 20;
    opList.Add( op );

    // Rotate 45 deg. clockwise
    op.Operation              := peRotate;
    op.Rotate_Angle           := -45;
    op.Rotate_BackgroundColor := clBlack;
    op.Rotate_Antialias       := ierFast;
    opList.Add( op );

    opList.SaveToFile( 'D:\Effects.chain' );
  finally
    opList.Free;
    op.Free;
  end;
end;

// Apply effects in a chain file to current image
ImageEnView1.IEBitmap.EffectsChain.Enabled := True;
ImageEnView1.IEBitmap.EffectsChain.LoadFromFile( 'D:\Effects.chain' );
