1. To be able to load and display SVG files in this demo:
\Demos\LayerEditing\SVGVectorLayers
... must ALL 47 (!) files in this folder:
\ImageMagickPlugIn1100\Binaries 32bit\Core_Files
... be deployed in the demo exe directory or only a part of these files?

2. Is it possible to place these DLL files in a subdirectory in the folder of the exe file (and then point to this subdirectory at runtime)?

3. How can I programmatically restore the original aspect ratio of the SVG Layer?:



I've tried this, but it does not work:



procedure TForm1.ButtonRestoreAspectRatioClick(Sender: TObject);
begin
  IELayerRestoreAspectRatio1.Execute;
end;

Hi Peter

1. SVG loading requires ImageMagick, so you must include all ImageMagick files.

2. You can specify a path as follows:

procedure TForm1.RegisterImageMagick();
const
  IMAGEMAGICK_FOLDER = 'E:\ImageMagick_Dev\Test32\';
begin
  // Register the ImageMagick plug-in if available
  IEGlobalSettings().RegisterPlugIns( IMAGEMAGICK_FOLDER, [iepiImageMagick] );
end;


3. The demo does not consider the aspect ratio of the SVG image (layer does not know it). You would need to handle this yourself, e.g. by locking the aspect ratio when loading:

ImageEnView1.IO.Params.Dict.Insert( 'ImageMagick:AspectRatio', 1 );
