I want to open PDF using ImageMagic and GhostScript.

Installed the ImageMagic plugin from the developer's website and connected it to the program (checked the registraration).
The GhostScript plugin is installed.

Use
ImageEnView1->LoadFromFile (or LoadFromFilePDF)

I get an error about the absence of iepdf32.dll (But I wouldn't like to use PDFium)

Hi

At the start of your application, please call:

TIEMiscPluginsImageMagick.RegisterPlugin( '', True );

Hi,

I use

IEGlobalSettings()->RegisterPlugIns(MyImageMagickPath, TIEPlugIns() << iepiImageMagick);

This is not enough?

Hi

It is a class method, so that should read:

TIEMiscPluginsImageMagick::RegisterPlugin(MyImageMagickPath, true);

The error is gone. Thank you.
Where is the quality (resolution) of the resulting raster images of a PDF file set?

For ImageMagick you need to set the density:

ImageEnView1.IO.Params.Dict.Clear();
ImageEnView1.IO.Params.Dict.Insert( 'ImageMagick:Density', 200 );
ImageEnView1.IO.LoadFromFile( 'D:\doc.pdf' );
