Can anyone show me, how to open a *.PDF file and save all pages to images?
I've installed ImageMagic and GhostScript and I don't know what to do next. |

I read the topic and I can't open pdf file.
In ImageMagic demo I see 32bit Plug-In NOT FOUND, but it is installed.

I have not used imagemagic much except for some testing years ago. I get the same result... "32bit Plugin not found". My dll was from 2005 so maybe the latest dll is required. I too installed imagemagick and ghostscript. I will be discussing this with Nigel to see if we can get this working correctly.

Hi
Are you sure you downloaded the 32bit version of the ImageMagick DLL and not the 64bit one?

I've installed older version of ImageMagic and now demo program works.
But when I open any pdf file pages are poor quality (low resolution).
How to increase quality? |

Also, the ImageMagick version we tested against was:
ImageMagick-7.0.1-10-Q16-x86-dll.exe

OK, now I can open a one page of *.pdf file.
ImageEnView1.IO.Params.ImageIndex := 1;
ImageEnView1.IO.Params.Dict.Insert('PDF:Density', 200);
ImageEnView1.IO.LoadFromFile(OpenDialog1.FileName);
But how to read count of pages from pdf file?
Is it possible to load all pages at once? |

It is not possible to load all pdf pages or any multi-frame image into TImageEnView. TImageEnView can display only one image at a time. TImageEnMView was designed to hold multiple bitmaps of a multi-frame image, so this should be used instead of TImageEnView for this purpose. When you select a frame in TImageEnMView it can be displayed in TImageEnView by copying the selected bitmap to TImageEnView for editing or viewing.
To load a multi-frame image into TImageEnMView:
ImageEnMView1.MIO.LoadFromFile(iFileName);
To display a TImageEnMView selected frame in TimageEnView:
procedure TForm1.ImageEnMView1ImageSelect(Sender: TObject; idx: Integer);
begin
ImageEnMView1.CopyToIEBitmap(idx, ImageEnView1.IEBitmap);
ImageEnView1.Update;
end;
How to read count of pages from pdf file?
ImageEnMView1.ImageCount = count of pages.

| Is I have to install imagemagick and ghostscript on all client machines or only once on a server machine where an exe file is? |

Hi
ImageMagick and GhostScript need to be installed on each system to use PDF.
However we are expecting to see a new PDF DLL soon from a third party which you can just ship with your exe.

I've also installed the older version of ImageMagic but the demo still gives the message that the plug-in cannot be found.
Any ideas? |

| I've solved the issue. I just rebooted the computer and now the demo does recognize the ImageMagick plug-in! |

Yes, that is true. I will add a reminder to restart to the install instructions.

Unfortunately, this code does not work.
iop.Imagecount always returns a value of 1 even if there are multiple pages in the PDF file.
Is there a way through the ImageMagick PlugIn to get the page count of a PDF file?
Thank you. |

Hi
For performance reasons, ImageCount isn't set when using the ImageMagick plug-in.
Either use IEGetFileFramesCount():
http://www.imageen.com/help/IEGetFileFramesCount.html
(Which does not support all PDF file types).
Or TIEMiscPluginsImageMagick_PDFFrameCount().
From v6.3.1, you will be able to use IEGetFileFramesCount for all PDF types using whatever plug-in is available (Ghostscript or the new WP PDF support).
