I'm attempting to create multiple JPG files from a PDF file. I don't see how I'm even able to load the file.
var
io: TImageEnIO;
count : integer
begin
io.LoadFromFile(PDFFileName);
count := IEGetFileFramesCount(filename);
It doesn't seem to be loading anything into the io. I'm a little confused by this. I'm able to save files to pdf, but I can't seem to load them. Should I be using a stream or another object(other than TImageEnIO)?
Thanks in advance.

Hi
Also there are ImageMagick images and a test project at:

Hi
You do npt need to interact with ImageMagick directly. Once you have installed ImageMagick and Ghostscript, then ImageEn should be able to load PDF files.
Please ensure you read the tip regarding 32/64bit at:
http://www.imageen.com/ieforum/topic.asp?TOPIC_ID=1464
Then try loading ImageMagick only formats (such as SVG) and then PDF into ImageEn.

I followed the directions and, installed both ImageMagick and Ghostscripts. I was able to the conversion from the command line, but couldn't get the calls to work via delphi application. I downloaded and build the "PascalMagick-4.0" .pas libraries, but if I try to incorporate the Demonstration Program 1 here:
http://wiki.freepascal.org/PascalMagick#Download
If I use any reference to the library code, the program crashes immediately with no error message at all. It's really strange.
I have even tried:
cmd := 'C:\Program Files\ImageMagick-6.9.0-Q16\convert.exe';
//debug
input := '"c:\temp\temp.pdf" "c:\temp\temp2222.jpg"';
cmd := cmd + ' ' + input;
FillMemory( @si, sizeof( si ), 0 );
si.cb := sizeof( si );
CreateProcess(
nil,
// path to the executable file:
PChar(cmd),
Nil, Nil, False,
NORMAL_PRIORITY_CLASS, Nil, Nil,
si, pi );
// "after calling code" such as
// the code to wait until the
// process is done should go here
CloseHandle( pi.hProcess );
CloseHandle( pi.hThread );
I'm beginning to think it's just not compatible with Delphi... |

Hi,
To be able to load PDF into ImageEn, you must enable ImageMagick plugin
and also, GhostScript must be installed on your PC.
Here is a topic with more details:
