I have trouble running pdftohtml.exe. It complains "freetype.dll" is missing (even though it *is* present in DLL dir)

Depending which version of pdftohtml.exe (Dynamic vs Static) you run, you may need the following dlls:

• freetype.dll
• jpeg.dll
• libpng12.dll
• zlib1.dll

These DLLs are found in the DLLs/ directory under Calibre Portable/Calibre/. You can do 1 of two things:

1. Copy those DLLs into the same directory as pdftohtml.exe
2. (Temporarily) add the path to the DLL directory to $ENV{PATH} in your script:
   

   {
       local $ENV{PATH} = $ENV{PATH}.";<PATH TO DLLs>;"
       system "pdftohtml.exe", "-xml", "<PDF FILE>";
   }
