Hello,
I just updated from Delphi 12.3 to Delphi 13.1, for which I also installed the latest Imageen version (from 14.0.0 to 15.0.0).
In one of my programs I have implemented an option to load the iepdf32.dll from a certain location under a different name instead of as "iepdf32.dll".
For this explicit purpose I use gPDFiumDllFileName and set it to the full path of the DLL under its different name.
In Imageen 14 this worked fine, in Imageen 15 the program isn't able to find the dll anymore.
Since I have the source code of both versions I compared the units and it seems to me that in "iexPDFiumCore" in the function "InitPDFiumLib" the usage of gPDFiumDllFileName is completely broken:
If gPDFiumDllFileName isn't empty, "DLLPath" is set to gPDFiumDllFileName + '\', then afterwards "InitPDFiumEx" is executed on DLLPath + "iepdf32.dll", which in my case amounts to something like "...\myname.dll\iepdf32.dll", which obviously cannot ever work.
In Imageen 14.0.0 gPDFiumDllFileName was used directly for InitPDFiumEX instead if not empty.
I would be grateful if that could be fixed, as I can't see an easy workaround without editing the Imageen source code, which I would like to avoid if possible. |

Thanks for the report. I'm out of the office until next week, so will need to check after that.
Can you tell me whether it also fails if you pass the full path to RegisterPlugIns (which is the documented method):
IEGlobalSettings().RegisterPlugIns( 'C:\My Dlls\MyApp\XyzViz.DLL', [iepiPDFium] );

Yes, I've tried that first but that fails too because RegisterPlugIns eventually also calls InitPDFiumLib with that full path as parameter DLLPath.
Unfortunately InitPDFiumLib was changed in such a fashion that both the parameter DLLPath and gPDFiumDllFileName are treated as folder paths without filename, to which then "iepdf32.dll" is added categorically.
So if your DLL isn't named "iepdf32.dll", trying to load it will always fail. |

OK, thanks for the testing that. I'll send you a beta next week to resolve this.

Hi
Please email us for the latest beta which fixes this.
Note: You now need to pass a path to RegisterPlugIns() rather than use gPDFiumDllFileName
