Hi
ImageEn v4.1.4 includes a beta of our new loading DLL, ielib32.dll. This optional library provides no functionality other than that included in the native ImageEn libraries, however due to optimized compilation you will find file loading is approximately 30% faster with it.
To use ielib32.dll you will need to edit ie.inc and change:
{.$define IEUSEDLLJPEGLIB}
{.$define IEUSEDLLPNGLIB}
{.$define IEUSEDLLJPEG2000LIB}
{.$define IEUSEDLLRAWLIB}
To
{$define IEUSEDLLJPEGLIB}
{$define IEUSEDLLPNGLIB}
{$define IEUSEDLLJPEG2000LIB}
{$define IEUSEDLLRAWLIB}
You will then need to recompile your packages. Naturally you will need to ship ielib32.dll with your application. Ideally this should be placed in the same folder as your EXE, but it can also be located on the system path.
Note: Delphi/BCB 5 and 6 are not supported

| Is the 30% across the board, or is it just for larger files? Is the improvement transferred to the thumbnail viewer as well? |

Any loading of JPEG or PNG files will be faster, whether it is for image display or thumbnails.

Hi Nigel
{$define IEUSEDLLRAWLIB}
^^
Does this include DCRAW support? Is the source code for ielib32.dll available? Will there be a 64bit version of dcrawlib.dll?
So many questions... ;)
Thx

This looks great, but I can't just see where to put this code:
{$define IEUSEDLLJPEGLIB}
{$define IEUSEDLLPNGLIB}
{$define IEUSEDLLJPEG2000LIB}
{$define IEUSEDLLRAWLIB}
Also, it says change [block of code]... to [block of code]...
but both blocks look the same.
Sorry to be stupid.
Also, can I use this DLL with ImageMagic and DCRawLib?
If so, what code do I use and where, please? Do I still use
IEFileFormatRemove(ioRAW);
IEAddExtIOPlugIn('dcrawlib.dll');
IEAddExtIOPlugIn('imagemagick.dll');Thanks

You edit the relevant $defines in the ie.inc file that comes with ImageEn and recompile the packages afterwards.
BTW: I didn't have the time to install the new version yet. Can you tell me whether the code for the DLL is supplied or not? Thanks!

Hi Uwe.
Thanks. I'll try that tomorrow (but I'm still not sure what to replace).
The DLL source code: I can't see anything like ielib32.pas or ielibxxx.pas in the source folder, but perhaps I'm looking for the wrong thing?
regards

The first batch of defines have a DOT in front of them making them inactive. Remove the DOT to make the define active.
{.$DEFINE HAPPY} // inactive
{$DEFINE HAPPY} // active |

Thanks jed. I hadn't noticed the dot.
It's starting to make more sense now.

Yes, it includes DCRAW support. Actually ielib32.dll (and ielib64.dll) includes dcrawlib.
Consider 64 bit dcrawlib in ielib64.dll. |

Hi Fabrizio
Thanks for the information; appreciate it. Although I see one potential issue here: where is the source for the DLL's? If they include Dcraw as you say, don't you have to provide the DLL code if it contains restricted functions according to the Dcraw licence?
Anyway, I really hope that the source will be available at a later point in time when ImageEn 4.1.4 has left the beta phase. And I would certainly like to assume that you will *not* go down the path and start selling ImageEn without providing the source for important parts of the library. Can you please elaborate on the latter?
Thanks
Uwe |

Hi everyonequote:
You will then need to recompile your packages.
I've tried doing this but have had no success.
Can someone explain how to do this? (I'm using Delphi 2010).
Thanks

Hi Nigel quote:
Do you mean to recompile the packages?
Yes.
I don't really know what I'm doing.
If I open and compile package DPKIECTRL10;
I get error
[DCC Fatal Error] DPKIECTRL10.dpk(36): F1026 File not found: 'IERegCtrl.dcu' at the linescontains
IERegCtrl in 'IERegCtrl.pas';
PKIECtrl10 seems to compile OK, though

The easiest way to compile your Delphi 2006 ImageEn packages is as follows:
1. Copy the files in the folder, *ImageEn*\Source\Delphi10, to your Source folder (*ImageEn*\Source\)
2. Open each of the following in Delphi and click Compile:
DPKIECTRL10.DPK, DPKIEDB10.DPK, PKIECTRL10.DPK and PKIEDB10.DPK
If you have any probems then ensure that *ImageEn*\Source\ is listed in your "Library path"

Uwe,
quote:

dcraw included in ielib.dll doesn't use restricted code (GPL code). This DLL is just a wrapper over dcraw, jpeg lib, png lib, etc.

I understand your point of view (and I agree with you). Anyway at the moment I don't know if DLL code will be available.
Specific needs are taken into account. |

Hi Nigel/Fabrizio
I've now recompiled the four packages, and put ielib32.dll in the project folder of my program.
Now, when I try to load JPEG thumbnails I get an exception in unit jpegfilt: function IEJPEG_Decomp_AllocDecompStruct():IEJPEG_Decomp_Struct; quote:
Project imagematik.exe raised exception class EIEJPEGException with message 'ievision.dll, ievision64.dll, ielib.dll
or ielib64.dll not found'.
I don't understand, because the ielib32.dll definitely is in the .exe folder.
Do you need to have ievision as well?
Or is it expecting ielib.dll, not ielib32.dll?
If so can I just rename the ielib32.dll to ielib.dll?
Or am I doing something very stupid?
regards
Patrick |

I would say rename it to ielib.dll.
It should be easily to recompile the packages as that is what I do because I don't want components in the Program Files folder. Why the package source files don't have relative links to the source location shows that the build process for ImageEN is disjointed from what is built and then delivered and should be fixed.
Relying on library paths for a component library is bad.

Thanks for quick reply, jed.
Yes, renaming ielib32.dll to ielib.dll makes it work.
Perhaps the source should be changed instead, as ielib32.dll is a better name as it shows it is 32 bit, but I'll leave that to Nigel or Fabrizio to sort out.
Loading is much faster, quite an impressive improvement.
regards

V4.1.4: DLL to speed up file loading
