IMAGEEN DLLS

There are four standard DLL's of ImageEn. Only one is needed.


You need only distribute one of these DLL's with your application, because:
- IEVision.dll (32bit) includes all code of ielib32.dll
- IEVision64.dll (64bit) includes all code of ielib64.dll

You can register the plug-ins using RegisterPlugIns and check availability using ActivePlugIns.
More information is available on distributing IEVision.

Note: Versions prior to v6.1.0 used dcraw.dll for digital camera raw image support. From v6.1.0, use ielib*.dll or ievision*.dll instead.

32BIT APPLICATIONS: IELIB32.DLL

ielib32.dll is an optional library for ImageEn applications, but it is highly recommended because it adds
- Better support for digital camera raw formats
- Optimized loading code for JPEG, PNG and JPEG2000, which is approximately 30% faster than the native Delphi code

Ideally ielib32.dll should be placed in the same folder as your EXE, but it can also be located on the system path.

64BIT APPLICATIONS: IELIB64.DLL

ImageEn can build 64bit applications with Delphi/C++ Builder XE2 and newer. It is highly recommended that you ship the library, ielib64.dll, with your application. If ielib64.dll cannot be found:

- JPEG2000 images are unsupported
- JPEG will fallback to loading/saving via WIC (Windows) and may not include some meta-data
- PNG will fallback to loading/saving via WIC (Windows)
- Camera RAW will fallback to loading via WIC (Windows), which does not support as many RAW formats

Ideally ielib64.dll should be placed in the same folder as your EXE, but it can also be located on the system path.

File Support Overview

The engine used to load image formats depends on the following properties:
- JPEGEngine
- PNGEngine
- CameraRawEngine
- JPEG2000Engine

By default, they are as follows:

Examples

// Force use of IELib DLL for improved performance
// ImageEn will attempt to load the DLL even if it's not in the EXE folder. If the DLL isn't found or is an old version, an error will be raised
IEGlobalSettings().JPEGEngine := ieenDLL;
IEGlobalSettings().PNGEngine := ieenDLL;
IEGlobalSettings().JPEG2000Engine := ieenDLL;
IEGlobalSettings().CameraRawEngine := ieenDLL;

// Use IELib DLL if found in the EXE folder, otherwise fall back to Native or WIC
// Note: This is the default setting
IEGlobalSettings().JPEGEngine := ieenAuto;
IEGlobalSettings().PNGEngine := ieenAuto;
IEGlobalSettings().JPEG2000Engine := ieenAuto;
IEGlobalSettings().CameraRawEngine := ieenAuto;

DLL Version History

You should use the DLL version that matches your release of ImageEn (see ImageEnVersion.IELibVersionStr):

Other Plug-Ins

ImageEn supports other plug-ins for adding formats and functionality. These include:
- PDFium: Viewing and manipulation of PDF files
- ImageMagick: Support for a wider range of image formats

You can download the plug-ins from: http://www.imageen.com/download/
