Optional DLLs for 32bit Applications:

Optional DLLs for 64bit Applications:

Notes:
- All DLLs are optional and ImageEn can fully function as a stand-alone EXE. Though for a 64bit EXE, ielib64.dll (or ievision64.dll) is highly recommended
- If you are using IEVision.dll/IEVision64.dll you do NOT need ielib32.dll/ielib64.dll, because IEVision includes all code of ielib
- Other plug-ins are available such as ImageMagick (for wider format support): www.imageen.com/download/

You must register the DLLs each time your application runs using RegisterPlugIns. It is recommended that ImageEn DLLs are installed to the same folder as your EXE.
More information is available on distributing IEVision.

IELIB32.DLL

ielib32.dll is an optional library for 32bit ImageEn applications, but it is 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

IELIB64.DLL

ielib32.dll is a highly recommended library for 64bit applications. If ielib64.dll is unavailable:

• 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

File Support Overview

ImageEn supports native loading of the following formats: JPEG*, JPEG2000*, PNG*, GIF, BMP, TIFF, Icons, DICOM, PhotoShop, WMF, EMF, Cursors, AVI, PCX, DCX, Targa, PXM, Wireless BMP
* In 64bit applications a DLL is used

For JPEG, PNG, RAW and JPEG2000, there are multiple loading engines available: Native (to avoid using a DLL), DLL (for Speed) and WIC (fallback option). The engine can be specified using 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 If the DLL is not found or is outdated, an error will be raised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):
