ImageEn

ImageEn DLLs


These are the optional DLLs for a 32bit EXE using ImageEn:

DLL Description Availablity
ielib32.dll Improves image support, including digital camera raw formats and faster image I/O performance In the ImageEn install folder
IEVision.dll Adds advanced features, like OCR, barcode recognition and facial recognition Sold separately
ielang32.dll Adds localization in twenty-five languages In the ImageEn install folder
iepdf32.dll Allows viewing and manipulation of PDF files using PDFium http://www.imageen.com/download/

These are the optional DLLs for a 64bit EXE using ImageEn:

DLL Description Availablity
ielib64.dll Signficantly improves image support, including digital camera raw formats In the ImageEn install folder
IEVision64.dll Adds advanced features, like OCR, barcode recognition and facial recognition Sold separately
ielang64.dll Adds localization in twenty-five languages In the ImageEn install folder
iepdf64.dll Allows viewing and manipulation of PDF files using PDFium http://www.imageen.com/download/

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): http://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

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

By default, they are as follows:
Configuration JPEG PNG Camera RAW Other Images
32bit with DLL DLL DLL DLL Native
32bit without DLL Native Native WIC (not all formats supported) Native
64bit with DLL DLL DLL DLL Native
64bit without DLL WIC WIC WIC (not all formats supported) Native


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;
