TIEImageEnGlobalSettings.JPEG2000Engine

Declaration

property JPEG2000Engine: TIEImagingEngine;

Description

Specifies which engine is used to load and save JPEG2000 format images.

Property	Description
ieenAuto	Automatically chooses ieenDLL if a DLL is found in the EXE folder, otherwise ieenNative (32bit only)
ieenNative	Uses native loading code (32bit only)
ieenDLL	Uses an ImageEn DLL to support the file format. This option gives the best performance and functionality
ieenWIC	N/A
ieenLegacy	N/A

Notes:
- ieenDLL requires you to ship the IELib or IEVision DLL with your application.
- With ieenAuto, only the EXE folder is searched for relevant DLL's. For ieenDLL, the system path is also checked (or explicitly call RegisterPlugins)

Default: ieenAuto (which uses ieenDLL if a DLL is available, otherwise ieenNative in 32bit apps)

Examples

// Use native code to load JPEG2000 images even if DLL is available
IEGlobalSettings().JPEG2000Engine := ieenNative;

// 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 If the DLL is not found or is outdated, an error will be raised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;
