TIEGlobalSettings.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 |
ieenNone | Format is not available |
Note:
◼ieenDLL requires you to ship the
IELib or IEVision DLL with your application.
◼With ieenAuto, only the EXE folder is searched for relevant DLLs. For ieenDLL, the system path is also checked (or specify a path by calling
RegisterPlugins)
Default: ieenAuto (which uses ieenDLL if a
DLL is available, otherwise ieenNative in 32bit apps)

// Use native code to load JPEG2000 images even if DLL is available

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 If the DLL is not found or is outdated, an error will be raised
