Compatibility Issues

◼Changed: Casing has changed to some identifiers. C++Builder users should run the Compatibility Fixer or add \Source\Legacy\IELegacy.hpp to your project
◼Changed: TImageEnView.BackBuffer has been deprecated. Instead use BackBufferImage
◼Changed: Alpha channel cut-off for GIF files is now specified with DefaultAlphaThreshold rather than set to 255
◼Removed: gPDFiumDllFileName has been removed, instead pass a custom path to RegisterPlugIns
◼Changed: Standarization of some global method names: TRGB2TColor ➔ IERGBToColor, TRGB2TColor ➔ IERGBToColor, RGB2TColor ➔ IERGBToColor, TColor2TRGB ➔ IEColorToRGB, TColor2TRGBA ➔ IEColorToRGB, TColor2TRGBA ➔ IEColorToRGBA, TRGB2TRGBA ➔ IERGBToRGBA, TRGB2TRGBA ➔ IERGBToRGBA, TRGBA2TRGB ➔ IERGBAToRGB, HSV2RGB ➔ IEHSVToRGB, HSL2RGB ➔ IEHSLToRGB, RGB2HSL ➔ IERGBToHSL, RGB2HSV ➔ IERGBToHSV, IEStrToFloatDefS ➔ IEStrToFloatDef, IEBool2StrS ➔ IEBoolToStr, IERGB2YCbCr ➔ IERGBToYCbCr, IEExtractFileExtS ➔ IEExtractFileExt
◼Changed: Password support for SevenZip and PDF (IEGlobalSettings().AutoPromptForPassword and IEGlobalSettings().OnPassword) have now been moved to TImageEnIO.AutoPromptForPassword/TImageEnMIO.AutoPromptForPassword and TImageEnIO.OnPassword/TImageEnMIO.OnPassword/TImageEnView.OnPassword/TImageEnMView.OnPassword
◼Changed: The default for AutoPromptForPassword is now False
◼Deprecated: IEGlobalSettings().EnableCMS (which defaulted to False) has been deprecated in favor of ColorProfileMode. Enabling EnableCMS will force ColorProfileMode := iecpApply. Rather than setting EnableCMS, you should use ImageEnView1.IEBitmap.ColorProfileMode := iecpApply; (before loading your image)
◼Removed: IEGlobalSettings().ApplyColorProfileOnRendering (which defaulted to True) has been removed in favor of ColorProfileMode. Rather than setting ApplyColorProfileOnRendering, you should use ImageEnView1.IEBitmap.ColorProfileMode := iecpRender; or ImageEnView1.IEBitmap.ColorProfileMode := iecpIgnore;
◼Changed: If you get errors for TIOFileType items, like ioJPEG or ioPNG, ensure that iexDefs is included in your uses clause
◼Removed: Some older file formats (PCX, DCX, Targa and PXM) are not automatically detected by their content
◼Deprecated: ImageEnView1.IO.TwainParams.CompatibilityMode has been deprecated. Instead of setting CompatibilityMode := True, use IEGlobalSettings().TwainCompatibilityOptions := IEGlobalSettings().TwainCompatibilityOptions + [ietcDontGetCapabilities, ietcForceFileTransferMode];
