Description

Class of IOParamDefaults to specify defaults for load properties when initializing all TIOParams objects.

Some properties of TIOParams objects affect the way images are loaded. It can be useful to set these globals, which will affect the loading of all images in TImageEnView, TImageEnMView, TImageEnFolderMView, TIEBitmap and TIEMultiBitmap.

Property	TIOParam Property	Default Value
EnableAdjustOrientation	EnableAdjustOrientation, JPEG_EnableAdjustOrientation and TIFF_EnableAdjustOrientation	False
RAW_AutoAdjustColors	RAW_AutoAdjustColors	False
RAW_HalfSize	RAW_HalfSize	False
RAW_GetEmbeddedJpeg	RAW_GetEmbeddedJpeg	False
RAW_EmbeddedJpegMinWidth	RAW_EmbeddedJpegMinWidth	800
RAW_EmbeddedJpegMinHeight	RAW_EmbeddedJpegMinHeight	800
RAW_EmbeddedJpegLoading	RAW_EmbeddedJpegLoading	ierlDefault
RAW_Interpolation	RAW_Interpolation	ieRAWInterpolationLinear
RAW_QuickInterpolate	RAW_QuickInterpolate	True
RAW_UseAutoWB	RAW_UseAutoWB	False
RAW_UseCameraWB	RAW_UseCameraWB	False
JPEG_DCTMethod	JPEG_DCTMethod	ioJPEG_ISLOW
JPEG_Quality *	JPEG_Quality, TIFF_JPEGQuality, DICOM_JPEGQuality, ImageQuality	80
JPEG_Scale	JPEG_Scale	ioJPEG_FULLSIZE
PSD_LoadLayers	PSD_LoadLayers	False
DICOM_Range	DICOM_Range	iedrAdjust

* JPEG_Quality only affects saving, not loading, but is included because of its frequent usage

Examples

// For all loading, automatically rotate images to their correct orientation
IEGlobalSettings().IOParamDefaults.EnableAdjustOrientation := True;

// Improve the colors of Raw camera images added to a TIEMultiBitmap
IEGlobalSettings().IOParamDefaults.RAW_AutoAdjustColors := True;
IEGlobalSettings().IOParamDefaults.RAW_UseAutoWB := True;
IEGlobalSettings().IOParamDefaults.RAW_UseCameraWB := True;
MyMultiBitmap.FillFromDirectory( 'E:\DCIM\' );

// Faster loading for all Camera Raw images
IEGlobalSettings().IOParamDefaults.RAW_HalfSize := True;
IEGlobalSettings().IOParamDefaults.RAW_GetEmbeddedJpeg := True;
