TIOParams.RAW_HalfSize

Declaration

property RAW_HalfSize: Boolean;

Description

Set to True before loading to retrieve only a half-size image of a Raw image. This will speed up loading.

Default: False (Specified by IOParamDefaults)

Raw Loading Speed

ImageEn offers four properties to improve loading speed for RAW images:
◼ RAW_GetExifThumbnail
◼ RAW_GetEmbeddedJpeg
◼ RAW_EmbeddedJpegLoading
◼ RAW_HalfSize

Example usage:

// Load the full size RAW
ImageEnView.IO.Params.RAW_GetExifThumbnail := False;
ImageEnView.IO.Params.RAW_GetEmbeddedJpeg := False;
ImageEnView.IO.Params.RAW_HalfSize := False;

// Load the half size RAW
ImageEnView.IO.Params.RAW_GetExifThumbnail := False;
ImageEnView.IO.Params.RAW_GetEmbeddedJpeg := False;
ImageEnView.IO.Params.RAW_HalfSize := True;

// Load the embedded JPEG (loading a half size raw if there is no embedded JPEG)
ImageEnView.IO.Params.RAW_GetExifThumbnail := False;
ImageEnView.IO.Params.RAW_GetEmbeddedJpeg := True;
ImageEnView.IO.Params.RAW_HalfSize := True;

// Load the thumbnail (will automatically fall back to the embedded JPEG if there is no thumbnail)
ImageEnView.IO.Params.RAW_GetExifThumbnail := True;
ImageEnView.IO.Params.RAW_GetEmbeddedJpeg := True;
ImageEnView.IO.Params.RAW_HalfSize := True; // In case there is no EXIF thumbnail or embedded JPEG

Example

ImageEnView1.IO.Params.RAW_HalfSize := True;
ImageEnView1.IO.LoadFromFile('C:\CRW_0001.CRW');
