Hi,
how quickly extract the jpeg from raw file (nef, cr2, etc) ?
EnableLoadEXIFThumbnails is the only way ?
Thankyou

Actually ioJPEG_AUTOCALC works only for jpeg and tiff.
For other RAWs it is only possible to extract the thumbnail:
imageenview1.IO.Params.GetThumbnail := true;
imageenview1.io.LoadFromFile('image.NEF');

//With ioJPEG_AUTOCALC you should also set the desired size
I already use it for jpeg files but it doesn't work for jpeg extracted from raw files.
How Picasa can extract and display so fast the nef and cr2 files ? (when navigating with mousewheel) |

With ioJPEG_AUTOCALC you should also set the desired size:
ImageEnView1.IO.Params.Width:=100;
ImageEnView1.IO.Params.Height:=100;
ImageEnView1.IO.Params.JPEG_Scale:=ioJPEG_AUTOCALC;
ImageEnView1.IO.LoadFromFile('....'); |

How Can i apply this param
/* IO.Params.JPEG_Scale := ioJPEG_AUTOCALC;
to the jpeg extracted from TIFF ?
Because it so slow when i try to load.
i add this param
/* IO.Params.RAW_HalfSize := True
but the result is the same !

Hi
You can extract the JPEG image from some RAw formats as follows:
DNG:
ImageEnView1.IO.Params.TIFF_SubIndex:=1;
ImageEnView1.IO.LoadFromFileTIFF('input.dng');
CR2:
ImageEnView1.IO.Params.ImageIndex:=0;
ImageEnView1.IO.LoadFromFileTIFF('input.cr2');
NEF:
ImageEnView1.IO.Params.ImageIndex:=1;
ImageEnView1.IO.LoadFromFileTIFF('input.nef');
CRW:
ImageEnView1.IO.LoadJpegFromFileCRW('input.crw');
