TIOParams.EXIF_HasEXIFData
Declaration
property EXIF_HasEXIFData: Boolean;
Description
If True, the loaded image contains
EXIF information tags. EXIF data is commonly added by digital cameras to provide meta data on a photo.
Note: If you do not wish to maintain the original EXIF info, set EXIF_HasEXIFData to False before saving.
Typical situations:
1) You want to maintain the EXIF data untouched:
Do nothing... (default behavior)
2) You want to set some EXIF fields, e.g.
ImageEnView1.IO.Params.EXIF_Software := 'ImageEn';
ImageEnView1.IO.Params.EXIF_HasEXIFData := true;
3) You want to remove all EXIF data:
ImageEnView1.IO.Params.ResetEXIF();
| Demos\InputOutput\EXIF\EXIF.dpr |
// Remove EXIF data from image.jpg
ImageEnView1.IO.Params.EXIF_HasExifData := False;
ImageEnView1.IO.InjectJpegEXIF('D:\image.jpg');
// Update the GPS EXIF data in a file
io := TImageEnIO.create(nil);
try
io.ParamsFromFile( FilenameStr );
io.Params.EXIF_GPSLatitude := GPSLatitudeFloat;
io.Params.EXIF_GPSLongitude := GPSLongitudeFloat;
io.Params.EXIF_GPSVersionID := GPS_Version_ID;
io.Params.EXIF_HasEXIFData := True;
io.InjectJpegEXIF( FilenameStr );
finally
io.Free;
end;
// Update EXIF date for the current file
ImageEnView1.IO.Params.EXIF_DateTime2 := Now;
ImageEnView1.IO.Params.EXIF_DateTimeOriginal2 := Now;
ImageEnView1.IO.Params.EXIF_HasEXIFData := True;
ImageEnView1.IO.InjectJpegEXIF( ImageEnView1.IO.Params.Filename );
