Exif info different in api and command line?

[Jacob]

In command line i use
identify.exe -format "%[EXIF:DateTime]" 1.jpg
and see 2006:12:20 17:30:40.
in api i use $str = MagickGetImageProfile($mw2, "%[EXIF:DateTime]");
and str empty.
$str = MagickGetImageProfile($mw2, "EXIF");
return no parsed exif block. Is it normal and any way how parse it?

P.S. Maybe have any advice or hint how make contrast picture in percent?

To return the EXIF date/time tag, use

• MagickGetImageAttribute($mw2, "EXIF:DateTime");

To return the EXIF date/time tag, use

• MagickGetImageAttribute($mw2, "EXIF:DateTime");

not work.
i use ImageMagick 6.2.4 09/11/05 Q16 1572
and $str = MagickGetImageAttribute($mw2, "EXIF:DateTime"); $str empty.

The documentation is for MagickWand 1.0.0. It has the MagickGetImageProperty() method documented. MagickGetImageAttribute() is deprecated.
