Read Specific EXIF tag

[nicephore]

Hi
I'm trying read specific EXIF tags so i try:

var
Value: PChar;

libGfl.gflBitmapGetEXIFValue(@GFL_BMP, $112, Value, 255);
...
Memo1.Lines.Add('Tag $112: ', + Value);

But Value is always empty ...

Where's my error ? Thanks for help

i have find my error:

replace: libGfl.gflBitmapGetEXIFValue(@GFL_BMP, $112, Value, 255);
by
libGfl.gflBitmapGetEXIFValue(GFL_BMP, $112, Value, 255);
