In the library libgfl.pas (Delphi) does not appear GFL_EXIF_WANT_MAKERNOTES and the HELP of library is out of date.
¿Can you indicate one example to get Makernotes?
Thanks

The XnView program, shows the EXIF data belonging to the group Makernote . However, with the function gflLoadExif not appear this values (ISO, etc).
How can I see this values EXIF?

Exif := gflLoadExif(Pchar(FileName1),0);
NItems := Exif.NumberOfItems;
for i := 0 to NItems-1 do
begin ...

Hello, replacing the code

Code: Select all

EXIF := gflBitmapGetEXIF(gfl_bmp,0);

by that other

Code: Select all

Exif := gflLoadExif(Pchar(FileName),0);

It works well. There seems to be an error in (TurboDelphi)

Code: Select all

gflBitmapGetEXIF
