Hello, this is the code I use in my program Imagen3D to display data IPTC: var NItems : integer; Iptc : PGFL_IPTC_DATA; .... begin ... if gflBitMapHasIPTC(gfl_bmp) = gfl_no_error then begin IPTC := gflLoadIPTC(Pchar(FileName)); NItems := IPTC.NumberOfItems; for i := 0 to NItems-1 do begin ShowIPTC(I...

I'll try this new version and I will indicate to you the results of my tests.

Hi,

Changed many function parameters to use VAR instead of pointers, where it makes sense

This version has many changes from previous version. Such changes require modifying a lot of code in programs and that is a problem.

Hi,
you're right. The function gflBitmapSetEXIFValueRationalArray2 is not implemented in version 3.11.
Frankly, my level of programming in Delphi is low, as my English level.
I hope this new version of the interface for delphi.
Thanks and regards ...

Hello, There are some errors in libgfl.pas: function gflSetColorAt(src: PGFL_BITMAP; x, y: GFL_INT32; var color: TGFL_COLOR): GFL_ERROR; stdcall; GFL_EXIF_MAIN_IFD = $0002; GFL_EXIF_IFD_0 = $0001; function gflBitblt(src: PGFL_BITMAP; rect: PGFL_RECT;dst: PGFL_BITMAP; x_dest, y_dest: GFL_INT32): GFL_...

Hi, I am using version 3.15 of GFL SDK. If I Load an image and saving it, EXIF data are saved correctly: gflLibraryInit(); gflGetDefaultLoadParams(mLoadOption); mLoadOption.Flags := GFL_LOAD_READ_ALL_COMMENT; mLoadOption.Flags := GFL_LOAD_METADATA; mError := gflLoadBitmap(Pchar(FileName1),mOriBitmap...

I think it would be an interesting option to prevent degradation of the jpg image when we want to add, for example, the GPS data.

Hi,
Is it possible to save the EXIF data of an image without having to load and then save the image? It would be the equivalent instruction "gflSaveIPTC"

Miguel Angel

Thank you very much!

Hello Pierre, I have sent you the file at: <-- removed* --> The code used is as follows (Delphi): var Lat_pq,Long_pq : array[0..5] of integer; PosicionXgpsRef,PosicionYgpsRef : string; ppp : integer; .... begin .... //GPS PosicionYgpsRef := 'N'; PosicionXgpsRef := 'W'; Lat_pq[0] := 28; Lat_pq[1] := ...

Hi,
you have been able to find out what is wrong?

Miguel Angel

Thank you,
with XnView you can even see the first image and EXIF data.

Hi,
In this link there are examples of file in MPO format.

About MPO format:

Would it be possible to incorporate this format in GFL SDK?
