Hello, The errors I found in "libgfl.pas" are: //function gflSetColorAt(var dst: PGFL_BITMAP; x, y: GFL_INT32; var color: TGFL_COLOR): GFL_ERROR; stdcall; [ERROR] function gflGetColorAt(const src: PGFL_BITMAP; x, y: GFL_INT32; var color: TGFL_COLOR): GFL_ERROR; stdcall; //ExtrasInfo: Pointer [ERROR]...

Hi,
Have you been able to examine the EXIF data of a photograph obtained with a Nikon camera and check the error that occurs when recording the GPS data?

This new format is based on several photographs in JPG format compacted into a single file. Must be something similar to JPS format. Apparently, this format is used by the FinePix Real 3D camera ( http://www.dpreview.com/news/0907/09072206fujifilmw1.asp ). I will try to get a file in this format. As...

Hi, this time I'm having problems with gflLoadBitmap. 'Access violation at address 00984784 in module libgfl311.dll' Read of address 00000030. The error occurs as above, substituting libgfl2.90 by libgfl3.11 without modifying the source code of the program. I fixed the problem, as the previous case,...

Hello,
Does the library GFL SDK can open and save files in MPF format?

Hi, I changed the constants in the file libgfl.pas: GFL_EXIF_IFD_0 = $0001; GFL_EXIF_MAIN_IFD = $0002; The correct code to save the resolution is: gflBitmapSetEXIFValueRational2(mEXIFData2, GFL_EXIF_IFD_0, 282, 200, 1); // For 200 dpi gflBitmapSetEXIFValueRational2(mEXIFData2, GFL_EXIF_IFD_0, 283, 2...

Hello, I have problems to record the GPS data in a file. I use the following code: var mLoadOption: TGFL_LOAD_PARAMS; mSaveOption: TGFL_SAVE_PARAMS; mOriBitmap: PGFL_BITMAP; mEXIFData2 : PGFL_EXIF_DATAEX; mError : GFL_ERROR ; pq: array[0..5] of GFL_UINT32; LatitudeRef : string; ..... begin ..... gfl...

Hello,
I will continue doing tests to try to determine under what conditions these errors occur.
The program is quite dense and heavy and uses a large amount of memory and variables. I will make a program easier for to try to reproduce the error.

No, apparently I have the problem with gflLoadBitmapFromMemory.

Hello!!!... To save an image in memory I use the code: unit Principal; .... var Imagen1LbStream : TMemoryStream; Imagen1LbExiste : Boolean; ... implementation .... procedure TFormPrincipal.Action37Execute(Sender: TObject); var Size : integer; Mem : PGFL_UINT8; spMem : TGFL_SAVE_PARAMS; ... begin ......

I have solved the problem by declaring the variable in other place of the program.
The variables involved are of type Boolean

Hello!!! I have problems with the new version of the library. My program works correctly with version 2.90 but with the current version seems to have a problem with gflLoadBitmapFromMemory . Apparently, gflLoadBitmapFromMemory modify the content of other variables in the program. This is quite stran...

Thank you very much Dominique. The code works correctly. In Delphi: var pq: array[0..5] of integer; ... begin ... pq[0] := 28; pq[1] := 1; pq[2] := 26; pq[3] := 1; pq[4] := 119; pq[5] := 2; gflBitmapSetEXIFValueRationalArray2(EXIF2,GFL_EXIF_GPS_IFD,2,@pq,3); ... end; In Libgfl.pas: procedure gflBitm...

Hello,
Can you explain me with an example How the function is used to store GPS data?
For example, the latitude 28º 26' 59.55", Can you tell me how to be added to the EXIF information of the picture?

Is it a new version of GFL SDK?
Do you have done tests with the GPS data?
