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, mLoadOption, lInformation); // Carga una imagen en Memoria

    gflGetDefaultSaveParams(mSaveOption);
    mSaveOption.Flags := GFL_SAVE_REPLACE_EXTENSION;
    mSaveOption.Flags := GFL_SAVE_ICC_PROFILE;
    mSaveOption.FormatIndex := 0;
    mSaveOption.Quality := 50;
    gflSaveBitmap(PChar('prueba.jpg'),mOriBitmap,mSaveOption);

If I load the EXIF data and then I save them

Code: Select all

    gflLibraryInit();
    gflGetDefaultLoadParams(mLoadOption);
    mLoadOption.Flags := GFL_LOAD_READ_ALL_COMMENT;
    mLoadOption.Flags := GFL_LOAD_METADATA;
    mError := gflLoadBitmap(Pchar(FileName1),mOriBitmap, mLoadOption, lInformation); // Carga una imagen en Memoria

//EXIF 2
    mEXIFData2 := gflBitmapGetEXIF2(mOriBitmap);

    gflBitmapRemoveMetaData(mOriBitmap);
    gflBitmapSetEXIF2(mOriBitmap,mEXIFData2);

    gflGetDefaultSaveParams(mSaveOption);
    mSaveOption.Flags := GFL_SAVE_REPLACE_EXTENSION;
    mSaveOption.Flags := GFL_SAVE_ICC_PROFILE;
    mSaveOption.FormatIndex := 0;
    mSaveOption.Quality := 50;
    gflSaveBitmap(PChar('prueba.jpg'),mOriBitmap,mSaveOption);
    gflFreeEXIF2(mEXIFData2);

there are errors in the following fields:

x Resolution
y Resolution
Exposure Time
Focal Length

Curiously, if I load the previously saved image and I save it, EXIF data is stored correctly as in the original image. That is, the second copy retains the EXIF data correctly.

This error does not occur with other camera models
