EXIF VALUES

Post by CONFAIS »

Hi
I use GFLSDK Version 2.90 with visual basic.
I can read and write IPTC values.
I can read EXIF values but I can't modify them using DLL functions.
Could you send me a visual basic example to update EXIF values please ?

Many thanks.

Hi Pierre,

Thanks for your answer.

What about following functions :
gflBitmapGetEXIF2,
gflBitmapSetEXIFValueString2,
gflBitmapSetEXIFValueInt2,
gflBitmapSetEXIFValueRational2 and
gflBitmapSetEXIF2

I can find them in library libgfl290.dll.

Many thanks.

I'm using the same version of GFLSDK with Visual Basic. Can you show me an example of readig IPTC and EXIF data under VB? There's no example in the distribution, and I can find no obvious way of porting the required structs to VB for using functions such as gflLoadEXIF and gflLoadIPTC.

Thanks in advance!

Edgardo.
