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?

Re: Multi-Picture Format

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...

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,...

Re: Problems recording GPS data

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...

Re: Error in gflLoadBitmapFromMemory ?

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.

Re: Error in gflLoadBitmapFromMemory ?

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