EXIF - GPS

Post by madiazg »

Hello,
I have a problem to store in a photo the GPS data.
Reference Latitude (North / South) or the length of reference (East / West) I do not have problems because they are datas the ASCII type:

Code: Select all

gflBitmapSetEXIFValueString2(EXIF2, 16, 1,PChar(LatitudeRef));
I have problem with the latitude and longitude which, according to information I found on the Internet, are data type Rational:


The latitude is expressed as three RATIONAL values giving the degrees, minutes, and seconds, respectively. When degrees, minutes and seconds are expressed, the format is dd/1,mm/1,ss/1. When degrees and minutes are used and, for example, fractions of minutes are given up to two decimal places, the format is dd/1,mmmm/100,0/1.
Tag = 2 (2.H)
Type = RATIONAL
Count = 3
Default = none


For example, the latitude 28º 26' 59.55", Can you tell me how to be added to the EXIF information of the picture?

Regards...
Miguel Angel

Hello Pierre,
Do you have intentions to add this feature in future version of GLF SDK?
