Warning
From January 2019, the functions for managing Google Picasa photo albums will no longer be available. Indeed, the corresponding Google API is no longer available from January 2019. It is necessary to use "Google Photo API"..
This new API is accessible via AuthIdentify and HTTP requests. See https://developers.google.com/photos/library/guides/overview for more details.
The gglEXIFTag type is used to describe and modify the EXIF tags associated with a photo found in a Google Picasa album. The characteristics of this type of variable can be defined and modified by several WLanguage properties.
This type of variable is used by the gglPhoto variables.
Note: See Declaring a variable for more details on the declaration of this type of variable and the use of WLanguage properties.
Example
// Connection to Google
Cnt is gglConnection
Cnt..Email = "vince@gmail.com"
Cnt..Password = "azerty"
Cnt..ApplicationName = "MyApp-01"
IF GglConnect(Cnt) = False THEN
Error(ErrorInfo())
END

// Retrieve the array of available albums
arrAlbum is array of gglAlbum
arrAlbum = GglListAlbum(Cnt)

// Retrieve all the photos from the first album
// (the meta-data only)
GglFillAlbum(Cnt, arrAlbum[1], gglWithImage)

// Browse the photos
MyPhoto is gglPhoto
FOR EACH MyPhoto OF arrAlbum[1]
Trace(MyPhoto..EXIFTag..ImageUniqueId)
END
