Re: [Gtk2hs-users] Example of using pixbufSave

[koral <ko...@ma...>]

Hello,

Since gtk2hs 0.13, every function that used to be fed with a String, can now be fed with either a String or a Text.
This was implemented using the typeclass GlibString that has 2 instances: String and Text.
In your case, GHC was unable to deduce alone which one to use for the last argument of pixbufSave: the value [] doesn't help disambiguating between [(String, String)] and [(Text, Text)].
To fix it, simply write the type explicitly:

    pixbufSave pb toPath jpegImageFormat ([] :: [(T.Text, T.Text)])

Regards.
