Hello,

I’m reading album art back from my iPod over the serial port. It is  
coming back as 100x100 RGB 565, little endian. Is it possible to  
display this data with Ruby/Gtk2 ? I’ve tried to create pixmaps, but no  
luck. I’ve attached a raw dump of an album cover art.

Thanks in advance,

Matt

Hi,

does anyone know how I can load the Gnome desktop’s  
file icons into my app? I have a directory tree  
browser and I would like the icons in it to be the  
same one’s as in e.g. Nautilus.

thanks  
Dan

I would use GnomeVFS to get the mimetype and then replace “/” with “-”  
to get the icon name and try loading it with  
Gtk::IconTheme.default.load\_icon

Hi,

your data is not vallid. It has a size of 19980 Bytes.

An Image of 100x100 RGB 565 would have a size of 20000 Bytes  
(100_100_2).

Cheers
