Displaying RGB 565 data

Desktop Ruby-Gnome 2
1

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
(1001002).
