[Xastir] Raspberry Pi: uk_aprs_maps fail to display

[Paul Kent]

Hi, first post here:
Raspberry Pi model b (256mb)

running xastir v2.0.0 and imagemagick 6.7.7-10 2012-11-24 q16. on a early
model B

I have downloaded uk_aprs_maps.zip from Cross Country Wireless website
extracted them , ran the inf2geo script & indexed the maps in xastir, but
the maps only display as black/tinted garbage.

Can see the maps in all their glory when loaded into imagemagick.
I saw some xastir helpfile references to 'imagemagic support needs to be
compiled in' so tried converting the jpeg to xpm (which is an X pixmap?)
but they still refuse to display.
Also references to ''maps fail to display' problem have been fixed in
version 1.9.x' :?

Xastir downloaded from  recommended (raspbian)  location, not compiled from
source.
Anyone have any ideas why I can only display the worldhi vector map?
