A simple map viewer

Hi, all,

Recently, I developed a simple map viewer for my Zaurus with GTK+.

Because most map image file is very big, from several MB to tens
MB, it is very inconvenient to view map with ordinary image viewer,
especially for embedded system like PDA and mobile phone.

This program is developed to facilitate map viewing, the basic idea
behind it is:

1. The big map image file is splitted into many small image files,
  loaded on demand to reduce memory requirement.
2. The big map image file is pre-scaled too, because scaling a big
  image file is also a memory/CPU hungry task.

Some other useful feature for a map viewer is also provided. For
example, personal marks can be added to a map. A map making
tools is also provided to facilitate splitting and scaling the big map
image file.

The source code of this program can be found below:

Best Regards,
Huang Ying
