[ka-Map-users] about the padding part in the displayed map

[王连波]

Firstly, thanks to anybody who helps me and I am so glad to tell you that it
gets better when I changed the mapfile and config.php to enable png24
OutputFormat. I do it like this :
1)in the mapfile ,add these lines:
OUTPUTFORMAT
NAME png
DRIVER "GD/png"
MIMETYPE "image/png"
IMAGEMODE RGB
EXTENSION "png"
END
2)in the config.php, I changed the default PNG OutputFormat to PNG24

However, it's still not so good like I have expected. First, there is still
shadows at the bottom of the map. Second, the colors of some part is a
little different from the original picture. I have tested that when I
changed
PNG to JPEG in both mapfile and config.php , the shadows at the bottom
disappeared while the map became very dazzling with something like colorful
pepper and salt noisy. It is the same with DITHERED .
The picture which I use in the mapfile as a raster data is from Google
Earth. It is about 100M and its format is JPEG (maybe it is why the bottom
shadows disappear when I changed the OutputFormat to JPGE ,I guess). Now I
do not know what I should do to make the map  looks  better in  ka-map.
THX  in advance  for  any help!
