about the padding part in the displayed map

[王连波]

I download and configure ka-map according to my private situation, everything goes well except that there are some padding parts (I call them shadows) in the displayed image .I just test to produce an image through a mapfile with only one layer(just a tiff picture with its geoinfo file .tfw). It is ok to display the image, but the color of most parts in the image is changed from original ,also many shadows of different colors appear at the border of the image. What is the problem? Hope someone can help me .
Maybe it is due to the tile parameter ,but I have tried to change them and the issue is still there.

Joel:

hello, the problem you describe, I think it is due to the
configuration of OutputFormat, if you want your layers
raster display as the original, then use the
RGB PNG format, you must configure the file
"config.php".
greetings!

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!

Hi from Bolivia, i have read your problem, the council i give you
that utilizes the JPG format, with mode=RGB, don't forget, who always have to
remove the temporary directory, where the temporary images, for instance:

OUTPUTFORMAT
NAME jpeg
DRIVER "GD/JPEG"
MIMETYPE "image/jpeg"
IMAGEMODE RGB
EXTENSION "jpg"
END
