About new problems:
1) Have you defined the various characteristic of your PNG output?
You should try with this (for PNG):
OUTPUTFORMAT
NAME png
MIMETYPE image/png
DRIVER GD/PNG
EXTENSION png
IMAGEMODE PC256
TRANSPARENT FALSE
END*
*put this in the mapfile
2) For gdaltindex.exe I don't know: I've never used it, but try looking
deeper in mapfile definition, maybe you must declare something different
for using it.
Hope this helps.
Bye

Hi,
thanks for your answer. I was able to implement one of the pictures into a new layer like you described. Two new problems turn up.
1) The image quality is really bad, the picture gets all reddish and yellowish
and seems to loose pixels. I use PNG as format for all my maps. All the other
(polygon) look ok this way. I tried PNG24 but I'm loosing transparency there.
Is there another recommendable image-format? or what can I do to improve the
picture quality in mapserver?
2) I have 80 orthofotos. Since I don't want to add a layer for each one I
created a tileindex with gdaltindex.exe ... the created dbf file contains one
column called LOCATION and has all the name of my jpegs in it but when I use it
in mapserver the screen stays white, no pictures show up. Anyone having ideas
on this?
Thank you
Janosch

Betreff: Re: [mapserver-users] JGW+JPG -> TIFF
Hi.
If you create a layer in the mapfile, with DATA set to your-raster.jpg,
it automatically reads .jgw (it must have the same name of the jpg file)
and users its informations for georeferencing it. Specify also TYPE
raster and if you want MIN/MAXSCALE.
If you prefer tiff file, you must convert jpg in tif by means of a
graphic editor and then translate .jgw in .tfw. It could request not
only renaming the file, but also modify some coefficients defined inside
the .jgw file (open it with notepad, it is simple text).
Hope this helps.

Hello,
I have a set of orthophotos which are saved as JPG. Each picture has a
corresponding JGW file. Can I somehow implement these into a mapserver
layer? Or do I need to create georeferenced tiffs? If so, how can I
combine the JGW and JPGs into a tiff?
Thank you
Janosch
