Subject: [Mapit] lat/long
Message-ID: <OE45RLVbNDN4CxpAOAk000100d9@hotmail.com>

Hello,

I have a question about how I can represent lat/long coordinates on a raster image?  Is there an easy way to convert lat/long to x/y?

I followed the instructions to a T and still get the above errors.  Does anyone have any hints or experiences?  Thanks.

which lat/long coordinates belongs to certain point on a rasterimage
depends on the applied geographic projection.

Can you describe your problem more detailed?

Is modpython installed?

It would also help if you tell us which versions of the various programs
that are involved here (apache, modpython, windows), otherwise we
probably can't reproduce the problem here.

Subject: [Mapit] How to produce correct tiles...
Message-ID: <FD68C5A787C0D411A9A100D0B7E0379D5B5100@dts002.datatrak.at>

Dear Sirs,

could you please tell me why I can not produce correct tiles.

I installed demo version of Mapit on WindowsNT Ver.4.0 and it works fine.
Using Imagemagick(Ver. "ImageMagick-win2k.zip"), I converted one jpg file to
eps file (using the command convert europe.jpg europe.eps).
Using python, epscut file and eps file I got following error:
_________________________________________________________________________
C:\Programme\Mapit\src\tools>python epscut europe.eps
gs -sDEVICE=ppmraw -r72 -dNOPAUSE -dSAFER -q  -sOutputFile=C:\TEMP\~154-1

    image.save(outputfile)
  File ".\Image.py", line 686, in save
KeyError: .png

C:\Programme\Mapit\src\tools>
_________________________________________________________________________

I am also using program ghostscript (Ver. gs704w32.exe). After installing I
got two files gswin32.exe and gswin32c.exe. Because epscut looks for gs
program that I don't have on my computer, I renamed gswin32c.exe (command
line version) to gs.exe.

Could you please tell me:
- what is wrong here?
- how to automatically (not to write coordinates for each tile
manually)produce tiles from one eps file that stems from one bigger image
map that has coordinates in WGS84? 
- Where to specify coordinate system?
- Is it possible to insert the coordinates in the program only once and if
it is, where?

Thank you in advance for your (if possible, more detailed) answer.

Gordan Starcevic

That means that for some reason the Python Imaging Library (PIL) doesn't
know about PNG files. 

Which version of PIL do you use? Some older versions had a bug related
to this. MapIt! itself has a workaround for this bug, but epscut
doesn't. You could try to add the line

import PIL.PngImagePlugin

to epscut (a good place would be right after the "import PIL.Image") or
upgrade to a newer version. The bug was fixed in 1.1.2 IIRC.
