Re: [mapserver-users] 16 bit PNG or 16 bit jpeg output

[Rahkonen Jukka]

Hi,

Could it be possible for you to use WCS 1.0.0 for avoiding the multipart thing?

Hello,

I am trying to output a single band 16bit png (or jpeg) output from a Mapserver 
WCS service.

I have tried the following output formats:

OUTPUTFORMAT
NAME jpeg
DRIVER "GDAL/JPEG"
MIMETYPE "image/jpeg"
IMAGEMODE INT16
EXTENSION "jpg"
FORMATOPTION "QUALITY=85"
 END

OUTPUTFORMAT
NAME GDALPNG
DRIVER "GDAL/PNG"
MIMETYPE "image/png"
IMAGEMODE INT16
EXTENSION "png"
FORMATOPTION "FILENAME=result.png"
  END

When I try different IMAGEMODEs, I get the correct results, but for some 
reason, INT16 does not work. I looked through the mailing list and I noticed 
that this question has been asked before:

http://osgeo-org.1803224.n2.nabble.com/16-Bit-PNG-Output-td6249725.html
http://osgeo-org.1803224.n2.nabble.com/Using-a-16-bit-per-band-PNG-image-td2490088.html

I tried looking for a ticket in Trac, but I had no luck. Am I doing something 
wrong? Perhaps I could accomplish this somehow with a custom gdal driver?

Also, a side question, if I wanted to make sure the replies from my WCS 
getcoverage calls were not multipart (I am just interested in the binary 
output), is there some mapserver-specific setting I can use to just get that 
image as a reply instead of the accompanying xml files?

Thanks!

[mapserver-users] Re: Mapserver + regex license

[jbicik]

Dear All,

Thank you very much for your replies and clarifications. Your are right that
Mapserver on its own does not use GNU regex. The MS4W windows build seems to
use it
(http://maptools.org/ms4w/index.phtml?page=README_INSTALL.html#mapserver-build-environment).
I might get in touch with the MS4W maintainers to clarify their license: "In
general MS4W is licensed under an MIT/X style license".

As you have all pointed out, Mapserver for Windows can be quite easily built
with other non-GPL implementations of regex. I did not realise this from the
Build instructions on Mapserver's website
(http://www.mapserver.org/installation/win32.html). However, the nmake.opt
file gives a hint that this can be done. I was successful with the PHP 5.3.1
regex (http://museum.php.net/php5/php-5.3.1.tar.bz2). As someone mentioned
in the dev mailing list recently, the regex from PHP 5.3.9 cannot be used so
easily since the latest regex code includes some other PHP-related files. I
have not yet tried the PCRE implementation Norman kindly suggested in his
reply.

Frank, I very much appreciate your explanation of the requirements of GPL v2
license. This sounds very reassuring for the commercial application I had in
mind!

All the best, Josef

[mapserver-users] Labeling behavior at the edge of image

[Jackey Cheung]

Hi all,

I've met an issue during my work. There is a polygon right at the edge
of an generated image. By setting position to auto, the label is
rendered, shifted a little bit off. It's as expected I would say.
However, a question arose immediately, what happen to the label of the
other part of the same polygon in the tile right next to this image?
Answer is that it's not render, no label to the other part. It seems
reasonable too. But it does seems a bit odd to viewers, since after
tiles are shown on a browser tile by tile side by side. No one will
notice that there is the edge slicing the polygon right into two
parts, and the label is shifted off from the center of the polygon.
So, if I would like to have the label sits right at the middle
(position cc) of the polygon, then what?

Not sure if it can be achieved. I've tried allowing partial label, but
doesn't seem working. Anyone have any idea?

RE: [mapserver-users] Labeling behavior at the edge of image

[Lime, Steve D (DNR)]

You can use the "label_no_clip" (I think that's right) PROCESSING parameter to 
force label position to be computed on the untransformed geometry. This results 
in a stable position regardless of scale or map extent. 

You can also use the label parameter MINFEATURESIZE to limit the size of the 
features being labeled. Its value is given in pixel and for polygons its 
compared against the narrowest portion of the computed bounding box for the 
feature.

Steve

[mapserver-users] Php MapScript processquerytemplate

[Lucas Middleton]

Hello,


I am using Mapserver 6.0.1 and am having some trouble understanding exactly
how the method processQueryTemplate works in php mapscript.

I am unable to get processquerytemplate to return anything even though I
have verified that the proper template is set in my classObj object.

I threw together a quick query script with direct paths to my mapfile and
the Expression for a feature that I know to exist plugged in. I am receiving a 
query result
but processquerytemplate still isn't giving me anything back...

The documentation does not go in to much detail and I was hoping someone
could provide a more detailed explanation of what is supposed to be passed
to processquerytemplate and what is returned

Any advice would be greatly appreciated!

Thanks,

-Luke

Hi List,

is it possible to use a  template with a WFS server to customize the

[mapserver-users] MS4W with an external Apache

Re: [mapserver-users] MS4W with an external Apache

[Carlos Ruiz]

Juan,

Lo que quiero entender es que tienes un servidor de producción que tiene 
instalado MS4W y además otra versión de Apache.

Nunca he intentado hacer lo que comentas. Supongo que tienes que igualar de 
alguna manera las configuraciones del archivo httpd.conf de la instalación de 
MS4W (módulos instalados, variables de entorno, etc), que se encuentra en 
/ms4w/Apache/conf.


Saludos desde México


Juan,

I want to understand that you have a production server which has MS4W installed 
and also another Apache version.

I've never tried to do something like that. I suppose that you have to match 
the MS4W httpd.conf configuration file (loaded modules, environment variables, 
etc) located at /ms4w/Apache/conf.
 


Cheers from México

Hi Giovanni,

I do not use the PHP MapFish. I'm only working with OpenLayers and MapFish
JS.

Carlos,

The production server is that have the Apache 2.2 only. But in development
I've used MS4W. In this case, the apps folder is outside of the Apache
folder and the configuration seems so difficult.

I assume you mean WCS 2.0 and that you are referring to the MEDIATYPE

Re: [mapserver-users] 16 bit PNG or 16 bit jpeg output

Hi,

if you omit the mediatype parameter with version 2.0 you definitely get
back only the binary output as requested in the format parameter. In WCS
1.1 afaik you always get back a multipart response and in WCS 1.0 always
only the binary.

Re: [mapserver-users] Can't get 8-bit palette output

[Jan Hartmann]

I see. Just for curiosity: why was png/gd dropped and wouldn't it be an 
idea to add an option to generate automatically a palette for png 8? 
Paletted output is still very useful for choropleth maps.

GD is for GIF only in 6.0+. To get paletted output you can set:

-IMAGETYPE GIF (GD-based)

-IMAGETYPE PNG (AGG 8-bit)

-Setup an output format with like Rich G. mentioned

-Setup an output format that forces use of a pre-defined palette

OUTPUTFORMAT

Happy New Year, all.

I'm porting my applications from MapServer 5.7 to 6.0.1, and I am 
unable to get 8-bit palette output. The MapScript commands are:


$oMap->outputformat->set('driver','GD/PNG');
$oMap->outputformat->set('imagemode',MS_IMAGEMODE_PC256);

which give me the following warning, and no image:

*Warning*: mapObj::draw() [mapobj.draw 
]: 
[MapServer Error]: agg2CreateImage(): AGG2 driver only supports RGB or 
RGBA pixel models


I tried every combination I coud think of, with GIF and GDAL, and got 
always the same result. MapServer was compiled with gd-support:


MapServer version 6.0.1 OUTPUT=GIF OUTPUT=PNG OUTPUT=JPEG 
SUPPORTS=PROJ SUPPORTS=AGG SUPPORTS=FREETYPE SUPPORTS=ICONV 
SUPPORTS=WMS_SERVER SUPPORTS=WMS_CLIENT SUPPORTS=WFS_SERVER 
SUPPORTS=WFS_CLIENT SUPPORTS=WCS_SERVER SUPPORTS=THREADS SUPPORTS=GEOS 
INPUT=POSTGIS INPUT=OGR INPUT=GDAL INPUT=SHAPEFILE


Any idea, someone?

Re: [mapserver-users] 16 bit PNG or 16 bit jpeg output

[Ragi Burhum]

Hello Jukka and Stephan,

Thank you a lot for the pointer. Yes, version 1.0.0 definitely does the
trick and I will use that instead. I got a big confused with the
documentation and it was not too clear to me that was the behavior. Thank
you!

As far as my original question for 16bit png (or jpeg) output, is there
something that can be done about that?

The tiff output files I get are too big for such a small area and it makes
unusable for mobile devices.

Thanks again,

- Ragi

Re: [mapserver-users] 16 bit PNG or 16 bit jpeg output

[Rahkonen Jukka]

Hi,

I believe you can configure Mapserver to create also compressed tiffs. There 
are many alternatives to choose on the gdal driver page 
http://gdal.org/frmt_gtiff.html

Re: [mapserver-users] Labeling behavior at the edge of image

[Jackey Cheung]

Hi Steve,

Thanks for you promptly reply. I've definitely try "label_no_clip"
out. However, I don't think the MINFEATURESIZE if for me. The polygon
as a whole is big enough for labeling, the problem is just that it's
sliced into two parts. Having a min size limit on it may render the
label gone at the edge, which is not the desire result.
