[Geomoose-users] Printing wms layers

[Bistrais, Bob]

I copied over the new function and function call in print_util.php.  I
get what's going on there- it's "cutting out" the black portions of the
image, but I'm still getting these in the printable image.

 

One thing I don't understand (and the answer is probably not so simple)-
the map is looking exactly as I'd like in the application- why aren't we
grabbing that image and coping it to the output map file?

Bob,

  I did  a fix some time ago (http://geomoose.org/trac/ticket/108)
regarding using the alpha channel in Print_util.php.  This fix is in
GeoMoose v2.4 so I'm confused...



Best Regards,
Brent Fraser

It sure looks like a problem with the alpha channels.  Doesn't seem to
matter which browser I use, either.

If the quality is different between PNG and GIF you are probably using
PNG24 (as PNG8 and GIF should be identical image wise).

 

My guess is a GD bug dealing with PNG24.  I'm not sure what your options
are, but it sounds like the print.php needs to be rewritten with a more
modern library.

	Looks like I'm using png.  

	 

	One thing I tried was to use gif in the mapbook.xml, for those
WMS layers, but while they displayed alright, the quality was awful.

Yes, the WMS is outputting PNG.  What would be recommended instead?

Something to look at . . . 

  

What is the format of the images from the WMS service? 

  

PNG24 vs other PNG formats have caused problem in cross browser
situations.  Some versions of IE don't like one or the other for
example.

I had brought up this question before but it seems to be happening
again.  I have a few layers that I consume in GeoMoose by WMS.  Some of
these are vecot line layers such as roads.  They work perfectly in
GeoMoose map view.  But when I compose a printable map, these layers
have a black background which obscures other layers and just plain looks
ugly.  If I set the "transparent"  property to false, the black
background goes away, but then I can't see any underlying data.    

  

By the way, I do have control over the WMS services in this case.  I
tried to set Offsite to 0 0 0, but that didn't seem to help either.  The
WMS is at MapServer 6.0.1.  Any suggestions?
