I've started looking at the WMS CITE tests, but I havent been able to
get a single test to run!
It appears there's something wrong with the images produced by
geoserver.
1. JPEG seems to be broken (there's two implementations)
A) com.sun.media.imageioimpl.plugins.jpeg.CLibJPEGImageWriter --
this JAI IO doesnt fails completely:
javax.imageio.IIOException: The provided image cannot be encoded
using: com.sun.media.imageioimpl.plugins.jpeg.CLibJPEGImageWriter

at
org.vfny.geoserver.servlets.AbstractService.doGet(AbstractService.java:247)
B) com.sun.imageio.plugins.jpeg.JPEGImageWriter
(you have to call this by hand in JAISupport#encode() - use the
2nd writer given by the iterator)
This one writes an image, but it isnt renderable in Modzilla:
error message: The image
"http://localhost:8080/geoserver/wms?VERSION=1.1.1&REQUEST=GetMap&LAYERS=cite:BasicPolygons&STYLES=&SRS=EPSG:4326&BBOX=-1,-1,1,+1&WIDTH=400&HEIGHT=400&FORMAT=image/jpeg"
cannot be displayed, because it contains errors.
I open it up in an image viewer program, and it looks horrible!
2. The PNG and GIF producers seem to work (these are the only ones I
could get to work)
Unfortunately, they dont give the same image!!
Compare the two image's I've attached - look at the very bottom of
the image. The GIF's image clipped by about 5 pixels.
3. The capabilities says it supports:
<Format>image/x-portable-graymap</Format>
<Format>image/jpeg</Format>
<Format>image/svg+xml</Format>
<Format>image/bmp, image/x-bmp, image/x-windows-bmp</Format>
<Format>image/x-portable-pixmap</Format>
<Format>image/x-portable-anymap</Format>
<Format>image/png</Format>
<Format>image/jp2</Format>
<Format>image/jpeg2000</Format>
<Format>image/x-png</Format>
<Format>image/tiff</Format>
<Format>image/vnd.wap.wbmp</Format>
<Format>image/x-portable-bitmap</Format>
<Format>image/gif</Format>
But most of these do not produces images or create invalid images
ie. image/bmp - "There is no support for creating maps in
image/bmp format"
image/vnd.wap.wbmp - "Only integral single-band bilevel image
is supported."
image/tiff - gives the same error as the CLibJPEGImageWriter
4. DefaultRasterMapProducer#produceMap() has this:
BufferedImage curImage = new BufferedImage(width, height,
BufferedImage.TYPE_INT_ARGB);
I tried a TYPE_4BYTE_ABGR but it didnt seem to change anything.
Any help on this would be much appreciated!
