Hi Hans,
I reproduced your error. :( in ms4w 2.2.7
Maybe I missed this before because I was just testing with gmap, and
my bounds didn't go outside the edge of the base data. The AGGA
rendering looks good like you say, and that's what I saw, but with
black outside the base data.
But I don't know why it's happening. I added TRANSPARENT ON to the
OUTPUTFORMAT and it made no difference like this:
OUTPUTFORMAT
NAME 'AGGA'
DRIVER AGG/PNG
IMAGEMODE RGBA
TRANSPARENT ON ////// <- no difference with this ?
END
Also tried to add TRANSPARENCY alpha to all the layers, and no change.
it seems that when the tiles get created from the RGBA pngs, they are
losing the transparency. I'm not sure where this is happening. We
can't change the $GLOBALS['szImageCreateFunction'] back to
"imagecreate" from "imagecreatetruecolor"because this will create an
8bit PNG tile, and you will lose the extra colors in the downgrade.
Although appaently the 8 bit PNG has no problem with retaining
transparency.....
>From your example attachment it looks like maybe your overlays will
suffice with just AGG ? did you try it:
OUTPUTFORMAT
NAME 'AGG'
DRIVER AGG/PNG
IMAGEMODE RGB
END
The tiles will be smaller in size and transparency is retained in my
tests. It's not a real solution, but it might help your situation
while we figure out why AGGA is not right.
