Rendering: black background with FORMAT!=PNG inside ajaxmappane.templ

[ulysess]

I'm using WindowsXP and MapguideOS 2 RC1, but the problem is the same in Beta. Not tested with 1.2.

When I change in the url the variable FORMAT={GIF | JPG | JPEG} (another different to PNG), the map show the background in black. Screenshot included.

Can someone check to see if this happens in MGOS 1.2 as well? Thanks, Tom

Tested. This doesn't happens with the MGOS 1.2.

Sometimes when I use the zoom in/out, show a black background while is loading, but finally show the map (1.2)

I use WinXP+IIS+PHP with default installation on both cases (1.2 and 2.0).

Tried with RC2. The same problems.

Tried with RC3. The same problems. I think maybe is a problem with the transparent background color.

Doesn't tested with RC4 yet, but I've tried to change in bin\serverconfig.ini the renderer from AGG to GD, and with GD everythings works fine (PNG, JPG and GIF).

So the problem is the AGG renderer.

Fix submitted for 2.0.x stream in  http://trac.osgeo.org/mapguide/changeset/3028 and for trunk in  http://trac.osgeo.org/mapguide/changeset/3029

Support for GIF has been fixed and PNG8 support has been implemented. The following formats will now work in ajaxmappane.templ:

PNG:  32 bit PNG with alpha
PNG8: 8 bit indexed color PNG with transparency support
GIF: 8 bit indexed color GIF with transparency support
JPG:  24 bit JPG image with no transparency

Also added experimental PNG8 tile support for 2.0.x stream  http://trac.osgeo.org/mapguide/changeset/3030 and trunk  http://trac.osgeo.org/mapguide/changeset/3031

Tiled images can now be rendered and served as:

PNG:  32 bit PNG with alpha
PNG8: 8 bit indexed color PNG with transparency support
JPG:  24 bit JPG image with no transparency

The MapGuide Server renders all tiled images in the same format. This is controlled by the serverconfig.ini file "ImageFormat" parameter.

ImageFormat = PNG8

will cause all images to be rendered and served as PNG8.
