[OpenLayers-Dev] Poor Image Quality

[Bart van den Eijnden (OSGIS)]

OpenLayers uses jpeg by default for WMS layers, so change it in the
constructor of your WMS.Untiled layer:

'format':'image/png', i.e.:

baselayer0 = new OpenLayers.Layer.WMS.Untiled( "Standaard",
               
"http://test.intranet.rijkswaterstaat.nl/services/geoservices/startkaart?",
{layers: 'startkaart', 'format':'image/png', 'transparent':'TRUE'},
{'numZoomLevels': 12, 'ratio':1, isBaseLayer: true} ); 

Also check you have image/png mapped as a mimetype for PNG24 in your
Mapserver MAP file (OUTPUTFORMAT section).

Best regards,
Bart

> I am importing an image as an untiled Mapserver layer into OpenLayers and
it is of extremely good quality but when it shows up in OpenLayers it&#39;s
quality is terrible.The image when viewed through Mapserver is not as good
as the original but it still much better than what it is showing up as in
OpenLayers. I have my Mapserver image format as PNG24.
> Any ideas on what might be causing this and how to fix it?CheersBrad
