Tim is pointing out that if you're viewing an interlaced output image, the first, alternating set of scanlines will be displayed and then your browser will start again at the top of the image, filling in the alternate interlacing lines. This will cause the top of the image to appear complete while the bottom is "blurry". You can see variations on these visual artifacts depending on your browser, and the effect is more pronounced over a slow connection. But if the image still looks blurry at the bottom even after you're certain the image has been completely loaded, then this is not your problem. It's hard to diagnose visual problems in text; can you either post the output image or (preferably) a public URL where the image can be viewed? - Ed Ed McNierney Chief Mapmaker Demand Media / TopoZone.com 73 Princeton Street, Suite 305 North Chelmsford, MA 01863 [EMAIL PROTECTED] Phone: +1 (978) 251-4242 Fax: +1 (978) 251-1396 -----Original Message----- From: UMN MapServer Users List [mailto:[EMAIL PROTECTED] On Behalf Of Lee Keel Sent: Wednesday, January 16, 2008 1:06 PM To: [email protected] Subject: Re: [UMN_MAPSERVER-USERS] mapserver error Timothy, Here are the OUTPUTFORMAT options I have in my map file.

This turns on interlacing and sometimes I see that it takes a few seconds on my mapserver to fully render the image. If you want to prevent this blurring turn that setting off in your Mapfile. ---- Timothy J Nolte - [EMAIL PROTECTED] Associate Network Planning Engineer iPCS Wireless, Inc. 4717 Broadmoor Ave, Suite G Kentwood, MI 49512 Office: 616-656-5163 PCS: 616-706-2438 Fax: 616-554-6484 Web: www.ipcswirelessinc.com -----Original Message----- From: UMN MapServer Users List [mailto:[EMAIL PROTECTED] On Behalf Of Lee Keel Sent: Wednesday, January 16, 2008 11:38 AM To: [email protected] Subject: [UMN_MAPSERVER-USERS] mapserver error Hello list. I am having a problem and it is beginning to look like mapserver is behind it somehow. I am using ms4w 2.2.6 to render postgres data to openlayers. Mapserver is configured to use IIS\CGI instead of apache. I am actually having 2 problems, but I am not sure that they are not related. One problem is that sometimes the server just isn't returning any data for different layers to OpenLayers. I have talked extensively with the OL guys and have come back to the fact that if I take the URL that is requesting the information from mapserver, then I get: "The specified CGI application misbehaved by not returning a complete set of HTTP headers." The most consistent way I can reproduce this is to zoom in real close. The second problem I am having is that when I am getting layer images back, they are blurred on the bottom portion. It looks like someone took a cloth and just wiped a whiteboard. I am about 5 days late on a deadline to have this up and running, so I am open to try any suggestions that someone may have. Thanks in advance, Lee
