[mapserver-users] problem displaying mask
I'm trying to display a water mask as all black. Along the edge of the mask a set of lighter colored pixels appears when zoomed out. It appears this is from resampling the data. I have OFFSITE set and I have NO_DATA set in the GeoTIff yet something is ignoring these during render. Any suggestions? I've attached an image. Black is water white (which is set to transparent) is land. I assure you the lighter pixels are not beach/coastline. I'm using a 5.6.7. -ethan This electronic communication and any attachments may contain confidential and proprietary information of DigitalGlobe, Inc.

Re: [mapserver-users] Hindi and Thai text rendering (thomas bonfort)
Some more info, this issue has the same symptoms as we have. The initial description and the correct.png and wrong.png show the same rendering issue we are seeing. http://code.google.com/p/android/issues/detail?id=4153 We are still investigating this but at the moment do not even know what those parts of these characters are called so it's tricky to find information. Can anyone on the list read these characters?

Is there any way you could provide an image showing a Hindi translation for Mexico City from your map? This way I can match characters that I know are not rendering properly on my side.

I have just had a look at 0.19.4 and 0.19.5 and I am not sure how to build them, there does not appear to be build instructions in them or a configure script.

Your mapfile definitions are correct to activate this (i.e. it includes an LABEL.ENCODING parameter). I'll leave it up to you to confirm that the image sample I sent you is correct or not. If so, check that you have configured your mapserver with fribidi enabled and uptodate (the supplied image was rendered with 0.19.2 . some stable distros use a very outdated fribidi version, so you might need to upgrade manually) . If not, you can try with a bleeding edge fribidi (0.19.5 was released a few days ago), and/or report the issue or find help from the fribidi project directly. please report back with your findings. regards, thomas On Sun, Dec 16, 2012 at 2:31 AM, Peter Mallen peter.mal...@airborne.aero wrote: Hi Thomas, Here is a link to a png Image I have created of using the simple Map File I provided in the previous postings, this is exactly how the Hindi text is rendering in Map Server: http://www.maplusplus.com/images/Hindi_Incorrect.png It is appearing incorrectly and should appear as shown in this link to Google Translate: http://tinyurl.com/cqlymgy I am not sure if the Hindi you have provided is displaying correctly, although it appears to be similar to what I looked up in Google Translate.

Re: [mapserver-users] JPEG and OVERSAMPLE_RATIO
Hi, Thanks to Thomas, the problem has been solved by removing an OFFSITE parameter configuring the layer (http://mapserver.org/en/mapfile/layer.html). With the following layer configuration: PROCESSING RESAMPLE=AVERAGE PROCESSING OVERSAMPLE_RATIO=16 the visual quality of the produced image is very good (for the PNG and JPEG format).
