Processing a map file with use of mapscript_csharp.dll (version 7.0.1) and map contains a few WMS HTTP layers and some are local shapefiles.
After upgrading from Mapserver 7.0.1 to latest version 7.0.4 by copying necessary (e.g.cgi-bin) dll's to my application bin and correct versions of libmap/mapscript dll (concerning oracle) I get an error when executing the map.draw() function (using the same map as with 7.0.1):
"drawGDAL(): Unable to access file. GDALDatasetRasterIO() failed: libpng: bad parameters to zlib"
[System.ApplicationException]: {"drawGDAL(): Unable to access file. GDALDatasetRasterIO() failed: libpng: bad parameters to zlib"}
Data: {System.Collections.ListDictionaryInternal}
HelpLink: null
HResult: -2146232832
InnerException: null
Message: "drawGDAL(): Unable to access file. GDALDatasetRasterIO() failed: libpng: bad parameters to zlib"
Source: "mapscript_csharp"
If I remove the HTTP WMS layers from my map file it works.
Could someone explain what I am missing and/or what file could not be accessed?
If any other info needed, let me know.
