[mapserver-users] Layer opacity not working

[Rahkonen Jukka (MML)]

Hi,

I can confirm with Linux and Mapserver 7.0.2.  I found also an easy workaround: go back to deprecated style - opacity

          STYLE
            OUTLINECOLOR "#000000"
            COLOR "#98C06B"
          OPACITY 50  
          END

Aihe: Re: [mapserver-users] Layer opacity not working

I've created a small test case to reproduce (and included the commands to run) and filed a ticket: 
https://github.com/mapserver/mapserver/issues/5343

Also, I've noticed that when running the GetMap request at the commandline, 7.0.2 returns this odd error message (works fine with 7.0.1):

*** BUG ***
In ???: The expression bits == NULL || (rowstride_bytes % sizeof
(uint32_t)) == 0 was false
Set a breakpoint on '_pixman_log_error' to debug
