Re: [mapserver-users] PIXMAP Symbols png and jpeg not recongnized

Any chance there are multiple versions of libpng and libjpeg?

Re: [mapserver-users] PIXMAP Symbols png and jpeg not recongnized

[Flavio Hendry]

Hi Steve

Thanks for the answer ... the issue we see, is that png and jpeg do not 
work as PIXMAP symbols - such as the below throws an error:


SYMBOL
 NAME "cablecar"
 TYPE PIXMAP
 IMAGE 'symbols/cablecar.png'
END

The error it throws:
"Image handling error. Failed to draw layer named 'Aerialway Points'."

Using TYPE PIXMAP with gif or TYPE SVG works ...

We have:
- libpng-dev1.6.34
- libjpeg-dev 8c

Re: [mapserver-users] PIXMAP Symbols png and jpeg not recongnized

[Lime, Steve D (MNIT)]

The warnings look legit. I did a quick search and neither of those global 
variables are being used anywhere in the source (PNGsig is actually defined 
twice in 7.4, once in mapsymbol.c and again in mapogcsld.c). I assume that 
means they can be removed and/or the warnings can safely be ignored. Perhaps 
your compiler is just newer and therefore smarter?

Are you seeing issues beyond the warnings?

Hi all

Never had a problem with PIXMAP symbols, this is on a new install (tried
to recompile several times and several versions, Ubuntu 18.04.3 LTS).

We see the following that  might cause the problem, any idea???

[ 21%] Building C object CMakeFiles/mapserver.dir/mapsymbol.c.o
/tmp/mapserver-7.4.2/mapsymbol.c:52:28: warning: ‘JPEGsig’ defined but
not used [-Wunused-const-variable=]
  static const unsigned char JPEGsig[3] = {255, 216, 255}; /* FF D8 FF
hex */
 ^~~
/tmp/mapserver-7.4.2/mapsymbol.c:51:28: warning: ‘PNGsig’ defined but
not used [-Wunused-const-variable=]
  static const unsigned char PNGsig[8] = {137, 80, 78, 71, 13, 10, 26,
10}; /* 89 50 4E 47 0D 0A 1A 0A hex */


THX.
