[mapserver-dev] 5.4 beta-1 tomorrow?

[Tamas Szekeres]

Steve,

I'd be in favour of fixing the division by zero problem I've reported
previously (see below) before the beta.
However I'm waiting for someone who confirms that there would be no negative
impact on setting the symbol sizex/sizey to 1 instead of 0 by default.

Best regards,
Tamas

Hi Devs,

I find in many places in the code the following fragment:

scale = size/symbol->sizey;

without actually checking the value of symbol->sizey which may be zero
eventually. This causes me unexpected problems, like for example a premature
termination of the application during the pdf output.
How about setting the symbol size to 1 instead of 0 in initSymbol to prevent
from this problem?

Best regards,

Tamas
