Specular Exponent limited to 50 in Specular light Filter in 0.48

[ivan louette]

While in 0.47 you can go up to "100" in Specular Lighting Specular exponent I noticed that in 0.48 Filters Editor is limited to 50

Even if 8 bit per channel color depth gives some 3D aliasing effects at high values it seems to me that there is no practical reason to impose this limit.

0.48 and 0.48 devel 10019 on kubuntu 10.04

Tested on OS X 10.5.8 (GCC 4.2.5), locale en_US.UTF-8:
Inkscape 0.47: 'Exponent' is limited to 128.0
Inkscape 0.48.0: 'Exponent' is limited to 128.0
Inkscape 0.48.1: 'Exponent' is limited to 128.0
Inkscape 0.48+devel r10032: 'Exponent' is limited to 50.0

AFAICT this is a regression in current trunk only.

Note: I don't see the limit 100 in older versions either (it's 128.0 on my system - filter primitive 'Specular Lighting > Exponent'). The 'Specular Lighting > Constant' setting on the other hand is limited to 100.00 in older versions, and 5.00 in current trunk.

Seems to have been an intentional change:
