done by inscape 0.46 in linux

so my asking is about my problem about compression artifact (maybe?) i'm not specialist in this stuff, so you can watch it here

in png format after exporting there is a lot of lines on the light effect (so the effect of light seems to be not smooth..)
why it's like this?
thank's for help

This effect is called banding. Since PNG is lossless it isn't to blame. The reason for this kind of artifacts is the way Inkscape calculates the gradient's colors - or more precisely: Inkscape only calculates a specific amount of colors (1000 or 2000 or something like that) and it also doesn't bother with dithering.

Currently there are only 2 options: You can either break up the banding with some noise or try a different SVG renderer.

Oh Thnks! I've found the 3rd option is ->smoothing tool in GIMP
so now i belive it looks better =)


I'D SAY MORE LIVELY =)

Glad you were able to solve your problem. Nice work too!

And aho, do you know if that issue is going to be fixed in version .47?

Unfortunately I don't know if anyone is working on this. But I'm pretty sure it's going to be addressed at some point (at least for PNG export).
