Multiply Blend Mode in .sif Export

Postby d_g_ » Wed Mar 25, 2015 9:12 am

I've noticed some strange behavior when saving in Synfig format (.sif) in version 0.91.

Any object that is using a Multiply blend mode in my svg becomes not 1 but 2 inline canvases (linked) in the Synfig version. One of them has blend mode Multiply, but the other has blend mode Behind. I can't figure out why it would do that.

It might have something to do with the algorithm for the Multiply blend mode is a little different in Synfig (usually it ends up lighter than the Inkscape equivalent.) But putting the Behind blend mode doesn't really do anything to help that.

I've been changing the clone's blend mode back to Multiply in Synfig, and then setting the "Amount" parameter for both to 0.9. This seems to give me results that are pretty consistent with what my original SVG looked like in Inkscape.

By the way, I'm using Synfig 1.0 RC-1, so it's possible that the integers used for the blend method parameter are different from previous versions.

Anyway, I wanted to get some other opinions on this before I report it as a bug. It could be that this behavior is intended.

Thanks!

Hello,
I'm not sure to have seen that behaviour.

Could you post a sample file?

Keep in mind that before exporting to synfig, there is an extension that "prepares" the inkscape's svg design. it's better to transform all to paths, even the texts. There are a lot of features that synfig's exporter doesn't know how to translate from svg to sif

I've noted also that it's better to put your paths in svg layers, so Synfig can group them
If you have problems:
1.- Post a sample (or samples) of your file please.
2.- Please check here:
