Title: Bend group with gradients
Post by: Janne on January 21, 2015, 12:17:23 PM
I don't know if this is the right place to ask for hep but I have tried to bend a rough drawing of a bamboo stick without luck.
How do I do this?

I have tried in very different ways but either are the gradients destroyed or the hole thing distorted.

Oh gosh!  I just answered your question on InkscapeForum.  I appreciate you posting here, but it's probably better not to post the same message in both forums, just because it could be so confusing.  In this case, with these 2 forums, it's probably not so bad.  But if they were unrelated forums, you could get conflicting replies, and one forum wouldn't know what you did under instructions from the other forum, and all that.

I don't know an easy answer.  One thing I didn't say in the other topic, is that with vertical patterns, there is a check box for it, in the LPE.  Whenever I use those vertical checkboxes, they mess up the whole thing.  But I learned if I turn the vertical drawing on it's side, then apply the LPE, it sometimes works better.  Then later, I just flip it back upright.  I tried that with your drawing, but it didn't work.  I'm not sure how you managed to apply the LPEs with gradients, like you did, though.

But we can still use this message to help build up the forum.  Not that I'd want to do this on a regular basis.  But since the question is already posted, once we find a good answer, we'll copy it over here, and it can still help other people.

Thank you again, Brynn - I'll not double post again!
Yes, the LPE messes things up - I tried different options - also visiting the Extensions area :)

My 'bamboo' was a simple trial - an object with a gradient, duplicated and grouped and now I want to bend it.
Actually I think that I could use Lazur's pencil-model?

Hhmm, Lazurs' pencil model .... which I think is using markers to make a curved gradient.....  No, I don't think that would work.  Unless I don't understand what you want to do.

Actually I just used the bamboo as an example: multiple objects with a gradient to them and a way to bend them as one object without destroying the gradient.
Yes, Lazur used markers and I have tried that too but the outcome looks horrible :)

Something similar to this function:

Wow, that twist effect looks really cool.  I don't think Inkscape can do anything close to that.

There might be some way to create something like that with a gradient mesh tool.  But we're probably still years away from Inkscape having a gradient mesh tool in a stable version. 

As I think I posted in the IF version of this topic, bending a group of objects with gradients is a complex type of ability, that Inkscape doesn't quite have yet.  And since there are other programs which do have those abilities, I would guess that Inkscape developers will not be keen to provide it.....unless they could come up with some very programatically attractive way to do it.  I have the impression that developers get very excited about being able to do something in some new and different way.  But what that would be is far, far beyond my understanding.

Or maybe if it was a much requested feature, that's not available in any free or inexpensive program, maybe someone would be motivated to program it into Inkscape.

Btw, I'm going to move this topic into the Beyond the Basics board.  It will still appear in the index for this board, and will link to the thread, but it will say "moved".   :wink1:

Thank you, Brynn :)

Inkscape definitely has some features that I like so very much and I love to mess around with it :)
