SVG-edit needs to support Flip Horizontal and Flip Vertical tools in the
select panel.

Pushing this out to 2.4 as I don't think I'll be able to work on it

I'd assume we want to achieve this by offering a negative scale transform 
value, is
that correct? Or is there another (better way) you had in mind?

Well, here's the thing.  I've been doing my best to keep transforms out of the
elements unless they are needed.  So while transform="scale(-1,1)" sounds like 
the
right approach at first, you also have to realize that you'll need to translate,
scale, then translate back to achieve the effect you want.  This means you'd 
have
markup that looks like:

   <path transform="translate(200,200) scale(-1,1) translate(-200,-200)" d="...."/>

And that's looking a little too messy for my tastes :)

On that note, I think it would be more appropriate to calculate the new 
dimensions of
the element.  So if we have a path, that means calculating the new position of 
each
point when flipped on the x-axis (or whatever).

Yeah, I see what you mean. But would that work on elements like <text> and 
<image>?
If not, I think it would be better to use a method consistent among elements. 
And
would the translate really be necessary? You couldn't just reposition the 
element
using recalculateDimensions() ?.

Fyrd,,, I think you are right.  Means more complex xform handling tho

I'm pushing this out.  There is a chance that my work with transforms and 
groups make
this an achievable feature in the short term, but I'm not counting on it.

I created an extension based on the conversation above (interestingly enough, I 
didn't see this discussion until Alexis pointed it out on the other thread). 

There are two issues identified with this extension so far:
1. If a shape uses a gradient, it flips the gradient
as well. This may affect other shapes that share the same gradient (in my code 
I have made the clone tool to clone the gradients as well).
2. If the object is rotated, it doesn't flip correctly (as pointed out by 
Alexis here 
http://groups.google.com/group/svg-edit/browse_thread/thread/3a5d5222a522ec8a).

Attaching an updated version. Fixed the issue with the rotation. Also,
made some changes to preserve 'undo' history so undo & redo works as
expected.

This extension doesn't seem to work for me with the 2.6.  Should it?

GoogleCodeExporter commented 9 years ago 
I've made a few changes to get the flip to work with version 2.6. I hope this 
helps.

thanks for your replies but I am looking forward to work with a canvas where I 
can work simultaneously on 2 sides of paper (SVG).

thanks
