Autoscale, On / Off?

Postby ait » Thu Feb 05, 2015 3:47 am

Hello,
So I have a simple question but would appreciate the help...
I'm using the new inkscape that just came out.
I have an imported picture and I have been resizing, enlarging, skewing it, etc.
Then all of a sudden inkscape started forcing the scaling to be proportionate.
That is, every time I stretched the image in an un proportionate way, inkscape snapped the image back to its original form.

How did I turn this autoscale function on?
And how do I get it off?

[Oh...and I played with the small square buttons at the top, the first one that says "when scaling objects..." and they don't fix the problem. ]

thanks
a

Hi

To turn on/off proportional resize, click on the padlock Icon in the tool parameters. (Line along top of window).

Hi Ragistan,
After playing more with scale, I'm realizing that even when the lock is off inkscape sometimes automatically changes the image back to a predefined shape.

Any idea what else I can do to stop this from happening?

thanks

Just an idea: the spiro-path lpe can result in such behave.
Like on a closed path with three smooth nodes, with the spiro path lpe, it will become a circle right after scaling to an ellipse shape.
To avoid that, you can group the object and scale the group and not the object inside.

If Lazur's last comment doesn't solve the problem, maybe you could provide us an SVG file with an object that displays this behavior, so we can investigate.

May this help to clarify:

Try to scale each of the objects by their side bounding box handles.

Hi Lazur,

Thanks for the file...and I see that the blue one automatically snapped back to proportion when scaled, while the red one didn't.

However, I don't really understand why...sorry...

Although it seems the suggestion is somehow a spiro spline LPE was applied. But there are several steps to make that happen, how would I have happened to inadvertently applied that LPE?
Also, I made a copy of the red shape and then applied the spiro spline LPE and when I scaled the shape, it did NOT snap to proportion (or the original shape).

Clearly I'm missing something...any help is appreciated.
thanks

Hi.

Spiro path lpe can be added if you click on the pencil or pen tool's toolbar mode icon too, and as it remembers the latest settings, it can be confusing changing from one mode to another.


The lpe connects the core path's nodes with circular/clothoid (?) curves. Only the position of the nodes and node type matters (cusp or smooth).
So once you scale a spiro-path, its core path's nodes are transformed -their relative position to eachother-, and the path effect is applied after.
Resulting in a shape different then the original shape scaled.

If you put the spiro path inside a group, the lpe is applied on the unscaled shape inside the group, and the group will be scaled, resulting in a more predictable shape.


Hope it makes sence, cannot describe it much better.
