Rounded corners do not scale when 2 rectangles with R=4 grouped

[marcel]

I´m working with Inkscape 0.45.1+0.46pre1+devel, built Feb 1 2008 (WIN XP)

For expample I scale a group consisting of a rectangle object and a path with "Object-->Transform" by 50%.

Before scaling:
Dimensions of the rectangle objects are: W=100mm H=100mm Rx=4mm Ry=4mm

After scaling:
Dimensions of the rectangle objects are still the same! even so it has been scaled effectively!: W=100mm H=100mm Rx=4mm Ry=4mm

When a single rectangle is scaled rounded corners are scaled properly but not when it is part of a group.

Steps to reproduce:
* Create two rectangles (set rounded corners to Rx = 4 and Ry=4)
* Group them together
* Select Transformation (Shift+Ctrl+M) and Scale by 50%
* The rectangles are scaled properly but rounded corners are still Rx and Ry=4 for each
* If "Affect: rounded corners" is turned off the corners of the scaled (down) rectangles now have Rx=8
* If different radius is chosen (say 10) the transformation works as expected
* If more than two rectangles are added to the group the transformation works correctly as well

Tested with rev. 17566 (29 Feb 08)

Yes the rectangles scale properly as you say.

However the dimensions, I mean the numbers, shown in the rectangle tool are wrong (remain unchanged) after scaling within a group.

[Marcin Floryan (mfloryan)]

Well, I am not sure. The dimensions of the rectangles do not change because the group is rescaled and not the rectangles. Whether this should be reflected in the UI - probably yes. I would be more concerned about the inconsistency of this behaviour. And the fact that in one case the rounded corners radius is scaled up, not down.

Some SVG snippets:

before:

<g
       id="g2395">
      <rect
         ry="3.3333333" rx="3.0107527" y="335.21918" x="185.714" height="200" width="200" id="rect2383" style="fill:#3a7c0e" />
      <rect
         ry="4.2682924" rx="4.2168674" y="436.64792" x="280" height="250" width="250" id="rect2385" style="fill:#f4cece" />
    </g>

after:

<g
       id="g2395"
       transform="matrix(0.5,0,0,0.5,178.9285,255.46677)">
      <rect
         ry="3.3333333" rx="3.0107527" y="335.21918" x="185.714" height="200" width="200" id="rect2383" style="fill:#3a7c0e" />
      <rect
         ry="4.2682924" rx="4.2168674" y="436.64792" x="280" height="250" width="250" id="rect2385" style="fill:#f4cece" />
