Description Vassilis Chryssos 2013-11-28 11:48:56 UTC
When aligning two objects the system seems to arbitrarily choose which object is used as an "anchor" to align the other one. At times it seems as though all objects move to meet the common alignment line.

This poses a usability issue, when you want to align objects relative to a fixed object. The user should be offered the choice to select which object will be used as a "base object" for the others to align to.

How do we go about aligning two objects in this manner? When in doubt please always include steps - we have thousands of bugs that we need to process and time saving from good steps is always appreciated. A test document might be useful here also.

Setting to NEEDINFO - once you provide clear steps and perhaps a test document mark the bug as UNCONFIRMED. Thanks!

three objects to showcase the alignment problem

Three objects: blue, green, red. 
User wants to align them to the left edge, at the vertical position of the green rectangle.
If the user selects all and align them, they will move to the leftmost edge, aligning by the left side of the red rectangle. There is no apparent way to choose which rectangle will be used as basis for the alignment.

You can do this way:
right click green object - Position and size - Protect - Position
select three objects - button click align left
Is it sufficient?

I guess this does the trick! It should be easier for the end-user, though. When designing a layout one needs to have tools to allow for swiftness and ease of use. This is the way it works in Inkscape, GIMP and other programs as well.

setting as NEW enhancement.
For  example inkscape allow more choices to align, see http://tavmjong.free.fr/INKSCAPE/MANUAL/html/Align.html

Valid also for other modules - Writer, Impress, Calc.

Please, take the suggestion in bug 84463 as a possibility to solve the issue.
Namely, always align to the first object that has been selected.
In other words if one has 3 objects "red" "green" and "blue" and wants to assure that they are aligned to the "green" one, let him select the green object, then shift-click the "red" one to select that too, and finally shift-click the "blue" object to add that too to the selection. Then align. Being the "green" object the first one added to the selection list, it should get used as the fixed object. This is easy to explain and does not require additional elements to clutter the interface.

"The alignment of objects is with respect to an anchor. The anchor can be an object or be defined by the selection, drawing, or page; the choice of what is used is set in the pull-down menu Relative to. The object may be specified to be the first or last object selected. If multiple objects are selected at the same time, this is equivalent to the top or bottom object in z-order. Alternatively, the object can be specified to be the biggest or smallest item, where size is determined by the size of the bounding box, the width for vertical alignment and the height for horizontal alignment. The bounding box sides are used as the reference points for alignment except for text, where the baseline is used."


Way too complex. I'd always use the object as reference that was selected first (as also suggested in comment #8). It has to be indicated somehow, e.g selection handles remain visible. But that's a question of tdf#74364.

This one is about the exact placement of a single object taken from the gallery.

I fully support that idea.
Taking freedom to adjust summary ;)

Setting Assignee back to default. Please assign it back to yourself if you're still working on this issue

+1 for this feature request because the existing solution of locking the position of the reference shape is not handy at all!
