Summary0011647: Alignment functions don't work uniformally with lines of width greater than hairline
DescriptionWhen you have a line that has a width greater than hairline the alignment functions don't work correctly all the time. See steps and forum post mentioned below.

Merged from 0014020 "Lines that are widened don't snap to margins correctly"
Observations when viewing  line-doesnt-snap-correct.gif  line-doesnt-snap-correct2.gif 
a) the narrow end of the line if attempted to snap perpendicularly will show the preview incorrectly (juts out farther then the margin/guide) but snaps correctly when mouse is disengaged

b) the sides of the line if attempted to snap parallel to a margin/guide will not snap line correctly to the edge but instead to the midline of the line itself

Steps to Reproduce:
1) Draw a line (Press L and hold command key to keep orientation to 0 degrees)
2) Go to PP > Line > Line Width and set to 20pt
3) Click on line and drag it to one of the margins or a guide 
Result: Dragging perpendicular or parallel will show incongruent behavior mentioned above in a) and b)
Steps To ReproduceOne example:
1. Create horizontal line (0 degrees).
2. Make line wider (e.g. 30pt).
3. Create frame.
4. Select line and frame together.
5. Use "Centre on horizontal axis" alignment tool.

The frame is aligned to the outside of the line rather than the actual line itself.

Maybe this has been fixed in 1.5 ?

Unfortunately, since upgrading to Mavericks, I can't recompile 1.5.0svn to check. (cmake presents an error that I can't resolve with my minimal technical knowledge, but that's irrelevant here.) Maybe someone else can check this?

I confirm the bug happens on 1.5.
As stated in the forum, it only happens when line angle is 0°.

scribusdoc.cpp (12779) (yes : 12779) reads as follow :
double diff=newY-AObjects[i].y1-(AObjects[i].height)/2;

The XYZ pane of the PP displays the height of a line object to be allways 0.353mm (but greyed), even if the line has a strong thickness, like 10mm.

All the same, there is no "center on vertical axis" placement issue when angle is not 0°.
So the XYZ "witdh" entry of the PP does not display the value of the "width" property used in the formula ? Hmm

Reproduced with 1.4.4 (19167) and 1.5.0 (19179)

The issue is also very visible when bottoms/tops are aligned.

Just noticed now, why is the priority set to Low? It should be as least Normal.

I think I set it to "Low" priority when I created the issue originally. I don't mind if it's bumped up the list of priorities.

I tried to fix this a few weeks ago.. its requires a lot of work. Its not a quick fix. Likely 12-24h of solid work. Moving to 1.5.1 roadmap

Issue has been replicated in 1.4.5. (Changed product version number in ticket as appropriate.)

A similar problem occurs when you have thick lines and are resizing a shape using snap to grid/guides.

Basically, once you change the width of the line of a shape, the snapping functions work to the visible part of the shape rather than the line itself. See attached GIF (grid snap) to see it in action.

A similar issue can be observed in 0013887 "Arrows at the end of a line should point to the end of the line, not further away"

Also encountered 0013706 when reproducing this ticket
