Bug Description

Binary package hint: inkscape

The tiled clones tool does not create any offset between parallel clones of vertical or horizontal lines, no matter what is specified on the "Shift" tab of the tiled clones dialog

To reproduce:

1. Draw a vertical line (hold CTRL while drawing to ensure it is perfectly vertical)
2. Edit->Clone->Create Tiled Clones...
3. On the "Symmetry" tab, select P1: Simple translation
4. Enter Rows, Columns = 1, 5
5. Click "Create"
>> five clones of the line are created, all stacked on top of each other.
6. Undo
7. On the "Shift" tab, select 200% per column for Shift X.
8. Click "Create"
>> five clones of the line are created, all stacked on top of each other.

In other words, the width of the stroke is ignored when calculating the offset between clones.

Workaround: temporarily switch to 'Geometric bounding box' mode [1], select the line and create the tiled clones - the stroke width is now included in the width or height of the base tile and takes effect in the calculation of the horizontal or vertical offset (in %) of the 'Shift' parameters. I don't know if this contradictory use of the bounding box mode is intended or just an error when parsing the current bbox mode used for the calculation of the base tile dimensions.
(tested with Inkscape 0.47, 0.48 and 0.48+devel r9828)

Oooh, it took hours for me to finally nail and identify this bug... I would offer near-eternal gratitude and an extra donation towards the LGM budget if someone would fix this.

This bug also occurs for paths with arrows. A rather fast workaround is to bend the straight line before the cloning, and then suppress any Béziers handles (all clones then becoming straight together with the original).
