I try to construct a regularly spaced, diagonally striped pattern. Beginning with on diagonal line in the upper left corner, "tile clone" produces a mismatch between the columns and the rows. When I construct the pattern by hand and use it on an object I get similar mismatches between the pattern-tiles.
An example to visualize the problem: I fetched this pattern from openclipart.org:
http://openclipart.org/clipart//special/patterns/pattern-pinstripes-diagonal...
An object filled with this pattern looks fine.
Now, convert with "pattern to objects" (which I did to change the colour) and convert back with "objects to pattern".
An object filled with the resulting pattern shows the mismatch.
Then I changed the colour in the source, but there is a principal question: Is something wrong and if so, what? And why doesn't this affect the "pattern-pinstripes-diagonal" pattern? Maybe I just missed an important point in constructing patterns in inkscape?
Cheers,
Henning
