Hi Zolnai,

I'm sorry for the late reply.

Please refer to the fdo#37129.

That's right.
When we call "ApplyLineDashing without scale", the snipet size is completely different in Calc and Writer.
"ApplyLineDashing with scale" is intended to prevent this.
In LibreOffice 3.3, the size of the snipet was roughly the same in the appearance on the screen in both programs.

Best regards,
Tomofumi Yagi.
