Description Bill Lewis 2004-09-23 16:46:08 UTC 
Version:           1.3.0 (using KDE KDE 3.3.0)
Compiler:          gcc (GCC) 3.3.4 20040623 (Gentoo Linux 3.3.4-r1, ssp-3.3.2-2, pie-8.7.6) 
OS:                Linux

If the diagram (Use Case, Activity, State, Collaboration, Sequence, Class) has items "too close" to the top and/or the left edge, then when exporting the diagram there are thick black lines on the top and left edge of the image.

This creates a small dilema as we have many diagrams fairly tight to these two (2) borders too limit printing to one page, however, once exported for inclusion in a document, then the black lines are visible. Thus the diagram needs to be resituated in the middle for export.

Reproducible always, on several workstations with the same versions of KDE and Umbrello.
Comment 1 Modestas Vainius 2004-10-14 00:23:13 UTC 
Consider this extract from umlview.cpp:873 (UMLView::getDiagramRect()):
------------------------------------
       }

        // Margin:
        startx -= 24;
        starty -= 20;
        endx += 24;
        endy += 20;

        return QRect(startx, starty,  endx - startx, endy - starty);
}
-------------------------------------------
in case of "startx" < 24 and/or "starty" < 20, the values of these variables will turn negative after decrement. I suppose, this should not happen. As this rect object is later used to define the area in a diagram to be converted into an image, unexpected results are produced. Furthermore, as UMLView::getDiagramRect() is extensively used in the code, this bug may be a cause of other problems.

I'm using Umbrello 1.3.1 and KDE 3.3.0
