------------------------------------------------------------------
I had a look at other operators and notice that they do a transformation, but
the dash pattern isn't transformed in
org.apache.pdfbox.util.operator.pagedrawer.SetLineDashPattern. Inserting this
code
{code}
float[] dashArray = null;
if (!lineDashPattern.isDashPatternEmpty())
{
dashArray = lineDashPattern.getCOSDashPattern().toFloatArray();
Matrix ctm =
context.getGraphicsState().getCurrentTransformationMatrix();
if (ctm != null && ctm.getXScale() > 0)
{
for (int i = 0; i < dashArray.length; ++i)
{
dashArray[i] *= ctm.getXScale();
}
}
}
{code}
and using that dashArray result instead of
lineDashPattern.getCOSDashPattern().toFloatArray() later down produces the
attached image (which includes my change from PDFBOX-615).
