Subject Re: freetext, drawing, polygon annotation

Hi tilman. this is my code.

COSDictionary ddict = new COSDictionary();
ddict.setName(COSName.SUBTYPE, PDAnnotationMarkup.SUB_TYPE_INK);

COSArray newInklist = new COSArray();
for (DrawingPosition dp : getDrawingPositions()) {
    float[] drawPointXY = new float[2];
    drawPointXY[0] = dp.getX();
    drawPointXY[1] = dp.getY();

    COSArray newArray = new COSArray();
ddict.setItem(COSName.INKLIST, newInklist);

PDAnnotationMarkup inkAnnot = new PDAnnotationMarkup(ddict);

PDBorderStyleDictionary drawBorderDict = new PDBorderStyleDictionary();

The array of x,y points looks like this

COSArray{[COSArray{[COSFloat{462.9}, COSFloat{549.6}]},
COSArray{[COSFloat{462.9}, COSFloat{550.8}]},
COSArray{[COSFloat{462.30002}, COSFloat{552.6}]},

COSArray{[COSFloat{282.3}, COSFloat{558.0}]}, COSArray{[COSFloat{278.1},

COSArray{[COSFloat{246.3}, COSFloat{510.0}]},

COSArray{[COSFloat{214.5}, COSFloat{500.4}]}, COSArray{[COSFloat{208.5},
COSFloat{500.4}]}, COSArray{[COSFloat{200.09999}, COSFloat{500.4}]},
COSArray{[COSFloat{194.7}, COSFloat{501.0}]}, COSArray{[COSFloat{188.7},
COSFloat{501.6}]}, COSArray{[COSFloat{184.5}, COSFloat{503.4}]},
COSArray{[COSFloat{179.7}, COSFloat{504.6}]}, COSArray{[COSFloat{176.7},

COSArray{[COSFloat{171.9}, COSFloat{508.8}]}, COSArray{[COSFloat{170.1},
COSFloat{510.0}]}, COSArray{[COSFloat{168.9}, COSFloat{511.8}]},
COSArray{[COSFloat{168.9}, COSFloat{512.4}]}, COSArray{[COSFloat{168.9},

Attached is the result
