Draw vector drawable on canvas (image stretched)

I am creating pdf using PDF api provided in android,i want to draw image in pdf at specific x,y.

drawing done but because of small size the vactore drawable get streached and producing low quality output.

Here the code that i am using to draw drawable.

    Drawable starIcon = getContext().getDrawable(R.drawable.ic_star);
    VectorDrawableCompat moonIcon = VectorDrawableCompat.create(getContext().getResources(),R.drawable.ic_moon,getActivity().getTheme());

    PdfDocument.PageInfo pageInfo = new PdfDocument.PageInfo.Builder(595, 842, 2).create();
    PdfDocument.Page page = pdfDocument.startPage(pageInfo);
    Canvas canvas = page.getCanvas();

    float x = drawX + (perItemWidth * col);
    RectF rectF = new RectF();
    rectF.set(x + 2.5F - perItemWidth, drawY + 1, x + 1, drawY + perItemHeight - 1);

    float importantSpaceFromLeft = (rectF.width() * 10F) / 100F;
    float importantSpaceFromTop = ((rectF.height() * 2F) / 100F);

    Rect moonIconBounds = new Rect();
    moonIconBounds.left = (int) (rectF.left + ((rectF.height() * 10F) / 100F)) + 10;
    moonIconBounds.right = (int) (rectF.left + ((rectF.height() * 10F) / 100F)) + 20;
    moonIconBounds.bottom = (int) (rectF.bottom - importantSpaceFromTop) - 10 - 2;
    moonIconBounds.top = (int) (rectF.bottom - importantSpaceFromTop) - 20 - 2;

    //Setting bounds like 0,0,20,20
    moonIcon.setBounds(0,0,moonIconBounds.width(),moonIconBounds.height());
    canvas.save();
    //Translate canvas to draw at x,y
    canvas.translate(moonIconBounds.left,moonIconBounds.top);
    moonIcon.draw(canvas);
    canvas.restore();

    Rect starIconBounds = new Rect();
    starIconBounds.left = (int) (rectF.left + ((rectF.height() * 10F) / 100F)) + 10;
    starIconBounds.right = (int) (rectF.left + ((rectF.height() * 10F) / 100F)) + 20;
    starIconBounds.bottom = (int) (rectF.bottom - importantSpaceFromTop);
    starIconBounds.top = (int) (rectF.bottom - importantSpaceFromTop) - 10;

    //Setting bound from rect
    starIcon.setBounds(starIconBounds);
    starIcon.draw(canvas);

output

Both image producing same result drawbles are streatching, i don't know why both of vectors are converted from svg. How can i achive batter results.
