Problem when rotating to horizontal

[rmcdouga]

I'm seeing an issue when I run the following test:

    @Test
    void testSvgProblem() throws Exception {
        SVGGraphics2D g2 = new SVGGraphics2D(4986, 3216);

        int marker_size = 65;
        int local_diameter = 600;
        int radius = local_diameter/2;
        double arc_size = Math.PI / 12;

        g2.translate(1000, 500);

        g2.setColor(Color.BLUE);
        g2.setStroke(new BasicStroke(2));
        g2.drawOval(-radius, -radius, local_diameter, local_diameter);

        // draw sector lines
        g2.drawLine(0, -radius - marker_size / 2, 0, -radius + marker_size / 2);

        g2.rotate(arc_size*2);  // rotate past the orbit arc

        // draw sector lines
        int halfMarkerSize = marker_size / 2;
        g2.drawLine(0, -radius - halfMarkerSize, 0, -radius + halfMarkerSize);

        for (int i = 0; i < 6; i++) {
            g2.rotate(arc_size);
            g2.drawLine(0, -radius - halfMarkerSize, 0, -radius + halfMarkerSize);
            g2.drawString(Integer.toString(i), 0, -radius);
        }

        String result = g2.getSVGDocument();
        Files.writeString(TestConstants.ACTUAL_RESULTS_DIR.resolve("TestSvgProblem.svg"), result);
    }

It creates a circle and then creates a series of lines that are perpendicular to the circle. When the line is horizontal (as in line 3), the transformation matrix looks like it is incorrect.

Does this happen with version 4.2? I think it is probably related to https://github.com/jfree/jfreesvg/issues/35 which is fixed for the next release. I have a couple more things to tidy up then version 5.0 will be released. For now I would recommend to drop back to version 4.1.

You're correct. This happens in 4.2 but does not in 4.1.

I have backed off to 4.1 for now. Thanks for the help!
