When using the AWT renderer of FOP 0.94 I find that at the default zoom level the horizontal lines at the top and bottom of some borders are not visible. If I zoom in then the borders appear correctly. They also appear correctly when printing (or saving as PDF).
Adding the following line to getPageImage in Java2DRenderer resolves the problem: graphics.setRenderingHint(RenderingHints.KEY_STROKE_CONTROL, RenderingHints.VALUE_STROKE_PURE); Is this a known issue?
