Whenever I alter a figure with Paint.Net, insert it into a Word document, and convert the doc to pdf with NovaPDF, the figure comes out trashy. First, the pdf conversion inverts the colors. I can fix that by inserting an inverted color figure into the document. However, rows get out of line,especially with added text, as well as other numerous artifacts. The figures are being created in Matlab. The figures that I insert without ever having been altered in Paint.Net convert perfectly. What can I do to prevent the conversion errors?
