Currently, PrizmDoc will display lines as they are defined in the PDF file while other viewers like Acrobat Reader adjust the displayed line width to make sure it is never smaller than 1 pixel visually at any zoom level. Having the viewer automatically change the line width for lines thinner than 1 pixel to 1 pixel would allow users to not have to worry about using the Image Tools to manually increase line width and allow for a more fluid user experience.
