Only on exact vertical and horizontal lines - if the mid point of the pixel fall of the center point of a screen pixel. On curved or diagonal lines there is no contrast loss, because of anti-aliasing already. If the developers knows he is drawing exact vertical or horizontal lines (eg: the background grid in a graph), the AggPas API has an extra boolean parameter that will grid-fit the line (loosing accuracy, but keeps line sharpness). I personally prefer accuracy, so don't mind that - the same reason I don't enable font hinting (forcing text to fit a grid) in my desktop environment. I prefer the true shapes of character glyphs - like the font designer intended. > Another problem with scaling is the thickness of lines. Example: you If you apply scaling, obviously your software needs to apply it to everything. Line thickness, font sizes, image sizes, widget sizes, form sizes etc. I have no idea if the new high DPI feature in Lazarus 1.7 goes into all that detail. It would be interesting to know.
