Line Width: Setting the Line Width in Pixels

Line width: Setting the line width in pixels

By default all graphics lines are drawn 1 pixel wide, but on hardware that supports it you can increase this to <N> pixels.

A common reason for doing this is to improve the appearance of images being transferred to avi or mp4. Lines taken from a high resolution computer graphics display often become patchy in movie files, so increasing the line thickness greatly improves their visibility.

You will notice that drawing takes much longer with thick lines: this is because the graphics device has to render more pixels.
