A few days ago I posted a question regarding how one can set the line width used by the Laserwriter. The tech support people at Apple provided an answer, which I am passing on in case anyone is interested. All you need to do is make a call to PicComment with kind=182 (see IM), dataSize=4 and a dataHandle which leads to a Quickdraw point. The vertical component of the point is the numerator and the horizontal component is the denominator of a scaling factor that the current pen size is multiplied by to obtain a new pen size. For example, if the point is (v=2,h=7) then the pen width and height are multiplied by 2/7 to obtain the new pen size. Apparently there was an error in Tech Note #91, which claimed that the new pen size is given directly by the components of the point. This seems to work, although I found that I needed to preceede the PicComment with at least one call to DrawString or LineTo (e.g. write a space character with DrawString), otherwise nothing printed.
