But what do you do when you see that both plsc->xdpi and plsc->ydpi are set to PLPLOT_DEFAULT_API? (See my second previous post in this thread concerning PLPLOT_DEFAULT_API.) Did the user set that because they wanted that exact value, or is that the default value which you can then override by following the Microsoft prescription? Maybe for the default we should set plsc->xdpi = -PLPLOT_DEFAULT_API; plsc->ydpi = -PLPLOT_DEFAULT_API; as a well-known signal that we want to use default DPI? Most drivers would then simply use PLPLOT_DEFAULT_API if plsc->[xy]dpi was set to the negative of that, but some might use a different default value instead (such as the Microsoft prescription) if either plsc->xdpi or plsc->ydpi was -PLPLOT_DEFAULT_API? Just thinking aloud here to stir up more discussion.... Alan __________________________ Alan W.
