Careful comparison (e.g., by aligning the pages on top of each other and blinking between the two every second or so by alternatively iconifying and deiconifying the one on top) of pages 3 and 4 of the 19th standard example shows there are some subtle visual differences beyond the obvious "Baltimore" label on the 4th page. In particular, the dashed lines of latitude are rendered slightly differently in the lower right quadrant of the plot. (I have verified this issue with the xcairo, pscairo, qtwidget, epsqt, and xwin devices so I don't think it is a driver issue.)
With regard to the lines of latitude, the only difference between the two pages is plstransform is being used for page 4 but not for page 3. If you use diff or ndiff between the two pages rendered as PostScript (using the -fam option so you can generate a separate file per page), there are lots of relatively big differences (which presumably I spotted visually) and also many intermediate and small differences as well. If plstransform is doing its job properly, shouldn't the two pages be absolutely identical except for the Baltimore label? Alan __________________________ Alan W.
