Well that volunteer has stepped forward for quite a few of the issues. Thanks, Hazen. I have also made some progress myself. However, there are still some issues left. I didn't check all the examples this time, but to start I did look at examples 1 and 2, and the vertical spacing still looks good after our recent changes (Revision 8853). > (*) Example 3: the text does not rotate accurately around this polar plot. > For example, the center of the text rotation seems offset from the center of > the plot.

(*) The example 3 issue and example 28 page 1 issues are fixed thanks to Hazen's changes. However, a remaining issue (probably completed unrelated) seen for example 28 pages 2 and 3 is that subscripts are being interpreted as superscripts (!). > > (AWI) Example 6: some of the horizontal rules are missing.

The empty pages in Example 20 were caused by extra pladv(0) calls. I got rid of those extra pladv(0) calls to get rid of the empty pages associated with that example. However, generating empty pages should be a valid under PLplot so I started working on an equivalent simple example consisting of repeat pladv(0) calls. For that simple test, I solved the issue by my recent plGetFam change that restores the initial value (AT_BOP) of pls->page_status when plGetFam is called from the driver's plP_bop-* routine after the plP_init call. plP_init changes the page_status to AT_EOP which screws up the page logic for empty pages for the familied case without the restoration of the initial value of pls->page_status. > > (AWI) Example 21: first four figures (out of 6 on the second page) display > and then get blanked.

Fixed by my recent plGetFam change, see above. The issue here was not empty pages, but instead pages consisting entirely of text. Such pages currently do not change page_status (which is why my plGetFam empty page fix also solved this issue). However, just on general principles, I think such pages should change page_status so that issue is being discussed in the separate README.pages list thread. In sum, we have made some good svg device-driver progress as of revision 8853, but I still have two issues I still need to look at (ex. 6 missing lines, and ex. 21, page 2 where 4 of the 6 subplots disappear), and there are three others (ex. 28 subscript/superscript, ex. 10 text rotation, and ex. 15 cross-hatching) that are probably too difficult for me so I hope someone else will take them up.
