Re: Graphic file formats
I am not a pdf expert but this rather surprising given my experience with R plots. Rich, have you checked that the figures have not been converted to bitmaps with a default (and probably insufficient ) quality during this compression? You can check it by zooming in on the figures to see if they quickly pixellise and become ugly. -- Prof. Murat Yildizoglu Advisor to the Minister of Education, Youth and Sports of Cambodia Expertise France On leave from: UNIVERSITE DE BORDEAUX GREThA (UMR CNRS 5113) web: www.yildizoglu.fr > Le 9 déc. 2021 à 00:54, Rich Shepard a écrit : > > On Wed, 8 Dec 2021, Steve Litt wrote: > >> There are ways to shrink PDF size: >> Web search: linux shrink pdf size > > SteveT, > > First hit uses ghostscript; I never dove deep into gs and didn't know that > it can effectively compress a PDF file.

Re: Graphic file formatsx
This is not a problem of the text content. When you create a points plot in R, it puts the information about all the points in the exported PDF figure, even if many of them correspond to the same coordinates. It does not « flatten » the pdf figure. When you plot millions of points, that results in a lot of information and may necessitate considerable amount of memory from the computer for displaying on the screen or from the printer, to transfer on paper. When we export to a bitmap format like PNG, the information is « flattened » and all points that fall on the same pixels are coded just the value of these pixels. That makes the figure easier to handle. When you do a curve plot (like a density plot, for example) this problem does not exist. This is another strategy that I use when possible: can I show the same informed with a curve instead of with dots? If yes, I go for it. It is much more parsimonious. Using a bitmap format with correct proportions and sufficient density, the first solution gives very satisfactory results even if the figures are bitmaps. -- Prof. Murat Yildizoglu > Le 9 déc. 2021 à 00:37, Steve Litt a écrit : > > Rich Shepard said on Wed, 8 Dec 2021 07:51:56 -0800 (PST) > >> On Wed, 8 Dec 2021, Dr Eberhard Lisse wrote: > >>> For my big handbook (which takes 110 seconds to compile (70 on the >>> M1)) I have split this into child documents which compile >>> individually within 10 to 15 seconds. >> >> How about loading a PDF image that's 3,704,503 bytes in size while >> reading your big handbook? > > OK, 3,704,503 bytes got my attention.

Hi Steve, I’m not sure - but IMO the production of the index files should mention in the logs the fact of inconsistent page numbers. As long as this happens one has to redo the latex compilation process including the index creation. AFAIK LyX scans the logs and is doing exactly that. Please read the log files of your tools after the first run. Probably you’ll find some recommendation about this there. Sorry, if you are knowing this please ignore this message.
