I think the main issue is that -rt 90 isn't really intended for what you're using it for. It is intended to be used for source files which are incorrectly in landscape mode (e.g. if when you view them on a standard PC reader they come up sideways). That is, it rotates the source file before doing any other processing. So if you have an 8.5 x 11-inch source file, it will be rotated and treated as if it is now an 11 x 8.5-inch source file by all the other processing. That means your grid argument now has to be 2x1x5 instead of 1x2x5. Similarly, your -cbox arguments need to change. Fortunately, there's a much simpler option, which is to use -ls rather than -rt 90. This acts as if you want to turn your reader on its side to read the document, so it fits the source file to the sideways (or landscape) dimensions of your e-reader screen and turns the output page on its side. That's what you want to be using instead of -rt 90. (The -ls option is turned on by default when you use -mode fw). |

Also check "rotate to landscape" box if uncheked, and if correct -w and -h width/hight size for your reader is showed there in the field. First picture: -grid command used in copy conversion mode; the whole width of the page selected for rotation to landscape (both red frames stretched maximally) Second picture: -grid command used in default or fitpage/fitwidth/trim "conversion mode"; just text proper will be selected when possible (second red frame), so no boundaries will be visible after rotation to landscape. To be able to see (in preview window or in pdf file) how k2pdfopt interprets the page (those red frames) you should check "generate marked-up source" box.

You guys are worth your weight in gold.
Will: Replacing -rt 90 with -ls did the trick. After much trial & error, I guess the default fit width is the best bet. Using this, sometimes the diagrams get cut off, but its the best option for text (that's what books are for, right?). I tried to play around with the grid option, it is good for the diagrams, but not so for the continuity of text. With/without specifying the output size for my M96, & due in part to the inefficiently/over-zealously cropped margins in briss, I think it struggles to fill the pages with the available content & leaves empty space at the bottom of the page (if viewed in output landscape mode). Just not worth the trouble. I'll just leave the thinking to k2pdfopt. Mark: M96 software is still a work in progress. Its default reader allows full screen landscape mode but has a lot of lags (5-10 seconds or more) while switching pages even in the latest software version, & sometimes garbles/eats up page contents altogether. Other apps like ezPDF are better, but then they don't turn pages with buttons/d-pad in landscape & need to move the page with stylus, or need elaborate workarounds like a precise zoom, assigning volume keys for page flip & then work perfectly. Phew! All-in-all I guess conversion to landscape using k2pdf & then asking M96's native viewer to treat it as normal portrait is the most efficient compromise. Jp |

We'll get a lot bigger pdf e.g. 50 MB instead of original 5 MB, but a lot quicker one to render and flip through on ereader. e.g. pdfs from archive.org https://archive.org/details/TheAdven...mSawyer_201303 Last edited by markom; 10-02-2014 at 05:39 PM. |

If you do find it and it turns out to be as problematic for opening as Tom Sawyer, you can also download djvu file and open it in free DjView 4.9 (or earlier) djvu reader and save it (export it quickly) as pdf, or open it in k2pdfopt and save it using copy mode.
Result is similar i.e. 10-20 x bigger pdf bitmap. These are two (free and quick) ways to optimize(turning into bitmap) slow-to-open-or-browse pdf's for reading in ereaders and tablets. We can also easily read those archive.org djvu files directly on Kindles (KPV reader, KOReader) using all zooming options as available for pdfs, or on tablets like iPad using good free djvu readers. And last but not the least, we can use k2pdfopt to optimize those djvu files as we would pdfs. To be able to see and add djvu files to k2pdfopt after pressing Add-File button, we should select all-files or djvu instead of pdf, in drop-down list on the bottom.

Hello Willus,
I have a minor problem. Please consider input and output files I have attached. The chapter number at the top of the page has been removed. Any suggestions? Friendly regards, Angelos |

Dear Willus,
I bought the Kindle Paperwhite because I wanted to save my eyes while reading large amounts of electronic text. I'm an over-50 grad student and did not know that e-readers aren't the best choice for reading pdfs, so I was thrilled to read about converting pdfs with k2pdfopt. Unfortunately, every time I try to download the program, I get an error message, "Download ended." Can you please help? Janet Bailey |
