  FREQUENTLY ASKED QUESTIONS

Why does the Mac OSX version not run on my mac?
If you are running OSX 10.5.x or earlier, k2pdfopt may not run on your system. See the first paragraph in my Mac install notes.

How do I increase the text size?
See the help page on increasing the magnification.

I just want k2pdfopt to remove the excess borders on my PDF file. Can it do that?
Yes. Use command-line options -col 1 -wrap- -vb-. This will turn off multiple column detection (-col 1) and text wrapping (-wrap-) and prevent k2pdfopt from trying to detect vertical breaks (-vb-) between regions (-vb- is a new option in v1.40). Additionally, you can use -ls to turn the document sideways and use landscape mode.

I don't understand how k2pdfopt is interpreting my PDF file.
Try using the -sm command-line option ("sm" from the interactive menu), which will write out a PDF file that shows the regions found by k2pdfopt.

Some of the text is truncated. Can I fix that?
Yes. By default, k2pdfopt ignores a 0.25-inch border around your document. Turn this off by using command-line option -m 0. See Ignoring Borders/Headers/Footers.

Some of the text is much larger than the rest. How can I avoid that?
If your document does not have multiple columns, try turning off multiple column detection with command-line option -col 1 (interactive menu option "co"). See the page on column detection and also the page on showing markings so that you can see how k2pdfopt is converting your document.

How can I get rid of the document headers, footers, and/or page numbers?
You can tell k2pdfopt to ignore an arbitrarily sized border around your document. See Ignoring Borders/Headers/Footers.

Sometimes I get multiple rows of text at smaller magnification than the rest of the document. Why?
This generally happens when there is not a clear gap between rows of text and k2pdfopt thus views the region as a graphical block (figure) rather than as rows of text. See this mobileread.com thread for tips on how to adjust your k2pdfopt settings (posts #45 and #46).

Is there any way to search the text in the converted PDF file?
Not at this time. The output from k2pdfopt is rasterized and therefore not searchable. A future release might have an option for a different type of output that would use cropping instructions rather than rasterizing to generate the converted file (similar to what is done in Cut2Col and SoPDF, which both leave the text in searchable form if it started that way in the original file).

My PDF file has a lot of pages. Can I convert only certain pages?
Yes. See the Windows Getting Started page and scroll down to "2. Enter Page Range" (or use the -p command-line option).
