Wow, 4000 pages. I never envisioned k2pdfopt would be used on such a large PDF. Are you converting an encyclopedia? I'm not sure what you mean by "cmd". Are you using the Windows GUI? Does the GUI start flashing? Does the conversion finish? It's conceivable that you're running out of memory since this only happens on the 32-bit version--you might check the task manager while k2pdfopt is running to see if the memory usage is approaching 2 GB of RAM. If you want to post a link to the 4000-page file (or PM it to me), I can investigate, but I would recommend that you convert such a large file in pieces--maybe 1000 pages at a time (e.g. put 1-1000 in the "Pages to convert" box, then 1001-2000, etc.).

With your great software imade conversion of big pdf without problem. With cmd i want to say command prompt. I never hadproblem like this with your software untill i change command prompt parameters, now intead of black i have blu as background. I also have change dimension of command prompt, but now i have reported to default. untill this changes all was ok. Yes, i sendo you a dropbox link of the pdf in pm. Yes, i use windows gui. Command prompt flashes, blinks whne conversion goes to about 4000 pages. Now with command prompt with defalut parameters cmd blinks. I'm going to restart the conversion and i'll say you the message of the gui. with 64 bit version conversion is ok. i've 8 gb of ram.
thanks for what you do.

That is an interesting version of Windows you've got there. Custom OSX-type skin, looks like. Does the blue command-line window appear to get launched by k2pdfopt late into the conversion? Or did you already launch it yourself (separately from k2pdfopt) and it just starts to suddenly flash at some point during the conversion? Also, can you post a screenshot of your GUI settings that you use for the conversion so that I can exactly mimic your settings? Did you try checking the task manager to see if you are running out of memory?

Yes I use a osx theme. windows 8.1. when i launch k2opt i see rapidly a black command prompt (i use a blu command prompt). The amount of the ram is near 1,5 gb when k2opt crashes.

It is correct that the command prompt flashes onto the screen momentarily when the GUI is launched. That is normal and due to the dual GUI/command-line nature of the program (once k2pdfopt determines that the GUI mode is desired, the command-line box is terminated, so it should go away immediately after launching).

Please post a screen shot of your GUI settings for the conversion.

@sage79 -- Thank you. So I'm trying to understand exactly what is happening to you. Is it (1) that you are working in another command-line window while k2pdfopt is converting, and when k2pdfopt gets almost done with your 4000 page conversion that the command-line you are working in starts to behave abnormally (flashing), i.e. k2pdfopt is affecting the behavior of an already-open command-line window? Or is it (2) that when k2pdfopt gets far enough along in the conversion, a new command-line window suddenly opens (without you trying to open it) and starts flashing abnormally?

@sage79 -- Okay, I tried your conversion in the 32-bit Windows version, and it ran out of memory after converting about 2500 source pages (resulting in a 1 GB(!) PDF output file, though malformed since it quit unexpectedly). I will investigate to make sure it's not a memory leak of some sort. Thank you for the example. It is a good extreme test.

I appreciate the sentiment. I usually tell people that they should donate the money to some other open source effort or to charity. I am fortunate enough that I don't need it. You have already helped me by giving me a good test case.

I've patched three memory leaks for the next release, one of them fairly significant, which will fix this problem.

By "blank space" are you referring to the region surrounded by the red rectangle (see attachment)? Is the text from the green region displayed correctly on the next output page? Are the light blue regions showing because you have done a "select all" command? If the answer to all these questions is yes, then k2pdfopt is behaving as I expect. If it is causing problems for you, you may wish to turn off native mode (uncheck it). If you do that, you can also remove the -bp m to reduce the amount of blank space on each page. If (after turning off native mode) the bitmapped output needs to be higher fidelity, try increasing the "Document Resolution Factor."

Just wanted to throw in some greetings. Really nice to see that you still find ways to enhance k2pdfopt Willus.
All the best
