Yet another PDF to LRF converter - Page 16

I guess you have ghostscript installed right? Any idea about what the error message says?

ereszet · 10-04-2007, 05:21 PM

Cacapee, it looks that at some stage you have changed the default setting for overlap% to 0.0 (Windows version). Was there a reason for that? The lines at the end of some pages in a document I processed with default settings were broken horizontally. The overlap setting of 0.05% worked all right by repeating the last line as the first line in the next page. Can you make it a default? (I have not conducted a thorough study with different documents, so 0.05% may not be the best for all cases, but my document page was quite typical A4 size from Word converted to pdf).

I think the best way to deal with the question of defaults would simply be to allow you to save your own defaults to a file (or the registry, if you want it to persist across versions).

I would much prefer that, as I usually go for the portrait mode and I have to remember to change it each time. I know I would prefer no overlap or almost no overlap. so even then, somebody like me would have to remember to change it each time.

This is a tremendous program that just keeps getting better...

Would it be possible to differentiate between text and graphics and if graphics would either be split among pages or of a larger resolution then the screen to make the graphic start on a new page and/or resize it for a single screen? That way things like equations or diagrams won't be split and still be useful.

As far as I understand pdflrf, all is graphics. The pdf/djvu input is converted to image files and the ouput is an image contained in lrf (or a set of png images).

The output is graphic pages yes, but the input may not be just graphics.

You can get a similar effect by checking runpages but unchecking split pages.

ashkulz · 10-06-2007, 12:54 AM

cacapee, now that pdflrf is stable do you have any plans of opening the source for it? I'm mainly interested in getting it to work with other devices/formats, as I want to avoid duplication of effort in enhancing pdfread to support the features pdflrf has.

cacapee · 10-06-2007, 01:02 AM

Almost there. I'm presently porting over to Qt.

Quicktime? ACK!

They really do need a better name for it.

So now, that you are almost there with version 1, you may consider one more idea for the next version.

I am suggesting an lrf file as input and a png file as output, which means that it would be possible to print lrf files via png.

I am not suggesting printing the books, but with all kind of documents that I store in Sony (e.g. business cards), it would be possible to print them when a need arises (via png and SD card).

And of course a user settings file to make my own defaults.

Creating LRF files and displaying them are two different kettle of fish together. It'd make more sense to use the LRF renderer in libprs500 to render PNGs. One more feature request for Kovid :-)

OK, I give up. I appreciate the great conversion tool, but can't figure out the various settings. (The brief descriptions when mousing over the checkboxes isn't enough, alas.)

Here's what I want to do. Can anyone detail which settings I need in pdflrfwin?

I want to convert a pdf (with some images, 4-level gray is fine), rotated 90 degrees (landscape mode), with each page split in HALF, and size of the top or bottom page half adjusted to the sideways screen. (left-right centering would be nice too, but not critical.)

I keep getting lines of text split, or a third screen for each page that's blnk except for a page number, etc.

Also, what is the real difference between the filter options?

TiA....
