IMP conversion - Page 2

JSWolf · 04-16-2007, 05:03 AM

I did manage to load an IMP file into Wordpad and strip out the junk and also figure out what some of the symbols meant for a search & replace. And I have removed the extra space between the paragraphs and I think it came out pretty good when I was done. Just have to load the LRF now onto the reader.

Yes. That would be it. Most of my imp files were made with ebook publisher. I have just checked one that I purchased from ebookwise and I see what you mean!
Sorry, in that case I'm stumped.........

Then, as far as I know, a couple of years ago GemStar transfered (or sold) the format rights and the rest of non-sold devices to eBook Technologies.

More or less detailed imp description can be found here

P.S. At the beginning of imp-files there is a sgnature BOOKDOUG.

I had found that page previously, but it didn't have anything really useful for getting data out of the IMP format. What I think is wrong (or correct, if you will) is that the files from non-Book Publisher sources are compressed using the LZSS algorithm, hence the reason no human-readable text is available. I draw this conclusion from what I found on the website previously referenced and the fact that the data file holding the bulk of the eBook (data.frk) uses a known file extension. Unfortunately, the few decompressors I found for the LZSS format either a) crashed (very old code) or b) simply did not work.

Not sure where to continue with this other than to use the method I've been using. Thanks for the tip, hopefully someone with more ninja skills than mine will cobble together some for of IMP text extractor.

See Converting .IMP to anything? WE ARE NOW THERE! for a solution to this problem.

There you will find deimp.exe, the text decompressor (extractor) for .imp files which are (LZSS) compressed. It is based on the LZSS source code (lzss-0.6.zip) created by Michael Dipperstein (mdipper@alumni.engr.ucsb.edu). More information on LZSS encoding may be found at: http://michael.dipperstein.com/lzss

The extracted text (with no images/hyperlinks) can then be easily converted by BookDesigner or equivalent.
