Issues with JPEGs to LRF

shousa · 01-22-2008, 08:16 AM

I have good quality pictures that I have taken of each page in a textbook using a 7.1 MPixel camera, each is about 1.2MB

(thanks to many on this forum for explaining about making a book holder - BTW I used an empty beer carton box with a six-pack of beer in the middle and I ripped off the top short end flaps and folded them as "V" shapes to hold the book in the centre of the carton with its main top long-ways flaps pointing in which all rested on the six-pack inside the carton middle so I could make the perfect holder in 30 seconds!! Problems occur with this structure when the only beer in the house is in the aforementioned six pack however.....Glass covering main photo of our wedding in frame was used to make each page flat.....I like living on the edge as well)

I have saved them as similar .jpg files without a visible loss of quality so the files take around 250KB.

Trying to convert them to LRF for the Sony Reader (I am waiting on its arrival) I have found the right settings to make a single PDF of them using JE Comics - the images are still good at this point.

I have tried pdf2lrf.exe with no settings and the resulting LRF makes the text badly blurry and totally illegible.

I also find that capacee's PDFLRF, with no change in settings, does the same.

Considering my page shots seem good to me I am at a loss how to get these onto my Sony Reader as I have exhausted all the options I could find.

Anyone got any ideas

The 505 will view your pictures without the need to convert them to LRF or PDF. Just load them onto the reader and view away.

Does the Sony 505 support directories though?

If it doesn't what naming convention should I use to keep multiple books in order?

If I wanted to go to page 100 is it possible or do i need to go thru them all?

I ask because I am doing a massive amount of organising now so that when it finally arrives (505) I will be able to use it immediately.

Alphabetical works.

So for example for my Japanese for Busy People book I guess JBP1 - 001.jpg, would be the way to go?

I still would like to know if I have many books as JPEGS is it hard to get to page 100 of the 5th book, for example?

I had a diredtory of 100 Jpegs so i converted to PDF and then it created one file!
which worked fine on the 505 as a single book a lot easier to read.

I tried that already (see the first post above) and could not get it working good enough.

Could I ask you to tell me how you got good quality doing that?

Haven't done this yet but I would suspect that if you make your JPEG images the same resolution as the reader you're using, you should get better results. Having very high resolution images (higher than the resolution of the reader) just wastes memory storage.

I did not think of that - thanks.
