Question about Pocket Pro's JPG viewing capability

balduran · 10-21-2009, 12:14 PM

First, I'm very impressed by the Ez Reader's wide range of compatibility and I'm planning to order one real soon.
But before ordering, there's just this one big question that must be answered before finally putting an end to my long journey for the perfect e-book reader, and it is about the JPG viewing capability.

I personally scanned my favorite books which just got too old to keep on the shelves, and this scanned book files count up to about 100. Since they are all in JPG formats, I would really appreciate it if my future reader is capable of viewing JPG files with speed, compared to reading a normal epub. I know I could always convert them to pdfs but it will be a hell of a job

And also, is sequential view possible for JPG files? I mean, do i have to go all the way back to the file selection menu again and again just to go over to the next page?

Finally, is zipped JPG viewable?

I have my credit card standing by and ready to go. All I need your answer plz!

I believe if you open an image, and you hit NEXT PAGE button, it will advance to the next image in the list, alphanumerically.

Alternatively, if you simply take all of the images and zip them up, the device will read ZIP and RAR files, again alphanumerically. So you could open Book1.rar (you might have to rename it CBR, not sure) and you will start page 1 with the first image in the file, then advance to page 2 (image 2).

I tested this with a folder of images, and it worked this way. Unsure about the zipped aspect though. Have yet to test those waters.

Sequential Yes. The Page key steps through the images.
In the correct order, Maybe

The file name must sort properly by (case sensitive) Linux. Windows long names can be problematic.

Recently read only shows the first image selected from the file menu.
No bookmarks AFAIK

I don't have a handy zip collection, but zipping a JPG does not save you much, as it is already a compressed format. (and it takes more processing to unpack, even a tiny amount)

Another option is to see if you can OCR your files.

By the Way. Welcome to the group.

Good luck

Note that Jpg images viewed as images will also be scaled to 600x760 images (40 pixels are reserved for the banner). They will also be rotated for best fit. This is not the case if they are put in an eBook format. Images must be less that 4 Megapixel and large images take a while to display. You do have control over the brightness and contrast of the images if they are displayed as images. I keep them in separate folders for easy access, although separate zip/rar containers would work as well.

I'm confused...Is each book in one JPEG file, or is every page in a JPEG file, thus hundreds of pages (i.e.,files) per book?

Thanks everyone for such specific answers. I think that just about resolves my curiosity.
One last concern is the auto rotation DaleDe has mentioned.
The image files I own are about 933x1400 in resolution. Would these auto-roate too?

Whoa!
What is the file size (unzipped) of each of those?
You are asking the PEz to shrink those down, that takes lots of crunch power if you dont exceed the maximum original file size limit.

Is it too big for Ezreader? The files are only around 120KB each though.

theducks · 10-22-2009, 11:20 AM

I was thinking they would be bigger. No grey scale?
Load time will suffer and you do not get to zoom or reflow text, so if your eyes are still good

the image on the PEz is pretty sharp.
