[Nook Touch General] nmyshkin:
OK. Perfect Viewer.

It reads CBZ, CBR, PDF (not so good), image files (JPEGS, etc.).

Almost anything you read is better in landscape because most items like comics, magazines, PDFs of anything, are too small when scaled to the device screen in portrait. Landscape just about brings most items to a readable size and avoids zooming and panning.

There are pre-configured tap zones on the screen (you can change these in Settings):

center = bring up main menu from bottom of screen

left = page back

right = page forward

bottom = quick menu (you can customize in Settings)

Let's look at the quick menu settings for a minute. Go to Settings from the bookshelf (the "tools") and scroll down to "Quick bar customize" (next to last). It looks like PV6 below. We're going to add "Adjust color" to the quick bar which already has the items shown in the lower part of the screen. "Adjust color" is something I use a lot to "clean up" some comics I get which are not such great scans (always go for filenames with "digital" in them if you have a choice).

So you select "Adjust color" from the options in the top half of the screen (you have to scroll to get there). PV7.

Then you tap on "add" at the bottom of the screen (PV7) and you will see "Adjust color" listed there (PV8). Then you can move it around in your list if you want. PV9.

OK, let's get out of Settings and open the file I sent you. Tap on the item in the bookcase. It's not a great scan, but we can use that to explore the controls a little. First, notice that the cover and all the pages take two "page changes" to move off the screen. That's pretty typical. It's also true in landscape although there the cover takes 3 changes because there is no cropping so the page is a little larger.

Move to the first page of the actual comic (p. 3 or 4). PV10. It's hard to read because it's so small. Tap on the bottom of the screen to open the quick bar and select the "rotate" control. PV11. That places the document in landscape mode (the bookshelf and the device itself, if you exit Perfect Viewer in this state, remain in portrait). Now it's more readable and still only takes two "page changes" to flip to the next page. PV12.

But it's sort of a poor scan. The paper was probably already discoloring when the scans were made. One of the great things about the app is the ability to make brightness, contrast and gamma changes. That is done with the "Adjust color" control we just added to the quick bar. PV13, PV14

You have to learn by doing here and each situation will be different. The background is kind of "dirty" so I might try raising the brightness a little and raising the contrast also to compensate. The gamma affects the overall image in a way I can't quite describe.You can try moving it below 1 and see what happens, then try above 1. Eventually you may find something you like. PV15. These changes remain until to do something else, so don't be surprised if you open another document and it looks terrible. You probably need to reset the Adjust color controls.

That's only a very brief intro to Perfect Viewer. There are MANY settings to play with. If you have a question about anything when you start using it, you can always ask.

Like the Kindle app and EBookDroid, Perfect Viewer requires a manual cover capture when you're on the cover of the document (long-press lower right hardware button). This will place the cover image on the home screen and tell the "reading now" button and the cover image to take you directly to the document, bypassing the bookshelf, etc.
