Adobe Reader Mobile 9.1 beta

As you might know, quite a few ebook readers run Adobe software. While this software is commonly referred to as Adobe DE, ti's actually Adobe Reader Mobile 9. (The PRS-505 might be the exception. It's old enough that it might be running an even earlier generation of software.)

A couple weeks back a contact with one of the device developers said that their reader was running not RM9, but RM9.1.Naturally, I wanted to know about the improvements, so I followed up with Adobe.

Here is some of what I learned:

Improved Dithering

Dithering is a step in the process by which the reader software takes a color image and displays it. RM 9.1 now provides the code to do this, so device developers no longer have to do it. Text rendering was also improved.

dithering (Wikipedia)

Accent-agnostic searches

The search function will ignore accent marks. For example, if you search for facade, the previous search would have missed façade.

New APIs for link enablement

What Adobe actually added was link disablement. Most ebook readers do not have a web connection, so an external link (to a website, for example) is of no use. The new code will give developers the option of having that external link appear as text, not a link.

Support for password-protected PDFs

According to the FAQ, RM9 already supported this. But is listed as an improvement, so I include it here. This support is only for PDFs created with Acrobat 7 or before. Acrobat 9 is explicitly not supported.

We supported PDFs with a "permission" password, but not an "open" password. We now support documents with an "open" password. In addition we also added support for AES-128 (first supported in Acrobat 7). We did not however add support for AES-256 (first supported in Acrobat 9).

Most ebook readers that use Adobe software for their epub rendering have odd page quirks. First off, 1 screen isn't equal to 1 page. Due to this, you can have more than one page on a screen at a time, and these pages have their page numbers marked on screen on the right hand side. Really kind of annoying.

I like it. Especially how sony's reader displays it in a rather fine, unobtrusive font and manner.

Still it definitely needs to be configurable. I cannot understand why eBook reader device software remains trapped in the stone age of software design and development. Slow screens don't necessitate idiotic 1970's user experience design.

I don't like it because it sometimes IS in the way, depending on the formatting of the book. I like having my text fill as much of the screen as possible, so many of my books have small margins. When you have the page number overlap with the text, it is annoying. I personally just prefer it to how the LRF and everything else is on my 505, where one page is the same as one screen. Even though I don't like that my 505 shows "129-130 of 290" or something for page status at the bottom of the screen, I can live with that quirk, just let me get rid of the numbers on the page itself.
