ADE Font Rendering Engine?
Hi,
I'm wondering if someone knows which font rendering engine is implemented in the Adobe Digital Editions software, under e-ink readers (bookeen gen 3, opus, and others) or ipad based (bluefire). I guess that under ipad ADE uses the quartz engine via coretext or similar. But what about e-ink displays? Is it CoolType or does it use FreeType? Thank you in advance |

I'd say the font rendering is device-dependent, it's not tied to the ePUB reader (does the iPad use ADE, anyway?)

I think there may be a confusion between the use and function of Adobe Reader vs. ADE.

To the best of my knowledge, the font system is part of ADE in embedded devices. I remember some discussion being done about this on the sony boards a while back, because LRX/LRF books would look different than ePub. Reason for this, is that ADE supplied the kit and kaboodle to show ebooks in the ePub format, and the sony ebooks had to use a completely different renderer.

Hmm... Does your PRS-505, which has the Adobe Reader installed, include an "About"
option in its settings when in epub or PDF? Does it list the version of Adobe Reader that is embedded in your reader? For instance my Ectaco jetBook Lite shows "Reader Mobile technology by Adobe Systems Incorporated Version: 9.1.1" Luck; Ken |

Well, maybe I explained myself in a poor way.
What I'm trying to understand is how Adobe Mobile Reader based e-ink reader are rendering fonts. As far as I understand quartz based software just try to render the fonts - even modifying the original shape - to achieve the best reading performance on screen. Cooltype, on the opposite, tries to render the font to match the final printing result (please correct me if I'm wrong). What about e-ink screens (low res and grayscale)? How fonts are treated in Adobe RMSDK? Tnx |

right the Software Sevelopment Kit (SDK) documentation is a good place to find the answer to your question. The Google results for "adobe reader moble 9 sdk" includes links to PDFs and other resources like FAQ and forums. Luck; Ken |
