Is Pocketbook working on this font anti-aliasing issue?
They are busily working on a new firmware. To me this thread sounds like adding a few software enhancements concerning font anti-aliasing could bring the PocketBook's look-and-feel to a completely new level. I don't understand, why PocketBook hasn't yet fixed it. I would understand, if they had a new generation of Pearl-devices coming - competing with older devices in terms of display quality. But since PocketBook is still using those Vizplex-screens, ameliorating display quality with this piece of software should be the most intelligent thing to do...?! |

I was thinking about something. Since it's a linux OS, would it be possible to use Wine and then install some excellent PDF viewer as PDF x-change viewer (who would win easily the legibility contest again Adobe viewer or others) ?

Finally, the reader display is much lower resolution than ink on paper, and much lower contrast than even a computer screen. Fonts in PDF files are generally designed for ink-on-paper, and look pretty bad on E-Ink. I don't think any program is going to get around this problem. I guess a program could just increase the stroke size when rendering fonts to make them look bolder, but that could make letters overlap unless the kerning is changed, too. Changing the kerning will likely cause changes to the number of words on lines... There is no easy fix except to hope for higher resolution/higher contrast E-Ink displays someday. |

I have opened the same PDF in the two viewers on my PC to illustrate my idea: I don't use Aobe reader anymore as for me due to this problem. And it's the same for all the PDF but maybe more on certain types of PDF (the example here isn't a scanned document). Last edited by Huyggy; 11-12-2011 at 02:10 PM. |

Have you looked in the Preference->Display menu for acroread? It looks to me like maybe you have font smoothing disabled.

I don't think so. Here's my preferences.You can try too to view this PDF (at 50% zoom for example)

That test.pdf file just contains an image of text in it. So, PDF x-change just uses a higher quality image scaling algorithm than acroread. This has nothing to do with font rendering. You can try to extract the image from the PDF file and viewing it directly on your ereader to see if the image viewing software scales it better than the PDF viewing app.

The picture viewer of Pocketbook is really cheap (But at least the pictures and fonts are clear...) : one fixed level of zoom, you can't change pages after zooming, accelerometer is turned off automatically (!), etc. Last edited by Huyggy; 11-13-2011 at 12:15 PM. |

Is there no way to adjust the brightness and contrast of individual files like in sony's prs readers? When reading PDFs with my sony reader, I usually customize the contrast to +40 and brightness to -40 -- generally works best within the range of +-30 to +-50. This way, the text is sometimes rendered even better than my hard copy of a book/paper.
--- update: never mind my asking. I reread the first page only to find out that there is no way to adjust the contrast. I thought that such option (brightness/contrast) would have been so very EASY to add. Last edited by carlitoernesto; 11-15-2011 at 02:51 AM. |

You can adjust contrast on epub files only with Cool Reader3.

I agree, but perhaps this is a hardware issue. Maybe the Pearl screens can adjust their brightness and contrast, but the earlier technology can't. It's hard to understand otherwise how to fine-adjust the contrast on a device with 16 shades of grey. Does anyone know such details? My old PRS-505, which seems to have the same E-Ink technology as the PB devices, can't adjust brightness/contrast either.

WINE is an acronym that stands for Wine Is Not an Emulator. Both Linux and windows binaries run on the same Intel x86 compatible processor on PC. The "only" difference is, that Linux binary and Windows binary (exe program) have different format of the beginning of the file and different file organisation and that they require certain services from underlying operating system. Services like access to the filesystem, library calls ... . But the underlying machine code tht actually runs on processor is essentially the same. PocketBook runs on different type or processor. Freescale if I remember correctly. Even Linuc programs can not be run very easily on PocketBook. They have to use special [not very well documented] libraries to access hardware, such as e-ink display. So software must be re-written - ported to PocketBook system and compiled for special type of processor PocketBook readers use. |

don't want to raise my hopes too high, but i just read on the Ukranian forum that in the next 2.1.3 firmware they will include the possibility to adjust contrast in pdf files!
