You can install the connect reader software and use that to see how the files look. Basically the fonts look like they've been reasterized without any antialiasing.

Uhm, I don't have access to a Windows PC at home ... so if you could post some screenshots I'd be grateful. But yes, the fonts do look a bit ragged ... what happens is that I render at 300dpi (anti-aliased), perform dilation at that resolution and then reduce the size. Now, as a result of this anti-aliasing happens with the reduced image, which is bad because when you downsample it to 4 colors you can get "gaps" where the color information is lost due to the 2-bit grayscale limitation. As far as I know, even RasterFarian has pretty much the same output. Can you try with that and see how good the result is?
BTW, can you try again with 1.7? I replaced imagemagick with pngnq, this may give better output... Last edited by ashkulz; 04-27-2007 at 12:49 PM. |

1.7 fixed the problems I was having, now works like a dream. Thanks

Okay, I'm planning to release 1.8 in a day or two. The major feature planned would be an all-color pipeline (with option to downsample to grayscale, of course). This won't be of much use to anyone except people who own the REB 1200 (ie. me ) and those who get those newfangled color e-ink readers.
Some previews of things look in color: raw page, dilated page, and after color reduction. Regular text pages also work as they used to: raw text page and the dilated text. Do any of you have any feature requests for 1.8? I don't feel comfortable with such short releases where only a few new things are added ... |

I used your batch file and changed the batch file conversion directory from "My Desktop" to another drive on my computer. It works! I guess there might be some restriction of user access issue involved, but I am not sure about that.
Some files are converted with no problem, others are still with this annoying "unable to determine total number of pages" problem. I later find that those files that cannot be converted include: 1. pdf files with OCR text underneath the image, 2. pdf files with non-alphabet file names. Hope it can be dealt with in later releases. |

I manually put in the page number and it encountered the decoding error. I've posted the command line error info below and also attached the zipped directory and problematic file.

If you ensure that fonts are embedded in the PDF and the filename doesn't have special characters, it should convert properly. |

Hi people.
ashkulz, you did a great job ! I've been using 1.6 and I quite like it. The install is just perfect. The prs-500 mode is good, and prs500-l is very nice too. Maybe GUI isn't totally clear the first time, and it misses the .lrf extension on my files, but otherwise it rocks One thing: why add "title" when there is "output" field ? When you fill output name, shouldn't it be auto copied in title ? Good job ! Please keep it up. Last edited by Jary; 04-29-2007 at 05:59 PM. |

Thanks ashkulz! I'll convert the filenames to fit utf8 encoding. I've batch converted a dozen files overnight and it turned out quite well.
