    Default Scan2PDF

    I am searching for some program for scanning documents to PDF file, I am using samsung SCX-4300. I tried XSane but the files I get are to big (1-3 Mb). Is there some other application for scanner I don't want to star my Windows just for scan some document.

    You can adjust xsane to make the documents larger or smaller. ... but one pays a price wrt resolution/clarity. The same is true in MS-Windows.

    I don't want to scan to PDF, so I have never tried that procedure. Xsane is customizable, so that
    you should be able to choose resolution and compression. In preferences you can choose the default
    options for save to file.

    I normally scan to png at maximum compression, or jpg, via gimp. If i want a PDF, I convert it later
    on command line and choose options.

    In fact, pdf is the worst format you can choose for scanned images. I would use djvu instead, for
    documents, or png if I want precision or photo manipulation.


    I just scanned an A4 page at 300 dpi, a text document. Here are the sizes:

    -rw-r----- 1 cer users 3766363 2010-08-12 19:34 out.pdf
    -rw-r----- 1 cer users 3747900 2010-08-12 19:35 out.png

    PDF has the same size as the png, so it is using lossless compression, like png. If you use
    "convert" to transform it, the result is different:

    convert out.png out-convert.pdf
    convert -compress JPEG out.png out-convert-jpeg.pdf
    convert -compress JPEG -quality 75 out.png out-convert-jpeg-75.pdf

    and the sizes:

    633644 out-convert-jpeg-75.pdf
    1023123 out-convert-jpeg.pdf
    3770675 out-convert.pdf

    And dejavu, wuich is more complex to get:

    624381 out.djvu
