Invalid scanned images
« on: November 05, 2012, 16:54:11 »
Hello,

I'm on Linuxmint 13 (MATE)
I have a Samsung SCX-3405FW. It is connect to LAN (for printing/scanning from other PCs) and USB to my PC.
I configured my system to the repository, so I guess I have the latest version.
But anyway, scanning is working fine, for example with the "simple scan" program installed.

But I wanted to use command-line.
scanimage -L gives me this:
device `smfp:SAMSUNG SCX-3400 Series on USB:0' is a SAMSUNG SCX-3400 Series on USB:0 Scanner
device `smfp:SAMSUNG SCX-3400 Series on 192.168.1.28' is a SAMSUNG SCX-3400 Series on 192.168.1.28 Scanner
So, first question: is there a way to make these names shorter (like without spaces, for instance)?

Then, options are also very long:
scanimage -A -d 'smfp:SAMSUNG SCX-3400 Series on USB:0'
mfp_claim
mfp_release

All options specific to device `smfp:SAMSUNG SCX-3400 Series on USB:0':
    --preview[=(yes|no)] [no]
        Requests a preview-quality scan
  Image Quality:
    --mode Black and White - Line Art|Black and White - Halftone|Grayscale - 256 Levels|Color - 16 Million Colors [Color - 16 Million Colors]
        Sets the color composition mode of the scanned image
    --resolution 75|100|150|200|300|600|1200|2400|4800dpi [300]
        Sets the resolution of the scanned image
  Scan Area:
    --page-format Statement - 5.5"x8.5"|Statement (Rotated) - 8.5"x5.5"|A5 - 148x210 mm|A5 (Rotated) - 210x148 mm|B5 (JIS) - 182x257 mm|Executive - 7.25"x10.5"|A4 - 210x297 mm|Letter - 8.5"x11"|Legal - 8.5"x14"|Folio - 8.5"x13"|Custom [A4 - 210x297 mm]
        Sets the paper format of the scanned page
    -l 0..216mm [3]
        Sets left position of the scan area
    -t 0..355mm
        Sets top position of the scan area
    -x 0..213mm [210]
        Width of scan-area.
    -y 0..355mm [297]
        Height of scan-area.
    --doc-source Auto|Flatbed|ADF Simplex [Auto]
        Selects source of the document to be scanned

Here again, would there be any possibility to make them shorter?

But anyway

So, to scan I have to give the whole 'smfp:SAMSUNG SCX-3400 Series on USB:0' as device (with simple quotes).
For example:
scanimage --format=tiff -p -v -d 'smfp:SAMSUNG SCX-3400 Series on USB:0' --mode='Color - 16 Million Colors' --resolution=100 --page-format 'A4 - 210x297 mm' > test.tiff

This gives me a (2.9MB) big file. But it seems that it is invalid.
If I try to convert it I get:
convert test.tiff test.pdf
convert: Not a TIFF or MDI file, bad magic number 26221 (0x666d). `test.tiff' @ error/tiff.c/TIFFErrors/496.
convert: missing an image filename `test.pdf' @ error/convert.c/ConvertImageCommand/3011.

And if I try to open (double-click) this test.tiff, I also receive this "Not a TIFF or MDI file, bad magic number 26221 (0x666d)" message.

And if I try with pnm format:
scanimage --format=pnm -p -v -d 'smfp:SAMSUNG SCX-3400 Series on USB:0' --mode='Color - 16 Million Colors' --resolution=100 --page-format 'A4 - 210x297 mm' >test2.pnm
And then:
convert test2.pnm test.pdf
convert: improper image header `test2.pnm' @ error/pnm.c/ReadPNMImage/289.
convert: missing an image filename `test.pdf' @ error/convert.c/ConvertImageCommand/3011.

And opening it gives also an error.

So, I am not really sure if this forum is the right place to ask this question.
But I guess that some people here may have ideas, at least where to search for more information.

Many thanks in advance.
