primax: Thread: compression algorithm ....

Hallo Christian
hallo linuxhacker-crew,

please let me write german, it's not so heavy for me.

Ich habe einen Primax Colorado Direct 600 am Parallelport des
Druckers Lpt1 (EPP). Single-PC mit SuSE Linux 8.0

Trotz eifrigen Suchens mit Google und viel Lesens im ListenArchiv
kann ich mir folgende Fragen nicht beantworten und bitte Dich deshalb
um Hilfe wie folgt:

1) Welches nachstehend genannte Programm wird
zusammen mit Primax (Parallelport) verwendet ?:

Gimp - Sane - Xsane - Gocr - Clara - Kooka

2) Welches Programm sollte ich neben
Primax_scan-0.93beta3.tar.gz auch installieren ?:

Primaxd-0.5.tar.gz
PrimaxGUI-0.99-9.tar.gz (falsche Version ?)

3) Wird mit Primax das Modul pt-drv benötigt
und wenn ja, wo finde ich es ?

4) Bei mir ist u.a. installiert:

libxml, libxml2, libxml2-devel, libtiff

5) wieselsdachsbau:~ # rpm -qi libtiff

Name        : libtiff
Version     : 3.5.7
Release     : 60
  [. . . ]
URL         : http://www.libtiff.org/
Summary     : Tiff Library (with jpeg and compression support)
Description :
To link a program with this libtiff, you will have to add
-ljpeg and -lz to include the necessary libjpeg and libz
in the linking process.
[. . . .]

6)  wieselsdachsbau:~ # primax_scan -ljpeg -lz

Looks like a Primax Colorado Direct

7) Beim Aufruf von primax_scan leuchtet die Lampe
des Scanners und der Sannvorgang beginnt. Alsdann
werden folgende Fehlermeldungen ausgegeben:

wieselsdachsbau:~ # primax_scan
primax_scan.tif: LZW compression is not available to due to Unisys patent enforcement.
primax_scan.tif: Compression algorithm does not support random access.
[. . . .]


Wenn "libtiff" daran Schuld ist, was muss ich in libtiff ändern ?

Nach Abschluß des Scannvorganges erlischt die Leuchte nicht.
(Auch nicht beim Ausschalten des PC's)

8) Beim Konfigurieren von primaxd erhalte ich
diverse Probleme:

a) Es wird nach makeinfo gesucht, habe ich aber nicht.

b)  /usr/local/etc/primaxd-conf.xml wird nicht geschrieben,
obwohl ich manuell /usr/local/etc/ angelegt habe.

c) Beim "make" werden folgende Fehlermeldungen ausgegeben:

wieselsdachsbau:/usr/local/primaxd-0.5 # make

9) Was habe ich falsch gemacht ?
Wo finde ich Info-Material auch für den späteren Gebrauch von Primax
unter Linux ? (Ich kenne unter Windows "Tbridge, Twain, MGI, Iris")

Ich bin nur einfacher User (kein Admin). Es wäre schön, wenn Du
das berücksichtigen könntest.

Für alle Hilfe im voraus meinen herzlichen Dank.

Schöne Grüße
Siegfried

Gimp: is only for Image manipulations ... like Photopaint(Tm) or Photoshop(Tm)
SANE: is a scanner framework like TWAIN under Win

the other stuff you mentioned is unkown to me ...

this is the original scanner program by Marco, Thomas and me. There's
no need for any further program in order to scan with your scanner.

is a SANE backend by Andre Herms. It's based on an earlier version of our
primax_scan ... and is a standalone project not depending on primax_scan,
but needs SANE.

PrimaxGUI is a frontend for primax_scan to make scanning much easier.
it has its own version numbering. This program is recommanded for use
with primax_scan

the -ljpeg and -lz are command line parameters for the compiler/linker ...

To see the parameters of primax_scan type primax_scab --help

yes. that's a problem. Newer versions of libtiff don't support LZW compression
anymore. 
use primax_scan -C 0 to switch off compression.

Could you please send the output of ./configure.

Yes, I did understand.

After you told me, how it works, all is really nice and easy.

Now I could scan a picture. All right. Thank you.

Primaxgui is installed and I'll learn to work with it.

But when I scan yet a document with primax_scan -C 0,
the quality of the tiff is badly. What can I do better for it ?


salutations

Siegfried

could we see such a bad image, you mean? -C 0 should not change
the image quality, it's only for (not) compressing the raw data.

Best solution would be posting only an URL here, where we can watch
such a picture ... if you're really forced to post the picture here,
please compress it using gzip or bzip2.

Hi Christian and all,

sorry, can't give you a URL.
gzip-compressed file of a document-picture you get here.
The original is the lilo.conf (567 B)
The gzip and the *.conf I send only to your Email, Christian.

ok. it seems you use the default resolution of the program for 
scanning ... -r 300 should give really better solutions ...

Hi Christian

hi all,

that is indeed so, I did use the default.
All other I must learn first. Therefore I need some time.
Once again many thanks for all your help.

I think, afterwards I come back with questions
for fax with primax. But not today.

Best salutations
Siegfried
