I don't think you have answered my question.
|
|
<BR>
|
|
<P>The zoom factor alters the size of the image, which is not very helpful.
|
|
<BR>
|
|
<P>The point I was trying to make is that xsane should, in Copy mode, scan
|
|
<BR>
|
|
at the most efficient for the type of printer copying to. Efficiency
|
|
<BR>
|
|
in quality and printsize. Perhaps in the Copy options, you need to add
|
|
<BR>
|
|
the type of Printer, b/w, 8 bit colour, etc.
|
|
<BR>
|
|
Copy of Binary is at printer resolution.
|
|
<BR>
|
|
Copy of Gray to b/w printer is at third printer resoloution, otherwise
|
|
<BR>
|
|
at printer resolution.
|
|
<BR>
|
|
Copy of colour to b/w printer is at third printer resoultion gray scale,
|
|
<BR>
|
|
otherwise at printer resolution.
|
|
<BR>
|
|
<P>The reason is that if I want to use my scanner/printer as a photocopier,
|
|
<BR>
|
|
two minutes to Copy is far better than 20 minutes. The only way I can
|
|
<BR>
|
|
achieve the desired effect is to specify the printer resolution as 200dpi,
|
|
<BR>
|
|
and to use Gray scale.
|
|
<BR>
|
|
Using Binary at 600dpi printer resolution produces a poorer copy, and a
|
|
<BR>
|
|
slightly bigger file (8.2MBytes against 7.3Mbytes)
|
|
<BR>
|
|
Maybe using a reduced printer resolution is a workaround, but xsane
|
|
<BR>
|
|
should do the hard work and work out the optimum.
|
|
<BR>
|
|
<P>Incidentally, next to the Start button the following is displayed
|
|
<BR>
|
|
4960 px x 6983 px (33.0 MB)
|
|
<BR>
|
|
While I guess 4960 px is 4,960 pixels, what does the 33.0 MB stand for.
|
|
<BR>
|
|
It is not the filesize or printsize as I first assumed. I guess you mean
|
|
<BR>
|
|
33.0 Mpx (for Mega pixels). However, I suggest it would be more useful
|
|
<BR>
|
|
to show the size in Mbytes of the file, print or fax that will be created.
|
|
<BR>
|
|
<P>Regards

|
<P>Hi Harry,
|
|
<BR>
|
|
<P>1)
|
|
<BR>
|
|
if you use the copy mode of xsane you can not set up a resolution for the scan.
|
|
<BR>
|
|
In the preferences menu you set up a resolution for the printer. If you use the
|
|
<BR>
|
|
zoom factor 1.0 that is the same, if you use zoom factor 2.0 the scan resolution
|
|
<BR>
|
|
is the double of the entered printer resolution.
|
|
<BR>
|
|
<P>If you entered "600 dpi" for the printer resolution all scans are done with
|
|
<BR>
|
|
600*zoomfactor dpi
|
|
<BR>
|
|
<P>2)
|
|
<BR>
|
|
the printfile always is a postscript file and that uses about 2 bytes for each pixel
|
|
<BR>
|
|
because the image is given in hex code. If you print a png file with "lpr test.png"
|
|
<BR>
|
|
the png file is converted to postscript and the postscript file is much larger than
|
|
<BR>
|
|
the png file!
|
|
<BR>
|
|
<P>Bye
|
|
<BR>
|
|
Oliver
