TITLE Print a Graphic to a Printer
OCCURRENCE ARB_NT/Tree/Print Tree
ARB_SECEDIT/File/Print structure
DESCRIPTION Multi Page Printer
SECTION Select what to print
Clip at Screen: Show only those graphics that are
drawn at the ARB_NT main window
Show Handles: Show/Hide root and mark symbols
Export colors: Whether to export colors or not.
SECTION Page Layout
The upper part of this section shows the current graphic size,
the magnification in effect, the resulting outputsize (after
resize) and the used papersize.
graphic size: size of graphic in inches. When you change the display
while this window stays open (e.g. zoom in/out ...)
press <Get Graphic Size> to update the graphic size.
Magnify%: magnification of graphic. This can either be set manually or
will be set automatically by changing the number of pages used.
Papersize: useable paper size in inches (i.e. size of area printer can fill)
Normally you will select one of the predefined paper formats.
Doing this will pass it to fig2dev (which is used to preprocess
printing).
It is also possible to use non-standard-formats by setting the paper
size directly, but since they aren't known by fig2dev figuring out
magnification, overlap etc. might be tricky or impossible.
Orientation: Landscape or Portrait mode
Bordersize: Keep an empty border around the graphic (specified as percentage of
graphic size)
Useable size: How much of a page your printer can fill. This is used when
calculating the 'Papersize' from paper format.
This value cannot be influenced by ARB, it's only here to
allow you to inform ARB about the capabilities/restrictions
of your printer setup.
SECTION Multiple pages
Left side shows the fractional number of pages needed to print with
current magnification and orientation.
Fit on XXX pages:
- shows the number of pages which will be printed
- change it and click on 'Fit on' to zoom the graphic such that
it will fit on the specified number of pages (that will
modify 'Orientation' and 'Magnify%')
- mark lock to fix the number of pages used. You will not be
able to change magnification when locked.
- the small buttons below allow to quickly fit onto the
displayed number of pages.
Overlap: If checked, the printed pages will "slightly" overlap.
Does not apply when printing to a single page - obviously.
Note: ARB cannot influence the size of the overlap-region,
but it needs to know it in order to be able to properly
calculate the needed magnification.
If the default of 10% does not match your system, you'll
have to test it (use preview for that). Once you got a
working value, save properties to store it for future
sessions.
SECTION Destination
- Printer: Use print command to print
- File: Use File Name as destination file name
- Preview: Print to file and show using gv (ghostview)
SECTION HOWTO configure correct overlap
The following actions need to be performed in order!
First you need to determine the 'Useable size':
- set bordersize to 0%
- select a graphic which is very tall (i.e. does not fill the complete
width of a page when magnified to fit on one page)
- Fit on 1 page
- select Destination 'Preview'
- now change 'Useable size' until height fits best
- control whether this value is also correct for width and/or landscape. It
is important, that you do NOT use multiple pages when checking this.
Determine whether your fig2dev has the overlap bug:
- disable overlap bug
- print on 2 vertically arranged pages in portrait mode with ~1.99 rows
of pages
- if there is empty space at top of printout and some info is clipped
at bottom, your fig2dev has the bug
Determine the overlap value used by fig2dev:
- switch to landscape mode
- print ~1.99 rows of pages
- adjust overlap percentage until it fits best on two pages
- check value with ~2.99 rows and ~3.99 rows
- check value with portrait mode
NOTES The default printer used by ARB can be defined by setting the
environment variable PRINTER to your printer name.
To change the proportion between font- and graphic-size you have to change the
physical zoom factor (of the radial tree/secondary structure). For dendrogram
and IRS tree the physical zoom will also affect the relation between
horizontal branch length and vertical branch distance.
EXAMPLES Print a long list tree:
1. Select tree style in ARB_NT main window
2. Select File/Print tree
3. Select Destination 'Printer'
4. Press PRINT button
WARNINGS Printing cannot be stopped
BUGS None
