Hi there, Fernan.
Thanks for your comments and bug report concerning the EPS export; and I'm sorry it has taken me so long to reply to this - life was a little busy when you posted to the list.
You have raised a number of interesting points - so I've just commented on each one :
I'm trying to prepare a figure using Jalview, and as per the
instructions, I'm activating the wrapping in the alignment, and after
removing columns to the left and right of the desired region, and
resizing the jalview window to obtain a nice alignment (I'd like to
have blocks of ~ 60 columns) and then printing to a .ps file, I find
that the output is always wrapped at the same column (residue 71 of
the 1st seq), no matter what I do.
The only way of getting close to what I want is by altering the
margins when printing ... which doesn't give me a good control to wrap
my alignment exactly where I want ...
Could you send me an example where this is happening ? As far as I can tell, the wrapped EPS export seems to honour the displayed wrap width in the alignment window, but it does have its limitations. The layout algorithm is fairly simple (it's 'nearly' the same one as used on screen), and doesn't 'posterise' the alignment; that is, it doesn't span a block of rows vertically over multiple pages. This may be what's causing you problems.
Other issues I've noticed:
* when printing I have to select the largest possible paper otherwise
the output is truncated. In this case I've chosen A3 paper for
printing. It'd be nice if jalview offered a custom paper size
The page setup box is from the standard Java printing system, and these settings are only relevant when you are sending data to a printer; Jalview doesn't use them at all when you export to an EPS file.
If your printing device supports it (ie using Adobe Distiller or some other kind of virtual printer), then you should be able to set a custom page size. But, you normally have to delve into the OS printer configuration dialog, and my brief experiments on windows XP suggest that the settings that you change in the dialog that appears after pressing the 'Printer..' button on the Page setup dialog are not carried over to the Print dialog (which is also pretty annoying - since you have to set the printer again, and check that its custom page definition still exists and is selected).
With regards to your comments above Rather than simply offer a custom paper size, it actually sounds like you want a 'fit alignment to paper' (you specify paper and jalview scales). Alternately, you might want jalview to try to 'fit paper to alignment' - that is, selecting a paper sufficiently large to fit the alignment with the current rendering settings.(jalview produces EPS with custom bounding box).
* It'd also be nice if we could specify a % enlargement/reduction when
printing, so we that we could avoid tweaking font sizes, and just say
50% when printing (belvu supports this nicely). With jalview the only
way of reducing the output is by changing the font size or later by
editing the ps file in inkscape or illustrator.
Jalview was originally designed to be strictly WYSIWIG, and one of the reasons that we introduced the multiple view mechanism was to enable different font sizes to be chosen for the same alignment diagram. The workaround would be to press 'ctrl+T' to duplicate your current view, and then change the fontsize. However, I agree that having a scale factor setting in an 'export layout settings' dialog would be simpler.
* when trying to print again to a file, I need to specify the path and
name of the output file. When trying to print again in the same
session, using the same file (i.e after changing something, like when
resizing the window), jalview opens the dialog sitting at the default
dir (it forgets the previous path) and I have to navigate *again* to
the my current workdir. After 2-3 times, it gets annoying to repeat
this.
This sounds like an issue with your installation, since the last viewed directory should always be remembered - even after you close Jalview and re-open it again. Can you follow the instructions on the faq about getting the output of Jalview's StdOut and StdErr (the java console output - http://www.jalview.org/faq.html#reportbug ) and send me the contents of the console after you try to save your file a few times ? This should help me diagnose the problem.
Hope this helps! And thanks for a great piece of software!
Thanks! You're very welcome...
all the best.
Jim.
