Printing
========
The display options 'No text' and 'No images' affect what is printed.
Printing is always done in Accurate mode.
Landscape printing has no effect when printing as a pamphlet.
Single sided printing
---------------------
all Print all pages
>from - to Print pages from 'from' to 'to'
copies number of copies to print
Double sided printing
---------------------
Double sided printing requires Print setup to be correctly filled in for it to
work properly. (Click setup on the Print dialogue box)
If your printer reverses the order of sheets then tick 'Reverses the sheet order'.
If the paper is turned over by your printer tick 'Turns the paper over'.
Once set you can save these settings.
To control what pages to print you have 'all', the 'from-to' range and the
'start-end' range.
Start-End The start-end range indicates the section of the document to be
printed so if you wanted to make a pamphlet from a chapter in a
document you would set 'start' to the first page in the chapter
and end to the last page in the chapter. If the start end range
is faded then the range defaults to the whole document.
All Print all of the start-end range
From-To The from-to range is used to specify the pages from the start-end
range you want to reprint. Note it will print whole sheets of paper
so if you specify a from-to range of 1-1 you will get both sides
of the sheet printed.
Turning the paper over
----------------------
When you have finished printing the first side you will be asked to turn the
paper over. At this stage you can cancel the printing and print the second
side at another time by selecting '2nd side' in the print dialogue box when
you print it.
To turn the paper over you should ensure that the same end (short side) of
the paper is fed into the printer first so for example my laser doesn't turn
the paper over when it stacks the paper so I need to turn it over ensuring
that the same end of the paper is fed into the printer first.
My old inkjet turns the paper over so I just need to turn the paper round
so that the same end is fed into the printer first.
To clarify:
'Turn the paper round' means move the end nearest you so that it is the end
furthest away from you keeping the same face of the paper uppermost.
'Turn the paper over' means keeping the same end of the paper toward you turn
the paper over so that the bottom face of the paper is now at the top.
The paper needs to be turned the same way whether you print as a pamphlet or
just double sided.
Find
====
Find searches for the word entered either from the current page or from the
beginning of the document. The search text is case insensitive.
Logical page numbering
======================
When viewing a pdf file you may find that the page number on the toolbar Ò0
is different to the one shown on the page. This can occur, for example,
when there are contents pages which numbered separately from the main body
of the document. So, if there are 16 pages in the contents the toolbar page
number would show page 1, and be seen on the page as page 17. To go to page 80
you would have to type 96 into the page selector on the toolbar.
You can make the page selector use the same page number as displayed
on the page by:
1) going to a numbered page of the file...i.e. NOT a contents page.
2) going to the 'Set logical page number' dialogue box (in 'Misc')
3) entering the number displayed on the rendered page.
Speed tips
==========
A page which consists mainly of type 3 fonts (you can tell them because the
fonts are not anti-aliased like RISC OS fonts) can be very slow to render
for example the RISC OS Annual report can take over 20 seconds to render
a page, set 'No Type3 fonts' and the same page can take less than 2 seconds.
Luckily font substitution works for the RISC OS Annual Report but it doesn't
always.
Having the pdf file on a RAM disc can speed some pages up a lot - especially
if the page is filled with Type 3 fonts.
!PDF limitations
================
!PDF can't render fonts that are embedded in a pdf file directly, it tries to
use a substitute RISC OS font. This means that sometimes the text is not
rendered correctly.
!PDF doesn't support polygon path clipping so may get drawings wrong. Selecting
one of the settings on the 'Display menu' may allow you to see what you want if,
for example, some text has been obscured.
If the display from !PDF isn't good enough, you could save the page/document as
postscript and render the postscript file with Ghostview (distributed with
GhostScript).
Dynamic areas
=============
By default PDF will look for memory in application space. This limits the maximum
amount of memory available to PDF to about 28Mb. If you would like PDF to be able
to use more memory you can make PDF use a Dynamic area by setting
PDF$DynamicAreaSize as follows:
To use application space.
-------------------------
Unset PDF$DynamicAreaSize
or
Set PDF$DynamicAreaSize 0
To specify how much memory PDF can use.
---------------------------------------
Set PDF$DynamicAreaSize 64
where value, in this case 64, is in Mb. You choose the value you want.
To allow PDF to use as much memory as possible.
-----------------------------------------------
Set PDF$DynamicAreaSize -1
