Png vs Jpg

Hi :)

Yes, true.  Png is 'lossless compression' whereas Jpg is lossy but Png is still 
compressed and Gimp can set the compression rate.  

Jpg often introduces strange artifacts (like ripples or the wake from a boat) 
which can inflate file-size!  You see this a lot on badly done logos or images 
that have been manipulated while being jpgs (eg heavily cropped and re-sized),  
I have seen Pngs suffer a little at extreme rates of compression but Jpg 
compression is far worse  even at low levels of compression.  

There are some clever ways of reducing Png sizes so that they can compete 
favourably with Gifs for things like logos and simple stylised images.  I've 
seen very light Pngs that have very low colour range. say only 2 or 3 colours 
and no shading or blending.  The corresponding jpgs have been very much heavier 
and looked messy whereas the png stayed clean.

Regards from
Tom :)

Kind of hard to say not knowing how much is text and how much is mages, but 
for the less comples images, .png is far and away the best way to downsize 
image sizes by setting the number of colors appropriately and finessing the 
other settings like transparency OFF, etc..

"Definitions of png format on the Web:

  a.. Portable Network Graphics (PNG) is a bitmapped image format that 
employs lossless data compression. PNG was created to improve upon and 
replace GIF (Graphics Interchange Format) as an image-file format not 
requiring a patent license. It is or spelled out as P-N-G. ...
  en.wikipedia.org/wiki/PNG_format "
  b.. Do NOT use NOF to adjust image sizes; use an image editing 
application. My favorite is PaintShop Pro as it allows previewing file sizes 
of the various web image formats.

IF statement linking external sheet error

I'm having trouble migrating certain files to LibreOffice from
OpenOffice containing IF statements to external sheets.

The following IF statement works fine in OpenOffice, but but results in
Err:504 (Error in paramter list):

=IF(('file:///home/figueroa/Documents/da/enws/enws2011/enwssumm_hs.ods'#$Sheet1.$E$17)=1,1,0)

However, the following reference to that file works fine:
='file:///home/figueroa/Documents/da/enws/enws2011/enwssumm_hs.ods'#$Sheet1.E1

This error only occurs in combination with the =IF statement.

I'm running under Gentoo.  This has been tested and verified after
installing the program from binary and source.

I don't know if this is a real bug, or if I need to set something to
make this work right.

Can anyone using Ubuntu/Debian 32bit verify my findings in Comments #10
and #11? If so, or find that 32bit .deb installs work for you, can you
please assist & contribute your findings to the bug report? Thanks

Can't get spell check to work.

I am using libreoffice 3.3.1 linux binaries. I have spell checking
working one machine, but not on two others (one of which has never
had openoffice on it). If I try to spell check something on those
machines, I get an immediate "The spell check is complete" with no
errors (even if I typed complete gibberish).

The language selector in the spell check dialog box is blank, and
the dialog box disappears immediately so I can't change anything.

If I start typing gibberish, the first letter does get changed to
a capital, so I know that at least some part of the language tools
is working.

Any idea about what is causing this?

I added my comment.
However, I'm not sure if the failure on my system (parallel 
installation, but the program just does not start) comes from the same 
source as the problem you reported.

Re: Can't get spell check to work.

Hi :)
Do you get the same issues if you install the pre-compiled versions?  Are the 
.deb and .rpm's not viable for your machine?

Which OS are you running?  Bsd, Slackware, Arch?
Regards from
Tom :)

There are perfectly good .tar.gz files available. :)

Linux (as I mentioned before) - custom built from
source. Besides libreoffice (not worth it for me to
compile from source), there are fewer than five
packages on each machine (out of roughly a thousand)
that are pre-compiled binaries.

I am using LibO_3.3.1_Linux_x86_install-rpm_en-US.tar.gz
on the machine with a thirty-two bit operating system,
and LibO_3.3.1_Linux_x86-64_install-rpm_en-US.tar.gz
on the machine with a sixty-four bit operating system
(neither of which spell check is working on).
