[discuss] Writing a MSc, PhD, DSc or a text book in Open office - P1 for Issuezilla

Hi Mathias
 

So this should be explicitely stressed on openoffice.org, that this program
is not optimized for poeple who need to create a document containing
images.
 

No, OO DOES LOAD all images in RAM during start up:
If the images are inserted as a link, the .odt has 600 kB (40 images
and 60000 characters). Opening
of this file under OO takes 20 s (on the first start up and with OO
startup, it takes 70 s all in all) (!!!), RAM consumption rises by 180
MB and CPU consumption is 90 % on average. BUT, saving of this document
is fast enough (3 s under windows, 6 s under SUSE linux 10.1 final),
no significant RAM or CPU consumption.=20
I can provide You the source file without text. I wonder how is it possible
that even a OpenOffice.org Application Framework Project Lead did not
experience this bug.
This problem is platorm idependent, opening uder suse linux 10.1 gives
the same result (RAM and CPU consumption). And again, hard disk speed
is evidently not the limiting link, the limiting link is here CPU (as
a consequence of the bug).

Again,
If the images are inserted as a whole file, the .odt has 15 MB (40 images
and 60000 characters). Opening of this file under OO is fast enough,
and there is no significant RAM or CPU consumption. BUT, saving of this
document takes 20 s (!!!), no significant RAM consumption, CPU consumption
rises to 90 % on average. So, again the CPU consumtion! I have heard,
that OO saves the file as a compressed zip. OO probably compresses these
images before saving - there should be an option for the usere to choose,
if he wants to save the file compressed (my file as .odt has 15 MB)
or uncompressed (my file as .doc has 16 MB). I am sure, that tho most
users appreciate fast saving rather than sparing 1 MB (from 16 MB).

Opening of the same files, but in .doc format, under OO lead to a even
more drastical increase in RAM consumption:
The 16 MB .doc file (40 images and 60000 characters, images physically
inserted) takes 400 MB in RAM (!!!!!!!!), the 600 kB .doc file (40 images
and 60000 characters, images inserted as a link) consumes 220 MB of
RAM.

 

Please try it with my files (.odt, .doc, images saved either physically
or as a link), you will see, that after opening, every image has to
be viewed on the display to be deleted from RAM. Reviewing of the image
on the display does NOT result in increasing of RAM consumption.

 

I am glad to read this, but unfortunately i dont know what API is...
 

Thanks for helping with the priority estimation.
 

I have never heard about OOo2.0.3 IIRC, I just simply downloaded version
2.0.3 and thats all. I would be very glad that someone thought of people
having to work with large pictures in text files..
 

Again, it DOES influence load or save performace, please try out my source
files. I am relatively experienced, so i do know that scrolling through
the document is limited by the disk speed.
BUT, as mentioned above, after opening the mentioned files (.odt where
images are as links or all .doc formats), during the scrolling through
the document and viewing the images for the first time, the images ar
being moved from RAM to the hard drive.

 

Nice to hear it, please let me be the first to try out the fixed version
of OO.

Agree.
 

Maybe Xara Extreme on Linux
 

Its fairly important if you use Impress much. Also it is very important
in the education market. If Draw had proper svg support OOo would be
much stronger in the schools market. Even with Draw and its limitations,
it is a selling point I use quite a lot.
 

Yes, maybe it would be better to replace the Draw engine by an inkscape
engine in version 3. Ok probably too big a job but at some point svg
import export has to be fully supported
 

I can't see it get worse because that could break a whole lot of other
things like Impress presentations and diagrams in Writer.
 

Agree. I have been voting for SVG draw support from the beginning :-)

Maybe just because I didn't have a document like yours. :-)

Believe it or not, OOo normally does not load all images of a text
document when you load it, they are loaded on demand (e.g. for painting
them). If you have a particular document where it looks as if it
happened then there surely is a reason for it (and this reason can maybe
avoided by changing some codeor even is a bug). But this is not the
regular case!

My comment that OOo doesn't load all images was meant as a general
comment because you made a general statement (see the first sentence of
the quoted text above). Of course it is always possible that there is a
particular document where for whatever reason a lot of images are loaded.

Obviously OOo has some performance problems with your document. If
possible please create an issue and attach the document to it. We are
always very interested in fixing performance problems.
 

OOo does not compress images if they are compressed already. And if the
file was saved in odt already the images are compressed anyway. They
will not be saved or compressed again but the compressed stream will be
copied directly from the old zip file to the new zip file.
 

On doc import OOo will probably load all images. I don't know the filter
code very well but I assume that this is the case and hopefully the
developers had a reason to do so. In the worst case just time pressure. :-)

I would see this as something that could be optimized in further filter
development and as we are currently working on the Word filter I'm sure
that we will have a look on that.
 

So there is a special reason in your document. Sounds interesting. :-)
 

Sorry, my bad. I'm so used to some acronyms that I always forget that
other people might not know them. "IIRC" means "If I remember
correctly." So if you have OOo2.0.3 you already have a version that is
optimized for saving graphics or OLE objects.
 

I don't deny that your particular document is a problem for OOo, it's
just not the regular case. I really would be interested in getting my
hands on your documents. If you don't dare to attach them to an issue
you can send it to me directly: com.

Best regards,
Mathias

There are a couple of grammar checkers for OOo. They have to added by
the user. The specific one to install depends upon the language you need
to do your grammar checking in.

You most do it on Draw, OOoWriter doesnt has the transformation modules.

[discuss] Complaint

Posted: 21 Sep 2006 12:27 AM PDT

hi Adrian,

thank you for your reply!

In lyx with gtk backend, one can easily input formula if one is familiar
with latex. And lyx displays the symbol as one inputs, so one can see
whether it is right instantly. I also like inputing formulas by keyboard
because I am familiar with latex.

oO seems like latex, but is quite different, it has its own key words. As
for me, these key words are obscure, In lyx, there is also a formula panel,
it displays some of the keyword by symbols if available instead of English
word,
for example, a fraction, one can easily understand it is a fraction even if
he(or she) does not know English.

Thanks for the info.

The default formatting button would be handy within the styles (F11)
floating toolbox.

Sometimes I don't want to change all formatting to default so this
option is not the best.
