File size for part II submission

Is there a limit on filesize for part II submission? Any tips on how to deal with large images? I am using Rational Rose for modeling and RoseGraph for extracting the diagrams as JPG images....they are too big!!

Hi,
To finalize my diagrams I was using Rational XDE which also
outputs JPGs.
I believe that JPGs are meant for photos etc. They give poor compression
for diagrams. It seems that for diagrams you do much better with PNGs or
GIFs.
Initially, as I was using Windows (no choice with rational XDE), I just
loaded my diagrams with Paint and saved them as GIFs. This makes for a
dramatic improvement. I'm not sure if Paint does PNGs.
After I finalized the diagrams, and since my jar was still a bit big (<800K)
I switched back to Linux and used the GIMP to convert the GIFs to PNGs. This
saved another 10 to 20 percent.
I'm now planning to upload (whenever they sort this permission problem) my
630K jar.
Sun's comments on the file size are a bit strange. They say that > 1M has
caused problems for people uploading, so try to keep to 200-400k (by
optimizing graphics).
Hope this helps.

Rich.

Hi,
I emailed to complain about lack of permission at 01:33 this morning (GMT +2:00).
I had already seen your message and Chris' response, so I also sent the message to 'Correspondence'.
In addition I sent it to the Sun contact I had in the UK.
I was worried, because my Part III exam is booked for tomorrow. I assumed that I had to upload the assignment before the exam.
But my Sun UK contact tells me that I can do the exam before uploading the assignment.
I've had no response yet from the US about permission.
But when I had an earlier problem, Sun UK's prompting seemed to speed things up in the US.
If you're not in the states maybe you should contact Sun where you are.
Regards,
Rich.

Hy,
I made screenshots of my diagrams, and then saved them as .JPEGs - you can adjust the copresion rate from 90%-70% percent, what will make your diagrams smaller than 20-45KB each.
I wouldn't use any other formats than .GIFs or .JPEGs, as they must be put into a HTML page, and these are the 2 widely supported formats for browsers.
Greetings,
Rudi

Hi,
I had no problems with PNGs in any of the browsers I tried - Netscape 7 & IE 6.0 on Win XP Pro,
and Mozilla (whatever version comes with Red Hat 7.3) on Linux. But none of these is very old.
However these diagrams don't depend on fancy PNG features, and according to a PNG resources site there has been support in the main browsers since 1997.
Anyway, unless you want to squeeze that last few percent out of your images GIF should be fine.
Rich.

Just out of curiosity how did you get such a large file size :
I had jpeg images (did not convert them to gif/png),
total images : only 9.
How many do you have ?
Apart from this only html files...
I am using Rational on Linux, but that shouldn't matter ...

If that question is for me it will have to wait till I get back.
I'm just walking out the door for the part III exam.

I have 12 diagrams.
I have 7 sequence diagrams. I have a diagram with my own version of the domain
model, a main class diagram, a supplementary class diagram, and a component
diagram. I also have a separate navigation diagram for the JSP's.
The largest are the sequence diagrams. These I drew at the smallest scale
that was readable. Some of the others I could have made smaller - but I was
satisfied that they fitted on a page OK.
The largest sequence diagram in dimention is 1630x1620 pixels, but with just
a little scrolling it seems pretty readable. Maybe I'm too influenced by my
quite hi-res 1600x1200 screen.
The largest file size (another sequence diagram is 91k)
I have about 90K of HTML commentary and assumptions organized into a few
documents. This might well be over-the-top .
Rich.
P.S. The part III exam wasn't too bad. We'll see when they sort out letting me upload the assignment.

I am also using Rose with RoseGraphics. Make sure you export it in a GIF format. It will save you A LOT of space!

I have another question somewhat related to it. I am all right with the file size. But my diagrams are so big (most of the time horizontally), only half of them can be shown in the browser without scrolling bar while keeping them readable. For main class diagram and most of the sequence diagram, they have to use scroll bar to see the whole picture. My question is, is it going to be an issue for the grader? Anyone who uses Rose and RoseGraphic please share your experience.
 
Don't get me started about those stupid light bulbs.
