Re: [Opensvgviewer-general] Cleaning done.

Hi Marco and Miguel,

Here in SIG Lab we all apreciate your good work and interest for the
project. Now i will write some considerations in portuguese.

Desde já axo que a ideia de dividir o projecto em três partes é boa, na
medida em que me parece aceitável separar o desenvolvimento da interface
gráfica do desenvolvimento do parser. A 3ª parte é a junção das outras duas
para funcionar em PDAs (penso ser esta a vossa ideia).

No entanto, e dado que voçês estão a pensar usar Java2 no vosso
desenvolvimento, quero alertar para o facto de que o objectivo deste
projecto é mesmo as plataformas móveis, porque já existem vários
visualizadores de SVG "livres" (por exemplo, o Batik da Apache) que suportam
toda a especificação SVG e que usam as mais recente tecnologias Java mas não
funcionam nas máquinas virtuais de Java para as plataformas móveis. Daí, o
nosso interesse maior é que o projecto avance para o funcionamento em PDAs e
é aí que nós precisámos mais da ajuda da comunidade científica mundial :)
pois o nosso conhecimento nessa área ainda é limitado.

Entendo perfeitamente quais a vossas intenções visto que o mais importante
serão os algoritmos usados na programação, mas queria que não se desviassem
muito do objectivo principal do projecto e que também contribuissem (sempre
que possível) para esse objectivo, que é por a funcionar decentemente o
visualizador em PDAs..

Continuação de bom trabalho.

P.S.: Temos de marcar uma reunião para discutir ideias e soluções. Pode ser
pra semana? (Esta pergunta é pra todos os envolvidos no projecto... :))

(Viewer/). The reimplementation of the svg parsing and DOM construction will
be started in a new tree (gvsj/). Both these trees will be coded for, and
using, the most recent technologies. That means Java 2, including the use of
Java 2D and the most recent Java libraries. The objective is to do a
complete implementation of the Mobile SVG's Basic profile. These trees
should be merged sometime in a not distant future.

1.1 platform. With that objective, a third tree (gvsj-fly/) will be created.
The  purpose of that tree is to change the code in the other trees to make
it work in Java 1.1. Of course that doesn't mean we will have to change all
the code from the other trees, but, instead, to create the necessary
libraries to substitute the ones not present in the Java 1.1. It would be
nice if someone steeped forward to manage this tree. Anyone interested? This
task will not be very difficult: we, all, will be careful when choosing the
code to use in the other trees to make this task of porting an easy one.

> For now, the development process should _not_ be closed. One option would
be to have a maintainer for each tree that would accept patches from the
other coders; no one else would have write access to the CVS tree. This is a
good way to maintain a big project or one that is already in stable state.
As we want to develop as fast as possible, and we sure are not big yet, the
'open access' is preferable.

application. It must be copied to the directory '../icons' relative to the
location of the code. That is, the directory containing the code should be
sibling with the directory 'icons'.

the original developers. Many lines came out, but we trashed some
functionality in the process. To maintain the same functionality as the
original code we would need, for sure, at least... lets say... 4444 lines of
code. So, they are not as bad as they seem, looking just to the numbers.
