World: r3wp

since version 03 I have changed the way to handle svg content but 
I don't inserted the transformation support in those lastest version 
(04 and 05) My other problem is how to suppoer localtransformation 
information and global one. So transformation informations are attached 
to a group and some other are attached to a draw primitive so How 
to represent it to AGG code

My other problem is about gradient effect

how to convert SVG gradient information to AGG one to make it simplier 
SVG use vector information x1  X2 y1 y2  they use a list of color 
with there position along the  vector ( from 0 to 1)  and they encap 
transformation information too So how to translate this to the fil-pen 
gradient linear exploitable issues

so to resume transformation informations are Global (attached to 
a group of drawable primitives) local (attached to a drawable primitive 
and attached to gradient in defs)

sorry I make a mistake the code with the matrix support is http://shadwolf.free.fr/svg-demo-shadwolf02.r

Is there a mode for backwards compatibility with old draw ? eg. (lines 
are not anti-aliased, but simple jagged)

antialiased of ...

but many drawable primitivs have keep the same name but takes other 
arguments

and others doesn"t exists :)

I have inserted the matrix transformation into my new code

I'm near to the solution

'arc takes radius argument as a pair! but 'circle takes radius argument 
as two decimal! - I think it's inconsistent

'arc is consistent with 'ellipse !!!

It is, however you can think of circle usually taking only one number 
to be the radius.

It's a handy alternative to ellipse (I haven't tried ellipse) which 
allows you not to need to use scale.

view layout [b: box navy 100x100 effect [draw [circle 30x50 19.5 
20.2 circle 60x50 19.5 20.6]] image b/size * 4 to-image b]

You can see the two ellipses are slightly different.

yes I understand, but when there's such a precision with cicrle, 
why it's not same with 'arc?

you can get it using    scale 0.1 0.1    for example.

sometimes it's handier with pair!s, sometimes it's handier with pairs 
of decimal!s

OK, but I still think that 'arc, 'circle and 'ellipse should have 
radius parametr in same form.

pair! with decimal precission would be nice

Ah, but that's the thing... :)

Adding a new datatype is a major extra body of code. And with SCALE 
we really don't need it.

I know I know, it was ust a small dream ;)

but still - I think that 'arc, 'circle and ellipse should have same 
type parameteres

for radius

I've just found in the documentation that 'arc in 'shape uses two 
decimal!s and not one pair!. And now tell me it's NOT confusing :)))

Circle fill and outline don't seem to match up quite perfectly.

img1: to-image layout/tight [image 40x40 effect [draw [pen black 
fill-pen leaf circle 20x20 19]]]

img2: to-image layout/tight [image white 40x40 effect [draw [pen 
black fill-pen leaf circle 20x20 19]]]
view layout [image 200x200 img1 image 200x200 img2]

You can see some light green pixels at top left of the outside of 
the circle, and at the bottom left, on the inside of the circle.

I wonder if this is a rebol agg implementation issue or an agg issue.

I believe that's a known issue Anton.

Yes, known issue.

ok, so I assume Cyphre is on to it already.

Shadwolf, you will find it much easier to work from this style:

do http://www.lexicon.net/antonr/rebol/gui/demo-direction-pointer.r

Anton, yes, this is known issue. This will be fixed in the next version.

Anton:

Shadwolf: I analyzed your SVG example with nested MATRIX command 
and found little bug in matrix calculation. Thanks for pointing this 
out! I know the solution so it will be fixed in the next Rebol View 
build.

Note: The bug is related only to MATRIX command. TRANSFORM/TRANSLATE/ROTATE/SCALE 
works ok.

Dide, I think it failed to load direction-pointer.r file. Just try 
again until it works ! :)

Hum, your script search for the file in our Rebsite index.r file, 
so I must see it in the Desktop, isn't it ?

If yes, I see a %direction-box.r, but no %direction-pointer.r icon.

No. It is not indexed. Actually, quite a lot of my scripts are not 
indexed :-(

(but I am working on that).

Sorry but tried 20 times and still the error

It works at home :)
I wonder why it didn't at work!

Cyphre Great !!!! I'm happy to have found a difficult bug regarding 
MATRIX in AGG/DRAW :) I hope this will be solved as soon as possible. 
I all cases tahnk you to have take the time to scout my problems 
:)

mmm weird :)
