World: r3wp

for example line

you mean non rectangular windows directly in rebol view kernel?

some place where is drawn something

but that would not be sufficient for drawing app as well ... dunno 
what such routines are based upon, but it cant be magic, no? :-)

just have to know what is shape and what is (event) transparent:)

but it should be done in Rebol internally. not that I will make images 
from all drawings and check if it's transparent or not under my cursor

IIRC Tao Intent has such capabilities, you can decide upon alpha 
channel even, so your events could be transparent etc ... well, that 
could be coded too, no? you just press mouse, you detect position 
of your press, and decide what is under the mouse - that is the most 
difficult part imo ...

I think cyphre have some simple examples how to do this but... it 
should be in Rebol internally:)

Paul Nolan once told me, that the most capable compositing engine 
he saw was Shake: http://www.apple.com/shake/- look at features. 
But Carl once told me, that View uses kind of "nodes" too or something 
like that, simply that View has some advanced compositing too ...

(well, except the blitting :-)

Rebolek's AGG demo called "Cyphre" reminds me a bit of Tempest 2000 
- anyone planning on a Tempest 2000 clone ?? :)

Hello folks  ^^

Here is a little somthing i was working on some month ago when the 
 Ritchtext edit  topic pops out -> RTE ...

the code is ugly but tiny there is some bugs but i think the idea 
is good  ^^

shadwolf, well, it's a start :-)

i will be really glad if  some AGG guru could have a look on this 
script and modify enhace it and maybe make a tiny lib  ^^

what we need for text  to begin is bold/italic/underline/normal/color 
 If you have 10 more minutes to pend on it  images  would be a plus 
 ^^

Henrik yes ... hum i guess you  didn't see this script runing lol 
it looks like I was drunk when i wrote that  lol

my main idea was to use draw and use a cursor /input output similator 
but i'm not really a specialist in that kind of motion

hiya shadwolf.. also working on something similar in the past.  Never 
finished it though an alpha for flounder is still on the website.

As  all of us i use premade stuff included in over priced C libraries 
 for "prfessionnel"

icarii can you past url of this project here this will allow ppl 
to compare / merge technics ...

http://rebol.mustard.co.nz/projects.htm

I'm intending to move flounder to AGG when i get a spare moment

by extension i was planing this to be once a short and full working 
solution will be found to insert it to RebGUI as a basic widget  
of this set  ^^

uses draw at present but not many differences

nice idea for widget

but u know ... hen u are drunk  you have full ideas then the next 
morning on wake up you read back the code and  "Hoooooooo damn ... 
was is this ?? i made it  ?? no serrious that can be ... What does 
all those lines are supposed to do  ???"

hehe

Shadwolf -> Drunk Coder .....  hum not all the  time but this time 
yes  ..

Hey Shadwolf ... don't miss Ashley's message to you in RebGUI channel!

done  ^^

but then i have a abnormal bug witch means nothing ...

how can a widget in external context mode works better than a widget 
internal context mode

having the same strict code lol

Founder-a4 with rebol/view 1.3 ** Script Error: Invalid argument: 
+
** Where: view
** Near: show scr-face
if new [do-events]
>>

i have looked long time ago at rebconsole code ... but without understanding 
it mutch ...

that's probably because the script was written for view 1.2.48 i 
think

Are the AGG bugfixes part of View 1.3.2 ?

what was particularly fixed in agg? can svg work continue?

Svg  works need a dubeged matrix  -> scaling problem  and  gradients 
that feet ratio  information and   not  fixed area  ^^ those things 
can be script coded but this will complicate the SCV rendering engine 
and makes it slower for nothing ...

SVC = SVG

Those are exactly the questions/request, which I would expect to 
be answered by RT

iirc Cyphre said some fixes will be mady ... such features are not 
fixes though, so we can only hope ...

shadwolf - have you put your request into rambo?

Shadwolf: the matrix problem you had should be fixed in DRAW 1.3.2. 
The gradient ratio parameters will be added probably in the next 
release.

I'll post resume of AGG fixes/improvement very soon in this group 
so you are informed.

I'm trying to isolate a possible bug having to do with 'line-pattern 
.  I don't think using a negative number should cause rebol to lock 
up the CPU
