World: r3wp

Yes, that works. Great, Anton!

anton:  WRT license,  (I had found that one  ;-) this only tells 
you that a pro license is installed... not the components which it 
enables...

since components of the pro package have changed from one version 
to another... its getting a bit tedious to hope everything is properly 
mapped...

and we aren't talking of other obscure packages like dll, link, sdk... 
for which I have no clue what is enabled.

I tried to create with the following code a circle with a transparent 
background and save it. I tried some different versions, but currently 
I have no glue how to achieve this. The point is I need a file with 
a circle and a transparent background :-) and I thought I quickly 
do this with Rebol instead of using a paintprogram. So am I doing 
something wrong ? It's saving the background from the window and 
if that is set to 'none then it's black ?

view layout [
    b: box 22x22 effect [
        draw [pen red line-width 2 circle 11x11 10]
    ]
    across 
    f: field 200 button "Save" [
        file-name: to-file f/text

        unless find/last file-name ".png" [append file-name ".png"]
        save/png file-name to-image b
    ]
]

There is some rebol-XXX? words and one is 'rebol-pro?
>> help rebol-
Found these words:
   rebol-command?  logic!    false
   rebol-encap?    logic!    false
   rebol-link?     logic!    false
   rebol-pro?      logic!    false
   rebol-view?     logic!    true
   to-rebol-file   native!   Converts a local

Seems pretty recent (almost 1.2.48, not in 1.2.8)

MichaelB, maybe you wanna something like:
i: to-image b
repeat n length? i [t: i/:n t/4: 255 - t/1 poke i n t]

i: make image! 22x22
i/alpha: 255
draw i [pen red line-width 2 circle 11x11 10]
save/png %test.png i

component? might be another one to try.

Gabriele, much better than my solution! :-)

Thanks Gabriele, didn't even know that draw is a function which can 
be used stand-alone. (thanks to Geomol of course as well :-)

Im getting all the time the same errors from /view 1.3.2.3.1 anyone 
kows if thats a known problem?

** Script Error: Invalid path value: dirty?
** Where: evt-func
** Near: if all [
    system/view/focal-face
    event/type = 'down
    not within? event/offset win-offset? system/view/focal-...
>>
>> unview
>> system/version
== 1.3.2.3.1

It always happens during events with the mouse.. like drag and drop 
up/down while dragging out of the window etc..

Maybe you use custom faces not based on 'VID-face but on 'face object, 
so there is some "properties" missing in your faces.


This code is from the global event handler and handle field/area 
loose of focus :

	 probe system/view/screen-face/feel/event-funcs

View set system/view/focal-face to editable face only (field, area).

So if you use it for other type of face that did not have 'dirty? 
property ==> Error!

The exmaples are from the new /view doc ;-)

But ill fixed it by baking my own... But now i have system crashed 
useing 'merge as effect...

What example?

Well strangly enough it doesnt always happen.. i was testing from 
this document -> http://www.rebol.com/docs/view-system.htmland example 
10.4 Iteration Example

 does crash.. probably an minor error somewhere... did not check it..

But it have to be said once agani once every year ;-) "Rebol Rules" 
;-)

Seems to work OK here.

Are you sure you don't have any special things in your %user.r file?
It's usually a things to check.

Well now you mentioned it.. I had a look and its stuffed with 'Steel 
configurations.. Let me remove those ;-)

Who created the Images in the document http://www.rebol.com/docs/view-system.html
 ??? I mean the Data-flow images...can the person in question please 
contact me ;-)

Because I wonder if they where made with the draw dialect? If so 
then i would like to know how.. Im unable to immitate that effect...

I think they were from Carl or his son. Just a guess. Non-rebol.

dideC:  thanks!

steel !!!  wow that's a long time ago!  ;-)

When does this happen -->

** Script Error: Not enough memory
** Where: wake-event
** Near: show main

?

Im using Layout where im appending panes into layouts.. But i dont 
think thats the problem... The problem is resizing an 'effect to 
negative numbers... like a box from 0x0 500x500 to ->  -50x0 -100x100 
...and only using it in the Engage event... Odd?? anyone an explanation 
perhaps ? This is Linux /rebview from SDk262

>> ? system/stats
SYSTEM/STATS is an integer of value: 6544927

Sorry !!.. i dont use layouts in this exmaple...onyl 'faces

Sounds like a bug. What is the effect block which shows the error 
?

By the way... Is there any news on the Right Text Formatting inside 
Rebol? Will it be in? or is there a special project for RTF ?

AFAIK RTF is ready, but I'm afraid we have to wait for R3 :/

owww oke.. well yes I have read the concept from Carl in his Blog.. 
So thats probably then also the release that will be inside R3.. 
..oke lets wait..

not only concept, but Cyphre has also code ready, only it's not integrated 
in View :/

I would really like to see that roadmap .... and discuss it here 
- what waits for the new branch, and what goes into 2.x .... VID 
is still incomplete and misses some show-stopper styles like grouping, 
tabs, drop-down is ugly like hell

Yes "roadmap"... We are all very currious regarding a roapmap and 
status indicator of all the running projects.. I have asked Carl 
if it would be possible to publish sush an indicator for the public.. 
It seemed a good idea to him...so lets wait and see if that can bring 
us more insight ;-)

don't be so inpatient. as Carl said on 3rd March and Gabriele on 
14th March, roadmap is just couple of days away.

Im not waiting for anything Im still trying to understand all of 
rebols concepts.. so i enjoy the time being ;-) New releases are 
always a surprice to me..Its like a small gift in a box when that 
happens.. ;-)

:)

Question regarding 'draw and 'face..

What is adviced .. Im currently creating faces what will later be 
stored as pictures i.e. PNG.. 

No should I start already using an IMAGE and draw on that or create 
faces and draw on that?


Im not sure what is more efficient in relation to flexibilty of creating 
images regarding delete and create of faces inside faces or creating 
/ deleting images from/inside images..

What is the application to do ?

(by the way, RTF = *Rich* Text Format)

yes thanks.. Im a blind Horse on my new keyboard..sorry..

coming back to the question.. In both cases of my program the output 
will always be an image.. so should I start drawing already on an 
image of should i use faces and convert those to an image?
