[AGG] to discus new Rebol/View with AGG
older newer | first last |
Oldes 23-Nov-2005 [653x2] | 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 | |
Pekr 23-Nov-2005 [655] | 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 ... |
Oldes 23-Nov-2005 [656] | I think cyphre have some simple examples how to do this but... it should be in Rebol internally:) |
Pekr 23-Nov-2005 [657x2] | 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 :-) | |
Graham 28-Nov-2005 [659] | Rebolek's AGG demo called "Cyphre" reminds me a bit of Tempest 2000 - anyone planning on a Tempest 2000 clone ?? :) |
shadwolf 5-Dec-2005 [660x5] | 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 ^^ | |

Henrik 5-Dec-2005 [665] | shadwolf, well, it's a start :-) |
shadwolf 5-Dec-2005 [666x4] | 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 | |
ICarii 5-Dec-2005 [670] | hiya shadwolf.. also working on something similar in the past. Never finished it though an alpha for flounder is still on the website. |
shadwolf 5-Dec-2005 [671x2] | 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 ... | |
ICarii 5-Dec-2005 [673x2] | http://rebol.mustard.co.nz/projects.htm |
I'm intending to move flounder to AGG when i get a spare moment | |
shadwolf 5-Dec-2005 [675] | 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 ^^ |
ICarii 5-Dec-2005 [676x2] | uses draw at present but not many differences |
nice idea for widget | |
shadwolf 5-Dec-2005 [678] | 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 ???" |
ICarii 5-Dec-2005 [679] | hehe |
shadwolf 5-Dec-2005 [680] | Shadwolf -> Drunk Coder ..... hum not all the time but this time yes .. |
Graham 5-Dec-2005 [681] | Hey Shadwolf ... don't miss Ashley's message to you in RebGUI channel! |
shadwolf 5-Dec-2005 [682x6] | 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 ... | |
ICarii 6-Dec-2005 [688] | that's probably because the script was written for view 1.2.48 i think |
Rebolek 6-Dec-2005 [689] | Are the AGG bugfixes part of View 1.3.2 ? |
Pekr 6-Dec-2005 [690] | what was particularly fixed in agg? can svg work continue? |
shadwolf 7-Dec-2005 [691x2] | 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 | |
Pekr 7-Dec-2005 [693x3] | 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? | |
Cyphre 9-Dec-2005 [696x2] | 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. | |
Josh 15-Dec-2005 [698x4] | 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 |
Submitting to RAMBO | |
(Warning, this will lock up whatever instance of rebol you are running it in) sp: 0 b: layout [ c: box 400x400 white effect [ draw [ 'pen 255.23.23 23.255.23 'line-pattern 1 sp 'curve 50x350 200x50 350x350 200x300 ] ] button "boom" [sp: sp - 1 show c] ] view b | |
I don't know why someone would use a negative number, but this shouldn't happen if they do | |
Geomol 15-Dec-2005 [702] | May be a hard thing to check for without hitting performance too much, because of the late binding in REBOL. I can live with it. |
