pen trail as object (in OLPC)

I was revisiting this issue - wanting to have my drawn pen trail become an object, and I dug up this post: http://article.gmane.org/gmane.comp.lang.smalltalk.squeak.squeakland/869Are these directions still basically true for the OLPC etoys, i.e. do I need to resort to writing a textual script? thanks, Randy _______________________________________________ Squeakland mailing list [hidden email] http://squeakland.org/mailman/listinfo/squeakland |

Hi, If you just want a pen trail as an object, an easy way is to use the lasso,available from the object catalog/ category graphics. Object catalog is the first button of the objects flap(icon box on the right). move the lasso around your trace, to make the background transparent, use either the paint halo of the sketch or or halo menu/painting.../erase pixels of color..

There is an other solution. Use a lineMorph instead of penTrail. Get object catalog from box flap. Get a line in category graphics. get an ellipse The line has a category polygon in the script viewer You'll find there all you need for creating a new vertex, putting it at the position of the ellipse. move the ellipse and create a new vertex, put it at the position of the ellipse ... and so on The line is the wanted object and has the wanted shape ! Here are the scripts for getting a circle.

Thank you once again for your reply, Pierre-Andre. You helped provide details of what Alan had earlier suggested, I think. I must admit I still find it a bit confusing. I basically repeated your project - using a Line and Circle from the Graphics category of the Objects Catalog. However, I could never change the pen size of the drawn polygon. Is it not possible using this approach? Similarly, I tried to change the color - both the penColor (pen use category) and in the color category, but could not. -Randy On Sep 8, 2007, at 5:37 PM, Dreyfuss Pierre-André (EDU) wrote:

Replying to my own post, I did finally discover that I could use the 'fill & border' category of my Line/Circle-constructed polygon object to increase its "pen size" (borderWidth) and color (borderColor). However, it really is a different type of object than one created via painting, isn't it? E.g., in my case, I created a closed polygon and then would have liked to "fill" it using the paint bucket in the paint palette, however, their is no Repaint handle for my constructed polygonal object. Neither does the Line's color tile in the fill & border "fill in" my closed polygon. Perhaps for the project I had in mind, I'm better off returning to the original suggestion of normal painting with the trick of "erase pixels of color". -Randy On Sep 8, 2007, at 7:49 PM, Randy Heiland wrote:

Hi,
if you are using the line object way, you get a line object with the shape of the trail. It is no more a trail painted by the object. This means that you have to change the properties of the line object. To change the color of the line, either use the color halo (magenta)or the line's borderColor tile (category fill & border ). For the width, use the line's borderWidth tile (category fill & border ). See the example project http://ofset.org:8000/super/uploads/Olpc-polygones.003.pr Regards -------- Message d'origine-------- De: Randy Heiland [mailto:[hidden email]] Date: dim. 09/09/2007 01:49 À: Dreyfuss Pierre-André (EDU) Cc: Squeakland list Objet : Re: RE : [Squeakland] pen trail as object (in OLPC) Thank you once again for your reply, Pierre-Andre.

Since the Line is tracking the Circle's pen movement, set its width to the Circle's pen size and its color to the Circle's pen color. The pen of the Line object is not used in this case because the Line itself represents the visible part of the trail. Hope this helps ..

Hi, Randy,
Load updates in an eToys2.1 image, then look in the "pen trails" category of a playfield's viewer...

Scott, I'm not following you. First, I *think* I've updated my latest image, but that itself seems more challenging than the old etoys (where, I seem to recall, there was a 'help' in the main menu that would update from the server). Now, it seems, I use the main menu to go to the Prefs where I can set 'updateFromServerAtStartup'. Regardless, I'm now using etoys2.1 #1565 However, when I open the "pen trails" category of a playfield's viewer like you say, all I see are tiles for clear, lift, lower, and trailStyle. Nothing that would seem to help me turn the pen trails into objects. -Randy On Sep 11, 2007, at 12:27 AM, Scott Wallace wrote:

Hi, Randy,
You've got to be at update level 1610 or later to see the changes. If you're operating with "eToyFriendly" turned on, hit cmd-shift-W to get the "world" menu, where you're then find the familiar "help" submenu that will allow you to load updates.

Ah, excellent! (don't you sleep, Scott?) Thanks for the tip on the world menu (or, reminder, if I once knew it :). Now, sure enough, there's a handy 'penTrailGraphic' tile in the playfield's "pen trails". -Randy On Sep 11, 2007, at 6:10 AM, Scott Wallace wrote:
