Re: Brush Tool in iOS
I think because the LFs allow you place single points (dots) on the card that simulate the appearance of paint. Spaces in the point list of a polygon allow you to create discontinuous segments/lines. Without the LFs, you would wind up with a messy close polygon.

Re: Brush Tool in iOS
Hope you don't mind a LC newbie coder question. In the code below, why does the graphic need a linefeed (LF constant)? Or does LF have some other meaning?

Re: Brush Tool in iOS
Hi, Randy. Here's a simple example using a graphic. Just create a new stack, add a line graphic called 'draw', set it's lineSize to 10 then put the following script into the card script. Double click clears the drawing, and each mouseDown starts a new line. :) local sDrawing on mouseDoubleUp set the points of grc "draw" to empty end mouseDoubleUp on mouseDown put true into sDrawing end mouseDown on mouseMove if sDrawing then set the points of grc "draw" to the points of grc "draw" & LF & the mouseLoc end if end mouseMove on mouseUp put false into sDrawing set the points of grc "draw" to the points of grc "draw" & LF & LF end mouseUp On 10/09/2011 23:56, Randy Hengst wrote: Hi All, I've begun playing with the brush tool in iOS… I'd like the users to be able to draw on the screen.

Re: Brush Tool in iOS
Randy, Scott, Any idea as to whether this is an Apple limitation or a LC problem? I imagine it is more likely something that Apple hasn't figured out yet, but I've been wrong before! (smile) Guess my project won't be going forward any time soon. BTW, while we're speculating, have anyone heard of multiple iPads being used? I know that sounds really awkward, but multiple monitors did at one time as well. Just another way of expanding the real estate.

Re: Brush Tool in iOS
Randy, How about the paint bucket? I have an app I'm thinking about converting from OSX to iOS that uses both.
