dotnet drawing api : Wrap a GraphicsPath around a square draw area
I have a square area to draw on... I have a GraphicsPath that define the region of clipping so the draw occur only on that region The region is one or more circles The problem I'm facing with is drawing a wraped region... I can have one circle falling outside one side of the drawing surface What I need is adding a new drawing area on the opposite side(s) of the drawing surface so the impresion should be like the circle get out on a side and reenter the other Can this be done somehow? Thanks, Crirus
Hi,
Do the math. Intersect two circles with your rectangular region - one circle on one side of the region, centered so that part of it is off that side, and the other circle on the other side of the region, appropriately centered so that the "remaining" part of the circle intersects the region.

Assume you are drawing onto a panel control and wrapping on the xaxis only
1. Create a graphicspath from your cicrcles etc 2. Translate the origin using graphics.TranslateTransform to -panel.width,0 3. Draw the path again 4. Reset the transform I guess follow the same steps to wrap on the y-axis as well. Let us know if that works James -- Create interactive flowcharts, diagrams and UML models with ERM3 at http://www.crainiate.net [quoted text, click to view] "Crirus" <Crirus@hotmail.com> wrote in message news:ejK5fjezDHA.2056@TK2MSFTNGP10.phx.gbl... > Hello > > I have a square area to draw on... > I have a GraphicsPath that define the region of clipping so the draw occur > only on that region > The region is one or more circles > The problem I'm facing with is drawing a wraped region... > I can have one circle falling outside one side of the drawing surface > What I need is adding a new drawing area on the opposite side(s) of the > drawing surface so the impresion should be like the circle get out on a side > and reenter the other > > Can this be done somehow? > > Thanks, > Crirus > > >
Yeah but I dont have any ideea wich circle fall off...I can have many of
them randomly displaced I need an algorithm to do that dinamicaly [quoted text, click to view] "John Hornick [MSFT]" <JHornick@online.microsoft.com> wrote in message news:ghgbCgjzDHA.1840@cpmsftngxa07.phx.gbl... > Hi, > > Do the math.

I have an ideea.. test each circle (location - radius) to see if is less
than 0 or bigger than width and translate the center apropiately and add the translated circle to the path .. :) [quoted text, click to view] "Crirus" <Crirus@hotmail.com> wrote in message news:u7#wixrzDHA.2160@TK2MSFTNGP12.phx.gbl... > Yeah but I dont have any ideea wich circle fall off...I can have many of > them randomly displaced > I need an algorithm to do that dinamicaly > > > "John Hornick [MSFT]" <JHornick@online.microsoft.com> wrote in message > news:ghgbCgjzDHA.1840@cpmsftngxa07.phx.gbl... > > Hi, > > > > Do the math.

It may work but when I have some circles only inside the draw area, that
extra draw is redundant... it is not in visible area..so I think the best way is to test each circle (origin+radius) if fall off the margins and if it does, I just need to add the circle translated a with and/or height of drawing surface... so the missing part will be added on hte opposite visible part [quoted text, click to view] "James Westgate (Crainiate)" <james@nospam.crainiate.com> wrote in message news:emDLsSszDHA.484@TK2MSFTNGP10.phx.gbl... > Assume you are drawing onto a panel control and wrapping on the xaxis only > > 1.

I whould like to have such flag in NET that can wrap a region around drawing
area :) [quoted text, click to view] "James Westgate (Crainiate)" <james@nospam.crainiate.com> wrote in message news:emDLsSszDHA.484@TK2MSFTNGP10.phx.gbl... > Assume you are drawing onto a panel control and wrapping on the xaxis only > > 1.
