VS 2005 : Drawing Shapes In A 2d Image?

May 25, 2009

i am creating a winform program using vb where i am loading an image into a picture box. then in the mouse down event i am creating small circles which can act as points which will be displayed on the image. say creating five points around the eye of a bird. then i am having a button by clicking it , a polygon will be drawn on those selected circles x and y as edges. i am having no issues until this. when i am trying to add another polygon in the same picture by clicking around its leg or whatever and pushed the draw button there must be another polygon i.e. two separate polygons 1 on eye and 2 on leg. but there is only one polygon from eye to leg. so my questions are

1) how to close a polygon and draw another one in picture box

2) how to select a previously drawn polygon and delete it.

picturebox_mousedown
Private Sub PictureBox1_MouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles PictureBox1.MouseDown

Using Loop To Draw Different Shapes

May 25, 2011

I want to use a loop to draw different types of shapes on a visual. I want to use the Random function sothat the number of each shape would be set randomly. For example, I want three triangles followed by two circles, followed by two triangles, etc. When you click the button again a different set of shapes would be rendered. I can draw shapes. What I need is how to use the loops and Random() to do this. I tried to use concatenation but it does not work with the Polygons.

VS 2010 Drawing Circles, Rectangles, Elongated Shapes?

Apr 20, 2012

I would like to draw a rectangle on a form, for example to mimic a steel beam that is 6 metres long.Within this rectangle, there may be 4 "openings" or circles that mimic a diameter of 600mm, so i need to draw 4 circles within the rectangle, to indicate a beam that has 4 openings. Other issues I need to cater for is that one of the circles may not be in the centre, it may be slightly raised.The user can change the length of the beam and the size of the openings so i'd like to refresh my drawing to keep in line with this.

Drawing On Picturebox Vs Drawing On Form?

Feb 18, 2012

I need some code to draw a resizable, draggable rectangular cursor (or selection box) on a picturebox. I found some excellent code (albeit rather old) that does just that, but on a form rather than a picturebox. I have tried converting the code - basically moving things to the picturebox events (Paint, MouseDown, MouseMove etc). It nearly works but leaves a trail behind it when you move or resize the cursor. In other words, the selection rectangle is not being erased before being drawn in the new position.

Is there some fundamental difference between drawing graphics on a form and drawing on a picturebox that would cause this behaviour? Something like, when you invalidate a form and cause a redraw it erases what you did last? If not, then I just need to dig a bit further and work out how the cursor is being erased from the previous position.

Here's the original code that works fine on a form:

Private DragRect As New RectangleF(20, 20, 100, 80)
Private Adornments(7) As RectangleF
Private MouseInRect As Boolean = False

[Code]....
