How To Draw A Line On An Image In A Picture Box
Feb 8, 2006I want to draw a line on an image in a picture box. How do I do? The picture box is placed as the only item in a standard form. The following doesn't work:Private Sub PictureBox1_Paint(ByVal sender As Object, ByVal e As System.Windows.Forms.PaintEventArgs) Handles PictureBox1.Paint
Dim TestLine As System.Drawing.Graphics
TestLine = PictureBox1.CreateGraphics
Dim TestPen As New System.Drawing.Pen(System.Drawing.Color.Red)
TestLine.DrawLine(TestPen, 10, 10, 50, 50)
TestPen.Dispose()
End Sub
The corresponding method for the paint event works fine in a panel, but the picture box doesn't seem to support it. What am I doing wrong?

Draw A Line On A Picture?
Jun 29, 2009I need to draw a line on a series of pictures: I have decompiled a movie file to 1200 pictures. I also have 1200 samples of vector data (coordinates of the line: beginning point, ending point , size of vector (length) and direction (angle)... anything). With these data I want for each corresponding picture to draw a line corresponding to this vector data for instance: picture 550 needs to get a line drawn from point (5,95) ... these are (x,y) coordinates. in direction of 5 degrees from a vertical line and length 55. Visual Basic do that? I understand there will be some work in locating the origin of the x,y coordinate system and telling the program what 'size 1' means...

VS 2008 : Draw Multiple Bitmaps Onto Image?
Dec 26, 2009I want to know if there's a faster way to draw images onto a picturebox based on a list of point.
vb

Dim MyBitmap as New Bitmap("C:MyBitmap.PNG")

Now, This code may be a little sloppy, but I just put it together. The image isn't very simple, but it's simple enough. After about 10 images that need to be drawn, it starts to get slow.What would I need to do to ensure it draws the images faster? If I made the image itself smaller would it make it go faster?

VS 2008 Draw Rotated Image On Graphics Object?
Jun 1, 2010I know that you can pass a Point array to the DrawImage method of the Graphics object to apply rotation, skewing and flipping, but I'm having trouble figuring out how to calculate the rotation. So far I've got:
Dim radius As Integer = Math.Sqrt((rect.Width / 2) ^ 2 + (rect.Height / 2) ^ 2)
Dim dX As Integer = RadToDeg(Math.Cos(DegToRad(angle))) * radius
Dim dY As Integer = RadToDeg(Math.Tan(DegToRad(angle))) * dX
Dim new_upper_left_corner As New Point(rect.X + (rect.Width 2) - dX, rect.Y + (rect.Height 2) - dY)
This is all just off the top of my head so far, I'm not sure if it's right. How do I calculate the other points on the rectangle, and is there a built-in VB.NET method that's much easier? (Apart from Graphics.RotateTransform, which is slow and also rotates around 0,0.)

View 2 RepliesVS 2008 Woodcutting Program / Draw Image & Save Cuts
Jan 27, 2010I'm currently working on a VB 2008 course of Michael Halverson, and I'm stuck at an assignment where I'll have to expand a previous wood order program so customers can add woodcuts to their orderIn the newer program a customer can define 4 coordinates (x & y for startpoint and x & y for endingpoint), after clicking on the button 'Next cut' a line will be drawn on screen (in PanelCuts) with a maximum of ten lines. After finishing, the coordinates must be saved in the order.txt, and when the client re-select the order in the main order program, they can review and adjust / remove the already specified cuts.Right now I'm at the point that the you can enter the coordinates, and the line will be drawn.
- What's the best way to store the submitted cuts, in a Label? array? or something else?
- When the form reloads, how to displays all previous made cuts? Can i count the numer of cuts and with For i = 1 to combined with SelectedItem. Split() ? [code]
