View 1 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]

Sep 3, 2011I'd like to draw an image (like a bar code) pixel-by-pixel in a Visual Basic .NET WPF Application and ...
show the image in my UI
copy it to the clipboard
save it as a .BMP-File.
It should also be possible to add Paint-like editing features later.What is a good approach? System.Drawing.Bitmap works internally, but the only way I could show it is to convert it to an ImageSource and show it inside an Image control. Is there any better way?

May 25, 2009I have the following code found on internet:

Const WM_CAP_EDIT_COPY = WM_CAP_START + 30
'The first step is to recognize that the video captured by the web cam can be saved as individual images. By displaying a series of continuous images on the client, it is similar to watching a video stream. To capture an image, I have defined the following subroutine:
'---save the video data into the Image global variable---

View 3 RepliesVS 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.)
