Resize A Rotated Shape?
Jan 25, 2010
i'm working on a simple 2d drawing application that allows you to draw, move, rotate and resize shapes such as lines, rectangles, ellipses, polygons and so on. My code for resizing shapes works fine, but only for unrotated shapes. Now i've changed the code to work also with rotation but i have still some problems, for example:
I create a rectangle at a specified location (the upper-left corner of the rectangle) and with a rotation around the location. With my code i can only to resize this shape using the top-left, the middle-right, the bottom-right and the bottom-center hot spots. The problem is when i try to resize the rectangle using the middle left hot spot or the other ones. As you can see in this images the problem is to calculate the new location that the rectangle should have after the resize operation.

I've been looking for a simple example to print rotated text, without having to create paths and such, just by applying a temporary transformation to the page. My simple example would be to print "Rotated Text" in a circle patern with the bottom-left corner of the "R" being the anchor point around which the text rotates, something like:
Private Sub Form1_Paint(ByVal sender As Object, ByVal e As _ System.Windows.Forms.PaintEventArgs) Handles Me.Paint Dim poMatrix As System.Drawing.Drawing2D.Matrix Dim poState As System.Drawing.Drawing2D.GraphicsState Dim pfAngle As Single Dim piX As Integer 'x/y position to print Dim piY As Integer Dim poG As Graphics piX = 200

I'm trying to rotate a mirror, which I represented by a line across a specific point. I translated the point of rotation to the center, rotated by an angle indicated in a text box and then translated it back to its original position.
Here is my code :

Dim theta As Single
Private Cntr_X_blu_Mirror As Single = 5

I hope the code is good. The problem I encountered is that the line becomes smaller and smaller as I rotate it. and that's bad! Sometimes it even grows longer [I think when I rotate it in the oposite direction!]
Also, when I rotate it at 90 degrees, the rotation does not resembles a 90 degree rotation. It seems to be inclined at 45 degrees instead!

I have a image with a transparent background. I clone it, rotate it, and save it in a picture box. Works fine (in that I can see the original object overlaid on the background image below it). However, the original unrotated image is also superimposed on the .image layer *with* the rotated one. Try as I can, I can't stop it from appearing.
Curiously enough, if I change the image to non-transparent (a .bmp instead of a .gif, for example), I don't have the problem. Of course, I also can't see the background {:<(

Dim myGraphic As Graphics
Dim m As Image

I'm making a game that needs to hit test a Rect object inside 4 points that basically forms rotated a rectangle. This means I can't use the Rect class's IntersectsWith function to hit test. So my question is: if I have 4 points that creates an imaginary rectangle of any orientation, how can I tell if another rectangle is inside the "fence" so to speak?

I want to make a panel or a picturebox which is vertically rotated by an angle in y-axis. The form's opacity should be 50% but panel opacity should be 100 that is panel should be clearly visible but form should should be 50% transparent.

I 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.)

I'm using some code to enable me to render rotated text with the TextRenderer.DrawText method. (By default, DrawText can only copy a straight forward x and y transform from a graphics object).
The code (C#) is from: connect.microsoft.com. See below for a VB conversion.The code takes a graphics object, creates a device context and copies the transform matrix from the graphics object. It works, but I'd like, also, to set the TextRenderingHint, so I tried:
<DllImport("gdiplus.dll", CharSet:=CharSet.Unicode, SetLastError:=True, ExactSpelling:=True)> _
Public Shared Function GdipSetTextRenderingHint(ByVal graphics As HandleRef, ByVal textRenderingHint As System.Drawing.Text.TextRenderingHint) As Integer End Function And then after the SetClip statement, I place: GdipSetTextRenderingHint(hDC, someHint) This gives me a memory access violation error, so I think I should be using something other than hDC as the argument.
I can get it to work by creating the device context from the original graphics object, and then creating another graphics object from the device context. I then set the hint on the new graphics object. This seems a bit convoluted so I was wondering if it was possible through interop.

I created so many listviews in my project, that im too lazy to add to each listview a resize event with percentages. Is there any other trick, who just scales the columns so as they are?

I'm starting work updating an UI for one of my company's applications and I'm running into a sticky issue. The parent control contains several panels, each of which can be turned on or off depending on user input.
The final panel in the user control contains another user control which gets resizes according to a toggle switch. Essentially, it "opens" up more information.
While the child control (ChildControl) is docked to Fill inside the parent control (ParentControl), when I add height to ChildControl I can't get ParentControl's height to get updated as well. Currently I'm handling the ChildControl.Layout event in ParentControl but I can't seem to reach that code. To resize ChildControl, I'm calling Me.Height += 200 in ChildControl.vb.

I'm writing a program that print images in full page. I.E, I print image on A4 paper, landscape. When I print an image without rotating it (the image IS landscape), the image uses all the space of the page, and is not cropped. it is OK. The print job is about 1.5 Mb. When I print an image WITH rotating it (the image IS PORTRAIT ), the image uses all the space of the page, and is not cropped. it is OK. The print job is about 28 Mb. The images are about 2000x3000 pixels, and stored in JPEG files (about 2.5 Mb each). I suppose that the 28 Mb should be the "uncompressed" size of the picture, and 1.5Mb, the compressed size...
By the way, When I look at the task manager, my application memory usage grows by job size, which seems to be OK. It grows either 1,5 Mb if no rotation is occured, and 25-30Mb when rotation occured.
Since I can print hundreds of image at once, my print queue will grow abnormaly if I need to rotate all

1-When I click on the ''Square'' radio button I want the shape to appear in the image box, then need I only need 1 text box to appear where the 4 side boxes are, this will be where I enter the value of the sides to calculate the perimeter and I also want the area and perimeter boxes to appear at the bottom since I don''t need the volume text box.

I have a project(solution) which aims to lance a Form from a lancer module. On my Form Design the buttons are nice and round. When I go to Run the solution and the the Form is set as startup project, all is OK but when lancer module is set as startup project all buttons change to hard rectangular shapes and rounded corners dissapear (see attachments).

how do you correctly dispose a shape in vb.net ie when you draw a rectangle using the pen function how do I depose it so that it will disappear from the form, for some reason once its drawn if I draw a new shape it keeps the previous one and just overlays the new one and I use shape.dispose, and pen.dispose?

I am using VB 2008 for this little first game I am trying to make. Currently a grid of rectangles is being generated when a button is pressed and when you click on the grid I am attempting to import the relevant image into the selected rectangle. Looking through the available options I can't find anything relevant to import the image onto that selected rectangle. Is there another method of importing onto a code generated grid? my current relevant code is: brackets, its my first time here.)
If Form1.MousePosition.X < rect.Location.X + rect.Width And Form1.MousePosition.X > rect.Location.X And Form1.MousePosition.Y < rect.Location.Y + rect.Height And Form1.MousePosition.Y > rect.Location.Y Then

I am working through my Visual Basic Book 2010 book and came across this Program example:Create 3 classes that inherit from a base class named Shape. The Shape class has an instance variable that is the name of the shape and also a CalcArea() function that must be overridden by each subclass. You will need to create the following 3 classes and use the formulas provided to calculate the areas.
Square � Area = sideLength * sideLength
Circle � Area = pi * radius * radius (use Math.Pi for the value of pi)
Triangle � Area = � * base * height
Each subclass should have a constructor that you use to set the name and the attributes required to calculate the area with. Each subclass should also override the CalcArea() function that is provided in the base class Shape. They will also need to implement the toString() method that will print out the shape name, any attributes (ex: sideLength), and the area.It also includes the Shape base class. You will need to add the 3 subclasses and add the appropriate code.
