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.)

Oct 5, 2005I'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

Resize A Rotated Shape?
Jan 25, 2010i'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.

View 10 RepliesInterface And Graphics :: Line Gets Smaller While Being Rotated?
Dec 17, 2010I'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 :
Quote:
HTML Code:
Dim theta As Single
Private Cntr_X_blu_Mirror As Single = 5
[Code].....
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!
Transparent Rotated Image Shows Original
Aug 15, 2010I 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 {:<(

VS 2005 - HitTest Rotated Rectangle With Four Points?
Jul 20, 2010I'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?
View 9 RepliesC# - Enable Me To Render Rotated Text With The TextRenderer.DrawText Method?
Oct 6, 2010I'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.

Asp.net - Controls (buttons) Be Set In A ModalPopup Extender Panel That Do Not Close The Panel?
Apr 21, 2009When a user is editing a given piece of data, they're allowed to add messages/comments. These are stored as child records in a SQL database. Clicking on the Add Message button brings up a panel (pnlMessage) courtesy of the AJAX ModalPopup Extender. This takes some input and, when the "Send Message" button in the panel is clicked (I learned the hard way to NOT make that the 'OkButton' property), the message is stored in the database and an email is sent to the intended recipients. No problem there.
However, I need to be able to allow the user to add new email addresses (so long as they are registered in our database). I have another ModalPopup / panel combo (pnlSearch) that's tied to a button on the previous panel (pnlMessage).
The user is supposed to be able to add an email or click on a search button to populate a list to choose from.
The pop-up panel (pnlSearch) comes up just fine, but clicking the "Lookup" button (which instigates the search and returns a collection of records that the user is supposed to pick from) closes the panel.
Previously, I ran into the problem of having the Button.Click event never firing when I put the Button into the "OkControlID" property (the CancelControlID works fine since I don't want to do anything). Removing the "OkControlID=Button" line allowed it to work perfectly with the Button.Click event firing as expected.
So now I have the Search panel with a button for "OK" and a button for "Search" - but the panel should stay up and visible after the Search.Click does it's thing. Am I missing some property that basically says "don't close the panel when this button is clicked"? Of course, if I bring up the panel again in the same session, the results from the previous effort are there (the search results).

[VB2005] Rotateflip Image Is Eating More Memory Than Non Rotated Image ?
Sep 8, 2009 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
Autoscroll X.panel According To T.panel's Scroll Position
Mar 19, 2009This is for a mapping/plotting program.
t.panel is the main panel and it has too much content to fit in one screen so there are scroll bars. x.panel contains the horizontal scale for the data points in t.panel. I drew the scale using a bitmap and set it as x.panel's background.
Setting x.panel's horizontalscroll.value = t.panel's horizontalscroll.maximum doesn't seem to work. I think this is because x.panel's doesn't have any content that causes it to need scroll bars.

View 3 RepliesVS 2008 Scrolling In A Panel?
Mar 4, 2010I have a panel on my main form that has vertical scrollbars enabled. I also have a custom control I have built that is the same width as the panel and has a height of 45. I store multiple of my user controls in an array, and I want the panel to display these controls like a listbox... one stacked on top of the other. So I loop through the array and add each control to the panel at coordinates right under the previous one.This works fine, and as long as I use the the mouse to scroll down and expose the controls I'm interested in and then clicking on that control, things work great. The problem comes in when I want to use the arrow key to move down to the next control. If the next control is visible on the panel, it works fine.

[2008] Transparent Image On Panel?
Jan 14, 2009I have a forms app that contains a panel. This panel contains an picturebox - the user can then drag the picturebox image.
I need to add an image? in the panel that will not move when the user drags the picturebox image.

I've tried drawing directly on to the panel but nothing appears. Perhaps what I am drawing is behind the picturebox?
