Create Image From Graphic?

Feb 18, 2010

I am programming a design surface where I add Image objects to the surface when an image is added it calls the draw objects command. It works fine I would like to figure out how to covert the object to an image to save it? Below is the draw sub used to draw objects onto the surface:

Public Sub DrawObjects(ByVal g As Graphics, ByVal Scale As Single)
Dim drawObj As GraphicObject
Dim i As Integer

Create An Event Handler For A Graphic Elipse?

Dec 25, 2009

I'm trying to create an event handler for a graphic elipse, so I can do the math in a separate "control box". There will be multiple graphic elipses feeding the TextBoxE1 box. ( As for all the note textboxes.) This is a graphic creation of a guitar neck that will tie to a 2 table database. Click on a note & it will be identified, a series of notes will call on the related scales from the database. The problem is that I need to create an event handler for each graphic elipse so the code won't fire unless the elipse is clicked on. If only one elipse in that keynote value is clicked, it will put a "1" in TextBoxE3. TextBoxE1 & TextBoxE2 will be hidden.

TextBoxE1 value = "0" until at least one "E" is clicked. ( Elipse that is valued as "E".)
TextBoxE2 value = "1"
TextBoxE3 value = TextBoxE1 + TextBoxE2

Create Graphic From HDC Results In Arithmetic Operation Overflow

May 12, 2012

I attempt to prepare printing document by using WinAPI instead of (System.Drawing.Printing.PrintDocument) because Graphic.DrawString does not render Khmer Unicode properly. Only TextRendering.DrawText renders it properly. I believe Graphic is GDI+ wrapper and TextRendering.DrawText is using GDI. Furthermore, PrintDocument does not work with TextRendering.DrawText.

Interface And Graphics :: XNA Graphic With A Graphic?

Jan 14, 2010

I'm trying to make a mini map for a 2d space shooter of mine; I've for the math down (I think) for when an item should appear on the mini map, but the problem is the graphic. As it stands, the graphic spills over the edge of the mini map graphic and disappears only when it's fully outside. I need it to crop the image, or at least not show it off the mini map graphic.I thought of using the sourcerect rectangle of the spritebatch.draw, but it seems to me that would only work for the right and bottom section, as I can adjust the size of the rectangle. I haven't tried this yet, but I will soon. Can the location of the source rectangle be changed in relation to the graphic that it is a part of being drawn so that I can use that to crop the left and top sides?

Declaring A Graphic In VB?

Apr 13, 2010

We have a great book written for Visual Basic 2005 that we type code that is prepared in advance. We are using Visual Basic Express 2008 and normally this works really great; type the code run the program and it works, however I am running into a snag.

The textbook shows the following code: IN THE(General) (Declarations)AREA we are told to type the following:

' Create a Graphic object to use with the game's bitmap
Dim myGraphicObject As Graphics = Me.CreateGraphics
' Create an empty Bitmap Object

[Code].....

is there a difference between VB 2005 and VB 2008 that would be causing the errors? or am I missing something subtle maybe mistyped?

Creating A Graphic Barrier?

Feb 17, 2011

I am working with a graphics program in VB to move an image around the Form. I'm trying to create barriers that cannot be crossed. At first, I tried to represent this with a 2D array, but this proved too complicated. For now, I'm trying to create a series of rectangles. What I want to happen is when the point the image is anchored at intercepts one of these rectangles, it will either be prevented from moving or sent back to where it was directly before the image moved. I know there is an intercept command, but I've been unable to figure out how to use it in this content. The code I have is below.

Public Class Form1
Dim PlayerSprite As Image
Dim BGImage As Image

[code]....

As I said, this is to create a graphic barrier. However, I expect to make a number of these Rectangles?

Load A Picturebox Using Graphic From Web?

Jun 1, 2011

how do I set up a timer to load a graphic from the web to a picturebox

heres a sample graphic

[URL]

its real small so it will load fast. the link will be different but this is good enough to test with

I need it to be on a timer event to load this graphic every .... seconds, that part of the code I can do, timer events are easy. getting this graphic into a picturebox is a pain though.

Make Graphic Persistent In VB And GDI+?

Sep 24, 2010

I have a converted VB6 App that would draw irregular shapes on a PictureBox when I click on a button, and these irregular shapes would persist until I either close the App or erased the PictureBox to start the display anew.I converted my App to VB.Net to do the same, i.e. draw on a PictureBox again, but the drawn lines appear briefly and then, at the end of the drawing process, when my App returns control to the Operating System in wait for another event, the graphics disappear as if erased by the App (which I don't do of course).I have created a Graphics Object associated to my Picture Box as:

Dim CurrGraphics as System.Drawing.Graphics
CurrGraphics = PictureOut.CreateGraphics

I then use the DrawPolygon and DrawLine methods to add the irregular shapes I want:

CurrGraphics.DrawPolygon(CurrPen, Pts)
CurrGraphics.DrawLine(CurrPen, Pts(I).X, Pts(I).Y, Pts(I+1).X, Pts(I+1).Y)

where CurrPen is a defined Pen, and Pts is the Points() array with the coordinates of the displayed shape. Several dozens irregular shapes are drawn and then the subroutine stops, and returns to waiting for another request from the user.What could be the prime reason why graphics do not persist in a PictureBox, and are erased immediately after they are created ?

PS: I do not use the PainEvent of the PictureBox PictureOut, as in the example given in the VB documentation (below), as the display process is initiated by clicking on a button, and I cannot relate how to transfer control to the PaintEvent as below:

Private Sub Form1_Paint(sender As Object, pe As PaintEventArgs) Handles _
MyBase.Paint
' Declares the Graphics object and sets it to the Graphics object

Calculate Angle Into A Visual Graphic?

Oct 28, 2011

Ok. So I have a program I have made to calculate angles. i have a line for true vertical and I need the program to draw the line at a given angle. Basically, if I put 82 in textbox1, I want the program to calculate the cordinates where that line sits on the X axis, The y axis is always picturebox1.height, So the y axis isn't important here, just the x axis.

What would I do to calculate this angle into a visual graphic?

Very similar to the buttons you see in Excel/Power Point/Word 2007 at the bottom right of the screen. The buttons are next to the slider bar which increaes the view % of the screen. These buttons are grouped together and have different combinations of squares/rectangles on them for viewing options Any idea where to start with the shapes?

Declare Graphic Ellipses As Group?

Sep 7, 2009

I need to be able to declare 12 groups of ellipses as "group A" , "groupA#", "groupB", ect. That way I can fire all the images simultaniously from outside of the paint event handler.(if possible) I have tried several ways to declare them, but the system doesn't read things the way I trying to do them. This is my first time ever with graphic activity, so I don't have anything to fall back on. I went to the Bob Powell GDI+ site, but didn't find what I was looking for. Tried google too, but don't think I'm wording things right. Thays typically always my problem, noone understands me, 'cause I lack good communication skills. Heres what I have...

Graphic Visualizer For System Audio

Feb 19, 2010

I'm working on a side project which, put simply, allows for the playing of audio files of multiple types through the form or system (My.Computer.Audio.[...]). I need to grab the audio levels of sound currently playing on the system -- not necessarily what's just playing through my form.

A "full-audio graphic visualizer" if you will. However I just need a method of grabbing the data in the first place - the rest I have taken care of. The different values you see in a graphic equalizer are what I need to grab.

If you had music playing via Songbird, and started playing a podcast voice MP3 in Windows Media Player, I want to have it all-inclusive. I've looked in the My.Computer.Audio namespace, looked into Fast Fourier Transforms (which turned out to seem much more adequate for equalizers as opposed to visualizers), and more.

How To Declare Groups Of Graphic Ellipses

Sep 7, 2009

I have a group of graphic ellipses that I need to arrange in a group. 12 groups actually. It's a matrix for traing guitar students. I have the locations of the "G" notes grouped so far, but not under the title "G notes group". Since I can't use ellipses outside of the paint event handler, I have to rename them, I guess in the event handler...

Here's what I have so far...
Dim
GroupG As e.Graphics.FillEllipse(Brushes.Green, 84, 6, 10, 10) And
e.Graphics.FillEllipse(Brushes.Green, 84, 106, 10, 10)
e.Graphics.FillEllipse(Brushes.Green, 24, 46, 10, 10)
e.Graphics.FillEllipse(Brushes.Green, 124, 66, 10, 10)
[Code] .....

The paint event handler does not accept my attempts to declare them as a group, & this is my first ever project with graphics in an active state. I haven't found any where to turn for info, tried Google, tried bob Powell's GDI+ site, Tried some free ebooks, nowhere I have looked seem to cover this aspect. I need some direction to turn.
