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?

Interface And Graphics :: Initialize Graphic Dependent Data?

Sep 15, 2008

I am struggling with VB.NET's graphics paradigm.There are several times in my code when I need to determine the width of some text. Under VB6 I would use the .textwidth() method pretty much any time I wished.Under VB.NET it appears that the paint event is the only place I can gain access to an initialized graphics object and from that the measurestring() method.

Interface And Graphics :: Rotate A Graphic At A Specific Point?

Dec 9, 2010

I want to rotate a graphic at a point and I used the centerX and centerY to define the center of rotation.
Here is what I wrote:

Dim rotate_mirror as new RotateTransform(CSng(txtbx_rotate_by.text))
rotate_mirror.centerX = 5
rotate_mirror.centery = 55
blk_mirror.RenderTransform = rotate_mirror

blk_mirror is the graphic I want to rotate. Unfortunately, It does not work.

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


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


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


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 _                       
' 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?

Declare Graphic Ellipses As Group?

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...
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.

VS 2010 Graphic Equaliser Display?

I have started to create a player using VB.NET. Ive completed the import music functions and creating playlists and importing the playlists But now im wondering how would i go about creating a Graphics Equalizer to display the songs playing I dont mean a Equaliser with controls and such but more a visual display of the song playing much like the visualisations within Windows Media Player.

Also if i wanted to display a visualisation behind some controls , What would i use to achieve this ?? I think a picturebox if it accepts the type of file a Visualisation would be. My final goal is create a fully custom player which has a visualisation and shows track details in a custom environment.

Combining Images Into A Single Graphic Object?

Jul 24, 2010

I am attempting to combine multiple bitmap images into a single graphic object using Drawing.Drawing2D command but am noticing the image quality changes.I tried various combination of these ...

g.InterpolationMode = Drawing2D.InterpolationMode.HighQualityBicubic
g.SmoothingMode = Drawing2D.SmoothingMode.HighQuality
g.PixelOffsetMode = Drawing2D.PixelOffsetMode.HighQuality
g.CompositingQuality = Drawing2D.CompositingQuality.HighQuality

but did not get the "perfect" quality.What I want is one image to be in one region of the graphic object. Another image to be in another region. There is no overlapping of the image regions so essentially I want an source image to be as is in a given region. I noticed an option for "CombineMode" for Drawing2D but cannot figure out if and how to use this to get what I want.
