Create Graphics On An Image In A Picture Box?
May 25, 2009
I am creating an application where when I click on an image I need to mark the place using the x and y co-ordinates given by the click and then after marking I put a red dot/circle on that spot and then I need to save this image to a file including the dot/circle I marked. I have tried saving the image to the file but to no avail, I have been able to only save the PictureBox image and that doesn't include the graphics. It is only the base image. I have tried to save it as a bitmap but have not gotten anywhere with that either. It seems whenever I call the image.save it takes only the value of the underlying image and saves it.
Private Sub BtnCreate_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles BtnCreate.Click
pointmarked = False

anyone know how to do this, but wit a browse for folder aspect..like i open up my browse for folder window, select the folder i want and it displays the .png file in picturebox..i'm trying to figure it out..here is what i have so far..i have it setup where i'm opening up a folder and loading certain files in my checkedboxlist..but i also want a .png file that is in the subfolders(the only .png file in the entire directory) to be displayed in the picturebox..but the folder is going to be changed depending on which folder is selected..so it can't be a set directory or path..basically has to change like the checkedboxlist.

I dipped my toe in the world of user controls as needed to double buffer a panel control and now want to create a picturebox control with a thicker border. Writing a dice based game, the dice represented by pictureboxes when clicked are highlighted and their border style changes FROM BorderStyle.none TO BorderStyle.FixedSingle, which is where I want to increase the thickness of the border. My user control code increases the border thickness using the code below:-

I am building a program which offers solutions to the travelling salesman problem (finding shortest tour between a set of cities while visiting each only once).
My program loads a bitmap image of a map into a picture box. From there, graphics which point out the cities as well as tour paths are drawn onto the map. My problem is that when the option to plot ALL cities is enacted, the user may choose to pinpoint a specific city with a separate control. When the user erases that pinpoint via an invalidation routine, though, it erases all graphics beneath it, which is undesirable. How can I make my tour graphics and city plots semi-permanent by drawing them directly on the image? I tried drawing them on a separate bitmap, but it 'covered up' the map image.

If I put my DrawObjects() sub into picturebox paint event.When ever a picturebox.refresh or picturebox.visible = true (vb.net seems to draw my DrawObjects() first, then load the jpeg Image over my drawing - erasing drawing) Is there a way to get the picturebox to redraw the jpg image first then draw on it, in picturebox paint event?

I am building a 2D game where the user is a circle(:P) and the enemies are rectangles coming at him. However, my problem is that when I placed a very nice picture of space I found on the internet, the screen draws whatever it has to underneath this image. Everything works,I can still see my lives going down when something collides into me - except the fact it is all covered up by this picture. How Do I Draw everything ON Top of this - (I tried using the 'Send To Back' Command)
EDIT: The form draws everything through a timer, and the user controls his character through keys.In the mybase.load procedure:
PicBackGround.Dock = DockStyle.Fill
PicBackGround is the picture box with the image.In the paint procedure:
e.Graphics.Clear(Color.Black)
e.Graphics.FillEllipse(Brushes.Orange, Player)
[code]....
Player is a rectangle declared right at the top, Dim Player As New Rectangle(0, 0, 50, 50); There is then the array Objects, which stores all the data about the enemies coming at the player, Current_Projectiles is simply an array to store data about rectangles(bullets) that the player fires.

I'm a VB beginner.I've been playing with Graphics.DrawString by watermarking a picture with a text string. The picture below to the left comes from PictureBox with a text string drawn with Graphics.DrawString. The font style used is Arial 48 points, regular, I think. The picture in PictureBox shows just as I configure. Great... The resolution of the original Terri Hatcher picture is 300 dpi (300 x 300). Exporting this picture with Graphics.DrawString, I get the picture below to the right. The text string appears a lot bigger than previously shown in PictureBox. It turns out that the text size varies, depending on the resolution of the original picture. That's kind of odd. I develop several graphics applications in a different environment and have never seen this sort of graphics.drawstring thing. Anyway,
my sample application seems to draw a text string at an image resolution of

I made a picture box and imported an image named Title.jpg. Later I made adjustments to the picture and imported it again without deleting the original(mistake). The new one had the name automatically changed to Title1.jpg. So I deleted the original image from resources and renamed Title1.jpg back to Title.jpg.
Now I got two problems. First, only Title.jpg is on the solution explorer, but Title1.jpg(along with Title.jpg) still pops up on the resource list when I click on Image property of the picture box. There's only the name and no picture, and I don't see a delete option. How do I get rid of it? Second, even though I changed the image to the new Title.jpg in the picture box, the old one is displayed when running the app. What's up with that?

So far, I have always run applications within the IDE, using Debug Mode.If I publish an application will I have to add code to repaint Picture Box graphics?In the IDE, my Picture Box graphics never get disturbed by running some other application or minimizing my forms.
I have noticed some discussions which suggest that code is needed in the Paint Event Handler in order to redraw graphics which disappear due to minimizing the form or running another application which displays a window covering my application.

I have managed to build the basic Picture Viewer Program. Now Remember the program I am working on is for a Digital Picture Frame there is NO wirless network adapter on the old pc and there is no keyboard going to be attached to the laptop so the program must launch its self (ill put a short Cut in the windows startup folder). I got a picture box that excepts the picture file it covers the whole form! (when there is a picture in the picturebox1 it fits the screen) My form one covers the entire screen (I set the windows border from scalable to none). I need to make my program scan for picture files on different drives and then every 30 seconds or so choose a random picture from the usb drive and display it Posted below is my code:
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
OpenFileDialog1.ShowDialog()
PictureBox1.ImageLocation = OpenFileDialog1.FileName ' want to remove this feature so the user cant see this

I am designing a program to be similar to Microsoft image viewer. I want it to open on PC start up Full screen and I want to make it scan for Images on flash drives with the user doing anything. I am making a Digital Picture frame out of my old dell laptop and I would like to make the program for it. How to have it play a random image every 30 seconds or so...

The problem is that i am trying to resize pictures so they fit into a picturebox with good quality. I have found a code (se attached code) on the internet that resize the picture correctly but the quality is poor.
If i resize the picture in Adobe photoshop before i put it into the picturebox the quality is good so there is nothing wrong with the orginal picture or the picturebox. It's the resizing that is the problem.
Here is the code.
'Generate new image dimensions
Public Function GenerateImageDimensions(ByVal currW As Integer, ByVal currH As Integer, ByVal destW As Integer, ByVal destH As Integer) As Size

I made a program that uses the graphics object to draw on a picture box. I used the graphics.fromhwnd(picbox) to draw on the control. The problem is if I minimize the window the drawing disapears. Might there be a way I can the image from the picbox and save it to a bitmap variable ?

When working with small images, the graphics interpolation does bad work.the result image in the following code does ignore second half of image to draw.Draw something on the image by using loadimage from JPG or whatever you want.
Dim GrayImage as system.drawing.Bitmap(640,480)
Dim bmTmp As New System.Drawing.Bitmap(GrayImage.Width, 1)
Using gr As System.Drawing.Graphics = System.Drawing.Graphics.FromImage(bmTmp)[code]....
The second half vertical is not drawn by using the DrawImage methode. I want to have the image as result as you see on first picture. Stretched image with source on whole content.
