Interface And Graphics :: Calling The Paint Event?

Mar 22, 2012

This is a working example which draws a rectangle on different location every timer_tick and I fully understand now how it's working:

Code:
Dim i, timercount As Integer
Private Sub PictureBox1_Paint(ByVal sender As Object, ByVal e As System.Windows.Forms.PaintEventArgs) Handles PictureBox1.Paint

[code]....

Now I'm looking for a way to draw this rectangles without refreshing them every single tick. I've just started using Visual Basic and I really don't know how to call/raise PictureBox1_Paint event every timer_tick or how to store drawing data in member variables?

Interface And Graphics :: Rotate A Jpg Image?

May 28, 2009

I have an application that downloads a .jpg snapshot from an IP camera, writes it to the server hard drive, attaches it to an email and sends it out to my users. Pretty simple until one guy had to mount his camera upside down and that's how he received the image via email.

It gets a bit annoying after a while, so he asked me if I could rotate it 180 degrees before attaching it to the email. I have absolutely no idea - hence my post. The app is on a hosted ASP.Net v3.5 web server.

Interface And Graphics :: Image Has Been Loaded Into The Picturebox1?

Sep 23, 2008

I am trying to verify that an image has been loaded into the picturebox1. I am loading the image from the web and need to verify it has arrived before I can save it to disk. If I save it to soon I will save nothing and that will crash the app. I have tried to use 'if PictureBox1.image = nothing then' ... 'End If', but that isn't a valid check. I can obviously not check picturebox1.image if it is empty or has an image.

So the question is, how do I verify that the file has finished loading?

Interface And Graphics :: Make A Thumbnail From An Image?

Jul 11, 2004

I am trying to incorporate in my vbdotnet application a form in which I would like to make a thumbnail from an image. So what I have is two picture boxes, one with the source image and the other with the destination image, I would like to crop the image from picture box 1 and display it on picture box 2, but the way I wan to crop it is not giving the coordinates of the selected area box but to simulate a selection area box in which the mouse can move the box and select the area of the picture to be cropped. This selection area box would give me the coordinates i need in order to proceed the cropping. The problem is I don't know how to create this selection area box. It is like doing the cropping on a graphic design software like Macromedia Fireworks, Adobe photoshop, even paint.

Interface And Graphics Image Pixel Viewer

May 3, 2011

I would like to create a pixel viwer (i.e. zoom into a picture to view the image's pixel information - Similar to windows paint or Photoshop). I have created an image zooming code, but it enlarges the image and sadly, doesn't show the blocks of pixels I was hoping for.I have thought of several ideas, but each worse than the next. As an example, re-create the image, increasing each pixel's area based on the zoom-level. But I can tell already that this process would be slow and judging by photoshop (or paint) there is a quicker method.
