I am "weeks new" to visual basic 2008 but I was hoping that someone might tell me how I can open an image in whatever type of "visible" graphics window (always positioned at: x=0 y=0); move to some "definable position" of interest x=(n) y=(n); change the brightness of that "individual pixel" by some "definable means of measure" from its original state; and save the new image as a separate image file?

View 30 RepliesI have the latest versions of VS 2010, .NET 4.0 and MVC 3 and I have a problem using areas in asp.net mvc 3 when using vb.net.
I do the following:
Create a new visual basic asp.net mvc 3 project. Select Razor as the "View Engin" and call the project "TestApp".
Create a new area called "Test", it will be in the folder: /Areas/Test.
Add a new empty controller called "PageController.vb" in /Areas/Test/Controllers/".
Add a new folder in /Areas/Test/Views/ called "Page".

These are identical with what you get if you repete steps 1-7 and use c# (only difference is that you will get c# code that is equal to above vb.net code).
I repete: If I do the steps 1-7 in C# it works, but it will not work in vb.net!

How to zoom a particular area of Image in vb.net
Like e.g.,(50,50,100,100)
how to zoom this small region of an image I Already know how to zoom an image but not how to zoom a particular portion
I'm working on a small project for the fun of it. One of my hobbies is astro-imaging and I take pictures of planets, nebulae gallaxies etc . One of the more challenging targets is the International Space Station. I have had some success with the ISS by manually aiming my telescope as the Station moves across the sky.
What I am trying to achieve is to write a program that will lock onto the brightest area of a webcam image. If the brightest area (which will be the ISS) is off center, then commands are sent to the telescope to recenter it.
So far I have been able to write code that talks with the scope, and I have been able to get a webcam stream to show on a Form.
So the last piece of the puzzle (well I am sure there will be other things that have to be worked out) is to identify the brightest area of the image. I am scratching my head as to how I should accomplish this.
I'm thinking I should dump pixel information into an array maybe, and establish which line and column has the brightest average values (I could then draw a cross hair over the image).
i am new to vb. i have created a program which has work areas/image areas. i can create as many as i like and i have created a code to delete a work area. but i cant delete more than one and i cant find out how to fix the problem i will post my code so you can see what i have out so far,

I am currently working on image cropping software. Any idea how to make image under rectangle to be clear and outside area translucent?
View 5 RepliesI'm working on a Vb.net project. I have a form with a RichTextBox or a simple TextBox control. It contains hundreds of text lines, so the control has to be scrolled.
I want to send to a printer only the lines that are currently seen on the control window.
That is, I want to convert what I see into an Image and then draw that image thru e.Graphics.DrawImage.
As you can see, it could also be the case of a ListBox, a TreeView or any other scrollable control.
How can I grab that rectangle area and then convert it into an Image? The rest I already know how to do it.
i have a program with the ability to save view and scan images. i am currently working on making work area's. so i have two list box's. listbox one is for the image area name. listbox2 is to list the pages in selected image area (mouse click). i have created the form to show you and i will post a link below. i have started trying to do it but have got stuck. i use an input box to give the image area's names. but thats as far as i have got at the min.
i need to be able to make image area's and list/view the images in my picturebox. plus i would like to create a folder or how ever many the user makes behind the scene thats called whatever the image area is called and in that folder is the images the user has saved in that folder. sorry if this is hard to understand. i have asked on another forum but i didnt get what i wanted it to do.

i have gave you a link so you can see what my form looks like so you have a slight understanding on what i want it to do. its work in progress so sorry if it looks rubbish.
by the way i can save an image but it only saves it one certaint place and i cant save more thasn one as it replaces the image. and as for the scanned image thats the same.

Basically the forum size is set to 600x2000 but the client should only allow you to view 600x600. I want it to add +1 once you "collide with a invisable box I'll add and this will redraw the screen.

It includes the upper Bar and lower frame. Is there an instruction to set the From's inner pixel size and not overal?

View 3 RepliesI'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,
