There are some fundemental concepts I am missing about graphics in VB.NET.
I have a control with an image that I want to rotate 15 degrees.
How do you get the contents of a graphic object into a image object?[code]....
how to rotate an image inside a picture box. Saw many for VB6 etc, but when tried it in vb 2008 nothing worked and got lots of weird errors.My project is to read a compass (electronic) send to the PC then create a nice compass image to rotate accordingly. All the rest of my stuff works, GPS reading and parsing etc..But cannot for the life of me, get that image to rotate.
View 17 RepliesI have made a program that has an image moving across the screen. The image changes its movement direction when the arrows are pressed. Now, I am trying to rotate the image (an arrow) to match the direction. Here is the subroutine to rotate the image. It uses the hidden PictureBox2's image (the original right arrow) as the source, because I couldn't think of any other way.

View 2 RepliesIm looking for an image viewer that supports most types of image formats, including PDFs, and has the ability to rotate/zoom, and draw on an image. I've been looking but to no avail. Does anyone have any suggestions on the best way of going about modifying a control so that I would have these features? The main problem that I am running into is the lack of the ability to draw on an image. Im still sort of a newbie to .NET,

View 6 RepliesI've rotate pictures using code like this vb.net Picture.Image.RotateFlip(RotateFlipType.Rotate90FlipNone)
How can I remove any rotation? I have a code which rotates images but and saves the roation to a database.For example I save a value such as
1 = 90
2 = 180
3= 270
4 = 0 (no roation)
Now looking at the MSDN on this topic if I wanted a user to rotate the image by clicking a button i could rotate 90 or 180 or 270. However, If I load the image location and rotation from a DB and the rotation is "2" I want it to roate 180. But using the same code If a user clicks a button (which goes through the options 1-4) and they are on "1" then click it and it goes to 2 i would only want to roate another 90. As at one it's already moved 90 so another 180 would mean it's rotated 270 in total.
For this reason I can not load a image and move it 180, I thought okay if I'm at "1" going to "2" I'll move it back 90 then forward 180 but if a image loads at 4 what does it do? does it go back thinking it's come from 3 or load at 4?
Following on from my question here [URL]
If I replace an image in a picture box, should I dispose the original image first?
Or, what about this situation:
Dim bm As New Bitmap(32,32)
bm = New Bitmap(32,32)
bm = New Bitmap(32,32)
bm = New Bitmap(32,32)
Does bm need only to be disposed at the end, or should it be disposed before each re-creation?
A big oversight there on my part. I knew a control took care of disposing its children but It hadn't occurred to me that I should dispose an old image if I replaced it.
How can I change the content of the PictureBox control based on user entry? I'm assuming it would be similar to this:

View 12 RepliesWhat line of code would I have to use in order to insert image into a PictureBox control?
View 2 RepliesI am writing a VB 2008 Express Edition application which has multiple forms. All of the forms contain one or more PictureBox controls. All PictureBox controls have assigned bitmaps via Image property during development mode. So far, all the bitmaps displayed during runtime without a slightest problem. Now, suddenly, not a single new one (i.e. which I add from this moment on) would display bitmap during runtime. All the old ones (i.e. those which I have added up to that unspecified point in time when something went wrong) still display bitmaps fine as they did before. But any newly added PictureBox (or, come to that, any other control which can display bitmap.
I have tried also Label control) displays the bitmap loaded via Image property only during development mode. During runtime the PictureBox shows as empty. I tried to load the bitmap during runtime via command Image.FromFile and that works fine (but I don't want to use this approach in my program). If I create a completely new application, all PictureBox controls display the bitmaps just fine. I don't get any errors or warnings in VB editor. I reinstalled the whole VB 2008 Express Edition including SP1 and .NET 3.5 SP1 with no difference whatsoever (as would be expected as any new application works with PictureBox controls fine).
I'm creating a program in visual basic 2008 that can scan an image straight to a picturebox using a scanner.
