VS 2010 Clipping An Image?
Jan 28, 2011
I have a picturebox with a nice rectangular image. Actually, there are a series of images that are animated using a timer. The series of images are built dynamically in a single routine. Some of the actual shapes that are being drawn are rectangular, which is really convenient. However, there are some other shapes, and those are not working so well. I have no experience with clipping regions, so I'm not sure even where to look. The code I am using for drawing a circular region is this:
[Code]...
The intention of that code is that dSurface is the current animation frame (this is run in a loop). I then created a graphicsPath object, added a circle of the proper size to it, set the clipping region based on that GraphicsPath object, then drew a further circle on the picturebox. That last circle draws correctly, but the image isn't clipped in any way.
I'm not sure that I am doing this part of it right. I would assume that the clipping would mean that the image is drawn only within the circle designated by the GraphicsPath, with nothing drawn outside of that circle, thereby making the PictureBox (which is mPB in that code) appear circular.

I've drawing text to a rectangle, say for example "ABCDEFGHIJKLMNOPQRSTUVWXYZ123456789",That should be centered (which it is), but be on one line, not clipped like this:
"ABCDEFGHIJKLMNOPQR
STUVWXYZ123456789"
my String Format is:
With sfFormat
.Alignment = StringAlignment.Center
.LineAlignment = StringAlignment.Center
.Trimming = StringTrimming.Character
.FormatFlags = StringFormatFlags.NoClip
End With
It doesn't even have to trim it, like I have in my code, but it won't even stay on one line.

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?

I am trying to make an Image wrapper class or something. The reason for this is that I need to output a bunch of images only, without pictureboxes. I don't want an imagelist, because I need the images along with their associated image properties which an imagelist cannot provide. I ended up with this :

I have a specific image that I want my application to look for on a specific window. I've done something similar to this along time ago with VB6, but it was slow, and it was checking for specific points in the picture rather than the whole image itself (for speed reasons). I named this image "Image1.jpg" and I want to compare it to the window with the handle "001C08F2" and class "SunAwtCanvas"

I'm storing images in a List Of Image. When I want to clear/remove all the images it contains should I dispose & set each item to nothing before using .Clear? Or can you just call .Clear? I'm doing it like this for now...
' remove all images in list of image named "images".
For i As Integer = 0 to images.Count - 1
images(i).Dispose()
images(i) = Nothing
Next
images.Clear()

I have a list of points X(horizontal), Y(vertical), and Z(depth). I want to be able to plot them out so they can be viewed and since it is 3d I want to be able to rotate the image as well. There would be a line connecting each point to the next, until the end of my list. If possible I would also like to be able to click on an individual point on the image and be able to tell where that point is in my list.The problem is I don't have any idea on where to start on this. I know how to create some pretty basic/genaric 2d bitmaps but 3d and some of the features are an entire different story.

I am using the code below to download an image from the web. (Please don't say there are easier ways, i know that but i want to use this way) The problem is, is that i think the script is going trough all the 1000000 bytes defined. If i use less than this, the image sometimes comes out half done (like the bottom is gray) and if i use more i get a memory exception. Is there a way to use precisely enough? (So just as much as the image is?)
Function FetchURL(ByVal SomeURL As String, ByVal Referer As String, ByVal downloadto As String) As String

I have a form where i load an image to a picturebox. I open a dialog to prompt the user to grab a file and once that is done i pull the image into a picturebox. Now i want to resize all incoming images but.... because of how it affects my ability to draw lines in the picturebox i am restricted to leaving the picturebox size mode set to normal. So i set out to write a resizing function.
The issue i am having is that eventhough i pass the function an image. I get the Height and with from the image object and it appears that i should be tripping some of my IF/Then statements ... neither Scl or Scl2 ever gets set which in turn keeps nw_height and nw_width from setting themselves properly.
All 4 of those variables stay 0 at all times and im not sure why.

I'm trying to split an image into 9 smaller images; the code I wrote works fine for an image with dimensions that are evenly divisible by 3 (i.e. 150x150), but seems to cut stuff off for images with dimensions that are not evenly divisible by 3 (i.e. 800x800). While some distortion is understandable, the result I got looks way to bad to simply be bad resizing/cropping/etc.

I have picturebox that the user can import an image, and then save it to the datatable. I can save it with no problem, and the image, which is a logo, will populate onto my crystal reports pages.My issue, is that I want the logo to automatically load into the picturebox when the user opens my settings form. How can I do the opposite of the following:
'set the company datatable for sub
Dim borrowersrow As PlannerFilesDataSet.CompanytableRow
'use only the first row
