posted below uploads and resizes a jpeg, probablem is, the outlook can look
a bit bitty becuase of teh samller size...is there a way I can anti alias /
smooth the resized image before saving?
If myThumb.Content Length > 0 Then
Dim myThumbData(myT humb.ContentLen gth) As Byte
myThumb.InputSt ream.Read(myThu mbData, 0, myThumb.Content Length)
Dim FileStream As New System.IO.FileS tream(strTempSa vePath &
"rawupload-thumb.jpg", IO.FileMode.Cre ate)
FileStream.Writ e(myThumbData, 0, myThumb.Content Length)
FileStream.Clos e()
' Create New image and bitmap objects. Load the image file and put into a
resized bitmap.
Dim g As System.Drawing. Image =
System.Drawing. Image.FromFile( strTempSavePath & "rawupload-thumb.jpg")
Dim thisFormat = g.RawFormat
Dim intThumbSize As New Size
intThumbSize = NewImageSize(g. Width, g.Height, 90, 90)
' Create bimap in memory to manipulate image.
Dim imgOutput As New Bitmap(g, intThumbSize.Wi dth, intThumbSize.He ight)
Response.Conten tType = "image/jpeg"
' Resize done, now save the file back to the temp directory.
imgOutput.Save( strTempSavePath & "upload-thumb.jpg", thisFormat)
' Tidy up the objects
g.Dispose()
imgOutput.Dispo se()
' Set URL for uploaded image to be previwed on page where this control is
included.
imgThumb.ImageU rl = "/catalogue/images/tmp/upload-thumb.jpg"

Is there a way I can anti-aliasing a gif to be able to get a
hi-quality resizeable backgroundpicture.
When a GIF of JPG is being resized by the browser you get wurse
pictures because it needs a anti-aliasing. Maybe there is some filter
for it...
Or can I write my own subroutine to do this in client-browsers?

I'm trying to use the capCreateCaptureWindow (see

I am creating a control that will take an image and make parts of it
transparent, this is done by creating and then applying a region to the
control. The control inherits from picturebox and works fine when loading
the image into the control, the problem that I am having now is, once the
control is loaded and the image is displayed, if the user resizes...

Howdy,
I have a function that uploads an image and that works great. I love ..Nets built in upload, so much easier than 3rd party uploaders!
Now I am making a public function that will take the path of the uploaded image, and resize it with the provided dimensions. My function is below. The current function is returning an error when run from the upload function: A generic error occurred in GDI+. Not sure what exactly that means. From what...

Hello.
I'm trying to create a simple program that amongst other things creates a
thumbnail of an image (Bitmap) to a set size determined by the user in
pixels?
The problem is: All of the examples I have seen so far are in c#.
Can anyone please provide reference to a c++ managed version.
Thanks.

Hello,
I've got this problem:
I loaded an icon (with alpha and smoothing) into a graphics object.
Now I want to display it. The best solution would be if I could convert
it
into an image object so the picture box can display it.
Does anybody have an idea how I could do that?

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:

For most users, this new feature is actually very convenient. If you want to control the update process,...
