For the resize I have a form to reduce and expend image code:
Dim source As New Bitmap(Form1.PictureBox1.Image)
Dim target As New Bitmap(Size.Width, Size.Height, PixelFormat.Format32bppRgb)
Using graphics As Graphics = graphics.FromImage(target)
graphics.DrawImage(source, New Size(16, 16))
End Using
As far as I know it resizes but when I save I get the default icon image instead of whats in the picture box?
In many apps I have needed to disable the maximize and resize features of the main window because the textboxes and buttons stay exactly the same without realigning or resizing automatically. How can I change it so that buttons maintain their proportions and that textboxes will stretch when the window is resized?

View 1 RepliesI'm making a tileset creator and everything is working fine so far except previewing a tile. The way it works now is it gets the image from a picturebox and calls the following code when scrolling the mousewheel. It functions fine but there is a border appearing between the tiles and I can't figure out why. The source image is 32x32 in size. Most likely it is the graphics class not measuring in pixels or something.

When I leave the scroll bar the imagelist repopulates from the files list. This can be very slow when working with high resolution pictures. I don't want to limit the image size to 2 sizes by using large and small imagelist.

View 2 Replieshow to resize images?
View 6 RepliesI would like for a user to upload an image to a file in my web application. However, before being saved I want to resize the image to a specified size. I have found code on the Internet to do what I want but I am having trouble adapting to meet my needs. Here is the part I am having trouble with:
' Resize Image Before Uploading to DataBase
Dim imageToBeResized As System.Drawing.Image = System.Drawing.Image.FromStream(FileUpload1.PostedFile.InputStream)
[Code]....
Rather than upload to a database I want to save the image to a folder in my web application. The problem I have encountered is that VB won't let me save a byte() to a folder. Not sure what I can safely change to adapt for my purposes. Why does it need to be changed to a byte() in the first place?
I have an app that displays images (using picturebox component). what I am trying to do now is to try to allow the user to resize the image how he wants it (scale). for this i think I need to create an instanece (bmp) clone of the selected image in the picturebox and draw it ontop of the original picture; then specifi new set of size points.I was trying to use the code below:
Graphics.FromImage(PictureBox1.Image).BeginContainer('i do not know what to do here')
I need to specifi the new size of the graphics container but I do not seem to have any clue on how to do it.
