how to save resized image in windows applications?
Oct 13 2010 8:54 AM
hi,
i developing one windows application in that application i load the image into picturebox and after that i resize the image image and next save the resized image.
i write a code for resize image is
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim image As Image = New Bitmap(ofd_Image.FileName)
Dim [Delegate] As New Image.GetThumbnailImageAbort(AddressOf ThumbnailCallback)
pb_image.Image = image.GetThumbnailImage(200, 150, [Delegate], IntPtr.Zero)
End Sub
Private Function ThumbnailCallback() As Boolean
Return False
End Function
and i write a code for save image is:
Dim fs As FileStream
Dim br As BinaryReader
Dim bw As BinaryWriter
Dim photo() As Byte
Dim save_ThumbimgPath As String = "D:\test.jpg"
fs = New FileStream(pb_image.ImageLocation, FileMode.Open, FileAccess.Read)
br = New BinaryReader(fs)
ReDim photo(fs.Length)
photo = br.ReadBytes(fs.Length)
br.Close()
fs = New FileStream(save_ThumbimgPath, FileMode.Create, FileAccess.Write)
bw = New BinaryWriter(fs)
bw.Write(photo)
fs.Close()
bw.Close()
MessageBox.Show("image saved successfully")
my problem is how to link with these 2 block of code. means
pb_image.ImageLocation is take original image location, so it save the original image dimensions. not to save 200 X 150 dimensions of image.
Please give me a solution
Thanks.
