I am aware of 'Stretch'. Much better to use Mode than stretch.

What I am doing gets a picture to line up with a GridView when being dragged. Below you can see it works. This allows me to resize the form and the image still lines up, so it needs to be exact. So sorry, 'Stretch' doesn't cut it!

Does this "stretch" work for you?  It seems to do what your shell command intends.  (I just noticed PJBlack's second line, so here is an example.)

Ced

Code (gambas)

  1. '=============================================================================
  2. Public Sub Main()
  3.  
  4.         Dim P As Image = Image.Load("~/Pictures/Wallpaper1920/DogOnDock.JPG")
  5.        
  6.         Dim I As Image = P.Stretch(200, 200)
  7.  
  8.         I.Save("DoD.jpg")      
  9.  
  11. '=============================================================================
  12.  
.... and carry a big stick!

Opps, sorry PJBlack. You were right, as is everybody else as well. It works like a charm.

Reminder, I must read posts more carefully! :?
