Picture Aspect Ratio on load picture (Not resize)

[Mahmood Khaleel Pira]

Hi dear friends, I have a Picture previewer and I want to preview pictures in the ratio fit to the PictureBox, I used (Image1) to stretch the pictures but it is not cool for all pictures they lose the aspect ratio, How can I make it? How to make pictures fit to the PictureBox?
*******************
Picture below:
No.1: is a (Picture1) PictureBox, has not stretch!
No.2 is an (Image1) ImageBox, and stretched!



Please show me a way to solve this problem!
