<br/>
The error out of memory is on the line: gr.DrawImage(newImage, new Rectangle(0, 0, sourceImage.Width, sourceImage.Height));
And lets say in this case that each image file resolution is: Width 5184 and Height 3456 and i want the output to be resolution of 512x512

The out of memory full exception error message:
