title: Photoshop: Copy and paste an image without trimming transparency
body: <p>I have an image fo this kind:</p>
  
  <p>1000x1000 but only a portion of the image is opaque, think a filled circle on the left, other picels are transparent.</p>
  
  <p>I want to copy/paste only a portion of the image with an area choosed by me:</p>
  
  <p>I drag and drop the mouse so that part will be 400x100 but when i paste i have an image 300x76. 
  photoshop has trimmed my image, but i want it with the border of the image choosed by me, i want that coordinates.
  preparing an image 400x100 blank and copying that image doesn't solve my problem because i must pan the image on the original position.</p>
  
  <p>how can i copy/paste the image without trimming?
  thanks</p>
