Pastespec command distorting aspect ratio when importing images

[Anonymous]

In my job I often have to copy images from pdf into autocad, and draw over them. I need these images to be quite accurate. To do this I have been using the windows snipping tool, saving the image, opening in paint, selecting all, copying all, then using pastespec -> Picture(metafile) to add the picture to the autocad drawing. I do it this way as I want to embed the images, while keeping the resolution regardless of how it is zoomed in or out. 

I recently noticed that after doing this the images are sometimes slightly stretched, so that they have a different aspect ratio than the original image. I did some tests and realised it was the pastespec command doing this, since if I simply pastespec the same copy over and over, the resulting images will not all have the same aspect ratio. 

I am guessing this is just a bug/inaccuracy with pastespec and there is nothing I can do about it. 

Has anyone encountered this before? Is there another more accurate method I could use to import the pictures which keeps image quality even when zoomed out? If I try to paste in the images normally I get distortion like this:

I am using Autocad LT 2018.

Thanks in advance.

Hi @Anonymous,

Have you tried opening the PDF in Adobe Acrobat or something similar so you can export the image and then paste (or Underlay) into AutoCAD?  Doing so means you are working with the actual image data rather than a screen representation of it.

If you attach the PDF as an underlay does it seem to be accurate?
