+Sometimes, it is necessary to crop an image before inserting it into a PDF. Use can use `AddImage()` method to support adding cropped images:

 ## Place image on page and preserve (control) aspect ratio
 
 If we do not know the dimensions of the image there is every chance of getting a distorted image on the page. The following example shows one of the ways to avoid this.
