Pre-flight check non-proportional scaling

[minimejdh1]

I have attached a book cover file that I created in Aff Pub v1 to export to PDF for publishing by a 3rd party company, Blurb.  The content is a separate document.  In pre-flight, I first got a message warning about not extending to bleed.  When I made sure the rectangle on the back and the larger photo on the front were extended to the bleed, I then got a message about non-proportional scaling.  

A couple of questions:  1)  How do you know which image is being referred to?; 2) I tried to follow the instructions to double-click on a handle of the large-sunset picture. But nothing changed.  I am not sure if I did it right.  Not sure how to fix this.  

Thanks.

I figured out how to do the double-click thing.  On another page, I had put a Stock pixabay image as a background on the right page of the spread.  It gave me the same non-proportional scaling. When I corrected that it brought the image way over on to the left page of the spread and it did not extend to the bleed. So I had to correct that.  What is the issue with non-proportional scaling?

Hi @minimejdh1,

The Preflight warning indicates that your images has been scaled non-proportionately on your canvas in relation to it's vertical and horizontal scale. For example, if you only decrease the vertical scale of an image to squash it that would be scaling it non-proportionately compared to it's original scale/aspect ratio. Double clicking the handles or setting the image back to 'original size' along the context toolbar will correct this.

It's worth noting that this is merely a warning, and can be completely ignored if the current image scaling was intentional. You can also opt to turn this warning off or adjust the pixel threshold that the error kicks in in the Preflight Profile editor.

Thank you @NathanC  I also figured out that depending on which side you shift-double-click to make it proportional it can extend beyond the printable page or frame.  It helps to know if it is the way I want it to be then not to sweat it.  I also figured out how to know which picture was identified.  Still learning...
