Question

Transparent Pixels Along Edge when Cropping to Full Width or Height

Hello,

 

When cropping images to the full height or width of the image (or crop along any side of the original canvas), then a 1px semi-transparent edge appears. For dark images, this causes a light strip when flattening/saving as a new JPG.

 

For example, if I crop the image like this, going all the way to the left and right edges of the image:

 

Then a transparent strip appears along the left & right sides:

 

When flattened to save as a new JPG, it's still visible:

 

This doesn't happen if I check "Delete Cropped Pixels", but then I can't finesse placement after cropping. It also doesn't happen if I bring the crop handles in a few pixels from the edge, but it's very tedious to do that for the high volume I work with, it's much more efficient to let it snap to the full width/height of the canvas. I tried adding a black fill layer below, which helps a little, but there's still a visible line. 

 

Is there any other way to avoid this?

    Hi @Elise_Claire, thanks so much for reaching out!
    I tried reproducing this on my end but haven’t had any luck. Could you let us know which version of Photoshop you’re using and, if possible, share a quick screen recording of the issue? That would really help us understand what’s going on.
    Thanks a lot!

    Hi @Aleke ,

     

    Sure! I've attached a screen recording, as well as the image file I used in the recording (I can provide additional image examples if needed). I'm using Photoshop 27.0.0 in the screen recording, but I've had this issue for a while and can also recreate it in version 26.10.0.

     

    I think I just figured out a clue, though - in my recording, I was cropping to 2048x1024px. But if I crop to a 2:1 Ratio instead, there is no transparency. But I always use W x H x Resolution because I need to crop to specific pixel dimensions for my work.

     

    Thank you in advance for your help!

    Is there any resampling at any point in this? If not, is it still visible when you view at 100% ?

     

    This happens when you have a floating layer (as opposed to a flat background layer), and the edge pixels are interpolated. With a floating layer, there are invisible transparent pixels outside the canvas, and they are factored into the interpolation.

     

    In a flat background layer (Background in the panel, in italics) pixels outside the canvas boundary are not allowed.
