Trim Transparent Pixels not working in CC

I updated from CS (finally caved to a subscription) and I'm having trouble with some essentials. 

 

Image > Trim doesn't work in CC?  I use Trim like every day but in CC it doesnt seem to work anymore. I contacted 3 Adobe techs today and gave them remote access. They couldn't fix it.

 

The issue is that I have like 50 layers (example) in a file, and normally, I would go to Image > Trim - Transparent Pixels - and all the content that is not visible in the work area would simply trim away. I need to find a way to fix that, it's a necessity.

 

Related : Every time I draw a box or anything from edge to edge, it doesn't snap to the edges of the visible work area anymore, it goes beyond that into the gray area around the work area.  It should stop by itself at the edges but it doesn't. So now when I save Slices (yes, I prefer Legacy Export) I'm saving images that are too large, they include the content beyond the edges of the window, it's super annoying. Any way to fix that?

 

Last item : The window keeps scrolling past the edges of the work area. I end up scrolling way past the edges of the window, into the gray area, it isn't stopping at the edges anymore. I'm sure some people like this, but I prefer to only access this behavior in Full screen mode, not all the time (it's hard to work like that, with the window floating all over the place). I've tried to change the settings, but nothing seems to work. I've disabled Overscroll, but it's still over scrolling past the work area. 

 

Does anyone know how to fix these things? I actually can't even finish this one project because I can't get the Trim to work, so that's most important at the moment.

Thanks so much! 🙂

You have something in or outside that transparent artea which is blocking the Trim command.  Try grouping all of the layers and and using Cmd T to start Free Transform, and seee if the bounding box extends into or past the transparent area.  If it is outside, select Crop and turn on Delete Cropped pixels in the Options bar. Hit one of the corner handles to activate the crop, and OK it. That will remove anything outside the document bounds, but there might still be something inside.  A single pixel at 1% opacity will stop Trim working.  You just need to do some detective work to track down the errent content.

 

Let us know how you get on, because this could be an interesting situation.  Good luck.

I have TONS of stuff outside the document bounds - that's the idea of using Trim Transparent Pixels. That's what that tool usually does, it trims everything that is outside the document bounds. That's what I'm trying to use it for, as I've been doing for the last 25+ years. I did also try Crop - delete cropped pixels, but that didn't work either.  I selected the entire document, hit crop, and it didn't crop anything outside of the document bounds.

Did you try Free Transform? I have deliberately set up the situation I referred to below as an example.  I only had one layer and you mentioned having lots of layers, so that's where the detective work is.  If you try Free Transform and it shows no content beyond what you thought to be transparent, then we have a problem.  My guess is that won't be the case, but check it and see.

Not exactly clear on what you mean, but I selected a layer and turned on the Show Transform controls and it looks just like the image you posted - there's content beyond the boundary, in that dark gray area, that I can't see of course, but it's there with the transform points. So that's the stuff I'm trying to Trim on all layers. That's the whole problem right there.

If you select one layer at a time and hit Cmd T, any that show the extended bounding box have content beyond the document bounds. Trim will not work with Transparent selected when that is the case.  If you do what I described back up the thread you can delete that content, and Trim will then work.

 

Select all layers and group them (Cmd g)

Select the group and click on Crop.

Make sure Delete cropped pixels is ticked in the options bar.

You need to activate the crop for this to work, by clicking on one of the corner handles.

It will go from this:

To this indication the area being cropped

Do this and try Free Transform again (Cmd T) and you should see the boundery box no longer extends past the document boundary. 

Trim will now work when set to Transparent, but only if the is still no hidden content in what you take to be transparent.

"Trim will not work with Transparent selected when that is the case" - that was exactly how Trim used to work though, before CC. I never had to group layers and do all these extra steps to Trim the content outside the work area. It used to be one simple step - Image > Trim - Transparent Pixels. That did all of it at once. Seems Adobe really screwed up with CC, making it so much harder to achieve the very basics that were there before. I wish I could still use my old CS version, but I got a new computer and it doesn't work beyond OS Sierra. Removing basic functionality is so backwards.

 

Thanks anyway for trying to help, I do appreciate it.

Also tried Legacy Crop. 

 

nothing... I'm still able to drag layers around to reveal parts that were beyond the edge, so crop doesn't crop either.

 

Maybe it's all jacked up for Mac OS?

Jane, there are certainly known issues withg some Max OS versions, and hardware like the M1 processor, but I am a Windows user and not well up with that.  Tell us what OS version and hardware you are using, and we'll add that to the subject line to attract the best people to your thread.

I missed this the other day. I'm using OS 12.5. Everything is updated. And After so much back and forth with multiple Adobe tech people, they couldn't resolve it. One guy said he was going to work on it overnight and get back to me, but he never did.  It is super frustrating and held up my latest project several days, so a simple thing like not being able to Trim before saving slices, is a major issue.

 

Thanks everyone for trying to help 🙂
