Noob question about transparent pixels and bounding box


When I import a PNG file that has transparent pixels originally, Acorn seems to automatically trim it out. Is there a way to keep the transparent pixels when importing the PNG image? What I want is something similar to what Pixlr does when importing the PNG image. I hope I do not sound unclear. Thank you in advance for your help!

If you open the PNG in a new window then you can select all > copy, and then when you paste into your working document it will retain the selection including transparent pixels.

I did exactly that, but the problem persists. The transparent pixels get automatically trimmed when I paste it into my working document. Thank you for the reply.

I wonder if it’s the app you’re pasting into that is removing the transparent pixels?

I just tried it out on my end, and using select-all, then moving to Preview and using “New from Clipboard” will make an image with the correct pixels.

Yes, I want it to be pasted into Acorn without Acorn removing the transparent pixels. Is that possible in the first place? Thank you.

In that case it’s the place/website you are copying from that is removing the transparent pixels.

If you can point us to the source of where you’re copying from, that might also help.

I am copying from Preview. Here is an example PNG:

Interesting. I don’t have any problems copying that from Preview into Acorn - all the transparent edges are still there.

I’m wondering - maybe the original was a PDF or vector shape somehow? Are you absolutely sure it was originally a PNG that Preview opened up?

This is me copying from preview with transparent edges.

And this is what happens when I paste it into Acorn. The transparent edges are gone. If it worked for you, I am probably doing something wrong. I wish I knew what it is. I am absolutely sure that it was originally a PNG that Preview opened up as you see from the screenshot.

OH - it’s not that the transparent edges are gone, it’s that when you do a Scale and Rotate of a bitmap layer, Acorn will trim out the transparent edges of a layer so that you get the opaque bounds.

If you use File ▸ New from Clipboard in Acorn, then you’ll get your image with the transparent edges. Try that out!

If I do “new from clipboard,” it opens the image in another tab with the transparent edges. That’s all great and fine, but my problem is how to get Acorn to NOT trim out the transparent edges when I do a Scale and Rotate. I found a kind of tedious solution, and that is to go to preset selection, choose “square,” scale the height and width, center the PNG image in the center of that box, and then move it. Is there an easier solution?
