Minimum Blur

[p_mac]

Minimum blur seems to have an issue.  Is that black and white rim normal?  Sure would be nice to be able to upload videos 

protect alpha, no circular - black rim

Protect alpha - circular enabled

Protect alpha not enabled

If you mean videos from your iPad to show what’s happening, you can do that easily in any recent version of iOS. Swipe down and left from the top right-hand corner of the screen, tap on the ‘Record’ button and then tap elsewhere to dismiss the control centre. Swipe down and tap the ‘Record’ button again to stop. Go to the Photos app to view and edit the screen recording, and then attach it here in the usual way.

Thank you Alfred for your reply, but as you know, I am well aware of how to screen capture as you have viewed some of my uploaded videos.  

The comment was about the attempt to upload videos, even very small ones, that are not uploading to this site.  I am commenting on that.

The mods seem to want more than the detailed descriptions that I am trying to provided, yikes, so I am trying to be so detailed so that they will pay attention, but I muse as to whether I am being blocked from doing this.  I seem to be getting the B/W screen that says that I need to contact them to get help in uploading.  

The AP for iPad is, my opinion, a daunting mess and I am trying to help them to fix this.  

Any suggestions on why this live filter is acting this way would be more a help.

I couldn’t remember. Sorry!  I wrote “If you mean...” to indicate that I wasn’t sure.

I had that B&W screen a day or two ago, but the upload worked the next time I tried it. I don’t think I did anything different the second time around!

I’m afraid I’ve no idea why it’s misbehaving.

Hey p_mac,

It looks right to me. Minimum Blur is supposed to broaden dark areas so where your image meets the transparent area it is seemingly broadening the coloured pixels and causing an outline effect.

Thanks for that explanation about darkening the areas.  Sounds reasonable.

But the original image had no transparent area around the perimeter prior to the application of the Minimum Blur.  I was interested in why Protect Alpha was not protecting the perimeter area of the image after the filter was applied because I was under the impression that is what Protect Alpha was supposed to do.  When Protect Alpha is not enabled, I understand the transparent perimeter, but when it is enabled should the perimeter area still be transparent?

When you're applying the Minimum Blur, the perimeter or edges of the image are being blurred causing transparency to occur. Enabling Protect Alpha tries to protect the edges from this transparency and is causing a black band to appear (where the effect is broadening the pixels that meet the transparency. I think we agree that this is true and working.

However, I've just taken another look at your second screenshot and it seems that enabling Circular is negating the Preserve Alpha. As far as I know, Circular should just change the darkened areas to circles so I'm a bit unsure if this is correct behaviour or not so I will have to query this with the developers. To me, it just looks like Circular is turning off Protect Alpha.
