For an image I am doing right now, I wanted to use the Alpha blur, for some fading effect, now, a part of the selection does not blur, I do not know If I do something wrong or that there is a bug... I'll show you: I started off with this one. a background and a woman (both on a different layer  Now I added a new layer - copied a small selection from the background and added it on the layer on top of the woman as shown here :  I got the rectangle select tool from around middle height till bottom of the image (to speed up) and set the alpha blur setting to 45, and next is the result of that:  you see in the right corner it's not been blurred, even if I set the settings to 100 that part does not blur at all... After testing all of my blurs (16 blurs; think I have them all) just the Alpha blur and Gaussian blur + gave me this weird results on the right bottom corner... |

Ais, did you post this on the main forum in the relevant plugin? I am sure one of the plugin developers could help you. I really don't know.

How strange. I`d do what Barbie suggested if I were you and post the problem in the relevant plug in thread on the main forum.

She did. Then I prompter her to cross post and she included it here as well ...
Only thing that has come to mind is what the point of origin for the radius calculations may be starting at ... I'm still trying really hard not to open up Visual Studio or even code lab but curiosity is really starting to get to me on some of these things ...
Just mentioning the other ahead of time as there was a pretty big echo and that developer hasn't been around for some time. Though with Gaussian+ ... Now that's something maybe that can be addressed in real time. Maybe. ...
Righto. Just babbling while I'm pondering the paint on my hands. Not from art ... just the ceiling in my shop. Was way too dark. Now its white. Lots more light. Works out well for plants and people oddly enough.

lol you have a flower shop delpart?
to get back to the issue, yes I posted it at Tanel's photo and color plugins 2 days ago... and it was just yesterday that delpart answered... and yes posted it on here to because I am starting to get nuts here... it's the only thing I still have to do on this painting and I just can not finish it....
With all the other tools (including smudge) you don't get the same result as with alpha blur... actually is that one really really necessary....

Odd I thought pyro would have answered that at least. Come to think if it - haven't seen much of him at all lately.
Flowershop? Nursery? I love plants!

I better "nip that one in the bud" right now ... ;D ;D ;D
No, just my tools/work-shop for the house. One window on the shady side of the house with hurricane shutters blocking even more light and the door is also under shadow ...
The plants reference is just from too many years of doing this and that. Including helping with indoor and nearly indoor growing of various plants. Flat white paint makes an easy to repair/replace reflective coating and maximizes the output of light sources to make plants happy. And for people it helps with aging eyes to reduce strain ... especially when playing with things like a grinding wheel or a high-speed drill like a Dremel where you value your fingers. ;D
Around here I'm pretty spoiled since all my "house plants" can live outside for about 11 months of the year. Or a full 12 with some careful covering and TLC from time to time ...
Still learning what salt air will or will not kill etc though. Coming from the desert primarily to this overtly humid environment still leaves me puzzled over lots of things. For instance, I've simply grown to hate anything made of metal now ... I swear even the wood rusts here.
Righto, just figured I'd keep you from thinking I was an indoor grower of anything (illicit or otherwise) at the moment, or a florist, etc ... Though if I just had the resources and financial cushion, with my background covering a lot more than computers, I'd try my hand about now in growing things for a living. Slow results, but at least they are more tangible than most of what the likes of me do ... Sort of like mowing a lawn; instant appreciation of a job well done by pretty much anyone ... and especially one's self.
(Now I'm going to be dreaming of running large greenhouses again. ;D )

@ aislin, I just replied in the main forum, I am sure I am seeing too different selections in the last two images? Are you getting same result when not using the rectangle selection, I mean just apply the blurs on the whole layer?

Okey, I'll post it up here first: a screenshot of pdn, while doing alpha blur (I first finished all the rest of the image and put all that in one layer, otherwise it would have been too much) and yes, that is my entire screen, two screens actually, the one I use pdn for is a computer flat screen and the one where you can see my desktop is my acer aspire one, where pdn is running on   |

Resolved (the image viewing that is), thank you.

by the way... with gaussianblur + it comes with this weird result ONLY if I set the setting to: Alpha channel only

hated the waiting, so I fixed it in a different way... I erased the part with the weird result, copied a good part, pasted it on a diff layer, and stretched it with the selection tool... so it looks a lot what I had in mind ;-)

Ais, I wonder if the bug is because the original is written for a version younger than the PDN we are using now?

it might be... I have no idea... but it seems the problem is just with Alpha... because when I tested gaussian + again it all worked well, except for the Alpha Channel Only.... So it must be Alpha then right?

Yes, Alpha channel anything with PDN is a real mess on some levels ... This is not an expert opinion, but I've done some reading on the various editors and read some rather interesting rants here and there about how its done pragmatically.
A good example of weird alpha channel headache can be seen where it is used to position things with the Align tools in PDN. If you use AlphaSpace on an object that has been centered against a transparent background you'll see they used the alpha channel to move it ... That's not really indicative of the other issues with how PDN's code approaches the alpha at its root, but I found it really interesting. That strange thing shows up for me with most of the emboss tools etc. "Where is that edge coming from?" 5 hours later ... "Ah-HA! So that's how that works ... " ;D
There's also a strange threshold issue with Alpha as well. If I recall its only effect on certain saturation ranges (which is what you want) but depending on the tool and how its rendered (PDN renders all layers at once at any given time) will affect the tool's ability to modify or adjust adjacent pixels ... This is why I'm still thinking it has to do with it being a layer focus/origin issue with Alpha Blur even though it is setup to work with selections. (Note, not all tools work with selections the way they should in the PDN-verse ...)
**Humor inclined Disclaimer: I'm far from being the expert mind you. I'm still trying to understand the tools waaaaaay too much instead of just focusing on how to use them. Also, just sharing my rambling thoughts so I can get them out of my head. If I dont get them out of my head, then I'm stuck with them for hours and it gets really annoying to be arguing with yourself like I do ...
