It is faster than the built-in zoom effect and you can move the center. Enjoy !

Very good, null54!

If I convert this to IndirectUI, will you add it to the first post?

For some reason, after I copied the DLL to my PDN effects directory, it still didn't show up in my Effects>Blur menu. I built the plugin, myself, and it worked fine. Quite a nice effect, too.

 

In case anyone else has the same problem, here is my build: ZoomBlurDeluxe.zip

 

If no one else has the problem, I'll delete the attachment later.

Hmm, I had no issue with it.

It is faster than the built-in zoom effect...

In my unscientific testing (both effects at comparable settings) of several 5,000px x 5,000px photos, I found the built-in effect to be faster.

Still, this effect produces slightly different results compared to the built-in effect, so I think I'll keep it.

I have an old dll that crashed PDN and I also download the dll that didn't show up. I tested the one you just posted, it isn't quit the same, but that can be due to so many other things I understand that.

 

I'm about to try a tutorial to see what happens. Thank you so much for just seemingly just throwing one together.

Here's the icon:

 

EDIT: At toe_head2001's suggestion, I changed the blur range to 0-255. (toe_head2001 points out that in the original version it's 1-256, but I like the no-blur option, and somehow 255 seems to me to be more sensible as the top of the range. It's easy to change if someone insists it match the original.)

 

EDIT2: At toe_head2001's suggestion, I changed the blur default to 20. I missed that in my first edit. I also changed the top of the range to 256, because my reason for not doing so was silly. I left 0 as the lower range, because I do like the idea of being able to see the image with no blur. (I could make it a do so more efficiently by handling that as a special case.)

If I convert this to IndirectUI, will you add it to the first post?

Yes.

 

In my unscientific testing (both effects at comparable settings) of several 5,000px x 5,000px photos, I found the built-in effect to be faster.

 

That was copied from the original thread, it may have been faster when the effect was first posted in 2007.

I was just about to post that... you beat me to it.

 

 

Hey, look at this line:

int Amount1 = 10; // [0,100] Amount

The original source allowed for a zoom range of 1 - 256, and had a default of 20

 

 

Edit:

Here's the IndirectUI dll for those that want it.

Sorry, toe_head2001. I didn't post the CodeLab version so much so that someone could use it (since they can use the original), but just because I thought someone might use it as the basis for some other variation.

Thanks for this update.

Thanks for the update Null54. Thanks for the code MJW.

[Pixey 3,330]

It's working well and thank you Mr. Null

 

[doughty 308]

Good job Pixey, I was trying to do Yellowman's Wall Light a few days ago.

Thank you all for doing your bit at bringing this back.

[barbieq25 831]

Oh thank you so much! I have missed this terribly.

So do I need everything in both these zips to have the Zoom blur deluxe? And does it all go in Effects? Still learning this stuff....

[MJW 999]

Just the first. The second is the source code, of interest only to plugin programmers.
