I tawt I taw a puddy tat!

Just to be clear, rectangular image become ellipsoid, and square become circular.

Cool name for the plugin!

[DrewDale]

Cool plugin TR. Great fun and a great name too.

[TechnoRobbo]

Ego,

 

you did , you did taw a puddy tat

 

Drew,

 

cool - reflection makes it work.

[Seerose]

TechnoRobbo!   Thank you so much for this Plugins and for the effort. 

 

[TechnoRobbo]

Nice Seerose - took me second to figure it out- you kept hitting Ctrl-F.

A very good plug in, I have used it as inspiration for the sig of the week#103. I can see a lot of potential use with this. Thank you TechnoRobbo. 

[mottoman]

Much fun. Thank you TR.

for the effect on the lower image - I ran drum skin, then trial and then drum skin one more time.

Nice example images from DrewDale, Seerose and Lloyd also.

[nitenurse79]

Brilliant plug in Techno. And some very creative examples shown here too. Love your plug in's  

Here's one. Using the first part of  This Tutorial from Welshblue. Adding a clock face, then playing with this plug in, I have come up with
a modern day salvador dali creation

NiteNurse - Brilliant - I'd give you a rep but my daily quota is up. I'll get you tomorrow

Awww. Bless you

[TechnoRobbo]

Motto and Llyod - extremely creative 

 

Motto - that bottom one is wild.

[Ego Eram Reputo]

If I may be so bold.....

With a couple of little changes to your code, the image can be further distorted to get a round result from a rectangular canvas. I took the liberty and added two controls, Height and Width.

These can be used as a pseudo resize if you don't want the result to fill the canvas to the edges.

And if I may be so bold as to incorporate your code and add magnification sliders and include your name in the Title

 

TR's & EER's Drumskin Version 1.3 uploaded.

[mottoman]

Do you still have the first version of this ? The new version is no longer showing in V3.5.11. 

Edited March 26, 2014 by mottoman

[Goonfella]

I have the same problem. I have tried installing this twice and even though it is listed in the PDN Effects file it does not show up in the program . The previous version was fine.

[Ego Eram Reputo]

And if I may be so bold as to incorporate your code ..... and include your name in the Title

 

You have my permission (and thanks)  I don't really think my little bit of code should grant me co-authorship - I'm still bewildered by the remapping code

 

 

 

even though it is listed in the PDN Effects file it does not show up in the program

 

@ TR - have you ported the CodeLab source to VS?

[Lloyd]

Also I have the same problems as mottoman an Goonfella. New version is in the effects folder, but no show in the menu

[TechnoRobbo]

Sorry, I think the confusion is the name change the new one will appear as

 

 

 

it was compiled under vista to be 3.5 compatible - sorry again

 

 

 

 

 I don't really think my little bit of code should grant me co-authorship - I'm still bewildered by the remapping code - EGO

Heck I didn't come up with the algorithm - Pythagoras did.

[mottoman]

These are the only TR plugin's I have in the Distort sub menu Drum skin is not showing.

Even though it is in my effects folder (downloaded again Today) 

 

Do you have the first version of this you could maybe upload again?

[DrewDale]

Same here, no longer showing in the menu for me either PDN-3.5.11. 

[TechnoRobbo]

My apologies again - I must have messed up moving it from Windows 7 to my NAS drive to my Vista back to my NAS back to my Windows7 

 

I uploaded v1.4 is should look like this

[Seerose]

Thank you again. It worked.     

[mottoman]

Happy to see it working again. Thank you again TR & EER for the new tweaks.

[DrewDale]

Nice job TechnoRobbo / EER. It runs and works perfectly now. Nice new additions too.
