Perspective Effect (v2.0 update 03/05/'10)

[dpy]

Hi ,

Perspective Effect　was completed!

The perspective effect of　this plugin is the same as it of photoshop as far as I tested this plugin .

Of course you can use the conventional trapezoid transformation, too.

If you find bug , please tell me.

I will add this version to a set pack two weeks later.

MENU

Effectｓ->Distort->Perspective

Interface

Ratio1-3

transform to perspective or trapezoid by three adjustment.

scale 0.01-16.0

Vertical/Horizontal and Perspective/Trapezoid

select vertical or horizontal.

Example　of Vertical:Normal how to use

Example of Horizontal:

Linked Ratio1 and Ratio2

Ratio2 is ignored.

High Quality

Please uncheck if you feels work is slow. Please check it after finishing resize.

Download　

This is made by "Code Lab".

Thank you , BoltBait.

ver2.0 add perspective transform (03/05/'10)

ver1.1 take Antialiasing(02/16/'10)

ver beta only trapezoid transform (09/16/'09)

Wow! :shock:

This must be one of the best things since like...ever!

Edit: And it's fast! Even with a 2000x1500 px image! :shock:

[Boude]

Very nice, you made a resizing algorithm and you managed to apply it, a thing I still have on my To-Do list.

[007 Nab]

Very nice plugin! Thank you for sharing it!

[dpy]

Thank you for comment.

I am not a programmer and I do not know C # well .

However , Thanks to　"CodeLab" , I can create plugin which is necessary for me, and I am glad that you like my plugin.

To Boude

Thank you for Lesson of the other day . :wink:

Im a little confused on what it does, does someone mind explaining it?

[Ego Eram Reputo]

Think of the effect as squashing or stretching the height or width of the image.

See the first image posted? The buildings look like they're leaning inwards at the top. The second image has corrected this by stretching the top of the image slightly.

[dpy]

thank you , EER .

BTW , I found my big mistake.

This is not perspective! :oops:

[kartracer]

Thank You very much !!!

Have been hoping to find something like this.

Thanks Again!!

Yes, excellent plug in. Just what was needed.

[dpy]

To kartracer , Goonfella

I'm glad you like this plug-in.

[Whizzy]

I have some of your effects now and love them, gonna try this one as well

don't worry about your bad english, guess with your contribution to our creativity we all forgive you

[Neil Cassidy]

This is great dpy, thanks!

It seems like you could add a real skew effect as well, thanks to the difference between "perspective" and "dpy perspective" that you mentioned above. That would be fantastic. There's already an effect that does this (called "octagonal/quad reshape/matte"), but it can be tricky to get the shape right every time. I always have to load up Paint when I need to do it.

[dpy]

To Whizzy,Neil Cassidy

you are welcome.

although a fake perspective.

[Lance McKnight]

I love this plugin! I was able to make this image using this plugin in tandem with Rotate/Zoom.

[007 Nab]

Oh yeah - following that PSD TUT from a while ago- hah

This plugin is made for it

I always wanted to try that one out - I like your result

[Wilson]

Nice plugin, dpy!

[Lance McKnight]

dpy, any way you can add anti-aliasing option? That would make all the edge smooth when running the plugin.

[gregors]

Thanks for the Perspective (Beta) I've been looking for that distortion since I installed Paint.NET.

Although I would prefer a graphic interface where the corners of a bounding box are moved to effectuate the perspective distortion I realize that such a plugin is an entirely different (and more difficult) development.

This works just great!

I do have corrections to the language and some other suggestions if you would like, (see image)

Thanks again!

Lance and gregors

Thank you for suggestions.

I'd like to do so , but I can't do , because I'm Beginner of programing.

About anti-aliasing

pyjo's Basic Antialiasis so good.

When I was creating Perspective Effect , I tried to add it .

but , I could not work it :oops:

About UI

All my plugins were created by code Lab.

To change UI , I must study Visual C# .But I have no time to study it now. :oops:

However　,　 I'd like to do update , someday

[Boude]

@dpy: anti-aliasing is controlled blurring, and blurring is quite easy, it's mixing colours. So an average blur with a radius of 1 might look something like this:

CurrentPixel.R=(src[x+1,y+1].R+src[x,y+1].R+src[x-1,y+1].R+src[x+1,y].R+src[x,y].R+src[x-1,y].R+src[x+1,y-1].R+src[x,y-1].R+src[x-1,y-1].R)/9; //repeat for Green, Blue and Alpha

A more complicated blur would consider pixel further away as less important, so a your CurrentPixel would have less information from src[x+5,y+5] then src[x+1,y]. For a more controlled blur you could use the alpha value to search for edges, for example:

if (Math.Abs(src[x,y]-src[x-1,y])>100) //Math.Abs() is a method to make sure your value is positive, it convert negative numbers to positive numbers, which in this case comes in handy.
{
//Blur code
}

Wow ! it seems to be easy and simple !Thank you , Boude

But , i am so busy now I'll try it later.

Boude , Can I ask you to update for anti-aliasing?

If you are OK , change UI too.

What do you think?

[Boude]

Thanks, I would be honoured. I already have a simple blur working so I guess this should be do-able.

[dpy]

I am looking forward to up date by you

[dpy]

up date.

I added anti-aliasing by bilinear.

please test.

Boude , always thank you.

this time , I don't use your idea ,

but , I used your idea to create other plugin . :wink:
