Hi!

I work on a contour (isolines) of a random matrix. Can I do it using "ImageEn" or it can be possible if points of the contour are known?

Best regards,
Konstantin

Sorry Konstantin,

Can you give me a link that describes this process in more detail?

Hi

I'm afraid that is not supported by ImageEn.

Is something changed in that case by years? It is used so often in the scientific area, so it can make extension to the the ImageEn usability :) By the way I also look at this. :)

Hi Piotr

Do you know of any code samples or libraries that show the technique to generate this?

Hi, of cource yes. From the begining I know tree algorithms for that: Marching squares, Delaunay Triangulation and Conrec. Many years ago I create something like that for myself when I create a software for Thermography. I can send You it on priv. You can look also: http://anfilat.chat.ru/tpcolore.htm

Hi Piotr

I've discussed this with my partner.

We decided that its probably not quite in the area of ImageEn. Also, it doesn't need ImageEn to work, so we're not really adding any value to it.

You might want to suggest it on our UserVoice page:

Ok, I understand. I try to find other method to draw it on the layer as I made it by use a Graphics32 component years ago.

Hi Piotr

Naturally, the easiest way is just to draw onto a bitmap and assign it to your layer, but if you need something more complex, e.g. to handle the layer being sized, custom draw the layer. There is a demo for this, but if the process to create the plot is slow, you might want to keep a local copy of it.
