Hello, I'm using MAGICK.NET There are some questions I would like to ask you. I wonder if it is convenient for you?
Sorry, my English is not very good

I want to use MAGICK.NET How to replace the region color of the image?
I'm using draw now, but I don't think it's very efficient

Can you clarify what the region color is? And feel free to share some of your current code so I can understand beter what you are trying to do.

For example, I specify a rectangular area on the image and fill it with white

[jueqing1015]

Drawables s = new Drawables();
s.Rectangle(new Rectangle(0, 0, 100, image.Height));
s.FillColor(Color.White);
s.Draw(image);
I'm using this method now

[dlemstra]

This is actually a pretty efficient method to do this. Another method would be to create an image that is 100 x image.height and the use Composite to draw it over the other image. Not sure which one is faster though.
