is paint.net using pure .net code(what language?) developed?

[penua]

Hello,

I have some trouble on my image programming with C#, because the process speed of c# is too slow.

so, i wanna know is paint.net using pure .net code(what language?) developed?

C# is not too slow, it depends on how you use it

If you use GetPixel and/or SetPixel, stop doing that immediately. Instead, just lock the bitmap once and use unsafe code to change the pixel data. Don't forget to unlock when you're done.

I really doubt that you're doing that now, since it isn't slow at all

PDN is pure .NET (except the shell integration and installer, right?)

Also, once you lock the bitmap, you can use GDI+
