Bitmap.SetPixel

[Atmapuri]

Hi!

I was profiling a drawing applicationa and Bitmap.SetPixel
is consuming 90% of all CPU. Is there an alternative way
to create the bitmap and fill it with data that is stored
in an array of doubles?

Thanks!

Yes; LockBits; see http://www.bobpowell.net/lockingbits.htm

Hi Atmapuri,

Yes, you can write directly using LockBits and unsafe code blocks.
See Bob Powells GDI+ Faq for a description on how to do this.
