Bitmap Clone

SITCore

Good Morning. I am trying to use the Clone method in the Bitmap class. What I am seeing on the internet is that this should be part of the .NET framework. However, digging into the GHI firmware, I am seeing this in the Image class:
Capture

Is the method usable in some other namespace or something? What am I supposed to do if I just want to extract a smaller portion of my bitmap?

I do see a GetPixel method in the Bitmap class. Am I supposed to use a loop to extract 1 pixel at a time and build a new bitmap?

Any help here will be appreciated.
Thanks.

Unfortunately we can’t include every feature from the full framework. We need to keep the firmware size manageable.

What are you trying to achieve?

I am using USB host to use a mouse cursor on a screen. My screen is 800x480. The refresh rate is about 10hz and it looks really bad. I am trying to use a dirty rectangles approach to speed up the refresh rate.

if I remember correctly, it is around 100fps for 480x272, and it is about ~30fps for 800x480 when refresh the screen.

10fps is slow, I think it needs some optimizes then.
