Im a fan of pixel art, here is a turtle using GDI+ by tic
but the problem is that draw it pixel by pixel, am I doing it this right?
second, I tried resizing it, but it is blurry.
Is there a way to turn off antialiasing?
I want sharp corners not burry-rounded ones! :mrgreen:
thank you for any help and suggestions about the methods to be using this
to draw pixel art!

I am open to any comments!

My advice is to scan the pixels, multiply it by ten and redraw.

No 3 is default
0 is none

You need setting of interpolation mode to 5:

Gdip_SetInterpolationMode(G, 5)

I only tried it with png file as input.

The InterpolationMode enumeration specifies the algorithm that is used when images are scaled or rotated.
