to change color for a pixel in the screen you use SetPixel, but that requires lots of validations and if you use it in a screen of 1000 x 1000 that means you run one million redundant or unnecessary validations. Is there a faster way to change the color of a pixel?

    Hi, @VooDooChicken

    Please refer to the similar thread: SetPixel is too slow. Is there a faster way to draw to bitmap

    You can lock the bitmap data and use pointers to manually set the values. It's much faster. Though you'll have to use unsafe code.

    WINAPI Bitmap::LockBits method:
    The Bitmap::LockBits method locks a rectangular portion of this bitmap and provides a temporary buffer that you can use to read or write pixel data in a specified format. Any pixel data that you write to the buffer is copied to the Bitmap object when you call Bitmap::UnlockBits

    Best regards,
