Used to limit painting operations to even, odd, or every other pixel. The pixel in the upper left corner of the image (0,0) is an odd pixel. All other pixels are calculated odd or even from this origin. The "every other" pixel option paints the pixel directly under than drawing tool and calculates remaining pixels from that origin.
Pixels | Effect |
All | Color is applied to all areas a tool operates on. |
Every other | Color is applied to every other pixel starting with the pixel that the mouse button was pressed over. |
Even | Color is applied to every other pixel based on row and column. |
Odd | Color is applied to every other pixel based on row and column. |
