How to fill gradient colors in a rectangle?(gradient effect may be lenear, diagonal,

9 New Member
Hi, i want to create a function to draw the gradient bars on TFT screen. So, can any one knows how much i have to increase/decreasee the color value in each step/in multiple steps.
I am thinking that based on the sizes of bar, you have to calculate the step size. ??
