TftEllipseG() | TFT & EPD Graphic Library 2

Syntax

TftEllipseG(wX_Center As Word, wY_Center As Word, bRadiusH As Word, bRadiusV As Word, wStartColor As Word, wEndColor As Word, bGradient As Byte)

Parameters

Parameter	Description
wX_Center	X-coordinate of the ellipse center
wY_Center	Y-coordinate of the ellipse center
bRadiusH	Horizontal radius of the ellipse (in pixels)
bRadiusV	Vertical radius of the ellipse (in pixels)
wStartColor	Start color for the gradient, in 16-bit RGB565 format
wEndColor	End color for the gradient, in 16-bit RGB565 format
bGradient	Direction of the gradient: 0: Horizontal (Left to Right) 1: Vertical (Bottom to Top) 2: Radial (Center to Peripheral)

Overview

Draws an ellipse filled with a gradient color.

The gradient can be horizontal, vertical, or radial. The gradient will smoothly transition between the start and end colors.
If bGradient is set to 2, the radial gradient will be drawn from the center to the outer edges of the ellipse, but this method is computationally intensive and drawn pixel by pixel, making it slow.

Notes

Radial gradients are very computationally demanding and are drawn pixel by pixel, which can result in slower performance.
