Syntax

TftCircleN(wX_Center As Word, wY_Center As Word, bRadius As Word, pSolid As Bit, wColor As Word, bWidth As Byte, sbDirection As SByte)

Parameters

Parameter	Description
wX_Center	X-coordinate of the circle's center
wY_Center	Y-coordinate of the circle's center
bRadius	Radius of the circle (in pixels)
pSolid	Circle fill type: 0: No fill (outline only) 1: Solid fill
wColor	Circle color in 16-bit RGB565 format
bWidth	Circle's outline width in pixels: 0: No additional width (default, 1 pixel wide)

Overview

Any positive value: Outline width in pixels

sbDirection — Direction for outline width:

1: Outward (expands the circle)
-1: Inward (shrinks the circle)
Any other value: No additional width (ignored)

Draws a circle with customizable outline width and fill.

The fill can either be solid or absent (outline only), and the outline width can be adjusted both inward or outward, depending on the desired visual effect.

Notes

The bWidth and sbDirection options allow for precise control over the appearance of the circle's outline.
If no additional width is required, the default behavior is to draw a circle with a 1-pixel outline.
