imagefilledarc · Image · PHP

Draw a partial arc and fill it

Syntax

imagefilledarc(
    GdImage $image,
    int $center_x,
    int $center_y,
    int $width,
    int $height,
    int $start_angle,
    int $end_angle,
    int $color,
    int $style
): bool

Parameters

image

A GdImage object, returned by one of the image creation functions, such as imagecreatetruecolor().

center_x

x-coordinate of the center.

center_y

y-coordinate of the center.

width

The arc width.

height

The arc height.

start_angle

The arc start angle, in degrees.

end_angle

The arc end angle, in degrees. 0° is located at the three-o'clock position, and the arc is drawn clockwise.

color

A color identifier created with imagecolorallocate().

style

A bitwise OR of the following possibilities: IMG_ARC_PIE, IMG_ARC_CHORD, IMG_ARC_NOFILL, and IMG_ARC_EDGED.

IMG_ARC_PIE produces a rounded edge. IMG_ARC_CHORD connects the starting and ending angles with a straight line. IMG_ARC_NOFILL indicates that the arc or chord should be outlined, not filled. IMG_ARC_EDGED, used together with IMG_ARC_NOFILL, indicates that the beginning and ending angles should be connected to the center - this is a good way to outline a 'pie slice'.
