imagefilledarc — Draw a partial arc and fill it
Description
imagefilledarc ( resource $image , int $cx , int $cy , int $width , int $height , int $start , int $end , int $color , int $style ) : bool
Draws a partial arc centered at the specified coordinate in the given image.
Parameters
-
image -
An image resource, returned by one of the image creation functions, such as imagecreatetruecolor().
-
cx -
x-coordinate of the center.
-
cy -
y-coordinate of the center.
-
width -
The arc width.
-
height -
The arc height.
-
start -
The arc start angle, in degrees.
-
end -
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_PIEIMG_ARC_CHORDIMG_ARC_NOFILLIMG_ARC_EDGED
IMG_ARC_PIEandIMG_ARC_CHORDare mutually exclusive;IMG_ARC_CHORDjust connects the starting and ending angles with a straight line, whileIMG_ARC_PIEproduces a rounded edge.IMG_ARC_NOFILLindicates that the arc or chord should be outlined, not filled.IMG_ARC_EDGED, used together withIMG_ARC_NOFILL, indicates that the beginning and ending angles should be connected to the center - this is a good way to outline (rather than fill) a 'pie slice'.
Return Values
Returns true on success or false on failure.
Examples
Example #1 Creating a 3D looking pie
<?php
// create image
$image = imagecreatetruecolor(100, 100);
// allocate some colors
$white = imagecolorallocate($image, 0xFF, 0xFF, 0xFF);
$gray = imagecolorallocate($image, 0xC0, 0xC0, 0xC0);
$darkgray = imagecolorallocate($image, 0x90, 0x90, 0x90);
$navy = imagecolorallocate($image, 0x00, 0x00, 0x80);
$darknavy = imagecolorallocate($image, 0x00, 0x00, 0x50);
$red = imagecolorallocate($image, 0xFF, 0x00, 0x00);
$darkred = imagecolorallocate($image, 0x90, 0x00, 0x00);
// make the 3D effect
for ($i = 60; $i > 50; $i--) {
imagefilledarc($image, 50, $i, 100, 50, 0, 45, $darknavy, IMG_ARC_PIE);
imagefilledarc($image, 50, $i, 100, 50, 45, 75 , $darkgray, IMG_ARC_PIE);
imagefilledarc($image, 50, $i, 100, 50, 75, 360 , $darkred, IMG_ARC_PIE);
}
imagefilledarc($image, 50, 50, 100, 50, 0, 45, $navy, IMG_ARC_PIE);
imagefilledarc($image, 50, 50, 100, 50, 45, 75 , $gray, IMG_ARC_PIE);
imagefilledarc($image, 50, 50, 100, 50, 75, 360 , $red, IMG_ARC_PIE);
// flush image
header('Content-type: image/png');
imagepng($image);
imagedestroy($image);
