# imagefilledarc

(PHP 4 >= 4.0.6, PHP 5)

imagefilledarc — Draw a partial ellipse and fill it

### Beschreibung

bool imagefilledarc ( resource `$image` , int `$cx` , int `$cy` , int `$width` , int `$height` , int `$start` , int `$end` , int `$color` , int `$style` )

Draws a partial ellipse centered at the specified coordinate in the given `image` .

### Parameter-Liste

`image`

  Eine von den verschiedenen Erzeugungsfunktionen wie imagecreatetruecolor() gelieferte Grafikresource.

`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:

  1. `IMG_ARC_PIE`
  2. `IMG_ARC_CHORD`
  3. `IMG_ARC_NOFILL`
  4. `IMG_ARC_EDGED`
  `IMG_ARC_PIE` and `IMG_ARC_CHORD` are mutually exclusive; `IMG_ARC_CHORD` just connects the starting and ending angles with a straight line, while `IMG_ARC_PIE` produces a rounded edge. `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 (rather than fill) a 'pie slice'.

### Rückgabewerte

Gibt bei Erfolg `TRUE` zurück, im Fehlerfall `FALSE`.

### Beispiele

Beispiel #1 Creating a 3D looking pie

`<?php
// create image
$image = imagecreatetruecolor(100, 100);
// allocate some solors
$white = imagecolorallocate($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);
?>`
