imagefilledarc - Draw a partial arc and fill it

SYNOPSIS

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

DESCRIPTION

	Draws a partial arc centered at the specified coordinate in the given $image.

PARAMETERS

	      o $
		image -An image resource, returned by one of the image creation functions, such as imagecreatetruecolor(3).

	      o $cx
		- x-coordinate of the center.

	      o $cy
		- y-coordinate of the center.

	      o $width
		- The arc width.

	      o $height
		- The arc height.

	      o $start
		- The arc start angle, in degrees.

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

	      o $color
		- A color identifier created with imagecolorallocate(3).

	      o $style
		- A bitwise OR of the following possibilities:

		     o IMG_ARC_PIE

		     o IMG_ARC_CHORD

		     o IMG_ARC_NOFILL

		     o 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'.

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);
	      ?>

	      The above example will output something similar to:[NOT DISPLAYABLE MEDIA]Output of example : Creating a 3D looking pie

DESCRIPTION

       imagewbmp(3) outputs or save a WBMP version of the given $image.

PARAMETERS

	      o $
		image -An image resource, returned by one of the image creation functions, such as imagecreatetruecolor(3).

	      o $filename
		-The path to save the file to. If not set or NULL, the raw image stream will be outputted directly.

	      o $foreground
		-  You	can set the foreground color with this parameter by setting an identifier obtained from imagecolorallocate(3). The default
		foreground color is black.

RETURN VALUES

	Returns TRUE on success or FALSE on failure.

EXAMPLES

       Example #1

	      Outputting a WBMP image

	      <?php
	      // Create a blank image and add some text
	      $im = imagecreatetruecolor(120, 20);
	      $text_color = imagecolorallocate($im, 233, 14, 91);
	      imagestring($im, 1, 5, 5,  'A Simple Text String', $text_color);

	      // Set the content type header - in this case image/vnd.wap.wbmp
	      // Hint: see image_type_to_mime_type() for content-types
	      header('Content-Type: image/vnd.wap.wbmp');

	      // Output the image
	      imagewbmp($im);

	      // Free up memory
	      imagedestroy($im);
	      ?>

       Example #2

	      Saving the WBMP image

	      <?php
	      // Create a blank image and add some text
	      $im = imagecreatetruecolor(120, 20);
	      $text_color = imagecolorallocate($im, 233, 14, 91);
	      imagestring($im, 1, 5, 5,  'A Simple Text String', $text_color);

	      // Save the image
	      imagewbmp($im, 'simpletext.wbmp');

	      imagewbmp($im, NULL, $foreground_color);

	      // Free up memory
	      imagedestroy($im);
