imagesetthickness - Set the thickness for line drawing

SYNOPSIS

       bool imagesetthickness (resource  $image, int  $thickness)

DESCRIPTION

       imagesetthickness(3) sets the thickness of the lines drawn when drawing rectangles, polygons, ellipses etc. etc. to $thickness pixels.

PARAMETERS

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

	      o $thickness
		- Thickness, in pixels.

RETURN VALUES

	Returns TRUE on success or FALSE on failure.

EXAMPLES

       Example #1

	      imagesetthickness(3) example

	      <?php
	      // Create a 200x100 image
	      $im = imagecreatetruecolor(200, 100);
	      $white = imagecolorallocate($im, 0xFF, 0xFF, 0xFF);
	      $black = imagecolorallocate($im, 0x00, 0x00, 0x00);

	      // Set the background to be white
	      imagefilledrectangle($im, 0, 0, 299, 99, $white);

	      // Set the line thickness to 5
	      imagesetthickness($im, 5);

	      // Draw the rectangle
	      imagerectangle($im, 14, 14, 185, 85, $black);

	      // Output image to the browser
	      header('Content-Type: image/png');

	      imagepng($im);
	      imagedestroy($im);
	      ?>

	      The above example will output something similar to:[NOT DISPLAYABLE MEDIA]Output of example : imagesetthickness()

imagelayereffect - Set the alpha blending flag to use the bundled libgd layering effects

SYNOPSIS

       bool imagelayereffect (resource	$image, int  $effect)

DESCRIPTION

	Set the alpha blending flag to use the bundled libgd layering effects.

PARAMETERS

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

	      o $effect
		- One of the following constants:

		     o IMG_EFFECT_REPLACE - Use pixel replacement (equivalent of passing TRUE to imagealphablending(3))

		     o IMG_EFFECT_ALPHABLEND - Use normal pixel blending (equivalent of passing FALSE to imagealphablending(3))

		     o IMG_EFFECT_NORMAL - Same as IMG_EFFECT_ALPHABLEND.

		     o IMG_EFFECT_OVERLAY  -  Overlay  has the effect that black background pixels will remain black, white background pixels will
		       remain white, but grey background pixels will take the colour of the foreground pixel.

RETURN VALUES

	Returns TRUE on success or FALSE on failure.

EXAMPLES

       Example #1

	      imagelayereffect(3) example

	      <?php
	      // Setup an image
	      $im = imagecreatetruecolor(100, 100);

	      // Set a background
	      imagefilledrectangle($im, 0, 0, 100, 100, imagecolorallocate($im, 220, 220, 220));

	      // Apply the overlay alpha blending flag
	      imagelayereffect($im, IMG_EFFECT_OVERLAY);

	      // Draw two grey ellipses
	      imagefilledellipse($im, 50, 50, 40, 40, imagecolorallocate($im, 100, 255, 100));
	      imagefilledellipse($im, 50, 50, 50, 80, imagecolorallocate($im, 100, 100, 255));
	      imagefilledellipse($im, 50, 50, 80, 50, imagecolorallocate($im, 255, 100, 100));

	      // Output
	      header('Content-type: image/png');

	      imagepng($im);
	      imagedestroy($im);
	      ?>
