imagesetthickness — Set the thickness for line drawing

### Description

function imagesetthickness(GdImage `$image`, int `$thickness`): true

imagesetthickness() sets the thickness of the lines drawn when drawing rectangles, polygons, arcs etc. to `thickness` pixels.

### Parameters

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

### Examples

Example #1 imagesetthickness() 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, 199, 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);
    ?>
