imagesetthickness — Set the thickness for line drawing

### Description

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().

`thickness`

  Thickness, in pixels.

### Return Values

Always returns `true`.

### Changelog

Version | Description

8.0.0 | `image` expects a GdImage instance now; previously, a valid `gd` resource was expected.

### 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, 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);
?>`

The above example will output something similar to:

`↑` and `↓` to navigate • `Enter` to select • `Esc` to close • `/` to open
