imagedashedline — Draw a dashed line

### Description

bool imagedashedline ( resource `$image` , int `$x1` , int `$y1` , int `$x2` , int `$y2` , int `$color` )

This function is deprecated. Use combination of imagesetstyle() and imageline() instead.

### Parameters

`image`

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

`x1`

  Upper left x coordinate.

`y1`

  Upper left y coordinate 0, 0 is the top left corner of the image.

`x2`

  Bottom right x coordinate.

`y2`

  Bottom right y coordinate.

`color`

  The fill color. A color identifier created with imagecolorallocate().

### Return Values

Always returns true

### Examples

Example #1 imagedashedline() example

`<?php
// Create a 100x100 image
$im = imagecreatetruecolor(100, 100);
$white = imagecolorallocate($im, 0xFF, 0xFF, 0xFF);
// Draw a vertical dashed line
imagedashedline($im, 50, 25, 50, 75, $white);
// Save the image
imagepng($im, './dashedline.png');
imagedestroy($im);
?>`

The above example will output something similar to:

Example #2 Alternative to imagedashedline()

`<?php
// Create a 100x100 image
$im = imagecreatetruecolor(100, 100);
$white = imagecolorallocate($im, 0xFF, 0xFF, 0xFF);
// Define our style: First 4 pixels is white and the
// next 4 is transparent. This creates the dashed line effect
$style = Array(
$white,
$white,
$white,
$white,
IMG_COLOR_TRANSPARENT,
IMG_COLOR_TRANSPARENT,
IMG_COLOR_TRANSPARENT,
IMG_COLOR_TRANSPARENT
);
imagesetstyle($im, $style);
// Draw the dashed line
imageline($im, 50, 25, 50, 75, IMG_COLOR_STYLED);
// Save the image
imagepng($im, './imageline.png');
imagedestroy($im);
?>`
