# imagejpeg

(PHP 4, PHP 5)

imagejpeg — Output image to browser or file

### Description

bool imagejpeg ( resource `$image` [, string `$filename` [, int `$quality` ]] )

imagejpeg() creates a JPEG file from the given `image`.

### Parameters

`image`

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

`filename`

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

  To skip this argument in order to provide the `quality` parameter, use `NULL`.

`quality`

  `quality` is optional, and ranges from 0 (worst quality, smaller file) to 100 (best quality, biggest file). The default is the default IJG quality value (about 75).

### Return Values

Returns `TRUE` on success or `FALSE` on failure.

### Examples

Example #1 Outputting a JPEG 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', $text_color);
// Set the content type header - in this case image/jpeg
header('Content-type: image/jpeg');
// Output the image
imagejpeg($im);
// Free up memory
imagedestroy($im);
?>`

The above example will output something similar to:

Example #2 Saving a JPEG 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', $text_color);
// Save the image as 'simpletext.jpg'
imagejpeg($im, 'simpletext.jpg');
// Free up memory
imagedestroy($im);
?>`

Example #3 Outputting the image at 75% quality

`<?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', $text_color);
// Set the content type header - in this case image/jpeg
header('Content-type: image/jpeg');
// Skip the filename parameter using NULL, then set the quality to 75%
imagejpeg($im, NULL, 75);
// Free up memory
imagedestroy($im);
?>`

### Notes

> Note: JPEG support is only available if PHP was compiled against GD-1.8 or later.

> Note: If you want to output Progressive JPEGs, you need to set interlacing on with imageinterlace().
