imagejpeg - Output image to browser or file

SYNOPSIS
bool imagejpeg (resource $image, [string $filename], [int $quality]) DESCRIPTION
imagejpeg(3) creates a JPEG file from the given $image. PARAMETERS
o $ image -An image resource, returned by one of the image creation functions, such as imagecreatetruecolor(3). o $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. o $quality -$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:[NOT DISPLAYABLE MEDIA]Output of example : Outputting a JPEG image 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(3). SEE ALSO
