IMAGEGIF(3) 1 IMAGEGIF(3)imagegif - Output image to browser or fileSYNOPSIS
bool imagegif (resource $image, [string $filename])
DESCRIPTION imagegif(3) creates the GIF file in filename from the image $image. The $image argument is the return from the imagecreate(3) or imagecre-
atefrom* function.
The image format will be GIF87a unless the image has been made transparent with imagecolortransparent(3), in which case the image format
will be GIF89a.
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.
RETURN VALUES
Returns TRUE on success or FALSE on failure.
EXAMPLES
Example #1
Outputting an image using imagegif(3)
<?php
// Create a new image instance
$im = imagecreatetruecolor(100, 100);
// Make the background white
imagefilledrectangle($im, 0, 0, 99, 99, 0xFFFFFF);
// Draw a text string on the image
imagestring($im, 3, 40, 20, 'GD Library', 0xFFBA00);
// Output the image to browser
header('Content-Type: image/gif');
imagegif($im);
imagedestroy($im);
?>
Example #2
Converting a PNG image to GIF using imagegif(3)
<?php
// Load the PNG
$png = imagecreatefrompng('./php.png');
// Save the image as a GIF
imagegif($png, './php.gif');
// Free from memory
imagedestroy($png);
// We're done
echo 'Converted PNG image to GIF with success!';
?>
NOTES
Note
GIF support was removed from the GD library in Version 1.6, and added back in Version 2.0.28. This function is not available between
these versions. For more information, see the GD Project site.
The following code snippet allows you to write more portable PHP applications by auto-detecting the type of GD support which is
available. Replace the sequence header ("Content-Type: image/gif"); imagegif ($im); by the more flexible sequence:
<?php
// Create a new image instance
$im = imagecreatetruecolor(100, 100);
// Do some image operations here
// Handle output
if(function_exists('imagegif'))
{
// For GIF
header('Content-Type: image/gif');
imagegif($im);
}
elseif(function_exists('imagejpeg'))
{
// For JPEG
header('Content-Type: image/jpeg');
imagejpeg($im, NULL, 100);
}
elseif(function_exists('imagepng'))
{
// For PNG
header('Content-Type: image/png');
imagepng($im);
}
elseif(function_exists('imagewbmp'))
{
// For WBMP
header('Content-Type: image/vnd.wap.wbmp');
imagewbmp($im);
}
else
{
imagedestroy($im);
die('No image support in this PHP server');
}
// If image support was found for one of these
// formats, then free it from memory
if($im)
{
imagedestroy($im);
}
?>
Note
As of PHP 4.0.2 you can use the function imagetypes(3) in place of function_exists(3) for checking the presence of the various sup-
ported image formats:
<?php
if(imagetypes() & IMG_GIF)
{
header('Content-Type: image/gif');
imagegif($im);
}
elseif(imagetypes() & IMG_JPG)
{
/* ... etc. */
}
?>
