object Image ( )

Creates a new image object.

Example

$image = new Image;

bool url ( string $website )

Opens an image resource from specified $website. This image will be used in all of the methods that follow, and so must be called first.

$website	The url of the image you would like to work with.
Returns	True if successful, false if not.
Example	$image->url ('http://www.somesite.com/images/copy.jpg');

string type ( )

This is so that you can know what you are working with.

Returns	Either '.jpg', '.gif', or '.png'.
Example	$type = $image->type();

bool convert ( string $type )

If the image is a gif and you would like to covert it to a jpg for instance, you can do that here.

$type	Either 'jpg', 'gif', or 'png'.
Returns	True if successful, false if not.
Example	$image->convert ('jpg');

bool resize ( integer $width [, integer $height ] )

This will resize the original image within the width and height specified while still maintaining its original proportions. You can call this method as many times as you like, and you will always be working with the original image.

$width	The maximum width (in pixels) you would like this image to be.
$height	The maximum height (in pixels) you would like this image to be. This value defaults to 80% of whatever width is specified.
Returns	True if successful, false if not.
Example	$image->resize (500); // Takes the users massive 10 Megapixel image, and cuts it down to size for the web.

bool square ( integer $pixels )

This method will generate a square image of $pixels size.

$pixels	The size (in pixels) you would like the square to be.
Returns	True if successful, false if not.
Example	$image->square (80);

bool save ( string $location [, integer $quality= 80 ] )

This will save an image to the location on your server.

$location	Where you would like the image to reside on your server. Be sure to include the full directory path.
$quality	The quality of the image created from 0 (worst quality, smallest file size) to 100 (best quality, biggest file size). Default is 80.
Returns	True if successful, false if not.
Example	$image->save ('/base/directory/mysite.com/images/copied.jpg');

bool display ( [ integer $quality= 80 ] )

This method outputs the image directly to the browser.

$quality	The quality of the image created from 0 (worst quality, smallest file size) to 100 (best quality, biggest file size). Default is 80.
Returns	True if successful, false if not.
Example	$image->display (80);
