assertValidImageHandle()

static assertValidImageHandle (   $handle )

static

Throws exception if the handle isn't a valid GD resource

Paramètres

mixed

$handle

isValidImageHandle()

static isValidImageHandle (   $handle )

bool

load()

static load (   $source )

static

Loads an image from a file, URL, HTML input file field, binary string, or a valid image handle. The image format is auto-detected.

Currently supported formats: PNG, GIF, JPG, BMP, TGA, GD, GD2.

This function analyzes the input and decides whether to use WideImage::loadFromHandle(), WideImage::loadFromFile(), WideImage::loadFromUpload() or WideImage::loadFromString(), all of which you can also call directly to spare WideImage some guessing.

Arrays are supported for upload fields; it returns an array of loaded images. To load only a single image from an array field, use WideImage::loadFromUpload('img', $i), where $i is the index of the image you want to load.

$img = WideImage::load('http://url/image.png'); // image URL $img = WideImage::load('/path/to/image.png'); // local file path $img = WideImage::load('img'); // upload field name $img = WideImage::load(imagecreatetruecolor(10, 10)); // a GD resource $img = WideImage::load($image_data); // binary string containing image data

Paramètres

mixed

$source

Voici le graphe d'appel pour cette fonction :

loadFromHandle()

static loadFromHandle (   $handle )

static

Create and load an image from an image handle.

Note: the resulting image object takes ownership of the passed handle. When the newly-created image object is destroyed, the handle is destroyed too, so it's not a valid image handle anymore. In order to preserve the handle for use after object destruction, you have to call \WideImage\Image::releaseHandle() on the created image instance prior to its destruction.

$handle = imagecreatefrompng('file.png'); $image = WideImage::loadFromHandle($handle);

Paramètres

resource

$handle

A valid GD image resource

loadFromString()

static loadFromString (   $string )

static

Create and load an image from a string. Format is auto-detected.

Paramètres

string

$string

Binary data, i.e. from BLOB field in the database

Voici le graphe d'appel pour cette fonction :

loadFromUpload()

static loadFromUpload (   $field_name,   $index = null  )

static

This method loads a file from the $_FILES array. The image format is auto-detected.

You only have to pass the field name as the parameter. For array fields, this function will return an array of image objects, unless you specify the $index parameter, which will load the desired image.

Paramètres

	$field_name	Name of the key in $_FILES array
int	$index	The index of the file to load (if the input field is an array)

\WideImage\Image The loaded image

path()

static path ( )

static

Returns the path to the library

string

registerCustomMapper()

static registerCustomMapper (   $mapper_class_name,   $mime_type,   $extension  )

static

Registers a custom mapper for image loading and saving

Example: \WideImage\WideImage::registerCustomMapper('\WideImage\Mapper\TGA', 'image/tga', 'tga');
