Member Function Documentation

eZImageObject::appendLayer	(	&$	imageLayer,
		$	parameters = array()
	)

Adds the image layer object $imageLayer to the end of the layer list with optional parameters $parameters

Returns:

the ID of the layer, the ID is unique per image object.

prependLayer

eZImageObject::calculateAxisPlacement	(	$	value,
		$	type,
		$	alignment,
		$	axisStart,
		$	axisStop,
		$	currentLength
	)

Figures out the absolute axis placement and returns it. The variable $type determines how $value is used, it can either be a constant value (self::PLACE_CONSTANT) or a relative value (self::PLACE_RELATIVE) where input value is placed relative to the length of the axis ($axisStop - $axisStart). $alignment determines where the axis should start, self::ALIGN_AXIS_NONE and self::ALIGN_AXIS_START will return the position from $axisStart towards $axisStop, self::ALIGN_AXIS_STOP returns the position from the $axisStop towards $axisStart while self::ALIGN_AXIS_CENTER returns the middle of $axisStart and $axisStop.

eZImageObject::calculatePosition	(	$	parameters,
		$	width,
		$	height
	)

Calculates the position for x and y parameters in $parameters and returns an absolute position in an array. The returned array will contain the x and y key.

eZImageObject::destroy

(

)

Cleans up the current image object if it is set.

Reimplemented from eZImageInterface.

Definition at line 210 of file ezimageobject.php.

eZImageObject::eZImageObject	(	$	imageObjectRef = null,
		$	imageObject = null,
		$	width = false,
		$	height = false
	)

Definition at line 35 of file ezimageobject.php.

eZImageObject::flatten

(

)

Goes trough all layers and merges them together into a single image. This image can then be displayed on the webpage.

eZImageObject::getTransparency

(

$

parameters

)

Returns:

the transparency value found in the parameters or 0 if no value is found.

eZImageObject::getTransparencyPercent

(

$

parameters

)

Returns:

the transparency percentage found in the parameters or 0 if no percentage is found.

eZImageObject::hasLayer

(

$

layerID

)

Returns:

true if the layer with ID $layerID exists in this image object.

Definition at line 201 of file ezimageobject.php.

eZImageObject::initializeAxis	(	$	parameters,
		$	name
	)

Initializes the axis from the parameter value $name filling in any missing values with defaults.

eZImageObject::prependLayer	(	&$	imageLayer,
		$	parameters = array()
	)

Adds the image layer object $imageLayer to the beginning of the layer list with optional parameters $parameters

Returns:

the ID of the layer, the ID is unique per image object.

eZImageObject::processImage

(

)

Flattens the image so that it can be displayed.

Reimplemented from eZImageInterface.

eZImageObject::removeLayer

(

$

layerID

)

Removes the layer with ID $layerID.

Returns:

true if succesful

eZImageObject::setTemplateURI

(

$

uri

)

Sets the URI of the template to use for displaying it using the template engine to $uri.

Definition at line 57 of file ezimageobject.php.

eZImageObject::templateData

(

)
