Constructor

OpenLayers.Pixel

Create a new OpenLayers.Pixel instance

Parameters

x	{Number} The x coordinate
y	{Number} The y coordinate

Returns

An instance of OpenLayers.Pixel

Functions

toString

toString:function()

Cast this object into a string

Returns

{String} The string representation of Pixel. ex: “x=200.4,y=242.2”

clone

clone:function()

Return a clone of this pixel object

Returns

{OpenLayers.Pixel} A clone pixel

equals

equals:function( px )

Determine whether one pixel is equivalent to another

Parameters

px	{<OpenLayers.Pixel>\|Object} An OpenLayers.Pixel or an object with a ‘x’ and ‘y’ properties.

Returns

{Boolean} The point passed in as parameter is equal to this. Note that if px passed in is null, returns false.

distanceTo

distanceTo:function( px )

Returns the distance to the pixel point passed in as a parameter.

Parameters

px	{OpenLayers.Pixel}

Returns

{Float} The pixel point passed in as parameter to calculate the distance to.

add

add:function( x,
y )

Parameters

x	{Integer}
y	{Integer}

Returns

{OpenLayers.Pixel} A new Pixel with this pixel’s x&y augmented by the values passed in.

offset

offset:function( px )

Parameters px - {<OpenLayers.Pixel>|Object} An OpenLayers.Pixel or an object with a ‘x’ and ‘y’ properties.

Returns

{OpenLayers.Pixel} A new Pixel with this pixel’s x&y augmented by the x&y values of the pixel passed in.
