Creates a new ImageData object.

O.png This function can be slow if it is called repeatedly, such as from love.update or love.draw. If you need to use a specific resource often, create it once and store it somewhere it can be reused!  



Function

Synopsis

imageData = love.image.newImageData( width, height, format, rawdata )

Arguments

number width
The width of the ImageData.
number height
The height of the ImageData.
Available since LÖVE 11.0
PixelFormat format ("rgba8")
The pixel format of the ImageData.
string or Data rawdata (nil)
Optional raw byte data to load into the ImageData, in the format specified by format.

Returns

ImageData imageData
The new ImageData object. If data isn't supplied, each pixel's color values (including the alpha values!) will be set to zero.

Function

Synopsis

imageData = love.image.newImageData( filename )

Arguments

string filename
The filename of the image file.

Returns

ImageData imageData
The new ImageData object.

Function

Synopsis

imageData = love.image.newImageData( filedata )

Arguments

FileData filedata
