| Available since LÖVE 0.10.0 |
| It has been renamed from Canvas:getImageData. |
Generates ImageData from the contents of the Canvas.
|
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! |
Contents
Function
Synopsis
data = Canvas:newImageData( )
Arguments
None.
Returns
ImageData data- The new ImageData made from the Canvas' contents.
Function
| Available since LÖVE 11.0 |
| This variant is not supported in earlier versions. |
Synopsis
data = Canvas:newImageData( slice, mipmap, x, y, width, height )
Arguments
number slice- The cubemap face index, array index, or depth layer for cubemap, array, or volume type Canvases, respectively. This argument is ignored for regular 2D canvases.
number mipmap (1)- The mipmap index to use, for Canvases with mipmaps.
number x- The x-axis of the top-left corner (in pixels) of the area within the Canvas to capture.
number y- The y-axis of the top-left corner (in pixels) of the area within the Canvas to capture.
number width- The width in pixels of the area within the Canvas to capture.
number height- The height in pixels of the area within the Canvas to capture.
Returns
ImageData data- The new ImageData made from the Canvas' contents.
Function
| Removed in LÖVE 11.0 |
| This variant is not supported in that and later versions. |
Synopsis
