Synopsis

formats = love.graphics.getCanvasFormats( )

Arguments

None.

table formats
A table containing CanvasFormats as keys, and a boolean indicating whether the format is supported as values. Not all systems support all formats.

Examples

Create a canvas with the format 'rgba16f' if it is supported

if formats.rgba16f then
    canvas = love.graphics.newCanvas(800, 600, "rgba16f")
else
    -- The 'rgba16f' format isn't supported. We could have some fallback code, or trigger a message telling the user their system is unsupported.
end

Display a list of the canvas formats on the screen

canvasformats = love.graphics.getCanvasFormats()
 
function love.draw()
    local y = 0
    for formatname, formatsupported in pairs(canvasformats) do
        local str = string.format("Supports format '%s': %s", formatname, tostring(formatsupported))
        love.graphics.print(str, 10, y)
        y = y + 20
    end
