Canvas and Image texture formats.
Contents
Constants
- normal
- The default texture format: 8 bits per channel (32 bpp) RGBA. Color channel values range from 0-255 (0-1 in shaders.)
- hdr
- Only usable in Canvases. The high dynamic range texture format: floating point 16 bits per channel (64 bpp) RGBA. Color channel values inside the Canvas range from -infinity to +infinity.
Notes
The HDR format is most useful when combined with pixel shaders. Effects such as tonemapped HDR with bloom can be accomplished, or the canvas can be used to store arbitrary non-color data such as positions which are then interpreted and used in a shader, as long as you draw the right things to the canvas.
Not all systems which support Canvases will support the HDR format, use love.graphics.isSupported to check before creating the Canvas.
