CompressedImageFormat

Available since LÖVE 0.9.0
This enum is not supported in earlier versions.

Compressed image data formats. Here is an overview of many of the formats.

Constants

dxt1
The DXT1 format. RGB data at 4 bits per pixel (compared to 32 bits for ImageData and regular Images.) Suitable for fully opaque images.
dxt3
The DXT3 format. RGBA data at 8 bits per pixel. Smooth variations in opacity do not mix well with this format.
dxt5
The DXT5 format. RGBA data at 8 bits per pixel. Recommended for images with varying opacity.
bc4
The BC4 format (also known as 3Dc+ or ATI1.) Stores just the red channel, at 4 bits per pixel.
bc4s
The signed variant of the BC4 format. Same as above but the pixel values in the texture are in the range of [-1, 1] instead of [0, 1] in shaders.
bc5
The BC5 format (also known as 3Dc or ATI2.) Stores red and green channels at 8 bits per pixel.
bc5s
The signed variant of the BC5 format.

Notes

Not all formats are supported on all systems, although the DXT formats are nearly ubiquitous. BC4 and BC5 are supported on systems with DX10 / OpenGL 3-capable hardware and drivers. Use love.graphics.isSupported to check.
