type factor =
Enumeration of the blending factors
The factors are mapped directly to their OpenGL equivalents, specified by glBlendFunc() or glBlendFuncSeparate().
type equation =
| Add | (* Pixel = Src * SrcFactor + Dst * DstFactor *) |
| Subtract | (* Pixel = Src * SrcFactor - Dst * DstFactor *) |
| ReverseSubtract | (* Pixel = Dst * DstFactor - Src * SrcFactor *) |
Enumeration of the blending equations
The equations are mapped directly to their OpenGL equivalents, specified by glBlendEquation() or glBlendEquationSeparate().
type t = {
color_src_factor : factor; | (* Source blending factor for the color channels *) |
color_dst_factor : factor; | (* Destination blending factor for the color channels *) |
color_equation : equation; | (* Blending equation for the color channels *) |
alpha_src_factor : factor; | (* Source blending factor for the alpha channel *) |
alpha_dst_factor : factor; | (* Destination blending factor for the alpha channel *) |
alpha_equation : equation; | (* Blending equation for the alpha channel *) |
}
Blending modes for drawing
Construct the blend mode given the factors and equation.
This constructor uses the same factors and equation for both color and alpha components. It also defaults to the Add equation.
val alpha : t
Commonly used blending modes
Blend source and dest according to dest alpha
val add : t
Blend source and dest according to dest alpha
Add source to dest
val multiply : t
Add source to dest
Multiply source and dest
val none : t
Multiply source and dest
Overwrite dest with source
