DESCRIPTION
Each of the mlib_GraphicsFillRectangle_*() functions draws a filled rectangle with the upper-left corner at (x, y), width w, and height h.
Each of the mlib_GraphicsFillRectangle_X_*() functions draws a filled rectangle in Xor mode as follows:
data[x,y] ^= c ^ c2
Each of the mlib_GraphicsFillRectangle_B_*() functions draws a filled rectangle with alpha blending as follows:
data[x,y] = (data[x,y] * (255 - a) + c * a) / 255
PARAMETERS
Each of the functions takes some of the following arguments:
buffer Pointer to the image into which the function is drawing.
x X coordinate of the upper-left corner of the rectangle.
y Y coordinate of the upper-left corner of the rectangle.
w Width of the rectangle.
h Height of the rectangle.
c Color used in the drawing.
c2 Alternation color.
a Alpha value for blending. 0 <= a <= 255.
RETURN VALUES
Each of the functions returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
