Description

Each of the mlib_GraphicsDrawLine_*() functions draws a line between (x1,y1) and (x2,y2).

Each of the mlib_GraphicsDrawLine_X_*() functions draws a line between (x1,y1) and (x2,y2) in Xor mode as follows:

    data[x,y] ^= c ^ c2

Each of the mlib_GraphicsDrawLine_A_*() functions draws a line between (x1,y1) and (x2,y2) with antialiasing.

Each of the mlib_GraphicsDrawLine_B_*() functions draws a line between (x1,y1) and (x2,y2) with alpha blending as follows:

    data[x,y] = (data[x,y] * (255 - a) + c * a) / 255

Each of the mlib_GraphicsDrawLine_G_*() functions draws a line between (x1,y1) and (x2,y2) with Gouraud shading.

Each of the mlib_GraphicsDrawLine_Z_*() functions draws a line between (x1,y1) and (x2,y2) with Z buffering.

Each of the other functions draws a line between (x1,y1) and (x2,y2) with a combination of two or more features like antialiasing (A), alpha blending (B), Gouraud shading (G), and Z buffering (Z).

Parameters

Each of the functions takes some of the following arguments:

buffer

Pointer to the image into which the function is drawing.

zbuffer

Pointer to the image that holds the Z buffer.

x1

X coordinate of the first point.

y1

Y coordinate of the first point.

z1

Z coordinate of the first point.

x2

X coordinate of the second point.

y2

Y coordinate of the second point.

z2

Z coordinate of the second point.

c

Color used in the drawing.

c1

Color of the first point.

c2

Color of the second point, or the alternation color in the Xor mode.

a

Alpha value for blending. 0 ≤ a ≤ 255.

Return Values

Each of the functions returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
