Functions

draw_antialiased_line_segment	Draws as much of the line segment between start and end as lies inside the image bounds. The parameters of blend are (line_color, original_color, line_weight). Uses Xu's line drawing algorithm.
draw_antialiased_line_segment_mut	Draws as much of the line segment between start and end as lies inside the image bounds. The parameters of blend are (line_color, original_color, line_weight). Uses Xu's line drawing algorithm.
draw_convex_polygon	Draws as much of a filled convex polygon as lies within image bounds. The provided list of points should be an open path, i.e. the first and last points must not be equal. An implicit edge is added from the last to the first point in the slice.
draw_convex_polygon_mut	Draws as much of a filled convex polygon as lies within image bounds. The provided list of points should be an open path, i.e. the first and last points must not be equal. An implicit edge is added from the last to the first point in the slice.
draw_cross	Draws a colored cross on an image. Handles coordinates outside image bounds.
draw_cross_mut	Draws a colored cross on an image in place. Handles coordinates outside image bounds.
draw_filled_circle	Draw as much of a circle and its contents as lies inside the image bounds.
draw_filled_circle_mut	Draw as much of a circle, including its contents, as lies inside the image bounds.
draw_filled_rect	Draw as much of a rectangle, including its boundary, as lies inside the image bounds.
draw_filled_rect_mut	Draw as much of a rectangle, including its boundary, as lies inside the image bounds.
draw_hollow_circle	Draw as much of a circle as lies inside the image bounds.
draw_hollow_circle_mut	Draw as much of a circle as lies inside the image bounds.
draw_hollow_rect	Draws as much of the boundary of a rectangle as lies inside the image bounds.
draw_hollow_rect_mut	Draws as much of the boundary of a rectangle as lies inside the image bounds.
draw_line_segment	Draws as much of the line segment between start and end as lies inside the image bounds. Uses Bresenham's line drawing algorithm.
draw_line_segment_mut	Draws as much of the line segment between start and end as lies inside the image bounds. Uses Bresenham's line drawing algorithm.
