pygame.gfxdraw

pygame module for drawing shapes

EXPERIMENTAL!: meaning this API may change, or disappear in later pygame releases. If you use this, your code will break with the next pygame release.

Draw several shapes to a surface.

Most of the functions accept a color argument that is an RGB triplet. These can also accept an RGBA quadruplet. The color argument can also be an integer pixel value that is already mapped to the Surface's pixel format.

For all functions the arguments are strictly positional. Only integers are accepted for coordinates and radii.

For functions like rectangle that accept a rect argument any (x, y, w, h) sequence is accepted, though pygame.Rect instances are preferred. Note that for a pygame.Rect the drawing will not include Rect.bottomright. The right and bottom attributes of a Rect lie one pixel outside of the Rect's boarder.

To draw an anti aliased and filled shape, first use the aa* version of the function, and then use the filled version. For example

col = (255, 0, 0)
surf.fill((255, 255, 255))
pygame.gfxdraw.aacircle(surf, x, y, 30, col)
pygame.gfxdraw.filled_circle(surf, x, y, 30, col)

Note that pygame does not automatically import pygame.gfxdraw, so you need to import pygame.gfxdraw before using it.

Threading note: each of the functions releases the GIL during the C part of the call.

The pygame.gfxdraw module differs from the draw module in the API it uses, and also the different functions available to draw. It also wraps the primitives from the library called SDL_gfx, rather than using modified versions.

pygame.gfxdraw.pixel(surface, x, y, color) -> None

place a pixel

Draws a single pixel onto a surface.

pygame.gfxdraw.hline(surface, x1, x2, y, color) -> None

draw a horizontal line

Draws a straight horizontal line on a Surface from x1 to x2 for the given y coordinate.

pygame.gfxdraw.vline(surface, x, y1, y2, color) -> None

draw a vertical line

Draws a straight vertical line on a Surface from y1 to y2 on the given x coordinate.

pygame.gfxdraw.rectangle(surface, rect, color) -> None

draw a rectangle

Draws the rectangle edges onto the surface. The given Rect is the area of the rectangle.

Keep in mind the Surface.fill() method works just as well for drawing filled rectangles. In fact the Surface.fill() can be hardware accelerated on some platforms with both software and hardware display modes.

pygame.gfxdraw.box(surface, rect, color) -> None

draw a box

Draws a box (a rect) onto a surface.

pygame.gfxdraw.line(surface, x1, y1, x2, y2, color) -> None

draw a line

Draws a straight line on a Surface. There are no endcaps.

pygame.gfxdraw.circle(surface, x, y, r, color) -> None

draw a circle

Draws the edges of a circular shape on the Surface. The pos argument is the center of the circle, and radius is the size. The circle is not filled with color.

pygame.gfxdraw.arc(surface, x, y, r, start, end, color) -> None

draw an arc

Draws an arc onto a surface.

pygame.gfxdraw.aacircle(surface, x, y, r, color) -> None

draw an anti-aliased circle

Draws the edges of an anti aliased circle onto a surface.

pygame.gfxdraw.filled_circle(surface, x, y, r, color) -> None

draw a filled circle

Draws a filled circle onto a surface. So the inside of the circle will be filled with the given color.

pygame.gfxdraw.ellipse(surface, x, y, rx, ry, color) -> None

draw an ellipse

Draws the edges of an ellipse onto a surface.

pygame.gfxdraw.aaellipse(surface, x, y, rx, ry, color) -> None

draw an anti-aliased ellipse

Draws anti aliased edges of an ellipse onto a surface.

pygame.gfxdraw.filled_ellipse(surface, x, y, rx, ry, color) -> None

draw a filled ellipse

Draws a filled ellipse onto a surface. So the inside of the ellipse will be filled with the given color.

pygame.gfxdraw.pie(surface, x, y, r, start, end, color) -> None

draw a pie

Draws a pie onto the surface.

pygame.gfxdraw.trigon(surface, x1, y1, x2, y2, x3, y3, color) -> None

draw a triangle

Draws the edges of a trigon onto a surface. A trigon is a triangle.

pygame.gfxdraw.aatrigon(surface, x1, y1, x2, y2, x3, y3, color) -> None

draw an anti-aliased triangle

Draws the anti aliased edges of a trigon onto a surface. A trigon is a triangle.

pygame.gfxdraw.filled_trigon(surface, x1, y1, x2, y2, x3, y3, color) -> None

draw a filled trigon

Draws a filled trigon onto a surface. So the inside of the trigon will be filled with the given color.

pygame.gfxdraw.polygon(surface, points, color) -> None

draw a polygon

Draws the edges of a polygon onto a surface.

pygame.gfxdraw.aapolygon(surface, points, color) -> None

draw an anti-aliased polygon

Draws the anti aliased edges of a polygon onto a surface.

pygame.gfxdraw.filled_polygon(surface, points, color) -> None

draw a filled polygon

Draws a filled polygon onto a surface. So the inside of the polygon will be filled with the given color.

pygame.gfxdraw.textured_polygon(surface, points, texture, tx, ty) -> None

draw a textured polygon

Draws a textured polygon onto a surface.

A per-pixel alpha texture blit to a per-pixel alpha surface will differ from a Surface.blit() blit. Also, a per-pixel alpha texture cannot be used with an 8-bit per pixel destination.

pygame.gfxdraw.bezier(surface, points, steps, color) -> None

draw a Bézier curve

Draws a Bézier curve onto a surface.
