Functions

Rectangle waphics_rectangle_new(int x, int y, int width, int height);

Returns a new Rectangle with the specifed x, y, width and height.

Circle waphics_circle_new(int x, int y, int radius);

Returns a new Circle with the specified x, y and radius.

Surface waphics_display_new(uint32_t *pixels, unsigned int width, unsigned int height);

Returns a new Surface.

Note

All functions which return a new instance of a strcture have corrosponding macros:

#define RECT(x, y, w, h) waphics_rectangle_new(x, y, w, h)
#define CIRCLE(x, y, r) waphics_circle_new(x, y, r)
#define VECTOR2(x, y) waphics_vector2_new(x, y, z)
#define SCREEN(pixels, w, h) waphics_display_new(pixels, w, h)

void waphics_fill_display(Surface display, uint32_t color);

Fills the specified Surface with the specified color

Note

Colors should be in the following format: 0xAABBGGRR

Alternatily the RGBA or RGB macros can be used:

#define RGBA(r, g, b, a) ((((r)&0xFF)<<(8*0)) | (((g)&0xFF)<<(8*1)) | (((b)&0xFF)<<(8*2)) | (((a)&0xFF)<<(8*3)))
#define RGB(r, g, b) ((((r)&0xFF)<<(8*0)) | (((g)&0xFF)<<(8*1)) | (((b)&0xFF)<<(8*2)) | (((255)&0xFF)<<(8*3)))

void waphics_draw_rect(Surface display, Rectangle rect, uint32_t color);

Draws a rectangle with the given color

void waphics_draw_line(Surface display, int x1, int y1, int x2, int y2, int color);

Draws a line from point (x1, y1) to (x2, y2)

void waphics_draw_circle(Surface display, Circle circle, uint32_t color);

Draws a circle from the given Circle instance.

void waphics_draw_triangle(Surface display, Vector2 p1, Vector2 p2, Vector2 p3, uint32_t color);

Draws a triangle with points (x1, y1); (x2, y2); (x3, y3) with a flat color.

void waphics_draw_triangle_3(Surface display, Vector2 p1, Vector2 p2, Vector2 p3, uint32_t color1, uint32_t color2, uint32_t color3);

Draws a triangle with points (x1, y1); (x2, y2); (x3, y3) with a barycentric color interpolation between the 3 colors.

void waphics_draw_image(Surface display, Rectangle rect,
        uint32_t scale, uint32_t *pixels);

Draws an image from the gievn pixels scaled to the specified scale using the (x, y) coordiantes from the Rectangle for the top left of the image.

Note

On top of using the (x, y) coordiantes for the top left, the passed Rectangle should also have the width and height of the original image size. If you are using waphics_image_load this information can be found in the generated header file.

   void waphics_draw_image_alpha(Surface display, Rectangle rect,
         uint32_t scale, uint32_t *pixels, uint32_t alpha);

Identical to ``waphics_draw_image`` execept for blending each pixel with the specified alpha value.
