#include "splashkit.h"


int main()
{
    open_window("House Drawing", 800, 600);


    clear_screen(COLOR_WHITE);
    refresh_screen();
    delay(1000);
    fill_ellipse(COLOR_BRIGHT_GREEN, 0, 400, 800, 400);
    refresh_screen();
    delay(1000);
    fill_rectangle(COLOR_GRAY, 300, 300, 200, 200);
    refresh_screen();
    delay(1000);
    fill_triangle(COLOR_RED, 250, 300, 400, 150, 550, 300);
    refresh_screen();
    delay(5000);


    close_all_windows();


    return 0;
}

Draw Bitmap Examples*

Basic Bitmap Drawing

The following code shows an example of using Draw Bitmap to display a Bitmap image of the SplashKit logo in a graphics Window.

#include "splashkit.h"


int main()
{
    open_window("Basic Bitmap Drawing", 315, 330);


    load_bitmap("skbox", "skbox.png"); // Load bitmap image


    while (!quit_requested())
    {
        process_events();


        clear_screen(rgb_color(67, 80, 175));
        draw_bitmap("skbox", 50, 50); // draw bitmap image
        refresh_screen();
    }
    close_all_windows();


    return 0;
}

Output:

Fill Triangle Examples*

Simple Red Triangle

The following code demonstrates how to use the Fill Triangle function to draw a simple red-colored filled triangle. It creates a triangle with specified coordinates and fills it with red color.

#include "splashkit.h"


int main()
{
    open_window("Fill triangle Example", 800, 600);
    clear_screen();


    fill_triangle(COLOR_RED, 100, 100, 200, 200, 300, 100);
    refresh_screen();


    delay(5000);
    close_all_windows();


    return 0;
}

Output:

fill_triangle-1-basic-red example

Fill Triangle On Bitmap Examples*

Fill Triangle on Bitmap

The following code shows an example of using the Fill Triangle On Bitmap function to draw a red triangle on a loaded bitmap.

#include "splashkit.h"


int main()
{
    // Open a window
    open_window("Happy Hat", 618, 618);


    // Load the bitmaps for sad and smiling emojis (https://openmoji.org/library/#group=smileys-emotion)
    bitmap sad_emoji = load_bitmap("sad_emoji", "sad_emoji.png");
    bitmap smiling_emoji = load_bitmap("smiling_emoji", "smiling_emoji.png");


    // Draw the sad emoji and add a hat
    clear_screen(COLOR_BLACK);
    draw_bitmap(sad_emoji, 0, 0);
    refresh_screen();
    delay(1000);


    // Draw a triangle hat on the smiling emoji
    fill_triangle_on_bitmap(smiling_emoji, COLOR_RED, 100, 200, 309, 20, 520, 200);


    // Clear screen and switch to the smiling emoji
    clear_screen(COLOR_BLACK);
    draw_bitmap(smiling_emoji, 0, 0);
    refresh_screen();
    delay(1000);


    // Spin the smiling emoji with the hat
    for (int i = 0; i < 360; i++)
    {
        clear_screen(COLOR_BLACK);
        draw_bitmap(smiling_emoji, 0, 0, option_rotate_bmp(i));
        refresh_screen();
        delay(10);
    }


    // Free the bitmap resource
    free_all_bitmaps();
    // Close all windows
    close_all_windows();


    return 0;
}
